Generate changelogs from git commits. Supports markdown, plain text, and JSON output with date ranges and tag-based filtering.
README (SKILL.md)
Git Changelog
When to use
Generate a human-readable changelog from git commit history. Works with any git repository.
Setup
No dependencies required. Uses only git and bash.
How to
Basic changelog (last 30 days or since last tag)
bash scripts/changelog.sh --repo /path/to/repo
Since a specific date
bash scripts/changelog.sh --repo /path/to/repo --since "2026-01-01"
Date range
bash scripts/changelog.sh --repo /path/to/repo --since "2026-01-01" --until "2026-02-01"
JSON output (for programmatic use)
bash scripts/changelog.sh --repo /path/to/repo --format json
Plain text output
bash scripts/changelog.sh --repo /path/to/repo --format plain
Output Formats
| Format | Description |
|---|---|
markdown |
Default. Headers, commit hashes, authors, dates |
plain |
Simple bullet list |
json |
Array of commit objects with hash, subject, author, date, type |
Options
| Flag | Description | Default |
|---|---|---|
--repo \x3Cpath> |
Repository path | Current directory |
--since \x3Cdate> |
Start date | Last tag or 30 days ago |
--until \x3Cdate> |
End date | Now |
--format \x3Cfmt> |
Output format | markdown |
--group |
Group by conventional commit type | Off (needs bash 4+) |
Notes
- Automatically detects the last git tag and uses it as the start point
- Excludes merge commits for cleaner output
- Conventional commit types (feat/fix/docs/etc) are extracted for JSON output
--groupmode requires bash 4+ (macOS ships with 3.2; install viabrew install bash)
Usage Guidance
The skill appears to do what it says: run the provided script against a local git repository to generate a changelog. Before using: (1) inspect or run the script in a sandbox — although harmless-looking, it will output all commit messages and metadata (these can contain secrets); (2) note the shebang points to /opt/homebrew/bin/bash but examples invoke it with 'bash', which avoids shebang issues; (3) ensure you run it only on repositories you trust or where exposing commit text is acceptable. Overall it's coherent and does not request extra permissions or network access.
Capability Analysis
Type: OpenClaw Skill
Name: git-changelog-gen
Version: 1.0.0
The skill bundle is benign. The `SKILL.md` instructions are straightforward and do not contain any prompt injection attempts. The `scripts/changelog.sh` script correctly validates the `--repo` argument by ensuring it's a valid git repository using `git rev-parse --git-dir` before performing any operations, which prevents arbitrary file system access. All git commands are constructed with properly quoted arguments, mitigating shell injection risks. The script only reads git history and outputs formatted text, with no evidence of data exfiltration, persistence, or malicious execution.
Capability Assessment
Purpose & Capability
Name/description match the included script and SKILL.md. The script operates on a local git repository and produces markdown/plain/text/JSON changelogs as advertised. No unrelated binaries, env vars, or config paths are requested. (Minor note: the script shebang points to /opt/homebrew/bin/bash, but examples call it with 'bash scripts/changelog.sh', so this is not an operational mismatch.)
Instruction Scope
Runtime instructions only invoke the included shell script against a repo path. The script only runs git commands, changes to the provided repository path, and formats commit metadata. It does not reference external endpoints, other system config, or environment variables. Users should be aware that commit messages/metadata may contain sensitive information and will be output.
Install Mechanism
No install spec; skill is instruction-only with one included script. Nothing is downloaded or written to disk by an installer. Dependencies are limited to git and bash, which matches the script's behavior.
Credentials
No environment variables, credentials, or config paths are required. The script does not read shell history or other unrelated files. There is no disproportionate access requested.
Persistence & Privilege
always is false and the skill does not request persistent presence or modify other skill/system configs. It can be invoked by the agent (normal default), but it does not autonomously elevate privileges or store tokens.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install git-changelog-gen - After installation, invoke the skill by name or use
/git-changelog-gen - Provide required inputs per the skill's parameter spec and get structured output
