## What it does

This command manages your `CHANGELOG.md` file. It invokes bash tools to read the last ten git commits, checks the latest version tag, and inspects `package.json` along with any existing changelog.

Entries follow the Keep a Changelog structure and Semantic Versioning. Changes fall into categories such as Added, Changed, Deprecated, Removed, Fixed, and Security. It also works with conventional commit prefixes like `feat` or `fix` to organize work.

Without a local git history, the command fails when running git commands.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command deployment/add-changelog
```

2. **Manually: put the files in place**
- File: `.claude/commands/add-changelog.md` — Call it with /add-changelog. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/add-changelog.md` — Call it with /prompts:add-changelog. Codex marks this format deprecated in favour of skills

- File: `.github/prompts/add-changelog.prompt.md`

### Gemini CLI

**Manually: put the files in place**
