Nice, I have something similar [1], a super-fast Rust/Tantivy-based full-text search across Claude Code + Codex-CLI session JSONL logs, with a TUI (for humans) and a CLI/JSONL mode for agents.

For example there’s a session-search skill and corresponding agent that can do:

    aichat search —json  [search params]
