A small camera preview sits in\nthe bottom-right corner; when your face is detected close and confident enough,\na voice session starts automatically and the AI **greets you first by name**.\nThe call stays open until you end it (the talk button) or say \"goodbye\" (the AI\nhangs up itself).\n\nThe whole sidebar is now a **hamburger-summoned drawer at every screen width**\n(no permanent sidebar) — the face-tracking sliders live in it.\n\n## Face-triggered sessions\n\n- A persistent camera+mic stream feeds **MediaPipe FaceDetector**\n (`blaze_face_short_range`). The bottom-right PiP draws the detection box and a\n live confidence / face-size readout.\n- Two sliders (in the drawer) gate when a call fires: **min confidence** and\n **min closeness** (face size as % of frame — bigger = must be nearer). A call\n auto-starts on the rising edge of crossing *both* thresholds, only when\n logged in and idle, and re-arms after your face leaves the frame.\n- The AI can retune the gate by voice via **`set_face_tuning`** (\"you're too\n sensitive\", \"wait until I'm closer\"), and hang up via **`end_call`** when you\n say goodbye.\n- The mic is shared from the camera stream (cloned for the call), so there's a\n single permission prompt on load. Greeting audio may be blocked by the browser\n until your first interaction — clicking anywhere once unlocks it.\n\n## Per-user memory (one ledger, pinned = always-loaded)\n\nEach logged-in user gets a private, append-only \"second brain\" (SQLite, scoped by\nVal Town handle) so calls don't start from scratch. It's **one unified ledger**:\n\n- **Subjects** (projects, objects, topics — and **`me`** for the user themselves)\n each hold append-only **facts**; **edges** relate subjects.\n- A fact is **pinned** (auto-loads into the system prompt every call — the\n \"never start from scratch\" layer) or **unpinned** (recalled on demand). The\n pin flag is the single determiner of \"always-loaded vs on-demand\".\n- **Identity is not stored** — the user's name, handle, and email are pulled\n from their Val Town login (`/v2/me`) and injected into the prompt each call.\n\nTools (write only when asked): `remember_about_me` (pinned fact under `me`),\n`record_fact(subject_id, assertion, pin?)`, `recall_subject`, `recall_recent`,\n`link_subjects`, `retract_fact`. The agent is instructed to be conservative —\nwrite only on request, pin only for \"always remember…\", never dump memory\nunprompted.\n\nThe **🧠 Memory** page (`/memory`) is the dashboard: a \"📌 Always loaded\"\npanel, per-fact pin/unpin, subject timelines, manual entry, and the **mindmap**\n(force-graph of subjects + relations). Backend + API live in `routes/memory.ts`.\n\n## What it does\n\n- **Talk to edit** — describe a change (\"add a dark mode toggle\", \"make the\n header bigger\") and the AI edits the val's files, then reloads the preview.\n- **Open any val** — say _\"open my X\"_, **type a val name** in the box (a bare\n name resolves to your handle; `handle/name` and pasted val.town URLs work\n too), click one from **Recent vals**, or seed it with `?val=handle/name`.\n- **Create from scratch** — the **✨ Create a new val** button (or just asking\n the AI) spins up a minimal HTTP val with a starter page and loads it, so you\n have an instant canvas to iterate on.\n- **Newcomer-friendly** — the AI is briefed to assume the person may be brand\n new to this _and_ to Val Town, orient them in plain language, and offer a\n concrete first thing to build.\n- **Scenes & choreography** — vals can ship a `CHOREOGRAPHY.md`; the AI triggers\n pre-built overlays via the `set_scene` tool and can drive slideshows.\n\n## How it works\n\n1. The browser logs in with **Val Town OAuth** and opens a WebRTC mic\n connection.\n2. `POST /rtc` negotiates an **OpenAI Realtime** session, seeded with the\n official Townie system prompt plus a Studio-specific addendum, and attaches\n the signed-in user's **Val Town MCP** token so the AI can read/write their\n vals (`routes/agent.ts`).\n3. The AI calls **function tools** handled in the browser — `load_val`,\n `navigate_page`, `reload_site`, `set_scene`, `slide_next/prev/goto`,\n `set_face_tuning`, `end_call` — and the `val_town_mcp` tools for file edits.\n4. The preview iframe reloads **on demand** (via the `reload_site` tool or the\n \"↻ Reload site\" button) — auto-refresh polling is intentionally disabled.\n\n## Running your own / OpenAI key\n\nThe deployed studio runs on the owner's `OPENAI_API_KEY`. If that key is ever\nrejected or out of quota, the UI shows a **\"remix this val & add your own\n`OPENAI_API_KEY`\"** prompt instead of a cryptic error.\n\nTo run your own copy:\n\n1. **Remix** this val (the link in the error, or the Remix button on the val\n page).\n2. Set **`OPENAI_API_KEY`** (an OpenAI key with Realtime API access) in the\n remixed val's environment variable settings.\n3. Open the val's HTTP endpoint and start talking.\n\n## Environment variables\n\n- **`OPENAI_API_KEY`** _(required)_ — OpenAI key with Realtime API access. The\n app no longer crashes at startup when this is missing; instead `/rtc` returns\n a structured error the UI turns into the remix prompt above.\n\n## API endpoints\n\n- `GET /` — serves the studio (`frontend/studio.html`)\n- `POST /rtc?val=` — create a new WebRTC Realtime session (`val` is\n optional). Returns `{ code: \"openai\" | \"upstream\", ... }` on failure.\n- `POST /observer/:callId` — internal server-side session control (fire-and-forget)\n- `GET /me` — current login state\n- `GET /auth/token` — OAuth token handoff (rarely needed; the studio is\n same-origin)\n- `GET /source` — 302-redirects to this val's page on Val Town (used by the\n remix link, so it's correct even for remixed copies)\n- `GET /api/resolve-val?val=` — resolve a val to its live HTTP URL\n- `GET /api/recent-vals` — the signed-in user's most recent vals\n- `POST /api/create-val` — create a new public val with a minimal HTTP starter\n\n## Project structure\n\n```\n├── main.tsx # Entrypoint: OAuth middleware, route mounting, /me, /source, serves studio\n├── frontend/\n│ └── studio.html # The Voice Edit Studio UI (WebRTC, waveform, sidebar, load/create)\n└── routes/\n ├── agent.ts # Realtime session config: tools + Townie prompt + Studio addendum\n ├── rtc.ts # WebRTC session setup + OpenAI-error classification\n ├── observer.ts # Server-side session control (WebSocket to OpenAI)\n ├── api.ts # /api: resolve-val, recent-vals, create-val\n └── utils.ts # Realtime API URL/header helpers + hasOpenAIKey()\n```\n\nOther files (`routes/sip.ts`, `frontend/index.html`, `frontend/widget.html`,\n`frontend/sdk.js`, `sdk.ts`, `oauth-test.tsx`) are inherited from the\n`hello-realtime` base this was built on and are **not mounted** by `main.tsx`.\n\n## Notes\n\n- **If the AI says it can't edit files**, the Val Town OAuth token has gone\n stale — **log out and back in** from the sidebar to refresh it.\n- **The preview does not auto-refresh** — the AI reloads it after finishing\n edits, or you can hit \"↻ Reload site\".\n",[176],"0f29e68a-5d1f-11f1-bc69-1607ee4eb77e","routes","019e7f4e-f0e9-72ce-b45f-c857c83d866b",["D",1780252340388],"directory",[184],"0f291296-5d1f-11f1-bc69-1607ee4eb77e","frontend","019e7f4e-f0e9-72ce-b45f-ae5bf3b8c0b0",["D",1780252340388],[190],"pulls","branches","forks","envVars",{"_201":203,"_204":155},"connections",{"_201":62,"_202":62},"count","unfilledCount",2,"emptyCount",{"_42":189,"_32":190,"_30":191,"_154":-5,"_40":41,"_39":155,"_156":25,"_37":331,"_13":62,"_33":187,"_35":-5,"_24":48,"_159":-5,"_224":332,"_27":333},{"_42":324,"_32":325,"_30":326,"_154":191,"_40":41,"_39":155,"_156":25,"_37":327,"_13":62,"_33":20,"_35":328,"_24":48,"_159":-5,"_224":329,"_27":330},{"_42":315,"_32":316,"_30":317,"_154":191,"_40":41,"_39":318,"_156":25,"_37":319,"_13":320,"_33":20,"_35":321,"_24":48,"_159":-5,"_224":322,"_27":323},{"_42":308,"_32":309,"_30":310,"_154":191,"_40":41,"_39":155,"_156":25,"_37":311,"_13":62,"_33":34,"_35":312,"_24":48,"_159":-5,"_224":313,"_27":314},{"_42":299,"_32":300,"_30":301,"_154":191,"_40":41,"_39":302,"_156":48,"_37":303,"_13":304,"_33":20,"_35":305,"_24":48,"_159":-5,"_224":306,"_27":307},{"_42":292,"_32":293,"_30":294,"_154":191,"_40":41,"_39":155,"_156":25,"_37":295,"_13":62,"_33":20,"_35":296,"_24":48,"_159":-5,"_224":297,"_27":298},{"_42":183,"_32":184,"_30":185,"_154":-5,"_40":41,"_39":155,"_156":25,"_37":289,"_13":62,"_33":187,"_35":-5,"_24":48,"_159":-5,"_224":290,"_27":291},{"_42":280,"_32":281,"_30":282,"_154":185,"_40":41,"_39":283,"_156":25,"_37":284,"_13":285,"_33":34,"_35":286,"_24":48,"_159":-5,"_224":287,"_27":288},{"_42":273,"_32":274,"_30":275,"_154":185,"_40":41,"_39":155,"_156":25,"_37":276,"_13":62,"_33":34,"_35":277,"_24":48,"_159":-5,"_224":278,"_27":279},{"_42":265,"_32":266,"_30":267,"_154":185,"_40":41,"_39":268,"_156":25,"_37":269,"_13":155,"_33":34,"_35":270,"_24":48,"_159":-5,"_224":271,"_27":272},{"_42":258,"_32":259,"_30":260,"_154":185,"_40":41,"_39":155,"_156":25,"_37":261,"_13":62,"_33":34,"_35":262,"_24":48,"_159":-5,"_224":263,"_27":264},{"_42":250,"_32":251,"_30":252,"_154":185,"_40":41,"_39":253,"_156":48,"_37":254,"_13":155,"_33":34,"_35":255,"_24":48,"_159":-5,"_224":256,"_27":257},{"_42":243,"_32":244,"_30":245,"_154":185,"_40":41,"_39":155,"_156":25,"_37":246,"_13":62,"_33":34,"_35":247,"_24":48,"_159":-5,"_224":248,"_27":249},{"_42":236,"_32":237,"_30":238,"_154":185,"_40":41,"_39":155,"_156":25,"_37":239,"_13":62,"_33":34,"_35":240,"_24":48,"_159":-5,"_224":241,"_27":242},{"_42":175,"_32":176,"_30":177,"_154":-5,"_40":41,"_39":178,"_156":25,"_37":233,"_13":180,"_33":20,"_35":181,"_24":48,"_159":-5,"_224":234,"_27":235},{"_42":168,"_32":169,"_30":57,"_154":-5,"_40":41,"_39":170,"_156":25,"_37":230,"_13":172,"_33":165,"_35":173,"_24":48,"_159":-5,"_224":231,"_27":232},{"_42":161,"_32":162,"_30":163,"_154":-5,"_40":41,"_39":155,"_156":25,"_37":227,"_13":62,"_33":165,"_35":166,"_24":48,"_159":-5,"_224":228,"_27":229},{"_42":151,"_32":152,"_30":153,"_154":-5,"_40":41,"_39":155,"_156":25,"_37":223,"_13":62,"_33":34,"_35":158,"_24":48,"_159":-5,"_224":225,"_27":226},["D",1780252340388],"children",[],[152],["D",1780252340388],[],[162],["D",1780254254718],[],[169],["D",1780255166884],[],[176],"0f29d244-5d1f-11f1-bc69-1607ee4eb77e","utils.ts","019e7f4e-f0e9-72ce-b45f-c71bfdc261f2",["D",1780252340388],"const REALTIME_BASE_URL = \"https://api.openai.com/v1/realtime\";\nconst OPENAI_API_KEY = Deno.env.get(\"OPENAI_API_KEY\");\n\n// Whether an OpenAI key is configured on this deployment.

The user sees the *deployed page* of a single val in an iframe on the left and talks to you out loud. Everything above about working with Val Town vals still applies — you have the **val_town_mcp** tools (\\`list_files\\`, \\`read_file\\`, \\`update_file\\`, \\`create_file\\`, \\`create_val\\`, \\`get_val_detail\\`, etc.). Always pass the val identifier as the \\`val\\` argument. In addition, this workspace gives you these control tools:\n\n- **load_val(val)** — swap which val's deployed page is shown in the iframe. Pass a \"handle/name\" identifier. Use for \"open my X\", \"show Y\", \"switch to Z\".\n- **navigate_page(path)** — keep the *same* val loaded but point the iframe at a different route within it (e.g. \\`/forklift\\` or \\`/\\`). A bare slug (\"forklift\") is accepted. Use for \"go to the X page\", \"next/previous example\", \"back to the home/gallery\". This is NOT for switching vals — use \\`load_val\\` for that.\n- **slide_next / slide_prev / slide_goto(index)** — if the loaded val is a slideshow (it listens for \\`slideshow:next/prev/goto\\` postMessage events), drive it. Safe no-op on vals that don't listen.\n- **reload_site** — reload the iframe to show your latest edits. The preview does not auto-refresh.\n- **set_scene(scene)** — trigger a pre-built overlay/modal on the loaded page without reloading (see the Scenes guide below). \\`set_scene(\"\")\\` closes it.\n\n## Choreography & scenes\n\nSome vals ship a **\\`CHOREOGRAPHY.md\\`** at their root — director's notes listing the val's pages, the \\`set_scene\\` overlays you can trigger, and a loose suggested flow. **When you load a val, read its CHOREOGRAPHY.md once** (e.g. \\`read_file(\"dcm31/design-gallery\", \"CHOREOGRAPHY.md\")\\`) if it has one, and let it make you a better host — but keep everything **spontaneous and natural**: improvise, follow the user's lead, and never recite the notes or announce that you're reading them. Trigger a page's overlays with \\`set_scene(name)\\` (names live in that file); \\`set_scene(\"\")\\` closes them. \\`dcm31/design-gallery\\` is the main showcase and has a full CHOREOGRAPHY.md.\n\n## Studio rules\n- ${\n username\n ? `The user's Val Town handle is **${username}**. When they say \"open foo\" without an owner, default to \\`load_val(\"${username}/foo\")\\`. If they say \"Steve's val foo\", use \\`load_val(\"stevekrouse/foo\")\\`.`\n : `When the user names a val without an owner, assume it's theirs.`\n }\n- The studio can only display vals that have an **HTTP file**. When creating a new val to show, call \\`create_val\\` with \\`initialFile.fileType: \"http\"\\` (a minimal Hono app exporting \\`app.fetch\\`), then \\`load_val\\` it. Don't pass a \\`description\\` of 64+ chars (the validator rejects it). If \\`load_val\\` says \"no HTTP file\", add one via \\`create_file\\` with \\`fileType: \"http\"\\` and retry.\n- The preview does **not** auto-refresh. When you've finished editing (all file writes for this request are done), call **reload_site** once so the user sees the new version. Don't reload after every individual file — batch the edits, then reload at the end. The user can also hit the \"Reload site\" button themselves.\n- **Be terse — this is voice, and the user can see the page.** Confirm in one short sentence (\"Updated main.tsx — added the button.\" / \"Created and loaded ${\n username || \"your-handle\"\n }/foo.\"). Don't read code aloud unless asked. Before a non-trivial change, say in one line what you'll do.\n- Treat the user as the val's owner.\n- ${\n initialVal\n ? `The val currently loaded in the studio is: **${initialVal}**.`\n : `No val is loaded yet. If the user asks to edit something, either open one of their vals with \\`load_val\\` or offer to create a fresh one — don't just ask \"which val?\" and stop.`\n }\n\n## Assume the person might be brand new — to this, and to Val Town\n\nMany people here are **complete newcomers**. They may have clicked a link, signed up moments ago, and have *no idea* what this is, what a \"val\" is, or what Val Town does. Some have never written a line of code. **Never assume prior knowledge.** Your job is to make them feel like building something is easy and fun, starting from zero.\n\n- **Open by orienting them, briefly, only if they seem lost** (they go quiet, say \"what is this?\", \"how does this work?\", \"I don't know what to do\"). One or two warm sentences, plain language, no jargon:\n > \"This is a place where you can build little websites and apps just by talking to me — I write the code, and it goes live instantly on the page to your left. Want to make something? Tell me an idea, even a rough one, and I'll start.\"\n- **If they ask what Val Town is:** it's a website where you can create and run small web apps, sites, and automations in the cloud — nothing to install, no setup, and whatever you make gets a real live link you can share. A **\"val\"** is just one of those projects — the thing showing in the panel on the left.\n- **Offer a concrete first step instead of an open-ended question.** Newcomers freeze on \"what do you want to build?\" Suggest 2–3 tiny, delightful options: \"a personal homepage\", \"a countdown to your birthday\", \"a tip calculator\", \"a page that tells a dad joke\". Then **just build it** — \\`create_val\\` (with \\`initialFile.fileType: \"http\"\\`), \\`load_val\\` it, and show them.\n- **Translate, don't lecture.** Avoid \"deploy\", \"endpoint\", \"HTTP handler\", \"Deno\", \"repo\", \"commit\". Say \"it's live\", \"your page\", \"the link\", \"the code\". Only go technical if *they* do.\n- **Narrate lightly so the magic is visible.** \"Okay — making you a page now… done, take a look on the left. Want it a different color?\" Keep it to a sentence; they can see the result.\n- **Never make them feel behind.** No \"as you probably know\", no assuming they understand a term. Celebrate small wins.\n- They don't need to type anything or learn commands — talking is enough. (They *can* also type a val name in the box on the page, or click **✨ Create a new val**, but you can do all of that for them by voice.)\n\n## Face-triggered sessions (this deployment)\n\nThis studio watches the user's webcam with on-device face detection. **This session was started automatically the moment their face was detected close and confident enough** — they did not click anything. So:\n\n- **You speak first.** Open with a short, warm, spontaneous greeting${\n username\n ? `, by name — the person is **${username}** (use just their first name, e.g. \"Hey ${\n username.split(/[^A-Za-z]/)[0] || username\n }!\").`\n : ` (a friendly hello; you don't know their name yet).`\n } One sentence, then invite them to build something. Don't explain that a camera or face detection started the call unless they ask.\n- **Ending the call:** when the user says goodbye / bye / see you / talk later / \"I'm done\", give a brief one-line sign-off and then call **end_call**. Keep the session open otherwise — they'll end it by voice or with the on-screen button.\n- **Tuning the trigger:** if they say things like \"you're too sensitive\", \"wait until I'm closer\", \"trigger from farther away\", \"be more eager to greet me\", call **set_face_tuning** (relative nudges or absolute values). Confirm in a few words.\n\n## Long-term memory (per user) — one ledger, use it sparingly\n\nThere is ONE memory: **subjects** (projects, objects, topics — and **'me'** for the user themselves) each holding append-only **facts**. A fact is either:\n- **Pinned** → it auto-loads into your prompt every call (see \"Always-loaded memory\" above if any exist). This is the \"never start from scratch\" layer.\n- **Unpinned** → recalled on demand.\n\nYou already know the user's **name, handle, and email from their login** (see \"Who you're talking to\") — never store those.\n\nTools: **remember_about_me(text)** (shortcut: a pinned fact under 'me' — for lasting personal preferences); **record_fact(subject_id, assertion_text, pin?)** (pin=true only for \"always remember…\" type requests); **recall_subject(subject_id)** / **recall_recent()** to read; **link_subjects(...)** to relate subjects in the mindmap; **retract_fact(fact_id, reason)** to fix a mistake.\n\n**Be conservative — this is the user's brain, not a scratchpad:**\n- **Only WRITE when asked** (\"remember that…\", \"note this\", \"always keep in mind…\", \"connect X to Y\"). Never record facts reflexively. Confirm in a few words when you do (\"Got it — pinned that.\").\n- **Decide pin vs not by their words:** \"always remember / from now on / keep in mind\" → pin=true; a plain \"remember that X about Y\" → unpinned under subject Y.\n- **Reading is cheap:** pinned facts load automatically; call recall_subject / recall_recent when relevant or asked. Don't dump memory unprompted.\n- They can see, pin/unpin, and edit everything (including the mindmap) on the **Memory** page (🧠 in the menu).`;\n}\n\nfunction buildSystemPrompt(initialVal?: string, username?: string): string {\n return `${towniePrompt}${studioAddendum(initialVal, username)}`;\n}\n\n// Builds the declarative session config. accessToken is required to give the\n// AI val.town MCP access; initialVal seeds the system prompt.

Voice Edit SDK

\n One line of code, and any Val Town val gets a little green circle in\n the corner that lets you voice-edit its source.\n

\n\n

Usage — Hono

Two lines added to any val you own. The val identifier is auto-detected:

import { voiceEdit } from \"https://esm.town/v/dcm31/voice-edit-sdk/sdk.ts\";\napp.use(voiceEdit());

\n\n

Usage — plain fetch handler

import { wrapFetch } from \"https://esm.town/v/dcm31/voice-edit-sdk/sdk.ts\";\nexport default wrapFetch(myHandler);

\n\n

Or: plain HTML snippet

If you'd rather paste a script tag into your HTML:

<script src=\"/sdk.js\" data-val=\"handle/name\" defer></script>

\n\n

What it does

\n Adds a small green circle in the bottom-right corner. Click to expand\n a login card, sign in with Val Town, then click again to start talking.\n The AI uses your Val Town MCP token to read and edit the host val's\n source — say things like \"add a button that says hello\" or\n \"in main.tsx, change the title to 'Welcome'\". Refresh the\n page to see edits live.\n

\n\n

How it works

\n The script injects an <iframe> pointing at this\n val's /widget page.\n
\n The widget runs same-origin, so OAuth, WebRTC, and audio all live\n inside it — no cross-origin cookie or CORS issues.\n
\n On connect, the OpenAI Realtime API is given the Val Town MCP server\n plus your access token, scoped to the val you specified.\n
\n The circle pulses with the AI's voice volume via an\n AnalyserNode on the remote audio track.\n
