Self-Improvement - Learn from History

Analyze Claude Code conversation history to find friction patterns, check what's already fixed, and suggest improvements.

Instructions

Phase 1: Find Conversations

# Get project directory (encode current path with dashes)
ls ~/.claude/projects/

# List today's conversations (or adjust -mtime for longer range)
ls -lt ~/.claude/projects/<encoded-path>/*.jsonl | head -20

Phase 2: Parallel Analysis

Spawn Task agents (subagent_type: general-purpose) to analyze conversations in parallel. Each agent reads one .jsonl file and extracts:

1. What was user trying to accomplish?
2. Problems/friction that occurred (include user quotes showing frustration)
3. What worked well?
4. Repeated patterns or inefficiencies

For large files (>500KB), prioritize those - they contain the meatiest sessions.

Phase 3: Synthesize

After all agents complete, combine findings:

• Top friction patterns ranked by frequency
• What worked well (don't lose these)
• User frustration quotes (raw evidence)

Generalize aggressively. Look for the meta-pattern behind specific issues.

Phase 4: Cross-Reference

Read current documentation:

• Project CLAUDE.md
• User ~/.claude/CLAUDE.md
• Skills in .claude/skills/ and ~/.claude/skills/

For each friction pattern, classify:

• Already fixed - note location
• Still missing - needs addition

Phase 5: Output

Create a markdown file (e.g., CLAUDE_IMPROVEMENTS.md) with:

# Suggested CLAUDE.md Improvements

Based on analysis of N conversations from [date range].

## 1. [Issue Name]

**Problem:** [Description of friction]

**Suggested addition to [location]:**

## Already Fixed

## Potential Skills

## Raw Friction Log

- "user quote 1"
- "user quote 2"

Do not apply changes - create the file for user review.
