Val Town infers a file's val-type from\n> reserved name infixes (`http`, `cron`, `email`, …), so the mini-framework lives in `core/api.ts`,\n> **not** `core/http.ts`.\n\n---\n\n## Auth model (per-customer key, cname in the URL)\n\nThe customer (`cname`) is the first path segment: `/c//`. Auth is scoped to that cname:\n\n- Send the key as `Authorization: Bearer ` (or `X-API-Key: `).\n- Each customer is a [Hono](https://hono.dev) sub-app mounted at `/c/`. Its middleware (bound to\n that `id`) calls `authenticate(req, cname)` — loads ``'s config and compares the bearer\n token to the stored key in constant time. Rejected when the customer is unconfigured/disabled\n (403) or the key is missing/wrong (401). The customer module \"owns\" its name + validation by\n construction. A second middleware records every call (success or denied) to the call log.\n- **Admin UI** is gated by Val Town OAuth — only usernames in `ADMIN_USERS` get in.\n\nKeys are minted in the admin UI (generated on first save, rotatable), stored in SQLite, and shown in\nthe UI so you can copy them. They carry a readable `utt__` prefix, but routing no\nlonger depends on the prefix — the URL's `cname` is authoritative.\n\n---\n\n## Customers & functions\n\nEverything served over the API is a **function** — a `Fn = (ctx) => Response`. Functions are\nregistered per customer and exposed at `/c//`. A function may invoke an agent or not; the\nAPI doesn't distinguish. A customer's `index.ts` declares its functions via\n`defineCustomer({ id, label, fns })`; the factory builds a Hono sub-app, wiring auth + call-logging\nmiddleware (bound to that `id`) and a route per function. Routing, methods, and errors are Hono's\njob — there is no hand-rolled path parsing.\n\nEach customer is a folder under `backend/customers/`. To add one:\n\n1. Copy `backend/customers/jjs/` to `backend/customers//` and edit the id + label.\n2. Register it in `backend/customers/registry.ts`.\n3. In the admin UI, generate + enable its key.\n\nCurrent functions:\n\n- **`echo`** (builtin, all customers) — reflects method, query, and body back to the caller.\n- **`get-a-new-quote`** (`ttai`) — invokes a LangChain + OpenAI agent that invents a fresh, original\n quote. Output is schema-constrained (`quote`, `author`, `theme`) via structured output. Optional\n JSON body `{ \"theme\": \"courage\" }`; otherwise a theme is picked for you.\n- **`get-customer-info`** (`jjs`) — deterministic Shopify Admin read (no LLM). Body with at least\n one of `customer_id` / `email` / `phone` → profile, pending orders, abandoned checkouts.\n- **`shopify-agent`** (`jjs`) — abandoned-cart sidekick. Body `{ customer_id, cart_id, prompt }`;\n the agent reads store state and adds/removes cart lines per the prompt, returning a summary +\n actions.\n\n**Add a function** — drop a file in `backend/customers//` exporting an `Fn`, then add it to that\ncustomer's `fns` map. Reusable functions (like `echo`) live in `backend/customers/builtins.ts`.\n\n**Invoke an agent from a function** — see `customers/ttai/get-a-new-quote.ts` or\n`customers/jjs/shopify-agent.ts`: each adapts the request into an `AgentCtx` and calls `runAgent()`.\nThe runtime (`agents/runtime.ts`) owns all LLM wiring, so agents stay declarative; add new agents\nunder `backend/agents/`. Tool-using agents reuse `agents/tool-loop.ts` (model→tools→model).\n\n**Add an integration** — create `backend/integrations//` with a customer-agnostic client +\nhelpers (see `shopify/`). Resolve per-customer credentials from `__*` env so adding\na merchant is config-only.\n\n---\n\n## Environment variables\n\nSet these in the **Val Town UI sidebar** — never in code (`Deno.env.set()` is a no-op on Val Town).\nOur own vars are read through `env()` in `backend/core/shared.ts`; declared in `val.yml`.\n`OAUTH_STATE_ENCRYPTION_KEY` is read directly by the Val Town OAuth middleware (`std/oauth`).\n\n| Var | Status | Used by | Purpose |\n| ------------------------------ | ----------- | --------------------------------- | ------------------------------------------------------------ |\n| `ADMIN_USERS` | required | `core/auth.ts` (`/admin`) | Comma-separated Val Town usernames allowed into the admin |\n| `OPENAI_API_KEY` | required | `agents/runtime.ts` | OpenAI key for the LangChain agents (agent-backed functions) |\n| `OAUTH_STATE_ENCRYPTION_KEY` | recommended | `std/oauth` via `withValTownAuth` | AES-GCM key material that encrypts the admin session cookie |\n| `JJS_SHOPIFY_SHOP` | optional | `integrations/shopify` (`jjs`) | jjs store hostname, e.g. `jhaji.myshopify.com` (no scheme) |\n| `JJS_SHOPIFY_CLIENT_ID` | optional | `integrations/shopify/token.ts` | jjs Dev Dashboard app client id — mints Admin tokens |\n| `JJS_SHOPIFY_CLIENT_SECRET` | optional | `integrations/shopify/token.ts` | jjs Dev Dashboard app client secret |\n| `JJS_SHOPIFY_STOREFRONT_TOKEN` | optional | `integrations/shopify` (`jjs`) | jjs Storefront API token — cart mutations |\n\nNotes:\n\n- `ADMIN_USERS` example: `alice,bob`. Empty/unset ⇒ nobody can reach `/admin` (everyone is denied).\n- `OPENAI_API_KEY` only matters for agents. Unset ⇒ agent-backed functions return **503**; plain\n functions (e.g. `echo`) still work.\n- `JJS_SHOPIFY_*` only matter for the `jjs` Shopify functions. The integration reads\n `_SHOPIFY_*` (uppercased id), so a new merchant is config-only. Unset ⇒ those functions\n return **503**. Storefront token is needed only for cart mutations (`shopify-agent`).\n- **Admin auth (Shopify Dev Dashboard):** set `CLIENT_ID` + `CLIENT_SECRET` from the app's Settings\n page. `token.ts` exchanges them for a ~24h Admin token via the client-credentials grant and caches\n it. See [Admin & Storefront API → Generate tokens](../../../docs/wiki/integrations/shopify/admin-api.md).\n- `OAUTH_STATE_ENCRYPTION_KEY` — if unset, the middleware auto-generates a key and stores it in Val\n Town blob storage per redirect URI. That works, but **set it explicitly** so admin sessions\n survive redeploys and work on self-hosted runtimes. Any high-entropy string works (it's SHA-256'd\n to a 256-bit AES key); generate one with:\n\n```bash\n# generate a 32-byte base64 key (macOS: append `| pbcopy` to copy it)\nopenssl rand -base64 32\n```\n\nThen paste the value into the val's **Environment Variables** sidebar as\n`OAUTH_STATE_ENCRYPTION_KEY`. `vt` does not manage env vars — they must be set in the Val Town UI.\n\n---\n\n## Local → Val Town with `vt`\n\nRun from **inside this directory** (`exp/vals/uAgents/`).\n\n```bash\nvt status # review what changed\nvt push # push (forceful — revert via the Val Town website if needed)\nvt browse # open the deployed val\n```\n\nFirst push of a brand-new val: `vt create uAgents .`. To link an existing remote val, `vt clone` it\nto a temp dir and move its `.vt/` folder next to this code. After pushing, set the\n[environment variables](#environment-variables) in the Val Town UI.\n\n---\n\n## Try it\n\n```bash\n# 1. In /admin, generate + enable a key for \"ttai\", then:\nexport VT_TTAI_APP_TOKEN=\"generate-from-admin-ui\"\nexport VT_JJS_APP_TOKEN=\"generate-from-admin-ui\"\n\n# plain function (echo)\ncurl -X POST https://uagents.val.run/c/ttai/echo \\\n -H \"Authorization: Bearer $VT_TTAI_APP_TOKEN\" \\\n -H \"Content-Type: application/json\" -d '{\"hi\":\"there\"}'\n\n# agent-backed function (fresh quote)\ncurl -X POST https://uagents.val.run/c/ttai/get-a-new-quote \\\n -H \"Authorization: Bearer $VT_TTAI_APP_TOKEN\" \\\n -H \"Content-Type: application/json\" -d '{\"theme\":\"craftsmanship\"}'\n```\n\nNegative paths (auth + routing) — handy as a quick smoke test:\n\n```bash\nBASE=https://uagents.val.run\n\n# missing key → 401\ncurl -s -o /dev/null -w '%{http_code}\\n' -X POST \"$BASE/c/ttai/echo\" -d '{}'\n\n# wrong key → 401\ncurl -s -o /dev/null -w '%{http_code}\\n' -X POST \"$BASE/c/ttai/echo\" \\\n -H \"Authorization: Bearer nope\" -d '{}'\n\n# unknown customer → 404\ncurl -s -o /dev/null -w '%{http_code}\\n' -X POST \"$BASE/c/nope/echo\" \\\n -H \"Authorization: Bearer $VT_TTAI_APP_TOKEN\" -d '{}'\n\n# unknown function on a real customer → 404\ncurl -s -o /dev/null -w '%{http_code}\\n' -X POST \"$BASE/c/ttai/nope\" \\\n -H \"Authorization: Bearer $VT_TTAI_APP_TOKEN\" -d
