commit-message

A tool that prepares a concise Git commit message from the current changes and status. It writes the proposed message to a file for the developer to review.

In plain words
What is it for?
Use it to create English commit messages for Drupal projects, including the required drupal.org issue format when applicable.
Why use it?
It saves time when summarising a set of changes while leaving the final commit and push under the developer’s control. The messages follow the specified Conventional Commits format.

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-message 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 — 272 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Generate a commit message file from the current git state. The user reviews it and commits manually. This skill does NOT run git commit or git push.

Output File

The message is saved to commit-msg.txt in the project root. The user can then:

# Option A: use the file directly
git commit -F commit-msg.txt

# Option B: copy the subject line only
git commit -m "$(head -1 commit-msg.txt)"

# After committing, clean up
rm commit-msg.txt

Language Rules

  1. Commit messages are ALWAYS in English — Drupal community standard, same contract as the translations rule: the conversation language never leaks into the repository. A user talking in Spanish still gets an English commit message. The single exception: the user EXPLICITLY requests another language for this message.
  2. Technical terms (file names, function names, config keys) stay in their original form
  3. Never mention AI, assistants, or automated tools in the message — write as if the developer authored it

Step 1: Gather Context

Run these commands to understand the full picture:

# Overview: what files changed, how much
git diff --stat
git diff --cached --stat

# New, deleted, renamed files (not visible in diff)
git status --short

# Full diff for semantic analysis
git diff
git diff --cached

# Recent commit style for consistency
git log --oneline -10

Important distinctions:

  • git diff = unstaged changes (not yet added)
  • git diff --cached = staged changes (already git add-ed)
  • If everything is unstaged, analyze git diff. If staged, analyze git diff --cached. If mixed, analyze both.

Step 2: Analyze Changes

From the diff output, determine:

2a. Change Type (Conventional Commits)

Type When to use
feat New functionality, new files that add capabilities
fix Bug fix, error correction, broken behavior repaired
refactor Code restructuring without changing behavior
docs Documentation, README, comments only
style Formatting, whitespace, linting fixes (no logic change)
test Adding or modifying tests
chore Build config, dependencies, CI, tooling
perf Performance improvement
ci CI/CD pipeline changes
build Build system, external dependencies

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-message is a skill published in the GitHub repository trebormc/drupal-ai-agents (10 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 161 tokens to every session and 2,341 once invoked, about $0.0008 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 2026-08-31.
