Interact entirely via email — send messages, tasks, ideas, and memories to **`memory-do@valtown.email`** and the agent classifies, stores, executes, and replies.\n\n## How It Works\n\nSend an email. The agent reads it, figures out what you mean, and acts on it.\n\n```\nYou → \"Remind me Thursday to call the dentist\"\n → \"I like chickens\"\n → \"What's the latest news on WebAssembly?\"\n → \"Every Monday, give me a summary of my active tasks\"\n```\n\nUnder the hood:\n\n1. **Classify** — Claude analyzes your email and extracts structured entries (memories, tasks, ideas, people, meetings, projects)\n2. **Store** — Everything goes into a unified SQLite database with full-text search and a relationship graph linking entries together\n3. **Execute** — Instant tasks run immediately through an agentic loop; future/recurring tasks get scheduled\n4. **Reply** — You get an email back with results, follow-up questions, and any generated file attachments\n\n### Voice-Friendly\n\nEmails sent via voice transcription work great. The classifier is tuned for misspellings, run-on sentences, and implicit intent — it interprets what you *mean*, not what you literally typed.\n\n## Agentic Execution\n\nThe agent doesn't just make a single LLM call and reply. It runs an **iterative tool-use loop** — Claude can call tools mid-task to gather information, search the web, query your stored knowledge, and create follow-up work.\n\n```\n┌─────────────────────────────────────────────┐\n│ 1. Load user context (memories, tasks, etc) │\n│ 2. Send task + context + tools to Claude │\n│ 3. Claude responds: │\n│ ├─ Final answer? → Done, send reply │\n│ └─ Tool call? → Execute tool, loop to 2 │\n│ 4. Safety: max 15 iterations │\n│ 5. Extract attachments, generate subject │\n└─────────────────────────────────────────────┘\n```\n\n### Available Tools\n\n| Tool | What It Does |\n|---|---|\n| `search_memories` | Full-text search across all your stored entries |\n| `get_entries` | Browse entries by type (all tasks, all people, all ideas, etc.) |\n| `get_linked_entries` | Traverse the relationship graph between entries |\n| `store_memory` | Save new facts discovered during task execution |\n| `create_task` | Create follow-up tasks — instant, future, or recurring |\n| `fetch_url` | Fetch live data from the web (news, APIs, weather, docs) |\n\nThis means the agent can do multi-step research: search your memories, fetch a web page, cross-reference with your stored projects, save what it learned, and compose a rich reply — all in one email exchange.\n\n## What Gets Stored\n\nEverything is an **entry** with a type. The system is extensible — new types need zero code changes.\n\n| Type | Example |\n|---|---|\n| `memory` | \"I work at Acme Corp\", \"I like chickens\" |\n| `task` | \"Remind me Thursday to call the dentist\" |\n| `idea` | \"I have an idea for a recipe app...\" |\n| `person` | \"My friend Sarah works at Google\" |\n| `meeting` | \"Lunch with Bob on Friday at noon\" |\n| `project` | \"I'm building a Chrome extension\" |\n| `interaction` | Every email sent/received (automatic) |\n\nEntries are linked to each other in a relationship graph — \"this idea became this project\", \"these entries came from the same email\", \"this person is connected to this meeting\".\n\n## Task Types\n\n| Type | Behavior | Example |\n|---|---|---|\n| **Instant** | Executes immediately, reply in same email | \"What's the weather in London?\" |\n| **Future** | Scheduled for a specific time | \"Remind me Thursday at 10am to call dentist\" |\n| **Recurring** | Repeats on a schedule | \"Every Monday, summarize my active tasks\" |\n\nFuture and recurring tasks are processed by a task runner that checks every 15 minutes.\n\n## Per-User Personalization\n\nEach user gets a persistent system prompt — a personal \"CLAUDE.md\" that shapes how the agent behaves for them.\n\nSet it by emailing instructions:\n- *\"Be more casual and use emojis\"*\n- *\"Call me Paul\"*\n- *\"Always use bullet points\"*\n- *\"Don't be so wordy\"*\n\nThese are extracted automatically and applied to every future interaction.\n\n## Attachments\n\nFull bidirectional support:\n\n- **Inbound** — Email attachments (CSV, JSON, text, code files, etc.) are stored and their content is fed to both the classifier and the agent as context\n- **Outbound** — The agent can generate files (reports, CSV exports, data dumps) and send them back as email attachments\n\n## Architecture\n\n```\nemail-agent/\n README.md ← You are here\n CLAUDE.md — Internal dev guide and conventions\n main.ts — HTTP admin/debug endpoint\n email-handler.ts — Email ingestion (memory-do@valtown.email)\n task-runner.ts — Scheduled task processor (runs every 15 min)\n lib/\n classifier.ts — Claude-powered email → structured entries\n agent.ts — Agentic task execution with tool-use loop\n scheduler.ts — Natural language → ISO datetime\n attachments.ts — Blob storage for inbound/outbound files\n db/\n schema.ts — SQLite schema (entries + FTS5 + links)\n queries.ts — CRUD, search, user context builder\n```\n\n### Tech Stack\n\n- **Runtime**: [Val Town](https://val.town) (Deno-based serverless)\n- **LLM**: Claude Sonnet via [Anthropic SDK](https://docs.anthropic.com/en/docs/build-with-claude/tool-use)\n- **Database**: Project-scoped SQLite with FTS5 full-text search\n- **Storage**: Val Town Blob API for attachments\n- **Email**: Val Town email sending/receiving\n\n### Data Flow\n\n```\n ┌──────────────┐\n │ Incoming │\n │ Email │\n └──────┬───────┘\n │\n ┌──────▼───────┐\n │ Classifier │ ← Claude: extract entries, instructions, follow-ups\n │ (1 LLM call) │\n └──────┬───────┘\n │\n ┌──────▼───────┐\n │ Store in DB │ ← Entries, FTS sync, cross-links\n └──────┬───────┘\n │\n ┌───────┴────────┐\n │ │\n ┌────▼─────┐ ┌─────▼──────┐\n │ Instant │ │ Future / │\n │ Tasks │ │ Recurring │\n │ │ │ Tasks │\n │ ┌───────┐ │ │ │\n │ │ Agent │ │ │ Queued for │\n │ │ Loop │ │ │ task-runner│\n │ │ ↻ │ │ └────────────┘\n │ └───┬───┘ │\n │ │ │\n └─────┼─────┘\n │\n ┌─────▼─────┐\n │ Reply │ ← Results + attachments + follow-up questions\n │ Email │\n └────────────┘\n```\n\n## Environment Variables\n\n| Variable | Required | Description |\n|---|---|---|\n| `ANTHROPIC_API_KEY` | Yes | Used by all Claude API calls (classifier, scheduler, agent) |\n\n## Admin / Debugging\n\nThe HTTP endpoint (`main.ts`) provides:\n\n- `GET /` or `GET /stats` — System-wide entry counts, entries by type, link counts\n- `GET /user/:email` — Full user profile with entries grouped by type\n\n## Limitations\n\n- **No conversation threading** — Each email is independent (though recent history is loaded as context)\n- **Plain text replies** — No HTML email rendering\n- **No admin auth** — HTTP endpoints are open\n- **No rate limiting** — No flood protection\n- **No memory deduplication** — Semantic similarity dedup not yet implemented\n- **No system prompt reset** — Users can add instructions but can't easily clear them yet\n\n## License\n\nBuilt on Val Town.

Users interact entirely via email — sending messages, tasks, ideas, and memories to `memory-do@valtown.email`.

Email arrives at `memory-do@valtown.email`\n2. Sender is identified/created as a user\n3. Interaction is logged as an entry (type: `interaction`)\n4. Email is classified by Claude into **unified entries** — any type: memories, tasks, ideas, people, meetings, projects, or anything new\n5. System instructions are extracted and persisted to the user's personal system prompt\n6. All entries are stored in the unified `entries` table with FTS synced\n7. Entries are cross-linked to each other and to the source interaction\n8. Instant tasks execute immediately via the agent; results are emailed back\n9. Future/recurring tasks are queued with computed `next_run_at` timestamps\n10. Acknowledgment email is sent summarizing what was captured, with follow-up questions\n\n### Task Runner (task-runner.ts)\n- Runs on an interval (every 15 minutes)\n- Finds task entries where `next_run_at <= now` and `status = 'pending'`\n- Executes each via the agent with full user context (including per-user system prompt)\n- Emails results to the user\n- Recurring tasks get rescheduled to their next occurrence\n- Failed tasks still get rescheduled if recurring\n\n### HTTP Admin (main.ts)\n- `GET /` or `GET /stats` — system-wide counts, entries by type, link counts\n- `GET /user/:email` — full user profile with entries grouped by type and links\n- `GET /migrate` — one-time migration from old tables to unified schema\n\n## Database\n\nUses **project-scoped SQLite** (`std/sqlite/main.ts`). Do NOT change to `std/sqlite` or `std/sqlite/global.ts` — this project uses its own database, not the user's global one.\n\n### Unified Model\n\nEverything is an **entry** with a `type` column. No new tables needed for new content types — just use a new type string.\n\n### Tables\n\n- **users** — unique sender emails, optional name, **per-user system_prompt** (their personal \"CLAUDE.md\")\n- **entries** — all content: memories, tasks, ideas, interactions, people, meetings, projects, and any future type\n- **entry_links** — relationship graph between entries (cross-references, co-extraction, parent-child, etc.)\n\n### Entry Types (non-exhaustive — new types can be added without schema changes)\n\n| Type | Purpose | Key metadata fields |\n|---|---|---|\n| `memory` | Long-term facts/preferences | `{ category: \"preference\" \\| \"fact\" \\| \"context\" \\| \"general\" }` |\n| `task` | Actionable items | `{ task_type: \"instant\" \\| \"future\" \\| \"recurring\", result: \"...\" }` |\n| `idea` | Captured ideas (explicit only) | `{ status: \"seed\" \\| \"exploring\" \\| ... }` |\n| `interaction` | Raw email log | `{ direction: \"inbound\" \\| \"outbound\" }` |\n| `person` | People mentioned by the user | `{ relationship: \"...\", contact: { ... } }` |\n| `meeting` | Scheduled conversations | `{ with: [...], date: \"...\", agenda: [...] }` |\n| `project` | Active codebases/builds | `{ repo: \"...\", url: \"...\", tech: [...] }` |\n\n### Entry Fields\n\n- `id` — primary key\n- `user_id` — owner\n- `type` — the content type (any string)\n- `status` — lifecycle: `active`, `pending`, `in_progress`, `completed`, `failed`, `archived`\n- `title` — optional, used by tasks/ideas/meetings\n- `content` — the main body text (always present)\n- `tags` — comma-separated, searchable via FTS\n- `metadata` — JSON blob for type-specific fields\n- `source_entry_id` — which entry spawned this (creates a provenance chain)\n- `next_run_at` — for scheduled entries (tasks, meeting reminders)\n- `schedule_description` — natural language schedule for recurring entries\n- `created_at`, `updated_at` — timestamps\n\n### Entry Links (the Graph)\n\nThe `entry_links` table creates a relationship graph between entries:\n- `from_entry_id` → `to_entry_id` with a `relationship` label\n- Relationships: `related`, `created`, `co_extracted`, `parent`, `blocks`, `became`, etc.\n- Enables: \"This idea became this project\", \"These entries were extracted from the same email\", \"This person is connected to this meeting\"\n\n### FTS5\n\nSingle `entries_fts` table covers all entry types. Indexes `title`, `content`, and `tags`. Synced manually on every insert in `queries.ts`.\n\n### Indexes\n- `idx_entries_user_type` — entries by user + type\n- `idx_entries_user_status` — entries by user + status\n- `idx_entries_pending_run` — partial index for due task lookup\n- `idx_entries_type_created` — entries by type + creation date\n- `idx_entry_links_from/to` — link traversal\n\n## Per-User System Prompt\n\nEach user has a `system_prompt` column on the `users` table — their personal \"CLAUDE.md\" that controls how the agent behaves for them.\n\n### How it works:\n1. User emails: \"Be more casual and always use emojis. Call me Paul.\"\n2. Classifier extracts `system_instructions`: `[\"Use casual, informal tone with emojis\", \"Address user as Paul\"]`\n3. Email handler calls `updateSystemPrompt()` — appends new instructions, deduplicates\n4. Every future agent call loads this prompt and injects it into the system prompt as \"User's Personal Instructions\"\n5. User can see their prompt via the admin endpoint, or say \"show me my preferences\"\n\n### What it captures:\n- Tone/style preferences (\"be concise\", \"use bullet points\")\n- Name/addressing preferences (\"call me Captain\")\n- Format preferences (\"always include a summary section\")\n- Any standing instruction the user gives\n\n## Attachments\n\nFull bidirectional attachment support — receive files from users and send generated files back.\n\n### Inbound (Receiving)\n- Email attachments arrive as `File` objects in `email.attachments[]`\n- Each is stored in **blob storage** with key `attachments/{userId}/{entryId}/{filename}`\n- Metadata is tracked in the **`attachments`** table (filename, MIME type, size, blob key, is_text flag)\n- Text-readable files (txt, csv, json, md, html, xml, code files) have their content extracted and:\n - Fed to the **classifier** as part of the email body\n - Available to the **agent** when executing tasks via `getTextAttachmentContents()`\n- Binary files (images, PDFs, zips) are stored but content is not extracted\n\n### Outbound (Generating)\n- The agent can generate files by including `` tags in its response:\n ```\n \n col1,col2\n val1,val2\n \n ```\n- These are parsed from the response, stored in blob storage, and sent as email attachments\n- Both `email-handler.ts` (instant tasks) and `task-runner.ts` (scheduled tasks) handle outbound attachments\n- Outbound interaction entries record `attachment_count` and `attachment_names` in metadata\n\n### Storage\n- **Blob storage**: `@valtown/sdk` blob API — actual file content\n- **`attachments` table**: metadata linking blobs to entries and users\n- **Max inbound text extraction**: 100KB per file (configurable in `lib/attachments.ts`)\n\n### Tables\n```sql\nattachments (\n id, entry_id, user_id, filename, mime_type, size_bytes,\n blob_key, is_text, created_at\n)\n```\n\n## Environment Variables\n\n- **ANTHROPIC_API_KEY** — required. Used by all Claude API calls (classifier, scheduler, agent). Accessed implicitly by the Anthropic SDK.\n\n## Dependencies\n\n- `npm:@anthropic-ai/sdk@0.39.0` — Claude API client (pin the version)\n- `https://esm.town/v/std/sqlite/main.ts` — project-scoped SQLite\n- `https://esm.town/v/std/email` — Val Town email sending\n\n## Conventions\n\n### Code Style\n- TypeScript everywhere (.ts files only)\n- File and val names in **kebab-case** (e.g., `email-handler.ts`, `task-runner.ts`)\n- Interfaces for all data shapes crossing boundaries (API responses, DB rows, function params)\n- Always use parameterized queries (`args`) — never interpolate user input into SQL\n- Emoji prefixes in console.log for easy scanning: 📧 📝 🧠 📊 💾 💡 ⏰ 🔄 ⚡ ✅ ❌ 📤 🔧 📋 🧬 👤\n\n### Error Handling\n- Every email processing step is wrapped in try/catch\n- Task failures still send a notification email to the user\n- Recurring tasks get rescheduled even on failure\n- FTS search failures are non-fatal (empty tables can cause issues)\n- JSON parse failures in classifier/scheduler fall back to sensible defaults\n\n### LLM Calls\n- All Claude calls use `claude-sonnet-4-20250514` — keep this consistent\n- System prompts are defined as module-level constants (not inline)\n- Per-user system prompt is injected dynamically from the `users.system_prompt` column\n- Responses are parsed via regex (`/\\{[\\s\\S]*\\}/`) to extract JSON from potential markdown code blocks\n- Always have a fallback if JSON parsing fails\n\n### Database Patterns\n- `initDatabase()` is called at the top of every entry point — safe to call multiple times (`CREATE TABLE IF NOT EXISTS`)\n- FTS inserts happen immediately after main table inserts in `addEntry()`\n- Use `Promise.all` for independent parallel queries\n- `getUserContext()` is the canonical way to build a user context bundle for the agent\n- `metadata` is stored as JSON string, parsed in `parseEntryRow()`\n\n### Classifier Output\n- Returns a unified `entries[]` array — each entry has a `type` and optional `metadata`\n- `system_instructions[]` — persistent instructions extracted for the user's prompt\n- `follow_up_questions[]` — natural follow-ups included in the acknowledgment email\n- New entry types can be output by the classifier without any code changes\n- Voice input tolerance: the classifier prompt explicitly handles transcription errors\n\n## Working Style\n\n- **Don't break the email flow** — `email-handler.ts` is the critical path. Changes there should be tested carefully. A broken email handler means users get no response.\n- **Idempotent schema** — `initDatabase()` must always be safe to re-run. Use `IF NOT EXISTS` on everything.\n- **Keep classifier prompts tight** — The classification prompt directly controls what gets stored. Be precise about what counts as each type. Over-extraction creates noise.\n- **Ideas require explicit intent** — The classifier is specifically instructed to only capture ideas the user explicitly asks to store. Don't weaken this.\n- **Agent has full context** — When executing tasks, the agent gets memories, active tasks, recent ideas, recent conversations, FTS search results, AND the user's personal system prompt.\n- **Multiple Claude calls per task execution** — The agentic loop may make several calls (one initial + N tool-use rounds + 1 subject line). Log `toolCallCount` and `iterationCount` to monitor costs. The subject line is still a separate call.\n- **Voice input tolerance** — Users may send emails via voice transcription. Expect imperfect input. Interpret intent rather than demanding precision.\n- **Cross-link everything** — Every entry should be linked to its source and to related entries. The graph is what makes context retrieval powerful.\n- **Follow-up questions** — After processing, include 1-2 natural follow-ups in the reply to help deepen the conversation. Don't force them.\n\n## Agentic Tool-Use Loop\n\nThe agent (`lib/agent.ts`) uses an **iterative tool-use loop**, not a one-shot request-reply.\n\n### How it works:\n1. Build initial context (memories, tasks, ideas, conversations, attachments, FTS search)\n2. Send to Claude with **tool definitions** — Claude can call tools mid-execution\n3. **Loop**: If Claude returns `tool_use` blocks, execute each tool and feed results back\n4. **Repeat** until Claude returns a final `end_turn` response (or max 15 iterations)\n5. If max iterations hit, ask Claude to wrap up with what it has\n\n### Available Tools:\n| Tool | Purpose | DB function used |\n|---|---|---|\n| `search_memories` | Full-text search across all entry types | `searchEntries()` |\n| `get_entries` | Browse entries by type/status | `getEntries()` |\n| `get_linked_entries` | Traverse the entry relationship graph | `getLinkedEntries()` |\n| `store_memory` | Save a new memory discovered during task execution | `addEntry()` |\n| `create_task` | Create follow-up/sub-tasks (instant, future, recurring) | `addEntry()` + `parseSchedule()` |\n| `fetch_url` | Fetch live data from the web (news, APIs, weather, etc.) | `fetch()` |\n\n### Constants:\n- `MAX_TOOL_ITERATIONS = 15` — safety limit on the loop\n- `fetch_url` timeout: 15 seconds, response limit: 50KB\n- HTML responses are auto-stripped of tags for readability\n\n### AgentResult includes:\n- `response` — the final text response\n- `suggestedSubject` — email subject line (separate Claude call)\n- `attachments` — generated file attachments\n- `toolCallCount` — total number of tool calls made\n- `iterationCount` — total number of loop iterations\n\n## Known Limitations & Future Improvements\n\n- **No conversation threading** — Each email is processed independently. The agent has recent interaction history but doesn't maintain true conversation threads.\n- **No email HTML rendering** — Replies are plain text only.\n- **No auth on HTTP admin** — The endpoints are open. Add authentication if this becomes public-facing.\n- **No rate limiting** — No protection against flooding.\n- **No memory deduplication** — Same fact can be stored multiple times. Could use semantic similarity to deduplicate.\n- **Single Claude model** — All calls use the same model. Could use a lighter model for scheduling/subject lines.\n- **No system prompt reset** — User can add instructions but can't easily remove or reset them yet. Add \"reset my preferences\" as a recognized command.\n\n## Evolving the System\n\nThis agent should grow organically based on usage patterns. When you notice recurring needs:\n\n1. **New entry types need zero code changes** — just use a new type string in the classifier. The unified model handles it.\n2. **Refine classification** — If the classifier is miscategorizing things, tighten the prompt. Log examples of misclassifications.\n3. **New link relationships** — If new relationships emerge between entries, add relationship types to `entry_links`.\n4. **Proactive suggestions** — The agent should notice patterns and suggest improvements, like the journal system's \"Claude Tasks\" concept.\n5. **Keep this file updated** — When the system changes, update CLAUDE.md. This is the source of truth.\n\n## Migration\n\nThe system was migrated from separate tables (memories, tasks, ideas, interactions) to a unified `entries` table. The old tables still exist but are no longer used. The `/migrate` endpoint runs the migration. Old FTS tables (`memories_fts`, `tasks_fts`, `ideas_fts`, `interactions_fts`) are superseded by `entries_fts`.\n",[176],"5e83aa1c-18bf-11f1-867c-42dde27851f2","CLAUDE-v2.md","5e83aa9e-18bf-11f1-867c-42dde27851f2",["D",1772734562850],"# Email Agent System — v2 (Sandbox Architecture)\n\nAn email-based personal AI agent built on Val Town. Users interact entirely via email — sending messages, tasks, ideas, and memories to `memory-do@valtown.email`. The agent processes requests inside per-user Deno Sandboxes with full Linux tooling.\n\n## Architecture Overview\n\n```\n┌───────────────────────────────────────────────────────────────┐\n│ VAL TOWN (orchestrator) │\n│ │\n│ email-handler-v2.ts (email) → receives email │\n│ │ │\n│ ├─ Get/create user (SQLite: users table) │\n│ ├─ Write email to user's sandbox inbox │\n│ ├─ Boot sandbox → run agent-loop.mjs │\n│ ├─ Read response from sandbox outbox │\n│ ├─ Process schedule.json → scheduled_tasks table │\n│ └─ Send reply email │\n│ │\n│ task-runner-v2.ts (interval, every 15 min) │\n│ │ │\n│ ├─ Query scheduled_tasks WHERE next_run_at <= now │\n│ ├─ For each due task: │\n│ │ ├─ Write task to user's sandbox inbox │\n│ │ ├─ Boot sandbox → run agent-loop.mjs │\n│ │ ├─ Read response, email user │\n│ │ └─ Reschedule if recurring │\n│ └─ Done │\n│ │\n│ main.ts (http) → admin/status dashboard │\n└───────────────────┬───────────────────────────────────────────┘\n │\n ▼\n┌───────────────────────────────────────────────────────────────┐\n│ DENO SANDBOX (per-user microVM) │\n│ │\n│ Runs: node /opt/agent/agent-loop.mjs │\n│ Uses: Claude Agent SDK with Bash/Read/Write/Edit/Glob/Grep │\n│ Mounts: user's persistent volume at /home/user/ │\n│ │\n│ /home/user/ │\n│ ├── CLAUDE.md ← agent instructions (Claude edits it!) │\n│ ├── agents.md ← persona/identity │\n│ ├── TODO.md ← persistent task list │\n│ ├── memories/ ← knowledge as markdown files │\n│ ├── ideas/ ← captured ideas │\n│ ├── people/ ← people directory │\n│ ├── repos/ ← cloned git repositories │\n│ ├── workspace/ ← scratch area │\n│ ├── .ssh/ ← SSH keys │\n│ ├── .mail/ │\n│ │ ├── inbox/ ← tasks arrive here (written by VT) │\n│ │ └── outbox/ ← responses go here (written by agent) │\n│ └── .agent-results/ ← cycle metrics (turns, cost, timing) │\n└───────────────────────────────────────────────────────────────┘\n```\n\n## File Structure\n\n```\nemail-agent/\n CLAUDE.md — Original system docs (v1, still active on main)\n CLAUDE-v2.md — This file. Sandbox architecture docs.\n README.md — Project overview\n\n # V2 (sandbox architecture) — on sandbox-integration branch\n email-handler-v2.ts — Email ingestion → sandbox execution (type: email)\n task-runner-v2.ts — Scheduled task polling → sandbox execution (type: interval)\n main.ts — HTTP endpoint for status/admin (type: http)\n db/\n schema-v2.ts — Simplified: users + scheduled_tasks + sandbox_executions\n lib/\n sandbox-orchestrator.ts — Volume CRUD, sandbox boot, result reading\n sandbox-agent-loop.ts — Source code for agent-loop.mjs (runs in sandbox)\n sandbox-claude-md.ts — Builds CLAUDE.md and agents.md for user volumes\n scheduler.ts — Natural language → ISO datetime (unchanged)\n admin/\n build-snapshot.ts — Builds the toolchain sandbox snapshot\n\n # V1 (original architecture) — still on main branch\n email-handler.ts — Original email handler with classifier\n task-runner.ts — Original task runner\n lib/\n classifier.ts — Email classification (replaced by sandbox agent)\n agent.ts — Tool-use agent loop (replaced by sandbox agent)\n attachments.ts — Blob-based attachments (replaced by sandbox files)\n db/\n schema.ts — Original unified schema with entries/FTS/links\n queries.ts — Original queries\n```\n\n## Key Design Principles\n\n### 1. The Volume IS the User's Brain\nAll user state lives on their persistent sandbox volume as plain files:\n- **Memories** → `memories/*.md` (one file per topic, Claude organizes)\n- **Tasks** → `TODO.md` (Claude maintains it directly)\n- **Ideas** → `ideas/*.md` (one per idea)\n- **People** → `people/*.md` (one per person)\n- **Preferences** → embedded in `CLAUDE.md` (Claude edits it!)\n- **SSH keys** → `.ssh/` (standard Unix location)\n- **Git repos** → `repos/` (persistent across sessions)\n\nNo more SQL for content storage. No FTS tables. No entry_links graph.\nClaude manages files naturally because it has Bash/Read/Write/Edit tools.\n\n### 2. SQLite = Thin Routing Layer\nSQLite only stores what Val Town needs to operate:\n- **users**: email → user mapping + volume reference\n- **scheduled_tasks**: when to wake up the sandbox (task runner polls this)\n- **sandbox_executions**: execution log for debugging and cost tracking\n\n### 3. The Sandbox Agent Does Everything\nNo more classifier, no more custom tool definitions, no more agent.ts loop.\nThe agent-loop.mjs inside the sandbox uses the **Claude Agent SDK** with:\n- `Bash` — run any command (git, npm, python, curl, etc.)\n- `Read` — read any file\n- `Write` — write any file\n- `Edit` — edit files with diffs\n- `Glob` — find files by pattern\n- `Grep` — search file contents\n\nClaude reads CLAUDE.md on the volume, checks the inbox, decides what to do,\ndoes it, and writes results to the outbox. The orchestrator just reads the output.\n\n### 4. Inbox/Outbox File Convention\nCommunication between Val Town and the sandbox is via files:\n- **Orchestrator → Sandbox**: writes task files to `.mail/inbox/`\n- **Sandbox → Orchestrator**: writes response files to `.mail/outbox/`\n- **Schedule requests**: agent writes `.mail/outbox/schedule.json`\n- **File attachments**: agent writes `.mail/outbox/response-{id}.files.json`\n\n## Database (v2)\n\nUses **project-scoped SQLite** (`std/sqlite/main.ts`). Do NOT change to `std/sqlite` or `std/sqlite/global.ts`.\n\n### Tables\n\n#### users\n```sql\nusers (\n id, email, name, volume_slug, volume_id,\n volume_region, sandbox_snapshot, created_at, updated_at\n)\n```\n\n#### scheduled_tasks\n```sql\nscheduled_tasks (\n id, user_id, title, description, next_run_at,\n schedule_description, is_recurring, status, created_at, updated_at\n)\n```\n\n#### sandbox_executions\n```sql\nsandbox_executions (\n id, user_id, trigger_type, trigger_id,\n status, turns, cost_usd, elapsed_ms, error_message,\n created_at, completed_at\n)\n```\n\n## Sandbox Lifecycle\n\n### Email Flow\n1. Email arrives → `email-handler-v2.ts`\n2. Get/create user from sender email\n3. Call `executeSandboxTask()`:\n a. Get/create user's volume (provisions if first time)\n b. Write email content to `.mail/inbox/task-{id}-{slug}.md`\n c. Boot sandbox, mount user's volume\n d. Run `node /opt/agent/agent-loop.mjs`\n e. Agent reads CLAUDE.md, reads inbox, processes task\n f. Agent writes response to `.mail/outbox/response-{id}.md`\n g. Agent optionally writes `schedule.json`, `files.json`\n h. Orchestrator reads outbox, shuts down sandbox\n4. Process schedule requests → insert into `scheduled_tasks`\n5. Send response email to user\n\n### Scheduled Task Flow\n1. `task-runner-v2.ts` fires every 15 min\n2. Query `scheduled_tasks` for due tasks\n3. For each: `executeSandboxTask()` (same as above)\n4. Email results to user\n5. Reschedule recurring tasks\n\n### Volume Initialization\nFirst time a user needs a sandbox:\n1. Create a persistent volume via `Client.volumes.create()` (slug: `email-agent-user-{userId}`, region: `ord`, capacity: `1GB`)\n2. Record volume_slug in users table\n3. Boot sandbox with volume mounted at `/home/app` via `Sandbox.create({ volumes: { \"/home/app\": slug } })`\n4. Create directory structure: `.mail/inbox`, `.mail/outbox`, `memories/`, etc.\n5. Write initial CLAUDE.md, agents.md, TODO.md\n6. Install agent-loop.mjs and dependencies\n7. All subsequent runs mount the same volume — memories, files, and agent state persist\n\n## Environment Variables\n\n- **ANTHROPIC_API_KEY** — required. Passed into sandboxes for Claude API calls.\n\n## Dependencies\n\n- `jsr:@deno/sandbox` — Deno Sandbox SDK (Client for volumes, Sandbox for execution)\n- `npm:@anthropic-ai/sdk@0.39.0` — Claude API client (for scheduler.ts)\n- `https://esm.town/v/std/sqlite/main.ts` — project-scoped SQLite\n- `https://esm.town/v/std/email` — Val Town email sending\n\n## Conventions\n\n### Code Style\n- TypeScript everywhere (.ts files only)\n- File and val names in **kebab-case**\n- Always use parameterized SQL queries (`args`)\n- Emoji prefixes in console.log: 📧 📝 🧠 📊 💾 💡 ⏰ 🔄 ⚡ ✅ ❌ 📤 🔧 📋 🚀\n\n### Error Handling\n- Every sandbox execution is wrapped in try/catch\n- Task failures still send a notification email\n- Recurring tasks get rescheduled even on failure\n- Sandbox boot failures return a user-friendly error message\n\n### Sandbox Conventions\n- User volumes are named `email-agent-user-{userId}`\n- Sandbox region: `us-east-1` (configurable in orchestrator)\n- Sandbox timeout: 5 min per execution\n- Agent cycle timeout: 3 min (inside the sandbox)\n- Agent max turns: 30\n\n## Migration from v1\n\nTo migrate from the original architecture:\n1. For each user in the `users` table:\n a. Provision a volume\n b. Export their entries as markdown files → write to volume\n c. Export their system_prompt → write to CLAUDE.md on volume\n2. Switch email-handler.ts to email-handler-v2.ts\n3. Switch task-runner.ts to task-runner-v2.ts\n4. Original DB tables remain as read-only backup\n\n## Known Limitations & Future Work\n\n- **Sandbox boot latency**: ~2-5 seconds per execution. Not ideal for trivial questions. Consider a fast-path that skips the sandbox for simple queries.\n- **Concurrency**: Deno Sandbox has a 5 concurrent limit during pre-release. With multiple users emailing simultaneously, may need queuing.\n- **Volume persistence model**: Each user gets a dedicated Deno Sandbox volume (slug: `email-agent-user-{userId}`) mounted at `/home/app`.

Expect:\n- Misspellings, homophones (\"stone\" for \"some\", \"bio connect\" for \"I/O Connect\")\n- Run-on sentences without punctuation\n- Implicit intent rather than explicit commands\nInterpret what the user MEANS, not what they literally typed.\n\nGiven an email, extract a list of **entries** — each with a type. Be thorough — a single email may contain multiple entries across types.\n\n## Entry Types\n\n**memory** — Facts, preferences, or context about the user to remember long-term.\n - metadata: { \"category\": \"preference\" | \"fact\" | \"context\" | \"general\" }\n - Examples: \"I like chickens\", \"I work at Acme Corp\", \"My portfolio includes AAPL\"\n\n**task** — Something that needs to be done. Set the metadata.task_type to classify when:\n - metadata: { \"task_type\": \"instant\" | \"future\" | \"recurring\" }\n - instant: needs an immediate response/action NOW. E.g. \"What's the weather?\", \"Draft me an email\"\n - future: do at a specific future time. E.g. \"Remind me Thursday to call dentist\". Include schedule field.\n - recurring: do on a regular schedule. E.g. \"Every Monday, analyze stocks\". Include schedule field.\n - Set status to \"pending\" for all tasks.\n\n**idea** — ONLY capture ideas the user **explicitly** asks to store. Look for signals like:\n - \"I have an idea...\", \"Store this idea...\", \"Here's a thought I want to remember...\"\n - Do NOT infer ideas from general content. If something *could* be an idea but isn't framed as one, skip it.\n\n**person** — When the user mentions a specific person with details worth remembering.\n - metadata: { \"relationship\": \"...\", \"contact\": { ... }, \"connections\": [] }\n - Examples: \"My friend Sarah works at Google\", \"Bob's number is 555-1234\"\n\n**meeting** — When the user mentions a scheduled conversation or event.\n - metadata: { \"with\": [\"...\"], \"date\": \"...\", \"time\": \"...\", \"agenda\": [\"...\"] }\n - Include a schedule field with the meeting time for reminder scheduling.\n\n**project** — When the user discusses something they're actively building.\n - metadata: { \"repo\": \"...\", \"url\": \"...\", \"tech\": [\"...\"] }\n\nYou can use ANY type string — if something doesn't fit the above, invent an appropriate type.\n\n## System Instructions\n\nIf the user gives persistent instructions about how the agent should behave, extract them as system_instructions. These are things like:\n- \"Be more casual\" → \"Use casual, informal tone\"\n- \"Call me Paul\" → \"Address the user as Paul\"\n- \"Always use bullet points\" → \"Format responses using bullet points\"\n- \"Don't be so wordy\" → \"Keep responses concise and brief\"\n\nOnly extract these when the user is clearly giving a STANDING instruction, not a one-time request.\n\n## Follow-Up Questions\n\nSuggest 1-2 natural follow-up questions that would help deepen the conversation or capture more useful information. Keep them short and conversational. Examples:\n- After a task: \"Any deadline for this?\"\n- After a person mention: \"Want me to remember anything else about them?\"\n- After an idea: \"What problem does this solve?\"\n- After a memory: \"How does this connect to [something else you know about them]?\"\n\nOnly include follow-ups when they'd genuinely be useful. Don't force them.\n\n## Response Format\n\nRespond with ONLY valid JSON:\n{\n \"entries\": [\n {\n \"type\": \"memory\",\n \"content\": \"Likes chickens and cows\",\n \"metadata\": { \"category\": \"preference\" }\n },\n {\n \"type\": \"task\",\n \"title\": \"Check weather in London\",\n \"content\": \"Find the current weather in London and report back\",\n \"status\": \"pending\",\n \"metadata\": { \"task_type\": \"instant\" }\n },\n {\n \"type\": \"task\",\n \"title\": \"Call dentist\",\n \"content\": \"Remind to call the dentist about the appointment\",\n \"status\": \"pending\",\n \"metadata\": { \"task_type\": \"future\" },\n \"schedule\": \"next Thursday at 10am\"\n }\n ],\n \"system_instructions\": [],\n \"follow_up_questions\": [],\n \"reply_needed\": true,\n \"summary\": \"Brief one-line summary of what this email is about\"\n}\n\nIf a field has no items, return an empty array.

Good when the task references something the user told you before.\n- **get_entries**: Browse entries by type. Use to find all tasks, all people, all ideas, etc.\n- **get_linked_entries**: Follow relationships between entries. \"What was this entry connected to?\"\n- **store_memory**: When you learn a new fact about the user during task execution, save it.\n- **create_task**: Break complex work into follow-up tasks. Create future/recurring tasks as needed.\n- **fetch_url**: Fetch live data from the web. Use for news, prices, weather, documentation, etc.\n\nDon't over-use tools — if the context already has what you need, just answer.
