Ensure the script is executable:\r\n\r\n```bash\r\nchmod +x ~/.openclaw/skills/git-commit-analyzer/scripts/analyze.sh\r\n```\r\n\r\n3. Verify the installation:\r\n\r\n```bash\r\nopenclaw list --installed\r\n```\r\n\r\n## Requirements\r\n\r\n- **git** (version 2.0 or higher)\r\n- **bash** (version 4.0 or higher)\r\n- **awk** (GNU awk recommended)\r\n- **sort**, **uniq**, **wc** (standard Unix utilities)\r\n\r\nThe script works on Linux, macOS, and Windows (via Git Bash, WSL, or MSYS2).\r\n\r\n## Usage\r\n\r\n### Basic Usage\r\n\r\nRun the analyzer in any git repository:\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer\r\n```\r\n\r\nThis produces a full report for the last 30 days on the current branch.\r\n\r\n### Command-Line Options\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer [OPTIONS]\r\n\r\nOptions:\r\n  --days <number>       Number of days to analyze (default: 30)\r\n  --branch <name>       Branch to analyze (default: current branch)\r\n  --author <email>      Filter commits by author email\r\n  --output <format>     Output format: markdown, json, text (default: markdown)\r\n  --top <number>        Number of top contributors to show (default: 10)\r\n  --quality-threshold   Minimum quality score to pass (default: 60)\r\n  --heatmap             Include file change heatmap (default: on)\r\n  --no-heatmap          Disable file change heatmap\r\n  --since <date>        Start date in YYYY-MM-DD format\r\n  --until <date>        End date in YYYY-MM-DD format\r\n  --output-file <path>  Write report to a file instead of stdout\r\n```\r\n\r\n### Direct Script Execution\r\n\r\nYou can also run the analysis script directly:\r\n\r\n```bash\r\n./scripts/analyze.sh --days 90 --branch main --output markdown\r\n```\r\n\r\n## Configuration\r\n\r\n### skill.json Settings\r\n\r\nThe `config` section in `skill.json` controls default behavior:\r\n\r\n```json\r\n{\r\n  \"config\": {\r\n    \"default_days\": 30,\r\n    \"default_branch\": \"main\",\r\n    \"output_format\": \"markdown\",\r\n    \"quality_threshold\": 60\r\n  }\r\n}\r\n```\r\n\r\n| Setting              | Type    | Default    | Description                              |\r\n|----------------------|---------|------------|------------------------------------------|\r\n| `default_days`       | integer | 30         | Default number of days to analyze        |\r\n| `default_branch`     | string  | \"main\"     | Default branch when none is specified    |\r\n| `output_format`      | string  | \"markdown\" | Default output format                   |\r\n| `quality_threshold`  | integer | 60         | Minimum passing quality score (0-100)    |\r\n\r\n### Environment Variables\r\n\r\nYou can override settings via environment variables:\r\n\r\n```bash\r\nexport GCA_DAYS=90\r\nexport GCA_BRANCH=develop\r\nexport GCA_OUTPUT=json\r\nexport GCA_THRESHOLD=70\r\n```\r\n\r\n## Report Sections\r\n\r\n### 1. Commit Frequency\r\n\r\nShows the number of commits per day, week, or month within the analysis period.\r\nIncludes a text-based bar chart for quick visual reference.\r\n\r\nExample output:\r\n\r\n```\r\n## Commit Frequency (Last 30 Days)\r\n\r\nTotal commits: 147\r\nAverage per day: 4.9\r\nMost active day: 2026-02-10 (14 commits)\r\nLeast active day: 2026-02-03 (0 commits)\r\n\r\nWeek 1  | ############ (42)\r\nWeek 2  | ######### (31)\r\nWeek 3  | ############### (53)\r\nWeek 4  | ###### (21)\r\n```\r\n\r\n### 2. Top Contributors\r\n\r\nRanks contributors by number of commits, with additional metrics for lines\r\nadded, lines deleted, and number of files changed.\r\n\r\nExample output:\r\n\r\n```\r\n## Top Contributors\r\n\r\n| Rank | Author          | Commits | Lines Added | Lines Deleted | Files Changed |\r\n|------|-----------------|---------|-------------|---------------|---------------|\r\n| 1    | alice@corp.com  | 45      | 3,210       | 1,105         | 89            |\r\n| 2    | bob@corp.com    | 38      | 2,870       | 920           | 67            |\r\n| 3    | carol@corp.com  | 29      | 1,540       | 680           | 45            |\r\n```\r\n\r\n### 3. File Change Heatmap\r\n\r\nIdentifies the most frequently modified files, which often correlate with\r\ncomplexity hotspots or areas needing refactoring.\r\n\r\nExample output:\r\n\r\n```\r\n## File Change Heatmap\r\n\r\n| File                        | Changes | Last Modified |\r\n|-----------------------------|---------|---------------|\r\n| src/core/engine.py          | 34      | 2026-02-20    |\r\n| src/api/routes.py           | 28      | 2026-02-19    |\r\n| tests/test_engine.py        | 22      | 2026-02-20    |\r\n| config/settings.yaml        | 18      | 2026-02-15    |\r\n```\r\n\r\n### 4. Commit Message Quality\r\n\r\nScores commit messages based on these criteria:\r\n\r\n- **Length**: Subject line between 10 and 72 characters\r\n- **Imperative mood**: Starts with a verb (Add, Fix, Update, etc.)\r\n- **No trailing period**: Subject line does not end with a period\r\n- **Body separation**: Blank line between subject and body (if body exists)\r\n- **Prefix/convention**: Uses conventional commits (feat:, fix:, docs:, etc.)\r\n- **No vague words**: Avoids \"misc\", \"stuff\", \"things\", \"update\", \"fix\" alone\r\n\r\nEach criterion is worth points. The total quality score is a percentage.\r\n\r\nExample output:\r\n\r\n```\r\n## Commit Message Quality\r\n\r\nOverall score: 74/100 (Good)\r\n\r\n| Criterion          | Pass Rate | Score |\r\n|--------------------|-----------|-------|\r\n| Length             | 89%       | 18/20 |\r\n| Imperative mood    | 72%       | 14/20 |\r\n| No trailing period | 95%       | 19/20 |\r\n| Body separation    | 60%       | 12/20 |\r\n| Conventional       | 55%       | 11/20 |\r\n\r\nWorst offenders:\r\n  - \"fix\" (used 8 times with no further description)\r\n  - \"update stuff\" (used 3 times)\r\n  - \"wip\" (used 2 times)\r\n```\r\n\r\n## Examples\r\n\r\n### Analyze the last 90 days on the develop branch\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer --days 90 --branch develop\r\n```\r\n\r\n### Generate a JSON report for CI integration\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer --output json --output-file report.json\r\n```\r\n\r\n### Filter by a specific author\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer --author \"alice@company.com\" --days 60\r\n```\r\n\r\n### Analyze a specific date range\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer --since 2026-01-01 --until 2026-01-31\r\n```\r\n\r\n### Show only top 5 contributors without heatmap\r\n\r\n```bash\r\nopenclaw run git-commit-analyzer --top 5 --no-heatmap\r\n```\r\n\r\n## Integration with CI/CD\r\n\r\nYou can run the analyzer as part of your CI pipeline to track commit quality\r\nover time. Add this to your GitHub Actions workflow:\r\n\r\n```yaml\r\n- name: Analyze Commits\r\n  run: |\r\n    openclaw run git-commit-analyzer \\\r\n      --output json \\\r\n      --output-file commit-report.json \\\r\n      --quality-threshold 70\r\n\r\n- name: Upload Report\r\n  uses: actions/upload-artifact@v4\r\n  with:\r\n    name: commit-analysis\r\n    path: commit-report.json\r\n```\r\n\r\nIf the quality score is below the threshold, the script exits with code 1,\r\nwhich will fail the CI step.\r\n\r\n## Troubleshooting\r\n\r\n### \"Not a git repository\" error\r\n\r\nMake sure you run the analyzer from within a git repository, or pass the\r\nrepository path via the `--repo` flag.\r\n\r\n### Empty report\r\n\r\nIf the report shows zero commits, check that:\r\n- The branch name is correct (`--branch`)\r\n- The date range contains commits (`--days` or `--since`/`--until`)\r\n- The author filter matches existing contributors (`--author`)\r\n\r\n### Slow performance on large repositories\r\n\r\nFor repositories with 100k+ commits, use `--since` and `--until` to limit the\r\nanalysis window instead of `--days`, which must walk the full log.\r\n\r\n## License\r\n\r\nMIT License.
