# 🐾 Buddymon

A Claude Code **extension** that turns your coding sessions into a creature-collecting game.

Buddymon are discovered, caught, and leveled up through real development work — not separate from it.

> **How it works:** Buddymon uses Claude Code's hook and plugin system — it is not a UI mod. Notifications (encounters, XP, session summaries) appear as system-injected context in the chat thread, visible to both you and Claude. They do not appear in Thrumble's speech bubble or any other CC UI widget.

### Companion widgets and Buddymon

Claude Code supports personal companion widgets — small characters that sit beside the input box and comment in a speech bubble. These are user-configured, not built into CC by Anthropic. Buddymon is a separate community plugin and has no relationship to any specific companion.

The CC plugin API does not expose a hook to drive companion speech bubbles, so Buddymon cannot make your companion announce encounters. If Anthropic ships a companion speech API in a future release, Buddymon will adopt it.

Until then, Buddymon notifications arrive as chat context rather than companion barks. All game state (XP, encounters, roster) works regardless.

## What it does

- **Bug monsters** spawn from error output during your session (TypeErrors, CORS errors, race conditions, etc.)
- **Buddymon** are companions you assign to sessions — they gain XP and propose challenges
- **Challenges** are proactive goals your buddy sets at session start (write 5 tests, implement a feature in 30 min, net-negative lines)
- **Encounters** require you to fight or catch — catch rate improves if you write a failing test, isolate the repro, or add a comment

## Requirements

- [Claude Code](https://claude.ai/code) CLI
- Python 3 (already required by Claude Code)
- bash

---

## Install

Clone the repo anywhere and run the install script:

```bash
git clone https://git.opensourcesolarpunk.com/Circuit-Forge/buddymon.git
cd buddymon
bash install.sh
```

Then **restart Claude Code** and run:

```
/buddymon start
```

The install script:
- Creates a local `circuitforge` marketplace under `~/.claude/plugins/marketplaces/circuitforge/` (required — CC validates plugin names against the marketplace index)
- Symlinks the repo into `~/.claude/plugins/cache/circuitforge/buddymon/<version>/`
- Registers the plugin in `~/.claude/plugins/installed_plugins.json` and `~/.claude/plugins/known_marketplaces.json`
- Enables it in `~/.claude/settings.json`
- Creates `~/.claude/buddymon/` state directory with initial JSON files

Because it uses a symlink, any `git pull` in the repo is immediately live — no reinstall needed.

### Mirrors

You can clone from any of the three remotes:

```bash
# Forgejo (primary)
git clone https://git.opensourcesolarpunk.com/Circuit-Forge/buddymon.git

# GitHub
git clone https://github.com/CircuitForgeLLC/buddymon.git

# Codeberg
git clone https://codeberg.org/CircuitForge/buddymon.git
```

### Uninstall

```bash
bash install.sh --uninstall
```

Removes the symlink, deregisters from `installed_plugins.json`, and removes the `enabledPlugins` entry. Your `~/.claude/buddymon/` state (roster, XP, encounters) is left intact.

## State

All state lives in `~/.claude/buddymon/` — never in the repo.

```
~/.claude/buddymon/
├── roster.json        # owned Buddymon, XP, levels
├── encounters.json    # encounter history + active encounter
├── active.json        # current session assignment + challenge
└── session.json       # session stats (reset each session)
```
