generate-commit-msg

A command that reads staged Git changes, meaning edits already selected for the next commit, and writes a Conventional Commit message. That format labels changes with types such as feature, fix, documentation, or refactoring.

In plain words
What is it for?
Use it after staging files to generate a short commit message, or request a fuller message with a summary and change list, with optional type and scope overrides.
Why use it?
It saves time writing commit text and makes the purpose of changes clearer in project history. It also keeps the title within the stated length and formatting rules.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 285 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

generate-commit-msg 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

Generate Commit Message

Generate conventional commit message from staged changes.

Arguments

$ARGUMENTS: [--full] [--scope <scope>] [--type <type>]

Argument Default Description
--full off Include markdown body with summary and changes
--scope auto Override scope (e.g., api, ui, docs)
--type auto Override type (e.g., feat, fix, refactor)

Workflow

  1. Run git diff --staged — if empty, tell user to stage files first
  2. Analyze changes and generate message in format: <type>(<scope>): <summary>

Output Format

Quick Mode (default):

<type>(<scope>): <summary>

Full Mode (--full):

<type>(<scope>): <summary>

<Brief summary of what changed and why>

- <change 1>
- <change 2>

Constraints

  • Max 72 characters for title
  • No emojis, no markdown in title

CRITICAL: Output ONLY the raw commit message. No explanations, no analysis, no "Here's the message:", no code blocks. Just the message text itself.

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.
