Experience Evolution — Knowledge Accumulation System

Current mode: Observe-Only Won't modify any files, only provides learning summary at session end.

What This Skill Does

Problem Scenarios

• Last week's API quota fix — forgot how to solve it this week
• Same TypeScript error recurring across different projects
• Performance optimization approach not recorded, hitting same bottleneck again
• Experience from one project can't be reused in another

Solution

Automatically remember your successes and failures:

1. After command execution: Record successful build/test/deploy commands
2. After bug fix: Capture effective solutions and debug paths
3. After optimization: Save benchmark data and improvement metrics
4. At session end: Generate learning summary, ask whether to save permanently

What Gets Observed

Command Execution (Bash)

• Successful build/test/deploy commands
• Failed commands and error messages
• Execution time (for performance comparison)

File Modifications (Write/Edit)

• Which files were modified
• Approximate scope (line count)
• Context (what feature was being worked on)

Working Directory

• Which project you're in
• Cross-project reusable patterns

Session End Learning Summary

Session Learning Summary

Project: your-project
Duration: 45 minutes
Commands: 15 (13 success, 2 failed)

Reusable Patterns Found:

1. API Retry Mechanism (High Value)
   Scenario: API QUOTA_EXCEEDED
   Solution: Exponential backoff retry (1s, 2s, 3s)
   Effect: 95% of rate limit errors auto-recover
   Reuse potential: All external API calls

2. TypeScript Type Fix (Medium Value)
   Scenario: Union type narrowing issues
   Solution: Type guard functions
   Effect: Eliminated 12 type errors
   Reuse potential: Medium (specific to current structure)

Save these learnings?
[y] Yes, save to knowledge base (confirm each)
[n] No, skip this time
[v] View details

Upgrade Path

Phase 1 (Current): Observe Only — No file writes, session-end summaries Phase 2: Write Logs — Record to learned/ directory, manual confirmation Phase 3: Semi-auto — Low-risk auto-save, high-risk needs confirmation Phase 4: Cross-project — Experience from project A auto-suggests in project B

Safety Commitment

Will never:

• Modify project source code
• Auto-commit to Git
• Modify package.json or config files
• Execute dangerous commands

Will only:

• Observe command execution results
• Record to isolated skill directory
• Require explicit approval before persisting
