# Sovereign Git Commit Analyzer > Git Commit Analyzer - Skill: `javimosch/sovereign-git-commit-analyzer` (Agent Skill) - Install (CLI): `npx skillmds@latest add javimosch/sovereign-git-commit-analyzer` - Raw SKILL.md: https://api.skillmd.com/api/skills/javimosch/sovereign-git-commit-analyzer/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: javimosch (https://skillmd.com/u/javimosch) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/javimosch/sovereign-git-commit-analyzer --- # Git Commit Analyzer A comprehensive git commit history analysis tool that generates detailed reports about your repository's development activity, contributor patterns, and commit message quality. ## Overview Git Commit Analyzer scans your repository's commit history and produces actionable insights including: - **Commit frequency** over configurable time windows - **Top contributors** ranked by commit count, lines changed, and files touched - **File change heatmap** showing which files are modified most often - **Commit message quality score** based on industry best practices - **Activity trends** showing development velocity over time This skill is designed for team leads, engineering managers, and developers who want to understand how their codebase evolves and identify areas for process improvement. ## Installation ### Via ClawHub ```bash openclaw install git-commit-analyzer ``` ### Manual Installation 1. Clone or download this skill into your OpenClaw skills directory: ```bash mkdir -p ~/.openclaw/skills/ cp -r git-commit-analyzer/ ~/.openclaw/skills/ ``` 2. Ensure the script is executable: ```bash chmod +x ~/.openclaw/skills/git-commit-analyzer/scripts/analyze.sh ``` 3. Verify the installation: ```bash openclaw list --installed ``` ## Requirements - **git** (version 2.0 or higher) - **bash** (version 4.0 or higher) - **awk** (GNU awk recommended) - **sort**, **uniq**, **wc** (standard Unix utilities) The script works on Linux, macOS, and Windows (via Git Bash, WSL, or MSYS2). ## Usage ### Basic Usage Run the analyzer in any git repository: ```bash openclaw run git-commit-analyzer ``` This produces a full report for the last 30 days on the current branch. ### Command-Line Options ```bash openclaw run git-commit-analyzer [OPTIONS] Options: --days Number of days to analyze (default: 30) --branch Branch to analyze (default: current branch) --author Filter commits by author email --output Output format: markdown, json, text (default: markdown) --top Number of top contributors to show (default: 10) --quality-threshold Minimum quality score to pass (default: 60) --heatmap Include file change heatmap (default: on) --no-heatmap Disable file change heatmap --since Start date in YYYY-MM-DD format --until End date in YYYY-MM-DD format --output-file Write report to a file instead of stdout ``` ### Direct Script Execution You can also run the analysis script directly: ```bash ./scripts/analyze.sh --days 90 --branch main --output markdown ``` ## Configuration ### skill.json Settings The `config` section in `skill.json` controls default behavior: ```json { "config": { "default_days": 30, "default_branch": "main", "output_format": "markdown", "quality_threshold": 60 } } ``` | Setting | Type | Default | Description | |----------------------|---------|------------|------------------------------------------| | `default_days` | integer | 30 | Default number of days to analyze | | `default_branch` | string | "main" | Default branch when none is specified | | `output_format` | string | "markdown" | Default output format | | `quality_threshold` | integer | 60 | Minimum passing quality score (0-100) | ### Environment Variables You can override settings via environment variables: ```bash export GCA_DAYS=90 export GCA_BRANCH=develop export GCA_OUTPUT=json export GCA_THRESHOLD=70 ``` ## Report Sections ### 1. Commit Frequency Shows the number of commits per day, week, or month within the analysis period. Includes a text-based bar chart for quick visual reference. Example output: ``` ## Commit Frequency (Last 30 Days) Total commits: 147 Average per day: 4.9 Most active day: 2026-02-10 (14 commits) Least active day: 2026-02-03 (0 commits) Week 1 | ############ (42) Week 2 | ######### (31) Week 3 | ############### (53) Week 4 | ###### (21) ``` ### 2. Top Contributors Ranks contributors by number of commits, with additional metrics for lines added, lines deleted, and number of files changed. Example output: ``` ## Top Contributors | Rank | Author | Commits | Lines Added | Lines Deleted | Files Changed | |------|-----------------|---------|-------------|---------------|---------------| | 1 | alice@corp.com | 45 | 3,210 | 1,105 | 89 | | 2 | bob@corp.com | 38 | 2,870 | 920 | 67 | | 3 | carol@corp.com | 29 | 1,540 | 680 | 45 | ``` ### 3. File Change Heatmap Identifies the most frequently modified files, which often correlate with complexity hotspots or areas needing refactoring. Example output: ``` ## File Change Heatmap | File | Changes | Last Modified | |-----------------------------|---------|---------------| | src/core/engine.py | 34 | 2026-02-20 | | src/api/routes.py | 28 | 2026-02-19 | | tests/test_engine.py | 22 | 2026-02-20 | | config/settings.yaml | 18 | 2026-02-15 | ``` ### 4. Commit Message Quality Scores commit messages based on these criteria: - **Length**: Subject line between 10 and 72 characters - **Imperative mood**: Starts with a verb (Add, Fix, Update, etc.) - **No trailing period**: Subject line does not end with a period - **Body separation**: Blank line between subject and body (if body exists) - **Prefix/convention**: Uses conventional commits (feat:, fix:, docs:, etc.) - **No vague words**: Avoids "misc", "stuff", "things", "update", "fix" alone Each criterion is worth points. The total quality score is a percentage. Example output: ``` ## Commit Message Quality Overall score: 74/100 (Good) | Criterion | Pass Rate | Score | |--------------------|-----------|-------| | Length | 89% | 18/20 | | Imperative mood | 72% | 14/20 | | No trailing period | 95% | 19/20 | | Body separation | 60% | 12/20 | | Conventional | 55% | 11/20 | Worst offenders: - "fix" (used 8 times with no further description) - "update stuff" (used 3 times) - "wip" (used 2 times) ``` ## Examples ### Analyze the last 90 days on the develop branch ```bash openclaw run git-commit-analyzer --days 90 --branch develop ``` ### Generate a JSON report for CI integration ```bash openclaw run git-commit-analyzer --output json --output-file report.json ``` ### Filter by a specific author ```bash openclaw run git-commit-analyzer --author "alice@company.com" --days 60 ``` ### Analyze a specific date range ```bash openclaw run git-commit-analyzer --since 2026-01-01 --until 2026-01-31 ``` ### Show only top 5 contributors without heatmap ```bash openclaw run git-commit-analyzer --top 5 --no-heatmap ``` ## Integration with CI/CD You can run the analyzer as part of your CI pipeline to track commit quality over time. Add this to your GitHub Actions workflow: ```yaml - name: Analyze Commits run: | openclaw run git-commit-analyzer \ --output json \ --output-file commit-report.json \ --quality-threshold 70 - name: Upload Report uses: actions/upload-artifact@v4 with: name: commit-analysis path: commit-report.json ``` If the quality score is below the threshold, the script exits with code 1, which will fail the CI step. ## Troubleshooting ### "Not a git repository" error Make sure you run the analyzer from within a git repository, or pass the repository path via the `--repo` flag. ### Empty report If the report shows zero commits, check that: - The branch name is correct (`--branch`) - The date range contains commits (`--days` or `--since`/`--until`) - The author filter matches existing contributors (`--author`) ### Slow performance on large repositories For repositories with 100k+ commits, use `--since` and `--until` to limit the analysis window instead of `--days`, which must walk the full log. ## License MIT License.
