Content

Early access. A mod is a complete Claude Code plugin built on function hooks (Anthropic's mods/ layout); it loads in Claude Code 2.1.259+ with CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 and the $ API may still change between releases. Hooks module: hooks/register.tsx. Run claude plugin validate on the installed folder to see every event it hooks and every $ call it makes.

tetris

Tetris above the Claude Code prompt, for the minutes Claude spends working: fit the falling pieces and clear lines. The game pauses and its status line says so when Claude finishes the turn, so you never miss a reply. Playing costs no tokens: the mod answers every key and click itself.

A single game split out of sezaakgun/cc-arcade (MIT, by Seza Akgün). Want all nine games, a picker and the pet in one plugin? Install games/cc-arcade instead.

Play

/tetris opens the board above the prompt (/tetris stop or the close button closes it).
Click the board to give it the keyboard; Esc gives the keyboard back to the prompt.
← → move, ↑ or x rotates, ↓ drops one row, Space drops to the bottom, p pauses, r restarts. The pieces fall faster every ten lines.

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

CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 claude

It is written to .claude/skills/tetris/, which Claude Code auto-loads as tetris@skills-dir. For one session with hot reload: CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 claude --plugin-dir .claude/skills/tetris.

Requirements
