commit-guidelines

A set of rules for writing commit messages and semantic version numbers, where message types indicate the size of a release change.

In plain words
What is it for?
Choosing commit types and formats for bug fixes, features, documentation, refactoring, tests, maintenance, and CI changes.
Why use it?
It reduces accidental major-version releases by clarifying which commit labels produce patch, minor, or major version bumps.

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.

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-guidelines 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.

Commit Guidelines - CRITICAL VERSION CONTROL

⚠️ CRITICAL WARNING - BREAKING CHANGES

NEVER use BREAKING CHANGE: in commit messages unless it's a REAL breaking change that requires users to modify their code!

The project uses semantic-release which automatically:

  • fix: → PATCH version (2.4.2 → 2.4.3)
  • feat: → MINOR version (2.4.2 → 2.5.0)
  • BREAKING CHANGE: → MAJOR version (2.4.2 → 3.0.0) ← AVOID THIS!

Commit Format

<type>: <emoji> <description>

[optional body]

[optional footer - NO BREAKING CHANGE unless absolutely necessary]

Allowed Types

For Version Bumps:

  • fix: 🐛 - Bug fixes (PATCH)
  • feat: ✨ - New features (MINOR)

For No Version Bump:

  • docs: 📝 - Documentation changes
  • style: 🎨 - Code formatting, styling
  • refactor: ♻️ - Code refactoring
  • test: ✅ - Adding tests
  • chore: 🔧 - Maintenance tasks
  • ci: 🚀 - CI/CD changes

Examples

✅ CORRECT:

# Minor feature (will be 2.4.2 → 2.5.0)
git commit -m "feat: ✨ add IDE selector integration"

# Bug fix (will be 2.4.2 → 2.4.3)
git commit -m "fix: 🐛 correct backup logic for single files"

# No version bump
git commit -m "docs: 📝 update README with new examples"

❌ WRONG:

# This creates MAJOR version bump (3.0.0)!
git commit -m "feat: ✨ add IDE selector

BREAKING CHANGE: Removed install command"

When IS a Breaking Change?

Only use BREAKING CHANGE: when:

  • API changes that break existing code
  • Removing public functions/methods
  • Changing function signatures
  • Removing CLI flags that users rely on
  • Changing default behavior that breaks existing workflows

Current Project Status

  • Current version: 3.0.1 (due to incorrect BREAKING CHANGE usage)
  • Going forward: Use only fix: and feat:
  • Avoid: BREAKING CHANGE: unless absolutely necessary

AI Assistant Guidelines

When making commits as "Agent AI":

  • Always use --author="Agent AI <[email protected]>"
  • Prefer fix: over feat: when in doubt
  • Never use BREAKING CHANGE: without explicit user confirmation
  • Keep commit messages concise and descriptive

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-guidelines is a cursor rule published in the GitHub repository tecnomanu/agent-rules-kit (35 stars, last pushed 11mo ago), licensed ISC. It adds 646 tokens to every session, about $0.0032 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 2026-08-30.
