Claude Historian

Search your conversation history before starting new work.

When to Use

I'm stuck, what have I tried before?

• Error with no obvious cause → get_error_solutions
• Trying different approaches → find_tool_patterns
• Working on familiar file → find_file_context

This might be solved already

• Before WebSearch → find_similar_queries
• Starting old project → list_recent_sessions
• Need design reasoning → search_plans

I need specific information

• General history search → search_conversations
• Session summary → extract_compact_summary

Best Practice

Check historian BEFORE:

• WebSearch (you may already know this)
• Asking clarifying questions (past context helps)
• Starting implementation (past approaches may apply)
