2048 above the Claude Code prompt: slide and merge tiles up to 2048. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

Organization control mod: withholds the http and process nouns from $ so no plugin beneath it can reach the network or spawn processes, refuses user-tier plugins by name allowlist or by the $ calls their source declares, and withholds the Bash tool (shellPolicy "deny", default) or, in "guardrail" mode, denies well-known network clients as a bypassable speed bump. Hooks engine.create, plugin.register and tool.call; seat it in the managed prepend tier.

/aitmpl opens a component browser above the prompt: the aitmpl.com catalog (agents, commands, MCPs, settings, hooks, skills, loops, mods) read live from the site's public JSON through $.http.fetch. Pick a type or a trending component, filter, page, open a component and install it from there ($.process.run with the fixed CLI argv and a validated path, no shell), drop its install command into the prompt, or open its page in your browser. Hooks session.start, command.run and ui.render on AbovePrompt; browsing costs no tokens.

Denies Bash commands that match destructive patterns (recursive rm on roots, force push, hard reset, destructive SQL, disk formatting) before they run. A tool.call hook with a Bash matcher that returns { deny } without calling next.

Games above the Claude Code prompt (snake, Tetris, 2048, Minesweeper, Flappy, Pong, typing test, Space Invaders, Doom) plus a pet that grows as Claude tests, commits and edits. Clones of the genre, not affiliated with or endorsed by Tetris Holding, Taito, Atari or id Software. Needs function hooks (early access) and an interactive terminal.

Space Invaders above the Claude Code prompt where every wave is the code Claude just wrote: each line an Edit or Write added becomes a row of the formation and every two characters one alien, so you shoot your own diff. Ship, one shot at a time, bombs, three lives, best score. Zero tokens. Needs function hooks (early access) and an interactive terminal.

Doom above the Claude Code prompt: a corridor shooter: imps, a shotgun, and the floor below. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

Space Invaders above the Claude Code prompt: shoot each wave before it lands. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

Screens every prompt going into the conversation and every reply coming out of it with TypeSafe's Jev, a System One decision model, the way TypeSafe's guardrails cookbook does: one request per message asks a battery of hazard questions (jailbreak, harm or a crime, a diagnosis or a dosage, self-harm) and scores how much harm complying would do. The thresholds live here, in a named policy (strict or permissive), and turn the probabilities into pass, review (the user is asked), block (the prompt is dropped, or the reply withheld) or support. Falls back to the engine's built-in classifier when no key is set.

Picks the model and the reasoning effort for each task with TypeSafe's Jev, a System One decision model reached either through TypeSafe's own API or the Vercel AI Gateway. Routes subagent models at agent.spawn and the main loop's effort and model at turn.step, in both directions, falling back to the engine's built-in classifier when no key is set.

Keeps the skill listing out of the context window and lets TypeSafe's Jev, a System One decision model, pick at most one skill per prompt from the skills' descriptions, the way TypeSafe's skill-suggestion cookbook does: one request ranks every skill and asks whether the prompt needs a skill at all, a second re-reads the top three with their SKILL.md and can reject them all. The winner's SKILL.md is attached to the prompt, so the skills can be hidden from the model altogether (/jev-skill-suggestion:setup makes them user-invocable-only and /context counts them at 0). Falls back to the engine's built-in classifier when no key is set.

Asks the user, in the engine's AskUserQuestion dialog ($.ui.ask), before Claude edits or overwrites a file larger than a configurable line count; denies by default when nobody can answer (headless runs). A tool.call hook on Edit and Write using $.fs.read.

by Seza Akgün

Minesweeper above the Claude Code prompt: open every cell that is not a mine. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

Rewrites npm and npx invocations to pnpm (or yarn / bun) before the Bash tool runs them and tells the model what ran through context. A tool.call hook that forwards a modified event (the modifying placement).

by claude-code-templates

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.

by Seza Akgün

A virtual pet above the Claude Code prompt that grows as Claude works: passing tests, commits and edits grant XP and mood, failing tests cost mood, idling drains it; egg → baby → kid → adult → legend. Zero tokens. Split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal.

pi agent for claude: a `pi` subagent type whose model steps run the pi CLI, so pi subagents and agent-team teammates live in Claude Code's own agent UI, streamed live, on any model pi can reach.

by Seza Akgün

Pong above the Claude Code prompt: first to 5 against the computer. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

Denies Edit, Write and NotebookEdit calls on sensitive paths (.env files, lockfiles, CI workflows, git internals, private keys) with a glob allowlist override. A tool.call hook with an array matcher.

by claude-code-templates

Redacts API keys, tokens, JWTs, private keys and connection strings from every tool result before the model reads them, notes the redaction through context, and refuses to echo a redacted placeholder back into a Bash command. A tool.call hook in the after placement.

Snake above the Claude Code prompt: eat, grow, and keep off the walls and yourself. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs function hooks (early access) and an interactive terminal with a mouse.

A tower defense above the Claude Code prompt where every enemy is one of Claude's real tool calls: Bash sends runners, an Edit or Write a slow tank, a web or MCP call a flyer, an Agent a boss. Build and upgrade towers by clicking beside the road, hold the base through Claude's turn. Zero tokens. Needs function hooks (early access) and an interactive terminal with a mouse.
