Muse connector starter

A small Cloudflare Worker that sits between Meta's Muse and the API you want Muse to use. Most APIs don't need one:
if yours takes a single key, Muse connects to it directly. Use this when the API needs more than one secret (Muse holds
one key) or you're adding your own logic. It gets you to one real call through Muse in about an hour.

Not affiliated with Meta.

What you get

• A Worker facade (worker/index.js): Muse sends one bearer token; the Worker checks it and calls your upstream
  API with the real key, which stays in the Worker's environment and never reaches Muse or a chat.
• One working call, GET /v1/status, that proves the bearer and the upstream key both work.
• openapi.yaml: that call described with bearer auth, ready to grow into your real API.
• CONNECT.md: a connect spec template (provider, hosts, auth scheme, where each key lives).
• SKILL.md: a skill template that teaches Muse when and how to call you, including confirming writes first.
• PROOF-CHECKLIST.md: what to show in a short video that proves the connector works end to end.

Hour one

cd worker
npm install
npx wrangler login                          # free Cloudflare account; Workers free tier needs no card
# edit wrangler.toml: [vars] UPSTREAM_BASE_URL = your provider's API base URL
npx wrangler secret put UPSTREAM_API_KEY    # your provider's real key; the Worker holds it
npx wrangler secret put BEARER_TOKEN        # make one up: openssl rand -hex 32
npx wrangler deploy                         # prints your Worker URL
node --test test.mjs                        # the Worker's own checks

Then tell Muse: connect to your Worker URL, authenticate with Authorization: Bearer <token>, and call
GET /v1/status. If it comes back ok: true with the upstream reachable, the wiring is done. A 401 means the bearer
is wrong; an unreachable upstream means UPSTREAM_BASE_URL or UPSTREAM_API_KEY is wrong.

The rules the Worker is built around

• One bearer for Muse. If the upstream needs several secrets, the Worker holds all of them.
• A long random bearer (at least 32 characters; the Worker refuses shorter). Add a Cloudflare rate-limiting rule on
  the Worker's route so nobody can hammer it or your upstream quota.
• Secrets only through wrangler secret put. Never in the repo, a prompt, or a chat.
