git-commit

A commit-writing guide for Git, the version-control system used to record code changes. It formats commits using conventional types such as feature, fix, test, or documentation.

In plain words
What is it for?
It helps inspect a code diff, choose a suitable commit type and scope, write a short imperative subject, and explain why the change was made.
Why use it?
It removes the guesswork from writing consistent commit messages and makes a project's change history easier to understand.

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 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.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git Commit

Create semantic git commits that match the existing history in this repo. Analyze the actual diff to pick the right type, an optional scope, and a subject that reads well next to git log --oneline. Body explains the why — the diff already shows the what.

Commit format

<type>(<optional-scope>): <imperative subject>

[optional body — WHY, not WHAT]

[optional footer(s)]
  • Subject: imperative mood, English, ≤ 70 characters. No trailing period.
  • Scope: the single module or package most affected. Omit when the change is cross-cutting.
  • Body: explain motivation (constraint, incident, decision). The diff already shows what.
  • Footers: Closes #123, BREAKING CHANGE: …, etc.

Commit types

Type When
feat New user-visible capability
fix Bug fix (behavior was wrong, now correct)
refactor Internal change, same behavior
test Add or adjust tests
db Schema / migration change
ci Pipeline, actions, coverage, release plumbing
chore Housekeeping (deps, config, tooling) that isn't ci or db
docs Docs-only change
style Formatting only (no logic)
perf Change motivated by a measurable performance win

Scopes

Only use a scope when the change clearly centers on one area. Common shapes:

  • Domain module: name of the module the diff sits in (auth, users, <feature>).
  • Monorepo package: name of the package (ui, eslint-config, typescript-config, skills).
  • Cross-cutting infrastructure (docker, CI, tooling at the repo root): usually no scope.

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.
