pacman

Pac-Man above the Claude Code prompt: a 19×15 maze, four ghosts that chase, scatter and flee, power pellets, three lives and faster levels. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. Needs function hooks (early access) and an interactive terminal. Zero tokens: the mod answers every key and click itself and never asks the model anything.

Play

1. /pacman opens the maze above the prompt (/pacman stop or the close button closes it).
2. Click the maze to give it the keyboard; Esc gives the keyboard back to the prompt.
3. Arrows or WASD steer: the turn is taken at the next opening. Space or p pauses, r restarts.
4. Pellets are 10 points, a power pellet 50 and makes the ghosts edible for a few seconds: 200, 400, 800, 1600 in a row. The row in the middle is a tunnel. Clear the maze and the next level is faster.

The four ghosts behave like the originals: red chases you, pink aims four cells ahead of you, cyan mirrors red through you, green chases while far and runs to its corner while near. They switch to a scatter pattern now and then.

Your best score is kept in the plugin's store across sessions.

Install

npx claude-code-templates@latest --mod games/pacman
CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 claude

It is written to .claude/skills/pacman/, which Claude Code auto-loads as pacman@skills-dir. For one session with hot reload: CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 claude --plugin-dir .claude/skills/pacman. claude plugin validate .claude/skills/pacman prints every event it hooks and every $ call it makes.

How it is built

hooks/register.tsx is the hooks module: it registers /pacman, mounts the board on the AbovePrompt band and keeps the score in $.store. hooks/games/*.ts is the game's logic, pure functions with no drawing, and hooks/boards/*.tsx is the surface module that draws it in two-character cells on the drawing thread and takes the keys and the mouse. Written for aitmpl.com against Anthropic's published function-hooks declarations.

Requirements

• Claude Code 2.1.269 or later (the first build whose function hooks draw above the prompt) with CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1. The $ API is early access and may change between releases.
• An interactive terminal that reports the mouse. Nothing draws in claude -p, the desktop app or mobile.
• A terminal font with box-drawing and block characters.
