blueprint-cloudflare-auth

blueprint-cloudflare-auth is a skill for Claude Code, Codex from receptron/mulmoterminal. It costs 23 tokens per session (434 once invoked), scanned A, original, MIT.

A Firebase Google sign-in setup that uses the local Auth emulator during development. An emulator is a local copy of a service used for testing instead of contacting the live service.

In plain words
What is it for?
It is for adding Google sign-in, using a redirect on mobile when needed, and testing what signed-in and signed-out users can read.
Why use it?
It gives the app a defined signed-out state and lets authentication and access rules be tested without relying on real user accounts or production data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

blueprint-cloudflare-auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Sign-in

A published Worker can be opened by anyone who has its URL. Read the spec's sign-in choice.

  • None: only what the spec says a visitor may see and do is reachable. Say so on the main screen's footer. test/auth.test.ts proves an operation the spec reserves (if any) is refused without a session.
  • One shared password: a sign-in screen; the password's PBKDF2 hash (Web Crypto, per-install salt) as a wrangler secret (.dev.vars locally, in .gitignore); a signed, HttpOnly, Secure, SameSite=Lax session cookie; every /api route except /api/health and sign-in refuses without it.
  • One account per person: a users table (PBKDF2 hash with a per-user salt), sign-in and sign-out, roles if the spec lists them, checked on the server for every route. If the spec says only a company's people may sign in, Cloudflare Access in front of the Worker is the simplest door: say so in .blueprint/open-questions.md.

test/auth.test.ts: a request without a session is refused, with one it passes; a wrong password is refused.

Done when the check passes: yarn build and yarn test succeed and test/ has the auth tests.

Always

  • Read .blueprint/spec.md first. It is the agreed specification; do not widen it.
  • When you need a decision, ask it through the blueprint question tool and stop. Do not guess.
  • Do not run git init: a new repository loses the folder's trust and the next unattended step stops at Claude Code's trust prompt. The user adds git themselves after the build if they want it.
  • Say you are done by stopping; the executor runs the check. Do not claim success yourself.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
