blueprint-cloudflare-api

blueprint-cloudflare-api is a skill for Claude Code, Codex from receptron/mulmoterminal. It costs 22 tokens per session (378 once invoked), scanned A, original, MIT.

A JSON API exposes the app's specified operations through web addresses under /api. JSON is a text format commonly used to send structured data between software systems.

In plain words
What is it for?
It adds one route per specified operation, validates inputs, returns clear 400 or 404 errors, blocks state changes from other origins, and tests valid and invalid requests.
Why use it?
It gives the interface a predictable, validated way to read and change data while rejecting bad requests and unsafe cross-site changes.

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-api 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 25d 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

API

  1. One route per operation in the spec's API table, in the Worker's /api/* handler.
  2. At the entry, before routing and before sign-in:
    • a POST / PUT / PATCH / DELETE whose Origin (or, without one, Referer) is not this Worker's own origin is refused with 403;
    • a JSON body is read once, and a malformed one is refused with 400 for every path. A Worker reads bodies per route by default, which leaves a malformed body to whatever the route does with it.
  3. Validate every body and parameter (zod is fine) and answer 400 with a message when it is wrong; 404 for a missing row. Every error reaches one handler that answers JSON without a stack trace.
  4. test/api.test.ts: every route in both directions — the valid request succeeds with the right body, an invalid one is refused with 400 — through SELF.fetch.

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