## What it does

change-tracker listens to `PostToolUse` events in Claude Code. After `Edit` or `MultiEdit`, it appends the modified file path to a log. After `Write`, it records the created file instead. Each entry includes the date, time, and action type.

The hook writes to `~/.claude/changes.log`, so all activity goes into one fixed file. The log grows when the matching tools run. If `~/.claude/changes.log` cannot be written, new entries will not be added.

Install it with `npx claude-code-templates@latest --hook development-tools/change-tracker`, then use `.claude/settings.json` for the configuration. The setup is intended for Claude Code.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --hook development-tools/change-tracker
```

2. **Manually: put the files in place**
- File: `.claude/settings.json` — The hooks block: event (PreToolUse, PostToolUse, Stop…) → command. Personal ones go to ~/.claude/settings.json

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/hooks/development-tools/change-tracker.json

## When to use it
- track files changed by Claude Code
- record when a file was edited
- separate created files from modified ones
- keep a plain activity log for agent actions

## Example prompts
- Edit `src/app.js` and record the change in the activity log.
- Create `config/local.json`, then check that the event was logged.
- Update several files with `MultiEdit` and show the change log.
