flex-search.md

Compiles your Claude Code session history for vector and hybrid retrieval. Your agent connects via MCP, discovers the schema at runtime, and writes SQL against your history — the full observable surface is searchable, including tool calls, file edits, agent delegations, and project attribution. Knowledge graphs build automatically from the data. Works retroactively — every past session becomes searchable on install.

Install

curl -sSL https://getflex.dev/install.sh | bash -s -- claude-code

Usage

After install, reload Claude Code and ask:

• "Use flex: what did we build this week?"
• "Use flex: what's the history of worker.py?"
• "Use flex: how did we set up the auth system?"
