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

pn-no-cursor-commit-trailers 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 29d 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 Cursor commit trailers or authorship

When you create commits, edit messages, or suggest git commit text (including multi-line bodies):

  • Do not include Made-with: Cursor or any line starting with Made-with:.
  • Do not add Co-authored-by: Cursor <[email protected]> or similar IDE-generated Co-authored-by trailers.
  • Do not set Author or Committer to Cursor Agent, cursoragent, [email protected], or [email protected]. Commit as the repository user.
  • If the tool or environment inserts those lines or that identity, remove them before the commit is finalized.

Prefer this repo’s prepare-commit-msg hook (git config core.hooksPath .githooks). See docs/commits.md for CI and contributor notes.

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.
