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-firebase-deploy-dev 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 12d 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

Publish to dev

  1. yarn build, then give this build an id and ship it with the site: node -e 'console.log(require("crypto").randomUUID())' > .blueprint/build-id && cp .blueprint/build-id dist/blueprint-build.txt, then firebase deploy --project dev. The check compares the served id with .blueprint/build-id, so it proves THIS build is live. Git is not needed for this.
  2. Tell the user the URL (https://<dev-project-id>.web.app) and what to try there.

Never deploy to prod in this step.

Done when the check passes: the dev site serves the id this deploy wrote to .blueprint/build-id, serves a web app config at /__/firebase/init.json, has Google sign-in switched on, and the page renders text in headless Chrome (a blank page fails).

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.
  • Never enable billing, deploy to production, delete data or handle a credential unless this step's gates say the user approved exactly that.
  • 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.
