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

no-co-author-in-commits 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 13d 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

No Co-Author Trailers in Commit Messages

Note: Do not add co-author or AI attribution info to commit messages in future work unless the user explicitly asks for it.

When drafting, generating, or composing a git commit message (including via generate-commit-message or before git commit):

  • Do not append Co-authored-by: lines or other co-author / AI attribution footers to the message.
  • Do not add Co-authored-by: Cursor or similar agent attribution.

Include only subject, body, and footers required by the project's commit-message requirement (e.g. Fixes #123, breaking-change notices). Add co-author trailers only if the user explicitly asks for them or a non-empty requirement from tod get-commit-message-requirement mandates them.

Remove injected co-author trailers

If a commit you just created still contains Co-authored-by: or other AI attribution footers (for example injected by the environment after git commit / git commit --amend):

  1. Verify the commit is yours from this conversation and has not been pushed.
  2. Rewrite the HEAD commit message to the intended text without those trailers (for example via git commit-tree + git reset --soft, or an equivalent rewrite that does not reintroduce the trailer).
  3. Confirm git log -1 --format='%B' has no Co-authored-by: / AI attribution lines before finishing.

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.
