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
Clone or download this skill into your OpenClaw skills directory:

bash
mkdir -p ~/.openclaw/skills/
cp -r git-commit-analyzer/ ~/.openclaw/skills/


Ensure the script is executable:

bash
chmod +x ~/.openclaw/skills/git-commit-analyzer/scripts/analyze.sh


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    | [email protected]  | 45      | 3,210       | 1,105         | 89            |
| 2    | [email protected]    | 38      | 2,870       | 920           | 67            |
| 3    | [email protected]  | 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 "[email protected]" --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.
