Pull Request Overview
This PR fixes the session resumption logic in the Claude Code module by implementing proper detection of existing sessions before attempting to resume them. The key change is adding a has_session_for_workdir() function that checks for valid user messages in session history, and modifying the startup logic to use the continue flag to intelligently decide whether to resume an existing session or start fresh.
Key changes:
- Adds session detection logic that validates actual user interaction history before attempting to resume
- Updates the
continuevariable default fromfalsetotruewith improved documentation - Refactors startup script to handle three scenarios: explicit resume, conditional continue based on session existence, and fresh start

I see the logic is tightly coupled with the internal file structure of claude. I think it'd be more robust to rely on claude --session-id <uuid> and claude -r <uuid>.
You could choose a predefined uuid such as cd32e253-ca16-4fd3-9825-d837e74ae3c2 for the task session. Before starting claude, first run
find "$HOME/.claude" -type f -name "*cd32e253-ca16-4fd3-9825-d837e74ae3c2*"to see if there are any sessions with this id in the workspace. If there are, use claude -r, if there are none, use --session-id.
This approach also avoids buggy behavior with user-spawned claude sessions in the workspace. --continue opens the last-used session, --session-id and -r would always open the same task session.
… to validate session resumption
I ironically just had the same thought and switched over to extracting the latest session with actual user messages in it, but defining the session id is a much better solution. I will make the change now. |

Everything works well with session resumption now. |
