roco
Pixel-art mascot that reacts live to what Claude does. Pick one of 8, recolor it or create your own with /roco:crear. Mascota pixel art para Claude Code.
What it does
- Draws a pane, a band above the prompt
- Adds /roco
- Watches mcp__roco__guardar_personaje, mcp__roco__ajustar calls and can refuse them
- Hooks session.start, turn.complete, turn.start, ui.close
- Keeps its own state between turns
Good points
- No network calls
- Written in TypeScript
- Has a desktop-specific branch
- Handles errors
Code to start from
Two kinds: a starter modscode writes from the design above, and the lines of the mod's own code that draw it.
Starter (register.tsx)

// Each value below stands for one the mod works out at run time; put in your own.

This is a reading of the code text, not a security review: it does not run the mod, and it cannot see what a program the mod starts does. The check before installing is yours. How mods are chosen
Install it
Check it yourself before you install it. Mods run unsandboxed, with your permissions, and modscode does not vouch for what this code does. Read the code below (or run claude plugin validate . in its folder), weigh what it reaches, and install the commit you read.
Its repository is its marketplace. Add that marketplace (in the terminal with these commands, or in the desktop app's plugin settings) and install the mod from it:
/plugin marketplace add s4duq/roco/plugin install roco@rocoThis installs the marketplace's latest commit, which may not be the one read here (6d4465b6b0cc). Compare them before you install.
Ask Claude about it
With the modscode connector added, Claude can read this design, what its code reaches and its code, and build on them. Ask it like this:
Read the modscode design "s4duq-roco" with its code and make me a pane like itSearch them from Claude: the MCP connector
