feat: Evolution and learning system for Pichu

[jeffwweee]

Feature Request

Add an evolution and learning system to Pichu that can learn from sessions and evolve into better patterns.

Background

Reference: everything-claude-code (ecc) has a sophisticated learning system with:

v1: Stop Hook Learning

• Evaluates sessions at end (10+ messages)
• Extracts patterns: error_resolution, user_corrections, workarounds, debugging_techniques
• Saves to ~/.claude/skills/learned/

v2: Instinct-Based Learning

• PreToolUse/PostToolUse hooks - 100% reliable observation
• Atomic instincts - one trigger, one action with confidence scoring (0.3-0.9)
• Project-scoped - prevents cross-project contamination
• Evolution path - instincts → cluster → skill/command/agent
• Commands: /instinct-status, /evolve, /instinct-export, /instinct-import, /promote

Instinct Model

id: prefer-functional-style
trigger: "when writing new functions"
confidence: 0.7
domain: "code-style"
source: "session-observation"
scope: project

Proposed Implementation for Dev Workspace

Phase 1: Observation Layer

• Add hooks to observe Telegram conversations
• Capture: user corrections, successful patterns, error resolutions
• Store observations in state/learning/observations.jsonl

Phase 2: Instinct System

• Create instinct extraction from observations
• Implement confidence scoring
• Store instincts in state/learning/instincts/
• Add domain tagging (telegram, git, debugging, workflow)

Phase 3: Evolution

• Cluster related instincts
• Generate skills from clusters
• Auto-update Commander with learned behaviors
• /evolve command via Telegram

Phase 4: Memory Integration

• Update state/memory/knowledge/ from learned patterns
• Persist high-confidence instincts across sessions
• Export/import learning with other workspaces

Commands to Add

Command	Description
/learn-status	Show learned instincts and confidence
/evolve	Cluster instincts into skills
/learn-export	Export learning data
/learn-import	Import learning from another workspace

Benefits

• Pichu gets smarter over time
• Learns user preferences automatically
• Reduces repetitive corrections
• Evolves with the project
