code-commit

A guide for creating Conventional Commits, a standard format for Git commit messages that labels changes such as features, fixes, documentation, or tests. It also checks that the selected changes form one coherent story.

In plain words
What is it for?
Use it when writing or reviewing commit messages, preparing a git commit, or deciding whether a change is a feature, fix, documentation update, refactor, test, or other standard type.
Why use it?
Consistent commit messages make project history easier to read and automate. The guidance helps explain what changed and why without vague or misleading titles.

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

code-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 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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Conventional Commit Skill

Create coherent, reviewable commits that follow the Conventional Commits specification. Message syntax matters, but the selected changes must tell one clear story too.

Message Format

Every generated commit has a title and body:

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

<1-5 lines describing the change and, when useful, its reason or effect>

Use a lowercase scope that identifies the affected component. The title is concise, imperative, lowercase, and has no trailing period. The body is concrete: explain the behavior, motivation, or important implementation decision rather than restating the title.

Type Use for
feat New user-facing capability
fix Corrected behavior
docs Documentation only
style Formatting only
refactor Restructuring without behavior change
test Tests only
chore Maintenance or tooling
perf Performance improvement
ci Continuous integration configuration
build Build system or dependencies
revert Reverting a prior commit

Breaking changes may use ! after the type or scope, a BREAKING CHANGE: footer, or both. Include issue footers such as Closes #123 only when the issue is known.

Create a Commit

When the user asks to commit, first inspect the complete worktree:

  1. Run git status --short.
  2. Read both git diff --cached and git diff so pre-staged work is not mistaken for the entire change.
  3. List untracked files with git ls-files --others --exclude-standard and inspect relevant ones.
  4. Read recent subjects with git log --oneline -10 to match established scopes and wording.
  5. Flag likely secrets, credentials, local configuration, or generated output. Do not stage them without explicit direction.

Decide Whether to Split

Default to one commit containing all intended, related changes. Look for an obvious file-level split only when changes are independent and each group can stand alone.

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.

code-commit is a skill published in the GitHub repository martinffx/atelier (44 stars, last pushed 22d ago), licensed MIT. It adds 62 tokens to every session and 1,278 once invoked, about $0.0003 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.
