Self Improving Agent

Self-Improving Agent

Captures learnings, errors, and corrections to enable continuous improvement across sessions.

Activation Triggers

This skill automatically activates when:

How It Works

1. Automatic Logging (via hooks)

PostToolUse → enhanced-failure-logger.js → logs failures with context
UserMessage → correction-detector.js → detects "wrong/actually/try again"
Response → capability-tracker.js → detects unfulfilled requests

2. Learning Aggregation

All learnings flow to logs/learnings.jsonl:

{
  "timestamp": "2026-01-26T12:00:00Z",
  "type": "user_correction|tool_failure|missing_capability",
  "category": "factual_error|command_failed|web_browsing",
  "description": "what was learned",
  "source": "which detector"
}

3. Session Start Review

On each session start, recent learnings are shown:

=== Learning Review ===
[Learnings] 47 total entries
[Recent]
  • [tool_failure] Bash failed: timeout - WebFetch to external API...
  • [user_correction] User corrected: "No, use the other file..."
[Corrections] 12 user corrections logged
[Capability Gaps] Top requested:
  • send emails (5x)
  • browse web (3x)

4. QAVR Integration

Successful learnings boost Q-values for related memories, improving future retrieval.

Manual Commands

Review Learnings

# Show all learnings
cat ~/.claude/logs/learnings.jsonl | tail -20

# Show corrections only
cat ~/.claude/logs/corrections.jsonl | jq -s 'group_by(.correction_type) | map({type: .[0].correction_type, count: length})'

# Show capability gaps report
node ~/.claude/scripts/hooks/capability-tracker.js --report

Test Detection

# Test correction detector
node ~/.claude/scripts/hooks/correction-detector.js

# Test failure logger
node ~/.claude/scripts/hooks/enhanced-failure-logger.js

# Test capability tracker
node ~/.claude/scripts/hooks/capability-tracker.js

Learning Categories

Correction Types

• factual_error - Wrong information provided
• retry_request - User asked to try again
• misunderstanding - Misinterpreted the request
• failed_solution - Solution didn't work

Failure Types

• permission_error - Access denied
• not_found - File/resource missing
• timeout - Operation timed out
• network_error - Connection issues
• syntax_error - Invalid syntax
• api_error - External API failed
• command_failed - Shell command failed
• agent_failed - Subagent failed

Capability Categories

• web_browsing - Internet access requests
• image_processing - Image/photo handling
• communication - Email/messaging
• database_access - SQL/database queries
• external_api - Third-party services
• memory_persistence - Long-term memory

Configuration

In settings.json, these hooks enable self-improvement:

{
  "hooks": {
    "SessionStart": [...],  // Reviews learnings
    "PostToolUse": [
      {"matcher": "Bash", "hooks": [{"command": "enhanced-failure-logger.js"}]},
      {"matcher": "Task", "hooks": [{"command": "enhanced-failure-logger.js"}]}
    ]
  }
}

Benefits

1. Learn from mistakes - Don't repeat the same errors
2. Understand user preferences - Track what corrections mean
3. Identify skill gaps - Know what features to build
4. Improve over time - QAVR ranking gets better with feedback
5. Context persistence - Learnings survive session restarts
