What Create Adapter does

Create Adapter covers building conversation adapters that import AI chat history from tools like Claude Code, Cursor, Warp, and Codex. Use it when creating or debugging an adapter’s parsing, caching, watch handling, or performance behavior.

Create Adapter is cataloged under AI Engineering on DirSkills. Create Adapter comes from a repository tagged agentic-ai, agentic-workflows, claude-code and tui.

Create Adapter

Why Performance Matters

Adapters are the largest performance risk in Sidecar. Conversations refresh on watch events in a hot path that runs continuously during active sessions:

watch event -> coalescer -> session refresh -> adapter.Sessions() -> metadata parsing

If an adapter does full directory scans and full-file reparses on every change, CPU and FD usage spike quickly.

Reference Adapters

This is the opening of the README. Read the full README on GitHub.
