commit

A guide for creating Git commit messages using Conventional Commits, a shared format for describing code changes. It also commits changes that have already been staged in Git.

In plain words
What is it for?
Use it when preparing a commit message or committing staged changes, including features, fixes, refactors, tests, documentation, and dependency work.
Why use it?
It makes commit history easier to scan and explains why a change was made. It also avoids accidentally staging files the developer has not selected.

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 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 2d 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

Commit

Generate a commit message and commit staged changes using git.

Based on the Conventional Commits v1.0.0 specification.

Guidelines

  • Only generate the message for staged files/changes
  • Don't add any files using git add - user decides what to add
  • DO NOT add any ads or footers

Format

<type>(<scope>): <message title>

<bullet points summarizing what was updated>

Rules

  • Title: lowercase, no period, max 50 characters
  • Scope: optional, feature affected
  • Body: explain why, not just what
  • Bullet points: concise and high-level

Allowed Types

Type Description
feat New feature
fix Bug fix
chore Maintenance (tooling, deps)
docs Documentation changes
refactor Code restructure (no behavior change)
test Adding or refactoring tests
style Code formatting (no logic change)
perf Performance improvements

Examples

feat(auth): add JWT login flow

- Implemented JWT token validation logic
- Added documentation for the validation component
fix(ui): handle null pointer in sidebar
refactor(api): split user controller logic

- Extracted validation into separate module
- Simplified error handling flow
  • Reference issues: Closes #123
  • Breaking changes: Start with BREAKING CHANGE:

Avoid

  • Vague titles: "update", "fix stuff"
  • Overly long or unfocused titles
  • Excessive detail in bullet points
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.

commit is a skill published in the GitHub repository Casper-Studios/casper-marketplace (12 stars, last pushed 15d ago), licensed MPL-2.0. It adds 24 tokens to every session and 445 once invoked, about $0.0001 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.
