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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00830 | $0.00830 |
| Opus 5.5 | $0.00332 | $0.00332 |
| Sonnet 5.5 | $0.00166 | $0.00166 |
| Haiku 4.5 | $0.00083 | $0.00083 |
Grade A, and why
mergewarden AGENTS.md 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Project
This repository implements MergeWarden, a deterministic CI firewall for AI-generated pull requests.
Non-Negotiable Principles
- Runtime analysis must not call LLMs by default.
- The GitHub Action must not execute PR-controlled code.
- The GitHub Action must eventually load
mergewarden.ymlfrom the PR base branch, not from the PR head branch. - All policy decisions must be explainable with deterministic evidence.
- Core analysis must be independent from GitHub APIs.
- Every rule must have fixture-based tests.
- Prefer small, pure functions.
- Use TypeScript strict mode.
- Use Zod for future config and contract validation.
- Use Vitest for tests.
- Do not add production dependencies without updating this file and explaining why.
Commands
- Install:
pnpm install - Typecheck:
pnpm typecheck - Test:
pnpm test - Lint:
pnpm lint - Build:
pnpm build - Browser regression:
pnpm build && node packages/web/scripts/browser-smoke.mjs(requires Chrome or Chromium; setCHROME_PATHoutside standard locations)
Architecture
packages/core: pure analysis engine with no GitHub API dependency. It uses@noble/hashesfor SHA-256 so finding IDs and policy digests stay identical in Node.js and browsers without a Node crypto shim.packages/github: private API-only pull-request collection package; depends on@mergewarden/corethrough the workspace and exposes transport ports used by the Action and CLI. It adds no third-party production dependency.packages/web: private static browser package; uses the shared core and GitHub packages to scan public PRs without a backend, token, checkout, or telemetrypackages/cli: publicmergewardenCLI; uses the private core and GitHub packages at build time, then bundles every runtime dependency into the published executable so npm metadata has no private orworkspace:*runtime dependencypackages/action: API-only GitHub Action wrapper package; depends on the private core and GitHub packages through the workspace and on the official@actions/core/@actions/githubtoolkit only to read pull request data through GitHub APIs, write bounded reports, set outputs, update the job summary, and optionally upsert a marked PR report comment without checking out or executing PR-controlled code
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.
