collect-commit-info
Analyze staged files, group by category, and generate conventional commit specs as JSON.
When & Why to Use This Skill
The collect-commit-info skill automates the generation of structured Git commit messages by analyzing staged files and their diffs. It intelligently categorizes changes into groups such as features, fixes, documentation, and dependencies, ensuring strict adherence to Conventional Commit specifications while significantly streamlining the version control workflow for developers.
Use Cases
- Automated Commit Drafting: Quickly generate precise, conventional commit messages for staged changes by automatically analyzing code diffs to determine the correct type (feat, fix, refactor).
- Logical Change Grouping: Automatically split and group diverse staged files into separate, logical commit units (e.g., separating dependency updates from source code changes) for a cleaner git history.
- Standardizing Repository History: Enforce consistent commit message formats across a team or project, improving long-term maintainability and making changelog generation easier.
- Multi-Language Support: Generate commit messages in the preferred language of the project or the developer's current conversation context.

This skill analyzes staged git files and returns commit specifications as JSON. It:
- Collects staged file metadata via script
- Reads diff content to understand changes
- Groups files by category (deps, ci, config, source, test, docs)
- Generates conventional commit messages for each group
- Returns JSON specs for the caller to execute
Arguments
| Arg | Default | Description |
|---|---|---|
--lang |
context | Message language (conversation context → system locale → en) |
Output Contract
This skill ALWAYS returns JSON. The caller executes git commands based on this output.
Success:
{
"commits": [
{"message": "type(scope): subject\n\nBody", "files": ["file1", "file2"]}
],
"summary": {"total_commits": 1, "total_files": 2}
}
Error:
{"error": "description", "error_code": "CODE"}
Workflow
Step 1: Collect file info
${CLAUDE_PLUGIN_ROOT}/skills/collect-commit-info/scripts/collect-info.sh --lang <code>
Script returns JSON with temp_dir, files array (with categories), and paths.diff_content.
On error JSON → return it immediately and stop.
Step 2: Read diff content
Read the file at paths.diff_content to understand what changed.
Step 3: Group files by category
Group files from the files array. Commit order:
deps- Dependencies (package.json, lock files)ci- CI/CD (.github/*)config- Configuration (*.yml, *.toml, rc files)source- Source codetest- Tests (_test., .test., .spec.)docs- Documentation (.md, docs/)
Step 4: Generate commit messages
For each group, create a conventional commit message:
type(scope): imperative subject (max 50 chars)
Optional body explaining what and why.
Type by category:
| Category | Type |
|---|---|
| deps | chore |
| ci | ci |
| config | chore |
| source | feat/fix/refactor (analyze diff) |
| test | test |
| docs | docs |
For source files, analyze diff to determine type:
- New functionality →
feat - Bug fixes, error handling →
fix - Restructuring, cleanup →
refactor
Scope: Derive from paths (e.g., src/auth/* → auth)
Language: Use lang.effective from script output. If conversation context indicates a preferred language, use that instead.
Step 5: Cleanup and return
${CLAUDE_PLUGIN_ROOT}/skills/collect-commit-info/scripts/cleanup.sh <temp_dir>
Return the JSON commit specs.
