About claudemon

claudemon is a terminal-based Pokémon game that runs alongside Claude Code. It turns idle waiting time into quick battles: each prompt becomes a step through tall grass, and every 20 seconds of agent work advances the game. Encounters appear in the status line, and you fight them in a second terminal tab. The plugin is fully local, requires no account, and ships with all 151 original Pokémon under the MIT license.

Review

Claude Code users know the rhythm: type a prompt, then stare at the terminal while the agent works. claudemon fills those gaps with a lightweight game that only progresses when Claude does. It doesn't change how fast Claude works, and it won't interrupt your flow - it just sits in the status line and waits for you to check in.

Key Features

• Gameplay tied directly to Claude Code activity. Your prompts count as steps, and every 20 seconds of agent runtime triggers another step, so the game only moves when you're waiting.
• Wild Pokémon encounters announced in the status line. When something jumps out, you switch to a second terminal tab to battle and catch it.
• All 151 original Pokémon are available locally. No server calls, no account creation, no data leaves your machine.
• Installed as a Claude Code plugin via the GitHub-based marketplace. The command /plugin marketplace add zamarrowski/claudemon pulls the game straight from the repository.
• Open source under the MIT license. Anyone can inspect, modify, or fork the code on GitHub.

Pricing and Value

claudemon is free. There are no paid tiers, subscriptions, or in-app purchases. The entire project is open source and distributed under the MIT license, so you can use it indefinitely at no cost. The value is entirely in making wait time less tedious - it doesn't speed up Claude Code or add productivity features.

Pros

• Converts idle seconds into a game without slowing down the main task.
• Runs completely offline; no personal data or API keys required.
• Installation is a single command inside Claude Code, with no external registries or accounts.
• The MIT license means you're free to adapt it or contribute back.
• Gives completionists a reason to enjoy longer agent runs - filling the Pokédex becomes a side quest.

Cons

• Requires Claude Code. Developers using other AI coding tools like GitHub Copilot or Codex won't be able to run it.
• Encounters are currently based on elapsed time, not on whether the agent produced working code. A run that spins for 20 minutes and fails still rewards a catch. (A future update may tie catches to test results, but that's not shipped yet.)
• The second terminal tab approach is unusual. Some users may find managing two tabs distracting, especially on smaller screens.

claudemon fits neatly into the workflow of someone who spends hours in Claude Code and wants a low-friction distraction during short waits. It's not a tool for people who need to scrutinize every line of output or who don't use Claude Code at all. For those who already have a terminal open and a few seconds to spare, it turns the waiting itself into a small, optional game.
