Review CLAUDE.md from conversation history

Analyze recent conversations to improve both global (~/.claude/CLAUDE.md) and local (project) CLAUDE.md files.

Step 1: Find conversation history

The project's conversation history is in ~/.claude/projects/. The folder name is the project path with slashes replaced by dashes. bash

Find the project folder (replace / with -)

PROJECT_PATH=$(pwd | sed 's|/|-|g' | sed 's|^-||') CONVO_DIR=~/.claude/projects/-${PROJECT_PATH} ls -lt "$CONVO_DIR"/*.jsonl | head -20

Step 2: Extract recent conversations

Extract the 15-20 most recent conversations (excluding the current one) to a temp directory: bash SCRATCH=/tmp/claudemd-review-$(date +%s) mkdir -p "$SCRATCH" for f in $(ls -t "$CONVO_DIR"/*.jsonl | head -20); do basename=$(basename "$f" .jsonl)

Skip current conversation if known

cat "$f" | jq -r ' if .type == "user" then "USER: " + (.message.content // "") elif .type == "assistant" then "ASSISTANT: " + ((.message.content // []) | map(select(.type == "text") | .text) | join("\n")) else empty end ' 2>/dev/null | grep -v "^ASSISTANT: $" > "$SCRATCH/${basename}.txt" done ls -lhS "$SCRATCH"

Step 3: Spin up Sonnet subagents

Launch parallel Sonnet subagents to analyze conversations. Each agent should read:

• Global CLAUDE.md: ~/.claude/CLAUDE.md
• Local CLAUDE.md: ./CLAUDE.md (if exists)
• Batch of conversation files Give each agent this prompt template:

Read:

1. Global CLAUDE.md: ~/.claude/CLAUDE.md
2. Local CLAUDE.md: [project]/CLAUDE.md
3. Conversations: [list of files] Analyze the conversations against BOTH CLAUDE.md files. Find:
4. Instructions that exist but were violated (need reinforcement or rewording)
5. Patterns that should be added to LOCAL CLAUDE.md (project-specific)
6. Patterns that should be added to GLOBAL CLAUDE.md (applies everywhere)
7. Anything in either file that seems outdated or unnecessary Be specific. Output bullet points only.

Batch conversations by size:

• Large (>100KB): 1-2 per agent
• Medium (10-100KB): 3-5 per agent
• Small (<10KB): 5-10 per agent

Step 4: Aggregate findings

Combine results from all agents into a summary with these sections:

1. Instructions violated - existing rules that weren't followed (need stronger wording)
2. Suggested additions - LOCAL - project-specific patterns
3. Suggested additions - GLOBAL - patterns that apply everywhere
4. Potentially outdated - items that may no longer be relevant Present as tables or bullet points. Ask user if they want edits drafted.

Troubleshooting

Conversation history is empty or too few files: Check the project path mapping (slashes → dashes). If the user started with a different project path, the folder name won't match. Subagents return conflicting recommendations: Prioritize by frequency — if 3+ agents flag the same pattern, it's a strong signal. Unique findings need manual user review. CLAUDE.md is already well-optimized: Focus on Step 4 "potentially outdated" items. Even good configs accumulate stale rules over time.
