Hours 8am-5pm Monday-Saturday, closed\nSunday. Website: tribecabeverage.com\n`;\n\nexport const SYSTEM_PROMPT =\n `You are the after-hours chat assistant on tribecabeverage.com, the website for TriBeCa Beverage Company. The office is CLOSED right now — that is the whole reason you are answering instead of a person.\n\n${BUSINESS_PROFILE}\n\nYour job, in priority order:\n1. Answer the visitor's question if the profile above covers it.\n2. Get enough contact information that the office can follow up: a name, a phone number or email, and roughly where they are (town or ZIP).\n3. Set the right expectation — someone from the office will follow up the next business day (the office is open 8am-5pm Monday-Saturday, closed Sunday).\n\nStyle:\n- This is a small chat window. Keep replies to 2-4 short sentences. No markdown, no bullet lists, no headings, no emoji unless they use one first.\n- Warm and direct. Answer what was asked, then ask at most one thing back.\n- Ask for contact details naturally, once you've actually been helpful — not in your first message.\n\nHard rules — these matter more than being helpful:\n- Only quote prices that appear in the profile above. For anything without a listed price (name brands, filtration, dispenser cleaning, private label, orders over 8 bottles), say the office will confirm pricing. Never invent or estimate a number.\n- Never promise a specific delivery date, delivery window, or discount. The office confirms all scheduling.\n- You cannot place an order, change an existing order, process a payment, or cancel service. You take the details down and the office handles it. Say so plainly if asked.\n- If you don't know something, say you don't know and that the office will confirm. Do not guess.\n- If they are upset, ask for a human, or raise anything outside the profile above, give them the office number: 973-913-4568, open 8am-5pm Monday-Saturday.\n- Never claim to be a human. If asked, say you're an automated assistant and the office follows up in the morning.`;\n",[161],"cea14d3e-6069-4afe-b970-cf9def9673cf","agent.ts","df287cfa-a0a1-11f1-afef-1607ee4eb77e",4,["D",1787675251919],"import Anthropic from \"npm:@anthropic-ai/sdk\";\nimport { email } from \"https://esm.town/v/std/email\";\nimport { EFFORT, MAX_TOKENS, MODEL, SYSTEM_PROMPT } from \"./config.ts\";\nimport { getLead, isReachable, type Lead, saveLead, type Turn } from \"./store.ts\";\n\nlet _client: Anthropic | null = null;\nfunction client(): Anthropic {\n if (!_client) {\n const apiKey = Deno.env.get(\"ANTHROPIC_API_KEY\");\n if (!apiKey) throw new Error(\"ANTHROPIC_API_KEY is not set on this val\");\n _client = new Anthropic({ apiKey });\n }\n return _client;\n}\n\n/**\n * Stream the assistant's reply.

Click **Remix** to get your own copy.\n\n## Picking a starter\n\n| Starter | When to pick it |\n| --- | --- |\n| [`basic-html-starter`](https://www.val.town/x/templates/basic-html-starter) | Static HTML pages. Sprinkle of vanilla JS. No server-side rendering. |\n| [`hono-jsx-starter`](https://www.val.town/x/templates/hono-jsx-starter) | Dynamic server-rendered HTML with JSX. API routes. No React, no SPA. |\n| **[`react-hono-starter`](https://www.val.town/x/templates/react-hono-starter)** *(you're here)* | Client-side React SPA with a Hono API backend. |\n\n**Want to build UI?** Start writing React components in\n[`frontend/components/`](/frontend/components/). Import them into `App.tsx` and\nyou're good to go. Styling is [Twind](https://twind.style/) — just use Tailwind\nutility classes, zero config.\n\n**Want to add an API?** Add routes in [`index.ts`](/index.ts) (there's a\ncommented-out example). Fetch them from your React components.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts
(Hono server)\"]\n Hono -->|serves| HTML[\"root.tsx\"]\n HTML -->|loads| Entry[\"index.tsx\"]\n Entry -->|renders| App[\"App.tsx\"]\n App -->|renders| Counter[\"Counter.tsx\"]\n```\n\n## File structure\n\n```\nindex.ts ← Hono backend (serves frontend + API routes)\nfrontend/\n root.tsx ← HTML shell (stamps immutable asset URLs)\n index.tsx ← React entrypoint (mounts )\n favicon.svg ← App icon\n components/\n App.tsx ← Root component (layout + view source link)\n Counter.tsx ← Example component with state\n```\n\n## How it works\n\n1. **`index.ts`** is the HTTP entrypoint — a Hono server that serves the\n frontend and any API routes you add.\n2. **`frontend/root.tsx`** is the HTML shell — it loads Twind and stamps\n immutable asset URLs for the favicon and React entrypoint.\n3. **`frontend/index.tsx`** mounts the React app.\n4. **`frontend/components/App.tsx`** is the root layout — add new components\n alongside it.\n5. **`frontend/components/Counter.tsx`** is an example stateful component —\n replace it with your own!\n\n## Next steps\n\n- Add API routes in `index.ts`\n- Add new components in `frontend/components/`\n- Add a SQLite database — see the\n [React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) for\n a full-stack example with database, queries, and shared types\n\nTemplate updates and upgrade paths for existing remixes: [CHANGELOG.md](/CHANGELOG.md)\n",[174],"5518f1a0-f980-467d-85ce-59331b3e55d0","CHANGELOG.md","01a039bc-e9a8-70ef-b2b9-7551e658384c",["D",1787675076940],"# Changelog\n\n## 2026-07-30 — Immutable asset caching\n\nFrontend files are now served at version-addressed URLs\n(`/__immutable/45/frontend/index.tsx`) with\n`Cache-Control: public, max-age=31536000, immutable`, so repeat visits load the\nwhole client graph from the browser cache — roughly 3× faster (~665ms → ~157ms\nmeasured). Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
