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

rustwright 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.

Repository Instructions

Public boundary

Treat every tracked file, commit, branch name, and review artifact as if it will be publicly visible. This repository is the source of truth; a separate, reviewed sync republishes approved content to a public mirror, so every change merged here is the last gate before it can become public.

  • Never add credentials, auth headers, customer data, private URLs, personal filesystem paths, employee email addresses, internal ticket identifiers, or private host/network topology.
  • Do not name private repositories, packages, modules, services, or operational incidents. Use neutral placeholders such as <organization>, <repository>, <remote-host>, and <source-checkout> in public examples.
  • Keep integration tools that import or inspect private code in the private repository. Public tools must require explicit user-supplied paths and must not default to sibling checkouts.
  • Keep raw benchmark data, terminal output, HAR files, environment files, and generated reports untracked. Publish only reviewed, reproducible summaries; never let a headline number rest on demo-grade or otherwise irreproducible data.
  • Use a GitHub noreply address for commit author and committer identities. Automation co-author trailers must likewise use a provider noreply address (for example [email protected]), never a personal or corporate mailbox. Never rewrite or force-push shared history without explicit owner approval, and never use git push --all.

Before committing, inspect the staged diff for disclosure risks.

Pull-request review

Development checkouts push only to this repository — there is no direct push to the public mirror; the reviewed sync is the only path content takes to become public. Every pull request opened here is reviewed automatically by .github/workflows/claude-code-review.yml, which loads its prompt from .github/prompts/code-review.md on the pull request's base branch (so an untrusted pull request cannot alter its own review) and posts a single comment.

Changes

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.
