commit_msg

A set of rules for writing consistent Git commit messages. Git commits are saved records of changes made to a code project.

In plain words
What is it for?
Labeling commits for new work, bug fixes, documentation, tests, configuration, database changes, and other updates.
Why use it?
It removes guesswork about which label and wording to use when recording a change.

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.

Made for: Cursor.

Per session 4 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 367 The whole file, excluding the scripts and references it only reads on demand.

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

commit_msg 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.

Origin

This is a copy

100% identical to commit_msg — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Please follow the following for commit message convention:

  • 🏗️ {msg} : initial first pass implementation
  • 🔨 {msg} : make feature changes to code, not fully tested
  • 🐛 {msg} : bugfix based on an initial user reported error/debugging, not fully tested
  • 📝 {msg} : writing/editing docs or ./cursor/rules (incl AGENT.md)
  • ✨ {msg} : code formatting/linting fix/cleanup. Only use when nothing has changed functionally.
  • ✅ {msg} : fetaure implemented, E2E tests written, tests passing
  • ⚙️ {msg} : configurations changed (not source code, e.g. .toml, .yaml files)
  • 👀 {msg} : logging/debugging prints/observability added/modified
  • 💽 {msg} : updates to DB schema/DB migrations
  • ⚠️ {msg} : non-reverting change

Please use multiple emojis for larger commits, to emphasize the size of the commits. For example:

  • 🏗️🏗️🏗️ {msg} : Multiple new files written (5+)
  • 🏗️🏗️ {msg} : A few new files written (3-5)
  • 🏗️ {msg} : 1-2 new files written
  • 🐛🐛🐛 {msg} : Large number of files modified to fix a bug (8+)
  • 🐛🐛 {msg} : Multiple files modified to fix a bug (4-7)
  • 🐛 {msg} : Few files modified to fix a bug (1-3)

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.
