+## Comparison Notes (Research: Jan 2025)
+
+### vs Homunculus (github.com/humanplane/homunculus)
+
+Homunculus 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."
+
+### Potential v2 Enhancements
+
+1. **Instinct-based learning** - Smaller, atomic behaviors with confidence scoring
+2. **Background observer** - Haiku agent analyzing in parallel
+3. **Confidence decay** - Instincts lose confidence if contradicted
+4. **Domain tagging** - code-style, testing, git, debugging, etc.
+5. **Evolution path** - Cluster related instincts into skills/commands
