git-commit-standards

A Git rule that checks whether commit messages follow a shared format. Git is a tool developers use to track changes to code.

In plain words
What is it for?
Use it to require prefixes such as fix: or feat:, lowercase wording after the prefix, a space after the colon, and short message text.
Why use it?
It prevents inconsistent commit messages that make project history harder to scan, filter, and understand.

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 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 377 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

git-commit-standards 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.

Rule Details

  • Name: git_commit_standards

  • Description: Enforce structured Git commit messages.

Filters

  • file extension pattern: \\.git/.*

Enforcement Checks

  • Conditions:
    • pattern ^(?!fix|feat|perf|docs|style|refactor|test|chore): – Use a commit message prefix followed by colon and space (fix:, feat:, etc.).
      • More precise regex to ensure prefix is followed by colon and space
    • pattern ^(fix|feat|perf|docs|style|refactor|test|chore): [A-Z] – First word after prefix should be lowercase.
      • Check for uppercase after the prefix
    • pattern ^(fix|feat|perf|docs|style|refactor|test|chore): .{46,} – Keep commit message content (excluding prefix) under 46 characters.
      • More precise length check that excludes the prefix from the count
    • pattern ^(fix|feat|perf|docs|style|refactor|test|chore):(?! ) – Include a space after the colon in prefix.
      • Ensure there's a space after the colon

Suggestions

  • Guidance: Recommended commit format:
  • "fix: resolved bug in user authentication"
  • "feat: added new search functionality"
  • "docs: updated installation guide"
  • "style: fixed button alignment"
  • "refactor: simplified login logic"
  • "test: added unit tests for auth"
  • "chore: updated dependencies"
  • "perf: optimized database queries"

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.
