Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00278 | $0.00278 |
| Opus 5 | $0.00139 | $0.00139 |
| Sonnet 5 | $0.00056 | $0.00056 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
commit-messages 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 yesterday.
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
Commit messages
The commit message must use the current branch name as prefix, with any / replaced by -.
Format
<normalized-branch>: <short description>
[optional body]
- Prefix: current branch name, replacing
/with-. Example: branchfeature/292-github-action-rename→ prefixfeature-292-github-action-rename. - Description: imperative, lowercase, no trailing period. You may optionally include conventional type (
feat,fix,docs, etc.) in the description.
Examples
Branch feature-292-github-action-rename:
feature-292-github-action-rename: add concurrency and permissions to ci_checkfeature-292-github-action-rename: fix docs callouts (Info instead of Note/Tip)
Branch fix/123-docs-anchor (normalized to fix-123-docs-anchor):
fix-123-docs-anchor: remove invalid MDX heading anchors
When suggesting or writing a commit message, use the current branch with / replaced by - as the prefix. If you don't know the branch, tell the user to use their branch name as the prefix.
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.

commit-messages is a cursor rule published in the GitHub repository vypdev/copilot (2 stars, last pushed yesterday), licensed MIT. It adds 278 tokens to every session, about $0.0014 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
