Fast Path

casr list
casr info <session-id>
casr -cc <session-id>   # open in Claude Code
casr -cod <session-id>  # open in Codex
casr -gmi <session-id>  # open in Gemini

Helpful Commands

casr providers
casr list --workspace "$(pwd)" --sort date --limit 20
casr cod resume <session-id> --source cc

Notes

casr list is project-scoped to your current working directory by default.
-cc, -cod, and -gmi auto-detect source provider from the session ID.
Use --json output mode for automation.
