Automatically extracts reusable patterns like error resolutions and workarounds from Claude Code sessions via Stop hook and saves as learned skills.
From atum-systemnpx claudepluginhub arnwaldn/atum-system --plugin atum-systemThis skill uses the workspace's default tool permissions.
config.jsonevaluate-session.shProvides UI/UX resources: 50+ styles, color palettes, font pairings, guidelines, charts for web/mobile across React, Next.js, Vue, Svelte, Tailwind, React Native, Flutter. Aids planning, building, reviewing interfaces.
Fetches up-to-date documentation from Context7 for libraries and frameworks like React, Next.js, Prisma. Use for setup questions, API references, and code examples.
Integrates PayPal payments with express checkout, subscriptions, refunds, and IPN. Includes JS SDK for frontend buttons and Python REST API for backend capture.
Automatically evaluates Claude Code sessions on end to extract reusable patterns that can be saved as learned skills.

/learn command - Manual pattern extraction mid-sessionHomunculus v2 takes a more sophisticated approach:
| Feature | Our Approach | Homunculus v2 |
|---|---|---|
| Observation | Stop hook (end of session) | PreToolUse/PostToolUse hooks (100% reliable) |
| Analysis | Main context | Background agent (Haiku) |
| Granularity | Full skills | Atomic "instincts" |
| Confidence | None | 0.3-0.9 weighted |
| Evolution | Direct to skill | Instincts → cluster → skill/command/agent |
| Sharing | None | Export/import instincts |
Key insight from homunculus:
"v1 relied on skills to observe. Skills are probabilistic—they fire ~50-80% of the time. v2 uses hooks for observation (100% reliable) and instincts as the atomic unit of learned behavior."
