Learned Patterns Management

Manage the auto-learning pattern library. View, list, archive, and adjust confidence.

Summary

Goal: View, list, archive, boost, or penalize learned patterns in the auto-learning pattern library.

• List patterns: node scripts/list-patterns.cjs [category] [--low|--high]
• View details: node scripts/view-pattern.cjs <id>
• Adjust confidence: node scripts/adjust-confidence.cjs <id> boost|penalize (+10% / -15%)
• Archive: node scripts/archive-pattern.cjs <id> [reason]
• Stats: node scripts/pattern-stats.cjs

Key Principles:

• Patterns auto-decay after 30 days unused; below 20% confidence = auto-archived
• Lifecycle: Detection (40-80%) -> Confirmation -> Injection -> Feedback Loop -> Decay
• Max 5 patterns injected per context (~400 tokens)

Quick Commands

/learned-patterns                    # List all active patterns
/learned-patterns list [category]    # List patterns (optionally filtered)
/learned-patterns list --low|--high  # Filter by confidence
/learned-patterns view <id>          # View pattern details
/learned-patterns archive <id>       # Archive a pattern
/learned-patterns boost <id>         # Increase confidence (+10%)
/learned-patterns penalize <id>      # Decrease confidence (-15%)
/learned-patterns stats              # Show pattern statistics

Script Execution

Pattern Lifecycle

DETECTION (UserPromptSubmit)
  └── Confidence: 40% (implicit) or 80% (explicit /learn)

CONFIRMATION
  └── User confirms → saved | User rejects → discarded

INJECTION (SessionStart/PreToolUse)
  └── Relevant patterns injected (max 5, ~400 tokens)

FEEDBACK LOOP
  └── Followed → +5% | Ignored → -10%

DECAY & PRUNING
  └── 30 days unused → decay | Below 20% → auto-archived

content:
  wrong: "throw new ValidationException()"
  right: "return PlatformValidationResult.Invalid()"

Troubleshooting

• Not injecting: Check confidence, file pattern match, archived status
• Too many injecting: Archive irrelevant patterns, review --low confidence list
• Conflicts with docs: Pattern auto-blocked; update docs or archive pattern

IMPORTANT Task Planning Notes

• Always plan and break many small todo tasks
• Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
