my-coder

Minimal AI coding agent — stripped from Claude Code, rebuilt from scratch. ~1,800 lines, 12 tools, multi-agent, zero bloat.

Install

npm i -g my-coder

Requires Node.js ≥ 18.

Configure

Set your API key via environment variable:

export MYCODER_API_KEY=sk-ant-...   # Anthropic (Claude)
# or
export MYCODER_API_KEY=sk-...       # DeepSeek / OpenAI

Optional: set model and provider in ~/.mycoder.json (auto-created on first run):

{
  "model": "deepseek-chat",
  "provider": "openai",
  "openaiBase": "https://api.deepseek.com"
}

User memory: write personal preferences to ~/.mycoder/MYCODER.md — automatically injected into every session.
