DNA Evolution - Continuous Learning System

Mission

Capture patterns from interactions to evolve Arthur's Cognitive DNA profile. The goal is 1+1 = exponential — learned patterns compound across sessions rather than starting fresh.

Activation

Always active. Monitors interactions for learning signals and updates DNA profile.

Learning Triggers

Explicit Feedback

• User says "that worked well" → Reinforce pattern
• User says "don't do that" → Mark as anti-pattern
• User rates session → Update feedback log
• User expresses preference → Capture to preferences

Implicit Signals

• Correction received → Pattern was wrong, adjust confidence
• Approach succeeded → Reinforce with evidence
• Same question repeated → Explanation wasn't clear
• User simplified request → Original was over-engineered

Pattern Recognition

• Technology choice praised → Strengthen preference
• Methodology worked → Increase confidence
• Integration succeeded → Document working pattern
• Error resolved → Capture resolution pattern

DNA Profile Structure

Location: .claude/context/cognitive-dna/arthur-dna-profile.json

What Gets Updated

Evolution Tracking

Every significant update creates a snapshot:

• Location: .claude/context/cognitive-dna/snapshots/
• Format: {timestamp}-{trigger}.json
• Contains: Full profile at that point

Learning Actions

On Positive Feedback

# Pseudocode
pattern = identify_pattern(feedback)
if pattern in profile.strengths:
    profile.strengths[pattern].confidence += 0.01
    profile.strengths[pattern].evidence += 1
else:
    add_emerging_strength(pattern)

On Correction

# Pseudocode
wrong_pattern = identify_pattern(correction)
if wrong_pattern in profile.strengths:
    profile.strengths[wrong_pattern].confidence -= 0.02
if needs_augmentation(wrong_pattern):
    add_to_limitations(wrong_pattern)

On Session End

# Pseudocode
session = {
    "id": generate_id(),
    "timestamp": now(),
    "activity": summarize_session(),
    "highlights": extract_highlights(),
    "technologies": extract_technologies(),
    "rating": infer_or_ask_rating()
}
profile.feedback.sessions.append(session)

Gap Augmentation

When a limitation is detected, proactively compensate:

Integration with HETA

DNA patterns inform branch expert behavior:

Backend Expert

• Apply: Sequential problem-solving, validation emphasis
• Augment: Security considerations, performance profiling

Frontend Expert

• Apply: Code examples, detailed explanations
• Augment: React/Vue best practices (lower confidence area)

Infrastructure Expert

• Apply: DevOps patterns (high confidence: 73.7%)
• Augment: Security hardening

Commands

/dna-status

Show current DNA profile summary

/dna-learn {pattern}

Explicitly capture a new pattern

/dna-feedback {rating} {note}

Record session feedback

/dna-snapshot

Force create a snapshot of current profile

Persistence

On Every Significant Change

1. Update arthur-dna-profile.json
2. Create snapshot if major change
3. Update important-context.md if critical

Snapshot Triggers

• 5+ evidence points added to single strength
• New limitation identified
• Confidence shift > 5%
• Explicit user request

Success Metrics

• Patterns from session N improve session N+1
• Corrections decrease over time
• High-confidence areas produce consistently positive feedback
• Augmented gaps show improvement

DNA Evolution ensures every interaction makes the next one better.
