dicklesworthstone/coding_agent_session_search

If you're bouncing between Claude Code, Cursor, Aider, and other coding agents, your conversation history is scattered across different formats and locations. This indexes all of it into one searchable database with a fast CLI. The key thing to know: always use `--robot` or `--json` flags when calling it from an AI agent, because the bare command launches an interactive TUI that will block your session. It's built for cross-agent knowledge transfer, like searching "how did I fix that auth bug last month" across every coding assistant you've used. Supports 11 agents out of the box and can sync sessions from remote machines over SSH.

CASS - Coding Agent Session Search

Unified, high-performance CLI/TUI to index and search your local coding agent history. Aggregates sessions from 23 agents, including Codex, Claude Code, Gemini CLI, Cline, OpenCode, Amp, Cursor, ChatGPT, Aider, Pi-Agent, Factory (Droid), OpenHands, Antigravity, and Grok Build.

CRITICAL: Robot Mode Required for AI Agents

NEVER run bare cass - it launches an interactive TUI that blocks your session!

# WRONG - blocks terminal
cass

# CORRECT - JSON output for agents
cass search "query" --robot
cass search "query" --json  # alias

Always use --robot or --json flags for machine-readable output.

Quick Reference for AI Agents

Bounded History Retrieval

For a quick project-history question, start with one scoped query. The flag set below is verified on cass 0.8.0; check cass --version and cass search --help once per installed version. If --no-maintenance is unsupported, stop and report the version mismatch; silently removing it permits maintenance.
