ELF Session Search Command

Search through Claude Code session history using natural language queries.

Purpose

The /search command helps you find:

  • Previous prompts and conversations
  • Work on specific topics
  • Files modified in past sessions
  • Context from earlier iterations
  • Related discussions across sessions

Usage Examples

/search what was my last prompt?
/search what was I working on yesterday?
/search find prompts about git
/search show me recent conversations
/search where did I edit the router?

How It Works

When you invoke /search:

  1. Extract your query from the command
  2. Search session logs - Parse JSONL files from ~/.claude/projects/
  3. Find matches - Natural language matching against user messages
  4. Show results - Display relevant prompts and context
  5. Answer your question - Use results to provide context

Session Log Format

Session data is stored in:

  • Location: ~/.claude/projects/[project-name]/*.jsonl
  • Format: Line-delimited JSON with message objects
  • Content: User prompts and Claude responses
  • Indexed: Most recent files first (by mtime)

Each JSONL file contains:

  • type: "user" - Your prompts
  • type: "assistant" - My responses
  • Skips: Subagent logs (agent-*.jsonl)

Implementation Steps

  1. Scan session directory: ls -t ~/.claude/projects/*/*.jsonl
  2. Skip agent logs: Filter out agent-*.jsonl
  3. Read JSONL: Parse JSON line-by-line
  4. Extract messages: Filter for "user" and "assistant" types
  5. Search: Match your query against content
  6. Display: Show matching prompts with context

Search Capabilities

  • Topic search - Find discussions about specific subjects
  • Temporal search - Find work from yesterday, last week, etc.
  • File-based search - Find when you last edited a file
  • Tool search - Find when you used specific tools
  • Pattern search - Find similar problems or approaches

Integration with ELF

The search command integrates with the building's session summaries. After search:

  • Relevant heuristics might be suggested
  • Related failures/successes found
  • Continuous context preserved

This helps you avoid repeating past mistakes and leverage previous insights.

Search Tips

  • Use specific keywords - "router" not just "code"
  • Try natural language - System understands intent
  • Include context - "when I worked on auth" not just "auth"
  • Check timeframe - Session logs are dated
