Remembering Conversations

Search archived conversations using semantic similarity or exact text matching.

Core principle: Search before reinventing.

Announce: "I'm searching previous conversations for [topic]."

Setup: See INDEXING.md

When to Use

Search when:

• Your human partner mentions "we discussed this before"
• Debugging similar issues
• Looking for architectural decisions or patterns
• Before implementing something familiar

Don't search when:

• Info in current conversation
• Question about current codebase (use Grep/Read)

In-Session Use

Always use subagents (50-100x context savings). See skills/getting-started for workflow.

Manual/CLI use: Direct search (below) for humans outside Claude Code sessions.
