## What it does

Entering Plan Mode launches Dino Runner, Snake, or Flappy Bird. A live panel displays Claude’s tool calls; the game pauses when Claude asks you for input, then shows a completion screen with confetti. Scores are stored locally and can be shared through a signed verification URL.

The hook uses shell scripts for startup, activity tracking, plan detection, and input prompts, alongside `server.js` and `index.html`. Node.js and `curl` are required. It opens the browser with `open`, so it runs on macOS; install it globally to use it across projects.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --hook automation/plan-mode-game
```

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/automation/plan-mode-game.json

## When to use it
- launch a game when Claude Code enters Plan Mode
- watch tool calls as Claude builds a plan
- pause the game while Claude waits for a response
- save a score locally and share its verification link

## Example prompts
- Plan the changes for this project in Plan Mode.
- Inspect the project and draft a work plan.
- Ask me a question if you need more information to plan the changes.
