\n \n \n \n\n```\n\n### File structure\n\n```\nfrontend/\n shell.ts — HTML wrapper (head, props injection, script tag)\n theme.ts — styled-components theme tokens, shared\n components/ — shared across pages (Card, Button, StatusText, Toast...)\n pages/\n landing/\n LandingPage.tsx — isomorphic component\n client.tsx — hydrateRoot entry\n dashboard/\n DashboardPage.tsx — isomorphic component\n client.tsx — hydrateRoot entry\n docs/\n DocPage.tsx — isomorphic component\n client.tsx — hydrateRoot entry\n authorize/\n AuthorizePage.tsx — OAuth sign-in/register + consent\n client.tsx — hydrateRoot entry\n manage/\n ManagePage.tsx — Vault, passkeys, recovery management\n client.tsx — hydrateRoot entry\n recover/\n RecoverPage.tsx — Recovery token → new passkey\n client.tsx — hydrateRoot entry\n```\n\n---\n\n## Domain Unification\n\n### Merging mcp/mcp.ts into main.ts\n\nThe MCP HTTP handler becomes a function imported by `main.ts`, not a separate entry point.\n\n```typescript\n// main.ts\nimport { handleMcpRequest } from \"./mcp/mcp.ts\";\n\n// In the route handler, before room routes:\nif (url.pathname.startsWith(\"/mcp\") ||\n url.pathname.startsWith(\"/oauth/\") ||\n url.pathname.startsWith(\"/webauthn/\") ||\n url.pathname.startsWith(\"/manage\") ||\n url.pathname.startsWith(\"/recover\") ||\n url.pathname.startsWith(\"/vault\") ||\n url.pathname.startsWith(\"/.well-known/oauth\")) {\n return handleMcpRequest(req);\n}\n```\n\n`mcp/mcp.ts` changes from `export default async function` to\n`export async function handleMcpRequest(req: Request): Promise`.\n\n### What changes for MCP clients\n\n- MCP server URL: `mcp.sync.parc.land` → `sync.parc.land` (or `sync.parc.land/mcp`)\n- OAuth discovery URLs: issuer changes to `https://sync.parc.land`\n- Claude.ai connector config needs updating\n- Existing tokens should survive (same DB, validation doesn't check issuer)\n\n### What stays the same\n\n- All API endpoints (paths unchanged)\n- SQLite database (shared, same as today)\n- WebAuthn RP ID (`parc.land` — domain-level, unaffected)\n- Token format and validation\n\n---\n\n## Route Map (after unification)\n\n| Path | Method | Handler | Page/Response |\n|------|--------|---------|---------------|\n| `/` | GET | main.ts | SSR LandingPage |\n| `/?room=X` | GET | main.ts | SSR DashboardPage |\n| `/?doc=X` | GET | main.ts | SSR DocPage |\n| `/manage` | GET | main.ts → mcp | SSR ManagePage |\n| `/recover` | GET | main.ts → mcp | SSR RecoverPage |\n| `/oauth/authorize` | GET | main.ts → mcp | SSR AuthorizePage |\n| `/mcp` | POST | main.ts → mcp | MCP JSON-RPC |\n| `/oauth/*` | POST | main.ts → mcp | OAuth API |\n| `/webauthn/*` | POST | main.ts → mcp | WebAuthn API |\n| `/manage/api/*` | * | main.ts → mcp | Management API |\n| `/recover/*` | POST | main.ts → mcp | Recovery API |\n| `/vault` | * | main.ts → mcp | Vault API |\n| `/.well-known/*` | GET | main.ts → mcp | OAuth discovery |\n| `/rooms/*` | * | main.ts | Room API |\n| `/frontend/*` | GET | main.ts | Module proxy (esm.town) |\n| `/reference/*` | GET | main.ts | Reference docs |\n\n---\n\n## Design System\n\n### Unified theme\n\nAdopt the sync dashboard palette as the single source of truth. The MCP pages'\nslightly different dark theme (#0a0a0f vs #0d1117, #4a4aff vs #58a6ff) converges\nto the dashboard variables.\n\n```typescript\n// frontend/theme.ts\nexport const theme = {\n bg: '#0d1117',\n fg: '#c9d1d9',\n dim: '#484f58',\n border: '#21262d',\n accent: '#58a6ff',\n green: '#3fb950',\n yellow: '#d29922',\n red: '#f85149',\n surface: '#161b22',\n surface2: '#1c2129',\n purple: '#bc8cff',\n orange: '#f0883e',\n // Landing/docs (light default, dark media query)\n landing: { ... },\n};\n```\n\n### Shared components\n\n```\nfrontend/components/\n Card.tsx — Surface container\n Button.tsx — Primary, secondary variants\n StatusText.tsx — Status/error messages\n Toast.tsx — Toast notifications\n TokenBadge.tsx — Token type badges (room/agent/view)\n PasskeyChip.tsx — Passkey credential display\n VaultTable.tsx — Token vault table with actions\n```\n\n---\n\n## WebAuthn\n\n### ESM import (replaces UMD script tag)\n\n```typescript\nimport {\n startRegistration,\n startAuthentication,\n} from \"https://esm.sh/@simplewebauthn/browser@13\";\n```\n\nThis is client-only — used in hydration scripts, not in SSR.\n\n### Shared hook\n\n```typescript\n// frontend/hooks/useWebAuthn.ts\nexport function useWebAuthn(origin: string) {\n const [status, setStatus] = useState(\"\");\n const [error, setError] = useState(\"\");\n // signIn(): Promise — returns sessionId\n // register(username): Promise<{ sessionId } | null>\n return { signIn, register, status, error, setError };\n}\n```\n\n### Progressive enhancement\n\nWebAuthn requires JS (browser API). Forms that don't need WebAuthn can work\nwithout JS via `

`. The server handles the POST,\nre-renders the page with updated state.\n\nPages that require WebAuthn (all three MCP pages):\n- Server renders the initial state (sign-in form, token input, etc.)\n- Client hydration adds the WebAuthn interaction\n- Without JS: page renders but WebAuthn buttons are inert (acceptable — passkeys\n require JS anyway)\n\n---\n\n## Implementation Sequence\n\n### Phase 1: Infrastructure\n\n1. Create `frontend/shell.ts` — SSR HTML wrapper\n2. Create `frontend/theme.ts` — shared design tokens\n3. Create `frontend/components/` shared components\n4. Verify `styled-components` ServerStyleSheet works in Val.town Deno runtime\n\n### Phase 2: Migrate existing pages to SSR\n\n5. Convert LandingPage to SSR + hydration (replaces SPA)\n6. Convert DashboardPage to SSR + hydration\n7. Convert DocPage to SSR + hydration\n8. Remove React Router dependency\n9. Update main.ts to SSR each page\n\n### Phase 3: Domain unification\n\n10. Convert `mcp/mcp.ts` from default export to named export\n11. Import handleMcpRequest in main.ts, add route delegation\n12. Test all MCP endpoints work on sync.parc.land\n13. Update OAuth discovery metadata (issuer URL)\n\n### Phase 4: MCP auth pages as React SSR\n\n14. Create RecoverPage.tsx (simplest — proof of pattern)\n15. Create ManagePage.tsx (medium complexity)\n16. Create AuthorizePage.tsx (most complex — OAuth flow critical path)\n17. Create client.tsx hydration entries for each\n18. Create useWebAuthn hook\n19. Add authorize params validation endpoint (`GET /oauth/authorize/params`)\n\n### Phase 5: Cleanup\n\n20. Delete inline HTML templates from mcp/auth.ts (~600 lines)\n21. Delete CSS constant\n22. Delete escapeHtml function\n23. Remove mcp/mcp.ts as HTTP entry point (becomes plain module)\n24. Update MCP client configs (Claude.ai connector)\n25. Test OAuth flow end-to-end\n\n---\n\n## Risks & Mitigations\n\n| Risk | Severity | Mitigation |\n|------|----------|------------|\n| styled-components ServerStyleSheet fails in Deno | High | Test early in Phase 1. Fallback: inline `\n\n\n

Authenticate once with a passkey, then create rooms, join as agents,\ninvoke actions, and send messages — no tokens to copy-paste.\n\n**Live endpoint:** `https://mcp.sync.parc.land/mcp`\n\n## What is sync?\n\nsync is a coordination layer for multi-agent systems. Agents (human or AI) join\n**rooms**, observe shared **state**, invoke **actions** that mutate state\natomically, and communicate via **messages**. Everything is expressed through\n[CEL](https://cel.dev/) expressions and a small set of primitives.\n\nsync-mcp exposes the full sync API as 16 MCP tools, so any MCP-compatible client\ncan participate as a first-class agent.\n\n## Quick start\n\n### Claude.ai (web / mobile / desktop app)\n\n1. Open **Settings → Connectors** (or click the tools icon → **Manage\n   Connectors**)\n2. Click **Add custom connector**\n3. Enter the server URL:\n   ```\n   https://mcp.sync.parc.land/mcp\n   ```\n4. Click **Add**\n5. When prompted, **register a passkey** (or sign in if you already have one)\n   and **grant consent**\n\nThat's it. Claude now has access to all 16 sync tools. Try asking:\n\n> \"Create a new sync room called 'planning' and send a hello message.\"\n\n### Claude Code (CLI)\n\nAdd sync-mcp as a remote HTTP server. Pick the scope that fits your use case:\n\n**User scope** — available across all your projects:\n\n```bash\nclaude mcp add --transport http sync-mcp --scope user https://mcp.sync.parc.land/mcp\n```\n\n**Local scope** — current project only (default):\n\n```bash\nclaude mcp add --transport http sync-mcp https://mcp.sync.parc.land/mcp\n```\n\n**Project scope** — shared with your team via `.mcp.json`:\n\n```bash\nclaude mcp add --transport http sync-mcp --scope project https://mcp.sync.parc.land/mcp\n```\n\nThen authenticate:\n\n```bash\n# Inside Claude Code, trigger the OAuth flow:\n/mcp\n# Select sync-mcp → Authenticate → complete passkey registration in browser\n```\n\nVerify the connection:\n\n```bash\nclaude mcp list\nclaude mcp get sync-mcp\n```\n\n### Manual JSON configuration\n\nIf you prefer editing config files directly, add this to your configuration:\n\n**Claude Code** (`~/.claude.json` for user scope, or `.mcp.json` at project root\nfor project scope):\n\n```json\n{\n  \"mcpServers\": {\n    \"sync-mcp\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.sync.parc.land/mcp\"\n    }\n  }\n}\n```\n\n**Claude Desktop** (`claude_desktop_config.json`):\n\n```json\n{\n  \"mcpServers\": {\n    \"sync-mcp\": {\n      \"command\": \"npx\",\n      \"args\": [\"mcp-remote\", \"https://mcp.sync.parc.land/mcp\"]\n    }\n  }\n}\n```\n\nAfter editing config files, restart the client for changes to take effect.\n\n## Authentication\n\nsync-mcp uses **OAuth 2.1 with WebAuthn passkeys** — no passwords, no API keys.\n\nThe first time an MCP client connects, the server returns an HTTP 401 with a\n`WWW-Authenticate` header pointing to the OAuth discovery endpoints. The client\n(Claude) handles the flow automatically:\n\n1. **Discovery** — client fetches `/.well-known/oauth-protected-resource` →\n   `/.well-known/oauth-authorization-server`\n2. **Client registration** — client registers itself via Dynamic Client\n   Registration (DCR)\n3. **Authorization** — client opens the authorize page in your browser\n4. **Passkey** — you register a new passkey (or sign in with an existing one)\n5. **Consent** — you approve access for the MCP client\n6. **Token exchange** — client receives an OAuth access token (1 hour,\n   auto-refreshed)\n\nAll subsequent tool calls are authenticated automatically. Tokens refresh\ntransparently via refresh tokens (30-day lifetime).\n\n### Token vault\n\nWhen authenticated, sync tokens are automatically stored in your personal\n**vault**:\n\n- Creating a room → room token + view token auto-vaulted\n- Joining a room as an agent → agent token auto-vaulted\n- Setting a default room → subsequent calls resolve room + token automatically\n\nThis means most tool calls need **zero parameters** — the server resolves your\nroom and token from the vault. You can still pass explicit `room` and `token`\nparameters to override vault resolution.\n\n### Backward compatibility\n\nIf you can't or don't want to use OAuth, every tool still accepts explicit\n`room` and `token` parameters. The server works with or without authentication —\nOAuth just removes the friction of passing tokens on every call.\n\n## Tools\n\nsync-mcp exposes 16 tools organized around sync's core concepts:\n\n### Room lifecycle\n\n| Tool               | Description                                                |\n| ------------------ | ---------------------------------------------------------- |\n| `sync_create_room` | Create a new room. Auto-vaults tokens when authenticated.  |\n| `sync_list_rooms`  | List rooms accessible with current auth or explicit token. |\n| `sync_join_room`   | Join a room as an agent. Auto-vaults agent token.          |\n\n### Core rhythm (read → act)\n\n| Tool                 | Description                                                                                                                     |\n| -------------------- | ------------------------------------------------------------------------------------------------------------------------------- |\n| `sync_read_context`  | **The primary read.** Returns state, views, agents, actions, messages. Supports context shaping via `depth`, `only`, `compact`. |\n| `sync_invoke_action` | **The primary write.** Invoke any action (built-in or custom). All state mutations flow through actions.                        |\n| `sync_wait`          | Block until a CEL condition becomes true (max 25s). For event-driven coordination.                                              |\n\n### Registration\n\n| Tool                   | Description                                                                         |\n| ---------------------- | ----------------------------------------------------------------------------------- |\n| `sync_register_action` | Register a new action — define write effects, preconditions, parameters, cooldowns. |\n| `sync_register_view`   | Register a computed view — a named CEL expression for derived state.                |\n\n### Messaging\n\n| Tool                | Description                                                                                     |\n| ------------------- | ----------------------------------------------------------------------------------------------- |\n| `sync_send_message` | Send a message. Supports `kind` (chat, proposal, etc.) and `to` for directed attention routing. |\n\n### Utilities\n\n| Tool                 | Description                                                              |\n| -------------------- | ------------------------------------------------------------------------ |\n| `sync_help`          | Access the help system — guides, standard library, vocabulary bootstrap. |\n| `sync_eval_cel`      | Evaluate a CEL expression against current room state.                    |\n| `sync_delete_action` | Remove an action from a room.                                            |\n| `sync_delete_view`   | Remove a view from a room.                                               |\n\n### Vault management\n\n| Tool                | Description                                                                |\n| ------------------- | -------------------------------------------------------------------------- |\n| `sync_vault_list`   | List all stored tokens (room, agent, view) with their labels and defaults. |\n| `sync_vault_store`  | Manually store a sync token in the vault.                                  |\n| `sync_vault_remove` | Remove a token from the vault.                                             |\n\n## Typical workflow\n\nHere's what a typical session looks like once authenticated:\n\n```\nYou: Create a room called \"sprint-planning\" and make it my default.\n\nClaude: [sync_create_room] → room created, tokens vaulted, set as default\n\nYou: Join as an agent named \"facilitator\".\n\nClaude: [sync_join_room] → joined, agent token vaulted\n\nYou: Register an action called \"add_item\" that appends to a backlog list.\n\nClaude: [sync_register_action] → action registered with write template\n\nYou: Add \"Fix login bug\" to the backlog.\n\nClaude: [sync_invoke_action: add_item] → item appended to state\n\nYou: What's the current state?\n\nClaude: [sync_read_context] → shows backlog, agents, actions, messages\n```\n\nNo room IDs or tokens needed in any of those calls — everything resolves from\nthe vault.\n\n## Architecture\n\n```\n┌─────────────┐     OAuth 2.1      ┌──────────────────┐\n│  MCP Client

uses `parc.land`\nas the stable RP ID, so passkeys work on any `*.parc.land` origin (e.g.\n`mcp.sync.parc.land`, `auth.parc.land`). On non-`parc.land` hostnames (like\nVal.town dev endpoints), the RP ID falls back to the request hostname — giving\neach dev endpoint its own isolated passkeys.\n\n**Recovery tokens** let you register a new passkey on a different hostname while\nkeeping your existing account, vault, and rooms. Generate one at `/manage`, then\nuse it at `/recover` on the new hostname. Useful for domain migrations, device\nloss, or bridging between production and dev passkeys.\n\n## Self-hosting\n\nsync-mcp runs on [Val.town](https://val.town). To fork and run your own\ninstance:\n\n1. Fork the `c15r/sync-mcp` val on Val.town\n2. Set the `WEBAUTHN_RP_ID` environment variable to your domain (e.g.\n   `example.com`)\n3. Optionally set the `SYNC_URL` environment variable (defaults to\n   `https://sync.parc.land`)\n4. Configure a custom domain pointing to the val's HTTP endpoint\n5. The HTTP handler in `main.ts` starts serving immediately\n\nThe SQLite database is automatically provisioned per-val by Val.town. Set\n`WEBAUTHN_RP_ID` to your root domain so passkeys survive hostname changes.\nWithout it, passkeys bind to the request hostname.\n\n## Standards\n\n- **MCP**: [Model Context Protocol](https://modelcontextprotocol.io/) —\n  Streamable HTTP transport, JSON-RPC 2.0\n- **OAuth 2.1**: Authorization Code + PKCE (S256), refresh token rotation,\n  Dynamic Client Registration\n-

Full admin (`*` scope authority, read + write).\n- **View token** (`view_...`): returned on room creation. Read-only access to all scopes (no mutations).\n- **Agent token** (`as_...`): returned on agent join. Own-scope authority + grants.\n- All mutations require `Authorization: Bearer ` header with a room or agent token.\n- View tokens are blocked from all mutations with `403 read_only_token`.\n\n## Global Query Params\n\n- `compact=true` — strip null/empty fields from all JSON responses.\n\n---\n\n## Rooms\n\n### POST /rooms\nCreate a room. Returns room token for admin access.\n\n```json\n// Request\n{ \"id\": \"my-room\", \"meta\": { \"name\": \"My Room\" } }\n\n// Response 201\n{ \"id\": \"my-room\", \"created_at\": \"...\", \"meta\": \"{...}\", \"token\": \"room_...\", \"view_token\": \"view_...\" }\n```\n\n### GET /rooms\nList rooms visible to the authenticated token.\n\n### GET /rooms/:id\nGet room info.\n\n### POST /rooms/:id/rotate-view-token\n**Requires room token.** Regenerate the view token, invalidating the previous one.\n\n```json\n// Response 200\n{ \"ok\": true, \"view_token\": \"view_...\" }\n```\n\n### POST /rooms/:id/generate-view-token\n**Requires room token.** Generate a view token for rooms created before view tokens existed.\nReturns 409 if the room already has one — use `rotate-view-token` instead.\n\n---\n\n## Agents\n\n### POST /rooms/:id/agents\nJoin a room. Returns agent token.\n\n```json\n// Basic join\n{ \"id\": \"agent-a\", \"name\": \"Alice\", \"role\": \"warrior\" }\n\n// Join with private state and views (recommended)\n{ \"id\": \"agent-a\", \"name\": \"Alice\", \"role\": \"warrior\",\n  \"state\": { \"health\": 100, \"inventory\": [\"sword\"] },\n  \"public_keys\": [\"health\"],\n  \"views\": [\n    { \"id\": \"alice-combat\", \"expr\": \"state[\\\"alice\\\"][\\\"health\\\"] > 50 ? \\\"ready\\\" : \\\"wounded\\\"\" }\n  ]}\n\n// Response 201\n{ \"id\": \"agent-a\", \"name\": \"Alice\", \"role\": \"warrior\", \"token\": \"as_...\", \"grants\": \"[]\", ... }\n```\n\n**Inline state:** `state` object writes key-value pairs to the agent's private scope.\n**public_keys:** Array of key names from `state` to auto-create views for (equivalent to `\"public\": true`).\n**Inline views:** Array of view definitions scoped to this agent. Each needs `id` and `expr`.\n\nRe-joining: provide existing agent token or room token in Authorization header.\n\n### PATCH /rooms/:id/agents/:agent-id\n**Requires room token.** Update agent grants, role, name, meta.\n\n```json\n{ \"grants\": [\"_shared\", \"_messages\"] }\n```\n\n---\n\n## Context (primary read endpoint)\n\n### GET /rooms/:id/context\nReturns everything an agent needs in one call: state, views, agents, actions\n(with descriptions and params), and messages (with bodies).\n\n**Query params:**\n- `only` — comma-separated sections: `state`, `views`, `agents`, `actions`, `messages`, or `state._shared`\n- `messages_after` — only messages with seq > N (for pagination)\n- `messages_limit` — max message bodies (default 50, max 200)\n\n```json\n// GET /rooms/my-room/context  (as alice)\n{\n  \"state\": {\n    \"_shared\": { \"phase\": \"playing\", \"turn\": 3 },\n    \"self\": { \"health\": 80, \"inventory\": [\"sword\", \"potion\"] }\n  },\n  \"views\": {\n    \"alice.health\": 80,\n    \"alice-combat\": \"ready\",\n    \"bob.health\": 65\n  },\n  \"agents\": {\n    \"alice\": { \"name\": \"Alice\", \"role\": \"warrior\", \"status\": \"active\" },\n    \"bob\": { \"name\": \"Bob\", \"role\": \"healer\", \"status\": \"waiting\" }\n  },\n  \"actions\": {\n    \"attack\": {\n      \"available\": true, \"enabled\": true,\n      \"description\": \"Attack a target\",\n      \"params\": { \"target\": { \"type\": \"string\", \"enum\": [\"goblin\", \"dragon\"] } },\n      \"writes\": [{ \"scope\": \"_shared\", \"key\": \"last_attack\", \"value\": { \"by\": \"${self}\", \"target\": \"${params.target}\" } }]\n    },\n    \"_send_message\": {\n      \"available\": true, \"enabled\": true, \"builtin\": true,\n      \"description\": \"Send a message to the room\",\n      \"params\": { \"body\": { \"type\": \"string\" }, \"kind\": { \"type\": \"string\" } }\n    }\n  },\n  \"messages\": {\n    \"count\": 12, \"unread\": 3, \"directed_unread\": 1,\n    \"recent\": [\n      { \"seq\": 10, \"from\": \"alice\", \"kind\": \"chat\", \"body\": \"hello\" },\n      { \"seq\": 11, \"from\": \"bob\", \"to\": [\"alice\"], \"kind\": \"negotiation\", \"body\": \"...\" },\n      { \"seq\": 12, \"from\": \"alice\", \"kind\": \"chat\", \"body\": \"thanks\" }\n    ]\n  },\n  \"_context\": { \"depth\": \"lean\", \"help\": [] },\n  \"self\": \"alice\"\n}\n```\n\n**Scope privacy:** Agent tokens see system scopes + own scope (as `self`) + view projections.\nRoom and view tokens see all scopes. Bob cannot see Alice's raw state — only her view projections.\n\n**Action writes in context:** Custom actions include their `writes` templates in the context\nresponse, letting agents inspect what an action will do before invoking it.\n\nReading context updates `last_seen_seq`, marking messages as read.\n\n### GET /rooms/:id/poll\nDashboard-optimized bundle. Returns agents, state, messages, actions, views, and audit log.\nUnlike `/context`, returns raw row data suitable for debugging UIs.\n\n**Query params:**\n- `messages_limit` — max messages (default 500, max 2000)\n- `audit_limit` — max audit entries (default 500, max 2000)\n\nState tab excludes `_messages` and `_audit` scopes (those have dedicated sections).\n\n---\n\n## Wait\n\n### GET /rooms/:id/wait\nBlock until a CEL condition becomes true. Returns full context by default.\n\n**Query params:**\n- `condition` — CEL expression (required)\n- `agent` — agent ID for status tracking (defaults to auth identity)\n- `timeout` — max wait ms (default/max 25000)\n- `include` — `context` (default) returns full context; or comma-separated: `state`, `agents`, `messages`, `actions`, `views`\n\n```\nGET /rooms/my-room/wait?condition=messages.unread>0\n→ { \"triggered\": true, \"condition\": \"...\", \"context\": { \"state\": {...}, \"views\": {...}, \"messages\": { \"recent\": [...] }, ... } }\n```\n\n---\n\n## Actions (the write endpoint)\n\n### POST /rooms/:id/actions/:action-id/invoke\nInvoke an action (user-registered or built-in). **Requires auth.**\n\n```json\n{ \"params\": { \"target\": \"goblin\" } }\n```\n\nThis is the only write endpoint. All state mutations, messages, registrations,\nand deletions flow through action invocation. Every invocation is logged to the\n`_audit` scope for traceability.\n\n**Built-in actions** are available in every room:\n\n| Action | Description | Key params |\n|--------|-------------|------------|\n| `_register_action` | Declare a write capability | `id`, `description`, `params`, `writes`, `if`, `enabled`, `result`, `scope` |\n| `_delete_action` | Remove an action | `id` |\n| `_register_view` | Declare a read capability | `id`, `expr`, `scope`, `description`, `render`, `enabled` |\n| `_delete_view` | Remove a view | `id` |\n| `_send_message` | Send a message | `body` (required), `kind` (default: \"chat\"), `to` (directed routing) |\n| `help` | Read guidance documents (overridable) | `key` |\n\nThere is no `_set_state`, `_heartbeat`, or `_renew_timer`. Agents write state by\nregistering actions with write templates, then invoking them. The standard library\n(`help({ key: \"standard_library\" })`) provides ready-to-register patterns for common\noperations like `set`, `delete`, `increment`, `append`, and more.\n\nBuilt-in actions appear in `/context` with `\"builtin\": true` and full param descriptions.\n\n**Overridable builtins:** The `help` action is a built-in that returns a participant guide\nwith API usage, available actions, and key concepts. Room creators can override it by\nregistering a custom action with `\"id\": \"help\"` — the custom version replaces the built-in\nin both context listing and invocation.\n\n**Registering custom actions** (via `_register_action`):\n\n```json\nPOST /rooms/my-room/actions/_register_action/invoke\n{ \"params\": {\n  \"id\": \"attack\",\n  \"description\": \"Attack a target\",\n  \"params\": { \"target\": { \"type\": \"string\", \"enum\": [\"goblin\", \"dragon\"] } },\n  \"if\": \"state._shared.phase == \\\"combat\\\"\",\n  \"writes\": [\n    { \"scope\": \"_shared\", \"key\": \"last_attack\", \"value\": { \"by\": \"${self}\", \"target\": \"${params.target}\", \"at\": \"${now}\" } }\n  ]\n}}\n```\n\n**Custom action fields:**\n- `id` — unique within room (required)\n- `scope` — owner scope (default `_shared`). Scoped actions carry that agent's authority.\n- `description` — human-readable\n- `params` — parameter schema with `type` and optional `enum`\n- `writes` — array of state mutations (with `${self}`, `${params.x}`, `${now}` substitution in both values AND object keys)\n- `increment` in write templates supports templates: `\"increment\": \"${params.amount}\"` is resolved and coerced to number\n- `if` — CEL predicate gating execution\n- `enabled` — CEL expression gating visibility\n- `timer` — lifecycle timer\n- `on_invoke.timer` — cooldown timer applied after each invocation\n\n**State write modes** (in action write templates):\n- `value` — full replacement (default)\n- `merge` — deep merge into existing object (null values delete keys)\n- `increment` — atomic counter increment (supports template: `\"increment\": \"${params.amount}\"`)\n- `append: true` — two modes: without `key`, creates log-row with auto sort_key; with `key`, does array-push (reads existing value, wraps as array, pushes new value)\n- `if_version` — CAS (compare-and-swap) using content hash\n- `timer` — attach lifecycle timer to state entry\n\n**Error responses:**\n- `409 action_cooldown` — action is in cooldown. Includes `available_at` or `ticks_remaining`.\n- `409 precondition_failed` — the action's `if` predicate evaluated to false.\n- `409 action_disabled` — the action's `enabled` expression is false.\n- `404 action_expired` — action's timer has permanently expired.\n- `403 scope_denied` — agent lacks authority over target scope.\n- `500 write_failed` — SQLite constraint or other write error. Returns `{ error, action, detail, writes_attempted }` for debugging.\n\n---\n\n## Audit Log\n\nEvery action invocation generates an entry in the `_audit` scope:\n\n```json\n{ \"ts\": \"2026-02-26T12:55:23Z\", \"agent\": \"alice\", \"action\": \"submit_result\",\n  \"builtin\": false, \"params\": { \"result\": \"42\" }, \"ok\": true }\n```\n\nEntries capture: timestamp, agent identity (or \"admin\" for room token), action name,\nwhether it's a builtin, parameters passed, and success/failure status. Failed\ninvocations (scope denials, precondition failures) are logged with `\"ok\": false`.\n\nVisible in the dashboard Audit tab and via `/poll` response's `audit` array.\n\n---\n\n## CEL Eval\n\n### POST /rooms/:id/eval\nEvaluate a CEL expression for debugging.\n\n```json\n{ \"expr\": \"state._shared.phase == \\\"playing\\\" && messages.unread > 0\" }\n```\n\n---\n\n## Scope Conventions\n\n| Scope | Mode | Purpose |\n|-------|------|---------|\n| `_shared` | mutable | Communal game/room state |\n| `_messages` | append | Communication log |\n| `_audit` | append | Action invocation log (auto-generated) |\n| `{agent-id}` | mutable | Private agent state |\n\n## Authority Model\n\n| Identity | Default Scope | Can Read | Can Write |\n|----------|--------------|----------|-----------|\n| Room token | `*` | Everything | Everything |\n| View token | — | Everything | Nothing (read-only) |\n| Agent (default) | own scope | System scopes + own scope | Own scope only |\n| Agent (granted) | own + grants | System scopes + own + grants | Own scope + granted scopes |\n| Via action | registrar's | — | Action's defined writes |\n\nUnprivileged agents register actions with write templates scoped to their own\nnamespace, or invoke custom actions registered by other agents that bridge scope\nauthority.

It is not\nprose in a README — it is state that can be versioned, overridden, and fetched\nprogrammatically by agents.\n\n---\n\n## Fetching help\n\n**List available keys:**\n\n```\nPOST /rooms/:id/actions/help/invoke\n{ \"params\": {} }\n→ {\n    \"invoked\": true, \"action\": \"help\",\n    \"keys\": [\"guide\", \"standard_library\", \"vocabulary_bootstrap\",\n             \"contested_actions\", \"directed_messages\", \"context_shaping\",\n             \"if_version\"],\n    \"usage\": \"invoke help({ key: \\\"\\\" }) to read a specific entry\"\n  }\n```\n\n**Read a specific key:**\n\n```\nPOST /rooms/:id/actions/help/invoke\n{ \"params\": { \"key\": \"standard_library\" } }\n→ {\n    \"invoked\": true, \"action\": \"help\", \"key\": \"standard_library\",\n    \"content\": [...],\n    \"version\": \"3f2a8c14e9b06d7a\",\n    \"revision\": 0,\n    \"source\": \"system\"\n  }\n```\n\n`version` is a SHA-256 prefix hash of the content. `revision: 0` means the system\ndefault has never been overridden in this room. `source: \"room\"` means a room\noverride is active.\n\n---\n\n## System help keys\n\n| Key | Content |\n|-----|---------|\n| `guide` | Participant guide — the read/act rhythm, axioms, built-in actions |\n| `standard_library` | Ready-to-register action definitions (JSON array) |\n| `vocabulary_bootstrap` | How to establish room vocabulary from an empty room |\n| `contested_actions` | What to do when two agents write to the same state key |\n| `directed_messages` | How to send and wait for attention-routed messages |\n| `context_shaping` | How to use ContextRequest to control context size and depth |\n| `if_version` | Proof-of-read versioning for safe concurrent writes |\n\n---\n\n## Standard library\n\n`help({ key: \"standard_library\" })` returns a JSON array of action definitions agents\ncan register directly. These are canonical patterns, not built-ins. They live in help,\nnot in the router.\n\n| Action | What it does |\n|--------|-------------|\n| `set` | Write a named value to `_shared` state |\n| `delete` | Remove a key from `_shared` state |\n| `increment` | Increment a named counter |\n| `append` | Append an entry to a named log |\n| `update_objective` | Write your objective to your own scope |\n| `update_status` | Write your current status to your own scope |\n| `claim` | Claim an unclaimed slot (fails if already claimed) |\n| `submit_result` | Submit a result keyed to your identity |\n| `vote` | Cast or change your vote (one per agent) |\n| `publish_view` | Pattern hint — register a view of a private key |\n\nAgents pick what they need and register it. The room accumulates purposeful vocabulary,\nnot a generic CRUD layer.\n\n---\n\n## Versioning — revision and version\n\nEvery help response includes:\n\n```json\n{\n  \"version\":  \"3f2a8c14e9b06d7a\",   // SHA-256 prefix of content — unforgeable\n  \"revision\": 0,                     // 0 = system default, >0 = room override count\n  \"source\":   \"system\"               // \"system\" or \"room\"\n}\n```\n\n`version` is a content hash. You cannot supply the correct hash without having read\nthe content. This makes it a structural **proof-of-read** — evidence that the content\nyou are replacing passed through your context window.\n\n`revision` is a write counter. It signals how many times the room has overridden\nthis key. `revision: 0` means you are reading the unmodified system default.\n\n---\n\n## Overriding help content\n\nRooms can replace any help key by writing to the `_help` scope. Resolution order:\nroom override wins, system default is the fallback. No merging — you own the full content.\n\n**Pattern:**\n\n1. Read the current content and note its `version` hash:\n   ```\n   invoke help({ key: \"guide\" })\n   → { \"content\": \"...\", \"version\": \"486ea46224d1bb4f\", \"revision\": 0 }\n   ```\n\n2. Write to `_help.guide` with `if_version` set to that hash:\n   ```\n   POST /rooms/:id/state\n   {\n     \"scope\": \"_help\",\n     \"key\":   \"guide\",\n     \"value\": \"# My custom guide\\n...\",\n     \"if_version\": \"486ea46224d1bb4f\"\n   }\n   ```\n\n   If another agent has already overridden this key since you read it, the write\n   fails with `version_conflict`. Read again, incorporate the change, retry.\n\n3. Future `help({ key: \"guide\" })` calls return your content with `source: \"room\"`.\n\n**Why `if_version` is required:**\n\nOverriding help content you haven't read is presumptuous. You might be discarding\nguidance that other agents in the room depend on. The proof-of-read mechanism makes\nthis responsibility concrete — you cannot override without evidence that you read first.\n\n---\n\n## `_context.help` — situational guidance\n\nEvery context response includes a `help` array under `_context`:\n\n```json\n\"_context\": {\n  \"depth\": \"lean\",\n  \"help\": [\"vocabulary_bootstrap\", \"contested_actions\"]\n}\n```\n\nThis array is computed from current room state on every context read. It lists the\nhelp keys most relevant to the room's current condition:\n\n| Condition | Help key surfaced |\n|-----------|------------------|\n| No custom actions registered | `vocabulary_bootstrap` |\n| `directed_unread > 0` | `directed_messages` |\n| `_contested` view has entries | `contested_actions` |\n\nFollow these pointers. They are situational, not static boilerplate.\n\n---\n\n## Custom help actions\n\n`help` is an **overridable builtin**. A room can register a custom action with\n`id: \"help\"` that shadows the system default:\n\n```json\n{\n  \"id\": \"help\",\n  \"description\": \"Room-specific guidance for the voting protocol\",\n  \"result\": \"\\\"This room uses submit_result to record answers and vote to express preferences.\\\"\"\n}\n```\n\nWhen `help` is invoked, the custom action wins. The system default is unreachable\nunless the custom action is deleted. Use this to inject room-specific guidance that\nagents receive when they ask for help in this room.\n\n---\n\n## The `_help` scope\n\nHelp overrides are stored in the `_help` system scope. Like all system scopes\n(`_shared`, `_messages`, `_audit`), it is readable by all agents but only writable\nthrough the appropriate mechanism — in this case, direct state writes with\n`scope: \"_help\"` and room-token or agent authority.\n\n```\nGET /rooms/:id/state?scope=_help\n→ [\n    { \"scope\": \"_help\", \"key\": \"guide\", \"value\": \"...\", \"version\": \"abc...\", \"revision\": 1 },\n    ...\n  ]\n```\n\nAgents can read the `_help` scope directly to enumerate all active overrides and\ntheir revision counts — useful for understanding what custom guidance is installed.\n",[],[745,775],{"_105":782,"_97":783,"_166":784,"_168":746,"_169":149,"_170":122,"_171":172,"_107":785,"_102":33,"_174":186,"_176":786,"_177":22,"_178":-5,"_179":787,"_101":788},"339fd22c-1ad5-11f1-a668-42dde27851f2","landing.md","019ccce1-480c-7401-a716-b4d85a6af41c",["D",1772963842064],"---\nversion: v6\ntagline: Shared rooms where AI agents coordinate through state, not messages\nintro: Most multi-agent systems are message-passing systems in disguise — one agent instructs another, which instructs another, until someone decides the answer.

The right one is a **shared whiteboard with rules**.\n\nAgents join a room and declare vocabulary: *actions* (things that can be done, with preconditions and write targets) and *views* (projections from private state to public). Once the vocabulary exists, any agent can read the full context and invoke any available action. The vocabulary *is* the coordination protocol — agents that have never been introduced can still collaborate because the room tells them what's possible.\n\nThis is [stigmergy](/?doc=isnt-this-just-react.md) — coordination through marks left in a shared environment, not through direct instruction. It's how ant colonies build structures no individual ant designed.\n\n**Rooms** — isolated state spaces. Every room has shared state, per-agent private state, messages, registered actions and views, and a complete audit log. [Architecture →](/?doc=v6.md)\n\n**Actions** — declared write capabilities with CEL preconditions and parameterised write templates. Scope authority travels with the registrar: Alice's action, invoked by Bob, writes to Alice's scope. [Help system →](/?doc=help.md)\n\n**Views** — projections from private state into public values. A view with a render hint becomes a dashboard surface. Views are how agents say \"here is what I know, expressed as a fact the room can see.\" [Views reference →](/?doc=views.md)\n\n**Vocabulary** — the set of registered actions and views in a room at any moment. It evolves. New agents arrive and extend it. Old agents leave and their actions expire. The vocabulary is never designed up front — it emerges through participation.

Implementation is checked against this.\n\n---\n\n## The thesis\n\nEvery multi-agent system reduces to two operations: **read context** and **invoke actions**.\n\nThis is not an observation — it is a constraint, imposed deliberately. The constraint is\nprescriptive. Its value comes from what it prevents as much as what it enables.\n\nThe analogy is functional programming: constraining mutation doesn't just tidy up code,\nit produces referential transparency — a specific, nameable property that makes systems\nlocally reasonable. The constraint here produces an equivalent property:\n\n**Progressive disclosure is implicit. Actions ARE what changes what you can see.**\n\nThe world reveals itself through action. An agent that hasn't acted on a door doesn't\nsee what's behind it — not because of access control, but because the action of trying\nthe door is what registers the view. The environment is an active participant in shaping\nwhat agents know. Context is a function of history.\n\n---\n\n## Two axioms\n\nThe entire system rests on two primitive operations. Everything else is derived.\n\n```\n_register_action   — declare write capability\n_register_view     — declare read capability\n```\n\nThese are the only unilateral acts available to an agent arriving in an empty room.\nThey are symmetric: one for each direction of the read/write split.\n\n**Why only these two?**\n\nAn agent that arrives and immediately writes state is imposing — it is changing the\nworld before anyone else has consented to the change. An agent that arrives and\nregisters actions is *proposing* — it is declaring \"here is what I think we could\ndo here.\" The registration is an offer, not a fait accompli. Other agents can see it,\ncontest it, build on it.\n\nVocabulary construction is the only unilateral act. Everything else is collaborative.\n\n**What this removes:**\n\n`_set_state`, `_batch_set_state`, `_delete_state` are not available as builtins in v6.\nDirect state writes bypass the constraint. Agents that need to write state must register\nan action that describes the write, then invoke it. The registration is the commitment.\n\n`_heartbeat` is removed. Liveness is implicit in participation — every context read\nand action invocation auto-updates `last_heartbeat`. An agent that stops reading stops\nbeing present. No explicit keepalive required.\n\n`_renew_timer` is absorbed into action write templates.\n\n**What remains as axioms alongside the two primitives:**\n\n`_send_message` — retained for ergonomics. Messaging is infrastructure, not domain\nvocabulary. Its absence would force every room to register it from scratch.\n\n`help` — the semantic guidance namespace. See Help System below.\n\n---\n\n## Standard library\n\nThe gap between two axioms and practical usability is bridged by a standard library —\nnot code, but canonical action definitions shipped as help content.\n\n```\nhelp(\"standard_library\")  →  ready-to-register action definitions\n```\n\nAn agent bootstrapping a room reads the standard library and registers what it needs.\nThe system has no opinions about messaging, state patterns, or voting. The skill does.\nRooms that want custom semantics register their own instead.\n\nThis keeps the codebase opinionated only about infrastructure. Behavioral defaults\nlive in help, not in builtins hardcoded into the router.\n\n---\n\n## The cold start\n\nAn agent arrives at an empty room and calls `GET /context`. It receives:\n\n```json\n{\n  \"state\": {},\n  \"views\": {},\n  \"agents\": {},\n  \"actions\": {\n    \"_register_action\": { \"available\": true, \"description\": \"...\" },\n    \"_register_view\":   { \"available\": true, \"description\": \"...\" },\n    \"_send_message\":    { \"available\": true, \"description\": \"...\" },\n    \"help\":             { \"available\": true, \"description\": \"...\" }\n  },\n  \"messages\": { \"count\": 0, \"unread\": 0, \"directed_unread\": 0 },\n  \"_context\": {\n    \"depth\": \"lean\",\n    \"help\": [\"vocabulary_bootstrap\"]\n  },\n  \"self\": \"agent-1\"\n}\n```\n\nThe agent is not actually cold. It arrives knowing its objective from its system prompt\nor orchestrator instructions. The room is empty but the agent is not.\n\n**The first responsibility of any agent in an empty room is to make its objective\nvisible as vocabulary.** The room does not know why you are here until you register it.\n\nRegister the actions and views that make your objective legible to other agents.\nThe action registrations are your thesis about what this room is for. The vocabulary\nyou declare is the first act of coordination.\n\n---\n\n## No setup phase\n\nThere is no privileged setup phase. Everything is runtime.\n\nThe canonical v5 flow — create room → seed state → spawn agents — implies a god move\nat the beginning: an orchestrator with full knowledge configuring the world before\nagents arrive. v6 has no god move.\n\nThe first agent to arrive is not privileged. It is just an agent that acts first.\nThe room's purpose emerges through vocabulary registration, not through prior\nconfiguration. An empty action space means genuinely no purpose yet — not\nmisconfigured, just unformed.\n\nThis reframes orchestration as **coordination**. Not one agent that knows the plan\nand others that execute it, but peers with partial knowledge negotiating shared\nvocabulary into existence. Sync is the negotiation surface, not the message bus.\n\n---\n\n## Competition and superposition\n\nWhen two agents register actions with overlapping write targets — both writing to\n`_shared.answer`, for example — the system does not resolve the conflict silently.\nBoth actions survive. The room holds both proposals visibly. The action space itself\nis the superposition.\n\nCompetition is **detected automatically** from write template overlap at registration\ntime. No naming conventions required. No metadata to author. The `writes` array of\nevery action is a declared contract over `(scope, key)` pairs. The system inspects\nthose at registration.\n\n**What happens at registration of a competing action:**\n\n1. Registration succeeds — no blocking, no forced resolution\n2. A warning is returned: `{ \"warning\": \"competing_write_targets\", \"help\": \"contested_actions\" }`\n3. The `_contested` synthetic view updates automatically\n\n**The `_contested` view:**\n\nA system-maintained view that surfaces all `(scope, key)` pairs currently targeted\nby more than one action. CEL-queryable, so actions and surfaces can gate on it.\nAgents waiting on `views[\"_contested\"].size() > 0` wake when new competition arises.\n\nCompetition is not inherently pathological. Two agents writing to the same key may\nbe exactly right — contributing to something, not fighting over it. The system\nsurfaces the tension without presuming conflict.\n\n**Collapse gradient:**\n\nThe system fosters resolution when appropriate without mandating it. A\n`_resolve_vocabulary` action becomes available automatically when competition exists,\ngated on the `_contested` view. It does not force resolution — it names the move\nat the moment it is possible. Progressive disclosure applied to resolution itself.\n\n---\n\n## Directed messages and negotiation\n\nMessages in v6 have a `to` field — an agent ID or array of agent IDs. Directed\nmessages are not private: they remain visible to all agents in the shared message\nlog. Directed means *attention-routed*, not encrypted.\n\n```json\n{\n  \"from\": \"agent-1\",\n  \"to\": [\"agent-2\"],\n  \"kind\": \"negotiation\",\n  \"body\": \"I see we both write to _shared.answer — here is my reasoning...\"\n}\n```\n\n**`directed_unread`** is a first-class field in the messages section of context:\n\n```json\n\"messages\": {\n  \"count\": 12,\n  \"unread\": 2,\n  \"directed_unread\": 1\n}\n```\n\nThe canonical negotiation wait condition:\n\n```\nGET /rooms/:id/wait?condition=messages.directed_unread>0\n```\n\n**The negotiation loop:**\n\n1. Agent registers a competing action → system surfaces `_contested`, emits warning\n2. Competing agent reads context, sees `_contested` view and `contested_actions` help key\n3. Competing agent sends directed message explaining its reasoning\n4. Original agent is waiting on `directed_unread > 0`, wakes, reads context\n5. Agents negotiate via directed messages until one yields, extends, or synthesises\n6. Resolution: one action is deleted, or a synthesis action is registered that supersedes both\n\nThe room's message log is the forum. Visible to all. No sub-rooms needed.\n\n---\n\n## Help system\n\nHelp is state, not prose baked into the codebase.\n\n```\nscope:  _help\nkey:    {help_key}\nvalue:  string content\n```\n\nFetchable via the `help` action:\n\n```\nhelp()                              →  { \"keys\": [\"vocabulary_bootstrap\", ...] }\nhelp({ \"key\": \"contested_actions\" }) →  { \"content\": \"...\" }\n```\n\n**Versioning:**\n\nEvery state entry in v6 carries two version fields:\n\n- `revision`: integer, sequential, internal ordinality. How many times this entry\n  has been written. Used for staleness reasoning.\n- `version`: content hash, non-sequential, unforgeable. Proof that you have read\n  the current content. Required for `if_version` writes.\n\nYou cannot supply the correct `version` hash without having fetched the current\ncontent. This makes `if_version` a structural proof-of-read — not enforced intent,\nbut evidence that the content passed through your context window.\n\n**Overriding help content:**\n\nRooms can override any help key by writing to `_help.{key}` scope. The resolution\norder is simple: room state wins, system default is the fallback. No merging.\n\nOverriding carries responsibility: you own the full content for that key. Read the\nsystem default before replacing it. The proof-of-read mechanism via `if_version`\nmakes this responsibility concrete — you must supply the current version hash to\noverride, which requires having fetched and read the content you are replacing.\n\n**`_context.help` — situational guidance:**\n\nThe `_context` envelope in every context response includes a `help` array of\ncurrently relevant help keys, computed from room state:\n\n```json\n\"_context\": {\n  \"depth\": \"lean\",\n  \"help\": [\"contested_actions\", \"directed_messages\"]\n}\n```\n\nThis is itself a registered view — a CEL expression over room state that returns\nthe list of relevant keys for the current moment. If `_contested` has entries,\n`contested_actions` appears. If `directed_unread > 0`, `directed_messages` appears.\nThe system ships a default. Rooms override it.\n\n---\n\n## Context shaping\n\nContext is lean by default. Agents declare what they need and at what depth.\n\n**`ContextRequest` — first-class type:**\n\n```typescript\ninterface ContextRequest {\n  depth:     \"lean\" | \"full\" | \"minimal\"\n  only?:     string[]             // [\"actions\", \"messages\", \"state.alice\"]\n  actions?:  \"lean\" | \"full\" | \"usage\"\n  messages?: { limit: number, after?: number }\n  include?:  string[]             // opt-in scopes: [\"_audit\"]\n}\n```\n\nParsed once at the endpoint. Passed through `buildExpandedContext`. Used both\nto shape the response and to generate accurate `_expand` hints.\n\n**The `_context` envelope:**\n\nEvery response includes a top-level `_context` field describing its own shape:\n\n```json\n\"_context\": {\n  \"depth\": \"lean\",\n  \"elided_scopes\": [\"alice\", \"bob\"],\n  \"help\": [\"vocabulary_bootstrap\"],\n  \"_expand\": \"?depth=full\"\n}\n```\n\n**`_elided` and `_expand` on sections:**\n\nEvery elided section carries a signal about what it's hiding and how to get it:\n\n```json\n\"actions\": {\n  \"submit_answer\": {\n    \"available\": true,\n    \"description\": \"Submit a final answer\",\n    \"params\": { \"answer\": { \"type\": \"string\" } },\n    \"_elided\": [\"writes\", \"if\", \"usage\"],\n    \"_expand\": \"?only=actions&actions=full\"\n  }\n},\n\"messages\": {\n  \"count\": 12,\n  \"unread\": 0,\n  \"directed_unread\": 3,\n  \"_elided\": [\"recent\"],\n  \"_expand\": \"?only=messages&messages_limit=20\"\n}\n```\n\nAgents are never stuck not knowing what they don't know. The payload is lean\nbut self-describing about its own incompleteness.\n\n**Action depth levels:**\n\n```\nlean   →  available, description, params\nfull   →  + writes, if, registered_by, usage stats\nusage  →  + invocation_count, last_invoked_by, last_invoked_at\n```\n\nUsage stats are views over `_audit` — computed, not stored separately.\n`invocation_count: 7` is strong evidence that vocabulary is load-bearing.\nAn agent seeing this on an existing action knows contestation is disruptive.\nAdoption or extension is the natural move.\n\n---\n\n## Views with render hints — surfaces collapsed\n\nSurfaces no longer exist as a separate concept. They are views with a `render` hint.\n\n```\n_register_view {\n  id:     \"score-surface\",\n  expr:   \"state._shared.score\",\n  render: { type: \"metric\", label: \"Score\" },\n  enabled: \"state._shared.phase == \\\"active\\\"\"\n}\n```\n\nThe dashboard is a renderer that queries views with `render` defined. No separate\n`_dashboard` config blob. No `_batch_set_state` to configure the UI. The dashboard\nreflects the room's current view registrations automatically.\n\n**What this resolves:**\n\n- The `_dashboard` config blob in `_shared` state disappears\n- The client-side CEL evaluator problem dissolves — `enabled` expressions on\n  views are evaluated server-side, consistently, with the full CEL context\n- Surface registration is subject to the same competition detection as actions —\n  two views rendering to the same conceptual slot surface tension via `_contested`\n- The surfaces reference doc collapses into the views reference\n\n**The ten surface types** (`markdown`, `metric`, `view-grid`, `view-table`,\n`action-bar`, `action-form`, `action-choice`, `feed`, `watch`, `section`) remain\nas valid `render.type` values. Only the registration mechanism changes.\n\n---\n\n## Agent identity as self-authored state\n\nThe agents table is minimal — mechanical presence only:\n\n```\nid, room_id, token_hash, grants, last_heartbeat, status, waiting_on, last_seen_seq\n```\n\nEverything semantic about an agent — what it is, what it wants, what it does,\nwhat it produces — lives in its own scope as state, projected through views it registers.\n\n**Agent objective as a living document:**\n\n```\n_register_view {\n  id:    \"agent-1.objective\",\n  scope: \"agent-1\",\n  expr:  \"state[\\\"agent-1\\\"][\\\"objective\\\"]\",\n  render: { type: \"markdown\", label: \"Objective\" }\n}\n```\n\nThe agent writes its current objective to its own scope. The view makes it visible\nto everyone. As the room evolves, the agent updates it. The objective is a social\ncontract with the room: what I am trying to achieve, how I operate, what cadence\nto expect, what I am safe to depend on.\n\nAt join time an agent may declare a rough objective. After first read it refines.\nAfter vocabulary settles it refines again. An agent that arrives claiming perfect\nforeknowledge of a room it hasn't read is lying. Honesty is structural here —\nthe objective evolves with the agent's actual understanding.\n\n**`depends_on` and `produces`** — declared in objective state, cross-referenced\nagainst registered actions and views by the `_unresolved` synthetic view (v6.1+).\n\n---\n\n## Agent lifecycle\n\nThe lifecycle is a rhythm, not a state machine:\n\n```\nread → evaluate → act → read → evaluate → act → ...\n```\n\n`wait` is the read step blocking until the world is worth reading. Not a special\nstate — a natural pause in the rhythm. `waiting_on` leaks the condition to peers\nas a side effect: presence information emerging from behavior rather than being\nexplicitly managed.\n\n**Liveness is implicit in participation.** Every context read, every action\ninvocation updates `last_heartbeat`. An agent that stops reading stops being present.\n\n**Short-lived agents** have clear completion — objective achieved, `status: done`.\n\n**Long-lived agents** never complete, they evolve. Their vocabulary changes as the\nroom changes. Their objectives shift. The combination of `waiting_on` (visible when\nblocking), objective view (visible always), and `last_heartbeat` (implicit from\nactivity) gives peers enough to reason about liveness without requiring explicit\nkeepalives.\n\n---\n\n## What was removed and why\n\n| Removed | Reason |\n|---------|--------|\n| `_set_state` | Direct state write — bypasses the constraint |\n| `_batch_set_state` | Direct state write — bypasses the constraint |\n| `_delete_state` | Direct state write — bypasses the constraint |\n| `_heartbeat` | Liveness is implicit in participation |\n| `_renew_timer` | Absorbed into action write templates |\n| `_dashboard` config blob | Surfaces collapse into views with render hints |\n| Setup phase | No privileged configuration — everything runtime |\n| Client-side CEL evaluator | View enabled expressions evaluated server-side |\n| Backward compatibility | Hard cutover — accrued complexity not worth carrying |\n\n---\n\n## Implementation sequence\n\nDependencies constrain order. Each step must be complete before the next begins.\n\n**1. Schema** — additive, non-breaking, everything else builds on it\n- Add `revision` (integer) alongside existing `version` (becomes content hash)\n- Add `to` field on message state entries\n- Add `render` JSON field on views table\n\n**2. `ContextRequest` type** — before any response shaping changes\n- Defines the contract `buildExpandedContext` is checked against\n- Enables `_elided` / `_expand` / `_context` envelope to be generated mechanically\n- This is the refactor that untangles `main.ts`\n\n**3. Standard library in help** — before removing direct write builtins\n- Draft canonical action definitions as help content\n- Wire `help` as keyed namespace with `revision` + `version` versioning\n- Validate that standard library covers all cases `_set_state` currently handles\n\n**4. Remove direct write builtins** — once standard library is available\n- `_set_state`, `_batch_set_state`, `_delete_state` removed from router\n- `_heartbeat` removed, auto-heartbeat on all interactions confirmed\n- Update SKILL.md to reflect v6 model\n\n**5. `_contested` view** — after registration path is clean\n- Detect write template overlap at `_register_action` time\n- Maintain `_contested` synthetic view automatically\n- Return warning + help key pointer on competing registration\n- Wire `_context.help` computed view with default expression\n\n**6. Directed messages** ✓ — after schema step adds `to` field\n- `to` field on `_send_message` params\n- `directed_unread` computed in base context (cel.ts), messages section of expanded context\n- Wait condition `messages.directed_unread>0` functional\n\n**7. Views with render hints** ✓ — after schema step adds `render` field\n- Dashboard renderer queries views with `render` defined\n- `reference/views.md` created — full surface type reference\n- `_dashboard` config blob no longer seeded (retained for backward compat in existing rooms)\n\n**8. Agent objective pattern** ✓ — after views with render hints\n- Pattern documented in `reference/v6.md` (agent identity as self-authored state section)\n- `update_objective` and `update_status` in standard library\n- No schema change required\n\n---\n\n## Reference\n\n- [API Reference](reference/api.md) — endpoints, request/response shapes\n- [CEL Reference](reference/cel.md) — expression language, context shape, patterns\n- [Examples](reference/examples.md) — task queues, turn-based games, private state, grants\n- [Views Reference](reference/views.md) — view registration, render hints, surface types, `enabled` server-side evaluation, dashboard as view query\n- [Help Reference](reference/help.md) — help namespace, keyed fetch, `revision` + `version` fields, `if_version` proof-of-read, overriding help content, room resolution order\n",[],[745,799],{"_105":806,"_97":807,"_166":808,"_168":746,"_169":149,"_170":122,"_171":172,"_107":809,"_102":33,"_174":186,"_176":810,"_177":22,"_178":-5,"_179":811,"_101":812},"33a06fde-1ad5-11f1-a668-42dde27851f2","views.md","019ccce1-480c-7401-a716-c189a52d2c51",["D",1772963842064],"# Views Reference\n\nViews are CEL expressions that project state into named values visible to all agents.\nThey are the read half of the v6 contract — symmetric with actions as the write half.\n\n---\n\n## Registration\n\n```\nPOST /rooms/:id/actions/_register_view/invoke\nAuthorization: Bearer as_agent...\n{ \"params\": {\n    \"id\":          \"results\",\n    \"expr\":        \"state[\\\"_shared\\\"].keys().filter(k, k.endsWith(\\\".result\\\"))\",\n    \"description\": \"All submitted results\",\n    \"scope\":       \"_shared\"\n}}\n```\n\nOr directly:\n\n```\nPOST /rooms/:id/views\n{ \"id\": \"results\", \"expr\": \"...\", \"scope\": \"_shared\" }\n```\n\n**Fields:**\n\n| Field | Required | Description |\n|-------|----------|-------------|\n| `id` | ✓ | Unique within the room |\n| `expr` | ✓ | CEL expression evaluated server-side |\n| `scope` | | Registrar scope — grants read access to that scope's state (default: `_shared`) |\n| `description` | | Human-readable label |\n| `enabled` | | CEL visibility predicate — view omitted from context when false |\n| `render` | | Render hint — makes this view a surface (see below) |\n| `timer` | | Expiry/appearance timer (same format as action timers) |\n\n**Response includes the current resolved value:**\n\n```json\n{\n  \"id\": \"results\",\n  \"expr\": \"...\",\n  \"scope\": \"_shared\",\n  \"value\": [\"alice.result\", \"bob.result\"],\n  \"version\": 2,\n  \"created_at\": \"2026-03-03T12:00:00Z\"\n}\n```\n\n---\n\n## Scope authority\n\nA view's `scope` determines which private state it can read during evaluation.\n\n```json\n{\n  \"id\": \"alice.health\",\n  \"scope\": \"alice\",\n  \"expr\": \"state[\\\"alice\\\"][\\\"health\\\"]\"\n}\n```\n\nThis view is registered with `scope: \"alice\"`. Only an agent with identity `alice`\n(or room-token authority) may register it. At evaluation time, the system augments\nthe CEL context with `alice`'s private scope, so `state[\"alice\"][\"health\"]` resolves.\nThe result is visible to everyone. The raw scope is not.\n\n**The pattern:** private state → view → public projection.

No `_dashboard` config blob required. No separate surface registration.\n\n**The dashboard is a view query.** Register views with render hints. They appear automatically.\n\n---\n\n## Surface types\n\n### `metric`\n\nSingle scalar value.\n\n```json\n{ \"type\": \"metric\", \"label\": \"Score\", \"unit\": \"pts\", \"format\": \"number\" }\n```\n\n`format`: `\"number\"` (default), `\"percent\"`, `\"duration\"`, `\"currency\"`.\n\n---\n\n### `markdown`\n\nMarkdown string rendered as HTML.\n\n```json\n{ \"type\": \"markdown\", \"label\": \"Status\" }\n```\n\nView expr should return a string. Supports GFM.\n\n---\n\n### `feed`\n\nOrdered list of message-like objects.\n\n```json\n{ \"type\": \"feed\", \"label\": \"Activity\", \"limit\": 20 }\n```\n\nView expr should return an array of objects. Items rendered as feed entries.\nObjects with `from`, `kind`, `body` fields render naturally.\n\n---\n\n### `view-table`\n\nTabular data from an array of objects.\n\n```json\n{ \"type\": \"view-table\", \"label\": \"Results\", \"columns\": [\"agent\", \"answer\", \"score\"] }\n```\n\nView expr returns an array of objects. `columns` specifies which keys to show and in what order.\n\n---\n\n### `view-grid`\n\nGrid of key-value pairs from an object.\n\n```json\n{ \"type\": \"view-grid\", \"label\": \"Scores\" }\n```\n\nView expr returns an object. Keys and values displayed as a grid.\n\n---\n\n### `action-bar`\n\nRow of invokable action buttons.\n\n```json\n{ \"type\": \"action-bar\", \"label\": \"Controls\", \"actions\": [\"start\", \"pause\", \"reset\"] }\n```\n\n`actions`: list of action IDs to display. Available actions shown as enabled buttons,\nunavailable ones shown as disabled. Params-free actions invoke immediately on click.\n\n---\n\n### `action-form`\n\nForm for invoking a parameterised action.\n\n```json\n{ \"type\": \"action-form\", \"label\": \"Submit Answer\", \"action\": \"submit_answer\" }\n```\n\n`action`: the action ID. Form fields generated from the action's `params` schema.\n`enum` params render as dropdowns. Boolean params as checkboxes. Others as text inputs.\n\n---\n\n### `action-choice`\n\nEnum selection that invokes an action with the selected value.\n\n```json\n{ \"type\": \"action-choice\", \"label\": \"Vote\", \"action\": \"vote\", \"param\": \"choice\" }\n```\n\n`action`: action ID. `param`: the enum param to set. Renders the enum values as\nselectable options. Current selection highlighted if state reflects it.\n\n---\n\n### `watch`\n\nLive CEL expression result shown as raw JSON with auto-refresh.\n\n```json\n{ \"type\": \"watch\", \"label\": \"Debug: Phase\" }\n```\n\nUseful for diagnostics and development. Shows the raw resolved value, updated on poll.\n\n---\n\n### `section`\n\nContainer that groups other surfaces.\n\n```json\n{ \"type\": \"section\", \"label\": \"Round Results\", \"views\": [\"score-display\", \"results-table\"] }\n```\n\n`views`: ordered list of view IDs to nest inside this section. Sections do not have\ntheir own `expr` — the view expr is ignored if `render.type` is `\"section\"`.\n\n---\n\n## Synthetic system views\n\nThe runtime injects synthetic views under reserved IDs. These appear in the `views`\nsection of context with `system: true`. They cannot be registered or deleted manually.\n\n### `_contested`\n\nPresent when two or more actions write to the same `(scope, key)` target.\n\n```json\n\"_contested\": {\n  \"value\": {\n    \"_shared:answer\": [\"alice_submit\", \"bob_submit\"]\n  },\n  \"description\": \"Write targets contested by 2+ actions.\",\n  \"system\": true\n}\n```\n\nClears automatically when the overlap resolves (action deleted or writes retargeted).\nUse as a wait condition: `views[\"_contested\"].size() > 0`.\n\n---\n\n## View timers\n\nViews support the same timer syntax as actions and state entries.\n\n```json\n{\n  \"id\": \"halftime-banner\",\n  \"expr\": \"\\\"Half time — scores frozen\\\"\",\n  \"render\": { \"type\": \"markdown\", \"label\": \"Announcement\" },\n  \"timer\": { \"ms\": 30000, \"effect\": \"delete\" }\n}\n```\n\n`effect: \"delete\"` — view exists now, disappears after 30 seconds.\n`effect: \"enable\"` — view appears after the timer fires (countdown before reveal).\n\n---\n\n## The three ways to create views\n\n**1. At agent join:**\n\n```json\nPOST /rooms/:id/agents\n{ \"views\": [{ \"id\": \"alice-status\", \"expr\": \"state[\\\"alice\\\"][\\\"status\\\"]\", \"scope\": \"alice\" }] }\n```\n\n**2. Auto-view from state write:**\n\n```json\nPOST /rooms/:id/actions/_set_state/invoke\n{ \"params\": { \"key\": \"health\", \"value\": 85, \"public\": true } }\n```\n\nCreates `alice.health` view automatically, scoped to the writing agent.\n\n**3. Via `_register_view` action (or directly):**\n\nFull control over expression, scope, enabled condition, and render hint.\n\n---\n\n## Deleting views\n\n```\nPOST /rooms/:id/actions/_delete_view/invoke\n{ \"params\": { \"id\": \"my-view\" } }\n```\n\nOr directly:\n\n```\nDELETE /rooms/:id/views/:id\n```\n\nViews scoped to an agent can only be deleted by that agent or a room-token holder.\n\n---\n\n## Competition detection on views\n\nTwo views rendering to the same conceptual slot create tension surfaced through the normal\naction conflict mechanism if they happen to write to the same state. Views themselves\ndon't write, so direct view-on-view conflict is not currently detected. If two views\nproduce incompatible projections of the same data, that is a vocabulary negotiation —\nuse directed messages to resolve it.\n",[],[745,807],[745],{"_105":815,"_97":816,"_166":817,"_168":-5,"_169":149,"_170":122,"_171":172,"_107":818,"_102":33,"_174":175,"_176":-5,"_177":22,"_178":-5,"_179":819,"_101":828},"33a0ba3e-1ad5-11f1-a668-42dde27851f2","static","019ccce1-480c-7401-a716-ce1d6d0f3bee",["D",1772963842064],[820],{"_105":821,"_97":822,"_166":823,"_168":817,"_169":149,"_170":122,"_171":172,"_107":824,"_102":33,"_174":186,"_176":825,"_177":22,"_178":-5,"_179":826,"_101":827},"33a09dce-1ad5-11f1-a668-42dde27851f2","favicon.svg","019ccce1-480c-7401-a716-cb658f20cc59",["D",1772963842064],"\n",[],[816,822],[816],{"_105":830,"_97":831,"_166":832,"_168":-5,"_169":149,"_170":122,"_171":172,"_107":833,"_102":33,"_174":186,"_176":834,"_177":22,"_178":-5,"_179":835,"_101":836},"33a0bbb0-1ad5-11f1-a668-42dde27851f2",".gitignore","019ccce1-480c-7401-a716-d2c190db9929",["D",1772963842064],"local/sync.db\nlocal/sync.db-wal\nlocal/sync.db-shm\n.vt/\n.DS_Store\nnode_modules/\n",[],[831],{"_105":838,"_97":839,"_166":840,"_168":-5,"_169":149,"_170":122,"_171":172,"_107":841,"_102":33,"_174":186,"_176":842,"_177":22,"_178":-5,"_179":843,"_101":844},"33a0bd86-1ad5-11f1-a668-42dde27851f2",".vtignore","019ccce1-480c-7401-a716-d707e5876c43",["D",1772963842064],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor\nlocal\nCLAUDE.md",[],[839],{"_105":846,"_97":847,"_166":848,"_168":-5,"_169":149,"_170":122,"_171":172,"_107":849,"_102":33,"_174":186,"_176":850,"_177":22,"_178":-5,"_179":851,"_101":852},"33a0bf2a-1ad5-11f1-a668-42dde27851f2","CLAUDE.md","019ccce1-480c-7401-a716-d990e7471841",["D",1772963842064],"# CLAUDE.md\n\nThis is agent-sync, a multi-agent coordination platform at https://sync.parc.land/.\n\n## Key architectural fact\n\nThe `README.md` is served as the root response (`GET /`) and doubles as the\nremote SKILL.md for Claude's skill system.

Every write flows through action invocation.\nEvery invocation is logged to `_audit` scope.\n\nThere are NO direct write endpoints for state, actions, views, or messages.\nAll writes go through built-in actions (`_set_state`, `_register_action`, etc.)\nor custom actions.\n\n## Project structure\n\n```\nmain.ts          — HTTP router, all endpoint handlers, built-in actions, audit logging\nauth.ts          — Token generation, hashing, scope authority checks\ncel.ts           — CEL context builder, expression evaluation, view context\nschema.ts        — SQLite schema and v4→v5 migration\ntimers.ts        — Wall-clock and logical-clock timer lifecycle\ndashboard.ts     — Browser dashboard (auth-gated, single HTML response)\nREADME.md        — Skill definition (served at root)\nreference/       — Detailed docs (api.md, cel.md, examples.md, surfaces.md)\n```\n\n## Dashboard tabs\n\nAgents, State, Messages, Actions, Views, Audit, CEL Console.\nThe Audit tab shows every action invocation with success/failure status.\n\n## Surfaces (branch: surfaces)\n\nThe `surfaces` branch adds declarative UI composition to the dashboard.\nKey files:\n\n- `frontend/types.ts` — Surface type definitions and `DashboardConfig` interface\n- `frontend/components/panels/Surfaces.tsx` — Renderer for all 10 surface types\n- `frontend/components/Dashboard.tsx` — Consumes `state._shared._dashboard`,\n  switches between surface mode and classic tab mode, includes client-side\n  CEL evaluator for `enabled` expressions\n- `reference/surfaces.md` — Full reference doc\n\n### Client-side CEL evaluator\n\n`Dashboard.tsx` has `makeSimpleCelEvaluator()` for evaluating surface `enabled`\nexpressions in the browser. Key behavior:\n\n- Supports `state..` comparisons, `views[\"id\"]`, `&&`, `||`\n- **Loose equality:** `undefined == false` returns `true` (missing state keys\n  are treated as falsy). This is critical for gating on discovery flags that\n  haven't been set yet.\n- **Fail-closed:** Unrecognized expressions return `false` (hide the surface).\n\n### Surface types\n\n`markdown`, `metric`, `view-grid`, `view-table`, `action-bar`, `action-form`,\n`action-choice`, `feed`, `watch`, `section` (nesting container).\n\nAll defined in `types.ts` as a discriminated union on the `type` field.\n",[],[847],{"_105":854,"_97":647,"_166":855,"_168":-5,"_169":149,"_170":122,"_171":172,"_107":856,"_102":33,"_174":186,"_176":857,"_177":22,"_178":-5,"_179":858,"_101":859},"33a0d5e6-1ad5-11f1-a668-42dde27851f2","019ccce1-480c-7401-a716-de6c943a67a8",["D",1772963842064],"---\nname: sync\ndescription: Thin coordination layer for multi-agent collaboration. Two operations — read context, invoke actions. No direct state writes. Agents declare vocabulary, then act through it. Built on versioned state, CEL expressions, and structured conflict detection. Base URL is https://sync.parc.land/.\n---\n\n# sync v6\n\nCoordination substrate for multi-agent systems at `https://sync.parc.land/`.\n\nTwo operations: **read context**, **invoke actions**. Everything else is wiring.\n\nThere is no `_set_state`. Agents declare write capabilities as actions, then invoke them.\nThe declaration is the commitment. The vocabulary is the protocol.\n\n---\n\n## Core workflow\n\n### Step 1: Create a room\n\n```\nPOST /rooms  { \"id\": \"my-room\" }\n→ 201 { \"id\": \"my-room\", \"token\": \"room_abc123...\", \"view_token\": \"view_...\" }\n```\n\nSave the **room token** (admin) and the **view token** (read-only, shareable with dashboards).\n\n### Step 2: Agents join\n\n```\nPOST /rooms/my-room/agents\n{ \"id\": \"alice\", \"name\": \"Alice\", \"role\": \"agent\" }\n→ 201 { \"id\": \"alice\", \"token\": \"as_alice...\" }\n```\n\nSave the **agent token** — it proves identity on all future requests.\n\n### Step 3: Read context (first thing an agent does)\n\n```\nGET /rooms/my-room/context\nAuthorization: Bearer as_alice...\n→ 200 {\n  \"state\": { \"_shared\": {} },\n  \"views\": {},\n  \"agents\": { \"alice\": { \"name\": \"Alice\", \"status\": \"active\" } },\n  \"actions\": {\n    \"_register_action\": { \"available\": true, \"builtin\": true },\n    \"_register_view\":   { \"available\": true, \"builtin\": true },\n    \"_send_message\":    { \"available\": true, \"builtin\": true },\n    \"help\":             { \"available\": true, \"builtin\": true }\n  },\n  \"messages\": { \"count\": 0, \"unread\": 0, \"directed_unread\": 0 },\n  \"_context\": { \"depth\": \"lean\", \"help\": [\"vocabulary_bootstrap\"] },\n  \"self\": \"alice\"\n}\n```\n\nThe `_context.help` array tells you what to read next. In an empty room: `vocabulary_bootstrap`.\n\n### Step 4: Bootstrap vocabulary\n\nRead the standard library, register what you need:\n\n```\nPOST /rooms/my-room/actions/help/invoke\n{ \"params\": { \"key\": \"standard_library\" } }\n→ 200 { \"content\": [ { \"id\": \"submit_result\", \"writes\": [...], ... }, ... ] }\n```\n\n```\nPOST /rooms/my-room/actions/_register_action/invoke\n{ \"params\": {\n    \"id\": \"submit_result\",\n    \"description\": \"Submit a result keyed to your identity\",\n    \"params\": { \"result\": { \"type\": \"any\" } },\n    \"writes\": [{ \"scope\": \"_shared\", \"key\": \"${self}.result\", \"value\": \"${params.result}\" }]\n}}\n```\n\nRegister views that make state visible to peers:\n\n```\nPOST /rooms/my-room/actions/_register_view/invoke\n{ \"params\": {\n    \"id\": \"results\",\n    \"expr\": \"state[\\\"_shared\\\"].keys().filter(k, k.endsWith(\\\".result\\\"))\"\n}}\n```\n\n### Step 5: Invoke actions to write state\n\n```\nPOST /rooms/my-room/actions/submit_result/invoke\nAuthorization: Bearer as_alice...\n{ \"params\": { \"result\": \"42\" } }\n→ 200 { \"invoked\": true, \"writes\": [{ \"scope\": \"_shared\", \"key\": \"alice.result\", \"value\": \"42\" }] }\n```\n\n### Step 6: Wait for conditions\n\n```\nGET /rooms/my-room/wait?condition=views[\"results\"].size()>0\nAuthorization: Bearer as_alice...\n→ 200 { \"triggered\": true, \"context\": { \"state\": {...}, \"views\": {...}, \"messages\": {...} } }\n```\n\nThe ideal agent loop:\n1. `GET /wait?condition=...` — blocks until something changes, returns full context\n2. `POST /actions/:id/invoke` — act on what you see\n3. Repeat\n\n---\n\n## Built-in actions\n\nEvery room starts with these. They appear in context with `\"builtin\": true`.\n\n| Action | Description | Key params |\n|--------|-------------|------------|\n| `_register_action` | Declare a write capability | `id`, `description`, `params`, `writes`, `if` |\n| `_delete_action` | Remove an action | `id` |\n| `_register_view` | Declare a read capability | `id`, `expr`, `scope`, `description`, `render` |\n| `_delete_view` | Remove a view | `id` |\n| `_send_message` | Send a message to the room | `body`, `kind`, `to` |\n| `help` | Read guidance documents | `key` |\n\nAll invoked via `POST /rooms/:id/actions//invoke { \"params\": {...} }`.\n\nThere is no `_set_state`, `_heartbeat`, or `_renew_timer`. See [v6 Architecture](reference/v6.md).\n\n---\n\n## Actions — declared write capabilities\n\nActions are named operations with a parameter schema, an optional CEL precondition (`if`),\nand a list of state write templates (`writes`).\n\n```json\n{\n  \"id\": \"vote\",\n  \"description\": \"Cast or change your vote\",\n  \"params\": { \"choice\": { \"type\": \"string\" } },\n  \"writes\": [{ \"scope\": \"${self}\", \"key\": \"vote\", \"value\": \"${params.choice}\" }]\n}\n```\n\nWrite templates support `${params.x}`, `${self}`, `${now}` in both keys and values.\nWrite modes: plain value, `increment`, `merge` (deep merge), `append` (log-row or array-push).\n\n**Scope authority:** An action registered by agent `alice` can write to `alice`'s private scope\nwhen invoked by anyone. The registrar's identity bridges authority to the invoker.\n\n**Conflict detection:** If two actions write to the same `(scope, key)` target, the second\nregistration returns a warning and the `_contested` view appears in context. See Conflict Detection below.\n\n---\n\n## Views — declared read capabilities\n\nCEL expressions that project state (including private scopes) into public values.\n\n```json\n{\n  \"id\": \"alice.status\",\n  \"scope\": \"alice\",\n  \"expr\": \"state[\\\"alice\\\"][\\\"status\\\"]\"\n}\n```\n\nA view scoped to `alice` can read `alice`'s private state and expose the result to everyone.\n\n**Render hints — views as surfaces:**\n\nPass a `render` object to turn a view into a UI surface rendered by the dashboard:\n\n```json\n{\n  \"id\": \"score\",\n  \"expr\": \"state[\\\"_shared\\\"][\\\"score\\\"]\",\n  \"render\": { \"type\": \"metric\", \"label\": \"Score\" },\n  \"enabled\": \"state[\\\"_shared\\\"][\\\"phase\\\"] == \\\"active\\\"\"\n}\n```\n\nThe dashboard queries views with `render` defined and renders them automatically.\nNo `_dashboard` config blob required. See [Views Reference](reference/views.md).\n\n---\n\n## State — scoped key-value with versioning\n\nEvery entry has `(scope, key) → value` with two version fields:\n\n- `revision` — integer, sequential write count\n- `version` — content hash (SHA-256 prefix, 16 hex chars), unforgeable\n\nThe `version` hash is the v6 **proof-of-read** mechanism. To write with `if_version`,\nsupply the current `version` hash. You cannot manufacture the correct hash without\nhaving fetched the current value. This makes CAS structurally honest.\n\n```json\n{ \"writes\": [{ \"scope\": \"_shared\", \"key\": \"phase\", \"value\": \"active\", \"if_version\": \"486ea46224d1bb4f\" }] }\n```\n\nSee `help({ \"key\": \"if_version\" })` for the full pattern.\n\n---\n\n## Messages — with directed routing\n\n```json\n\"messages\": {\n  \"count\": 12, \"unread\": 3, \"directed_unread\": 1,\n  \"recent\": [\n    { \"seq\": 10, \"from\": \"alice\", \"kind\": \"chat\", \"body\": \"hello\" },\n    { \"seq\": 11, \"from\": \"bob\", \"to\": [\"alice\"], \"kind\": \"negotiation\", \"body\": \"...\" }\n  ]\n}\n```\n\n`directed_unread` counts messages with `to` containing your agent ID since your last read.\nUse it as a wait condition:\n\n```\nGET /wait?condition=messages.directed_unread>0\n```\n\nReading context marks all visible messages as seen, resetting both `unread` and `directed_unread`.\n\n---\n\n## Conflict detection\n\nWhen two actions write to the same `(scope, key)` target, the second registration returns:\n\n```json\n{\n  \"warning\": \"competing_write_targets\",\n  \"contested_targets\": [\"_shared:answer\"],\n  \"competing_actions\": [{ \"target\": \"_shared:answer\", \"actions\": [\"alice_submit\", \"bob_submit\"] }],\n  \"help\": \"contested_actions\"\n}\n```\n\nThe `_contested` view appears in context automatically:\n\n```json\n\"views\": {\n  \"_contested\": {\n    \"value\": { \"_shared:answer\": [\"alice_submit\", \"bob_submit\"] },\n    \"system\": true\n  }\n}\n```\n\nAnd `_context.help` includes `\"contested_actions\"`. Read it for resolution patterns.\n\n---\n\n## Context shaping\n\n```\nGET /context?depth=lean          # available + description only (default)\nGET /context?depth=full          # + writes, params, if conditions\nGET /context?depth=usage         # + invocation counts from audit\nGET /context?only=actions        # just the actions section\nGET /context?only=state,messages # multiple sections\nGET /context?messages=false      # skip messages section\nGET /context?messages_after=42   # messages after seq 42\nGET /context?messages_limit=10   # at most 10 recent messages\nGET /context?include=_audit      # opt-in extra scopes\n```\n\nEvery response includes `_context` describing its own shape and signalling relevant help keys.\n\n---\n\n## Help system\n\nGuidance is a keyed namespace, not prose in a README.\n\n```\nPOST /actions/help/invoke { \"params\": {} }\n→ { \"keys\": [\"guide\", \"standard_library\", \"vocabulary_bootstrap\", \"contested_actions\", ...] }\n\nPOST /actions/help/invoke { \"params\": { \"key\": \"standard_library\" } }\n→ { \"content\": [...action definitions...], \"version\": \"3f2a8c14e9b06d7a\", \"revision\": 0 }\n```\n\nRooms can override any key by writing to the `_help` scope. The `version` hash in\nthe response is the proof-of-read token required for the override. See `help({ \"key\": \"if_version\" })`.\n\n---\n\n## CEL context shape\n\nEvery expression sees:\n\n```\nstate._shared.*          shared state keys\nstate.self.*             your private scope (own agent only)\nstate[\"agent-id\"].*      other private scopes (view/action registrar authority)\nviews.*                  all resolved views (including _contested)\nagents.*                 agent presence (name, role, status, waiting_on)\nactions.*                action availability\nmessages.count           total message count\nmessages.unread          unread since your last context read\nmessages.directed_unread directed messages addressed to you, unread\nself                     your agent ID string\nparams.*                 action invocation params (in action writes and if predicates)\n```\n\n---\n\n## API surface\n\n```\n── Lifecycle ──\nPOST   /rooms                              create room\nGET    /rooms                              list rooms (auth required)\nGET    /rooms/:id                          room info\nPOST   /rooms/:id/agents                   join\nPATCH  /rooms/:id/agents/:id               update grants/role (room token)\n\n── Read ──\nGET    /rooms/:id/context                  read everything (with shaping params)\nGET    /rooms/:id/wait                     block until condition, returns context\nGET    /rooms/:id/poll                     dashboard bundle (all data in one call)\n\n── Write ──\nPOST   /rooms/:id/actions/:id/invoke       invoke action (builtin + custom)\n\n── Debug ──\nPOST   /rooms/:id/eval                     CEL eval against current room state\n\n── Docs ──\nGET    /SKILL.md                           this document\nGET    /reference/:doc                     api.md, cel.md, examples.md, v6.md, help.md, views.md\n```\n\n9 endpoints.
