FAQPage Schema
How do I save session state without terminating an ongoing workflow?

To save session state without terminating your workflow, you can invoke a save function to update a checkpoint.json file with current context, next actions, and blocked items. This preserves progress midway through extended tasks.

What is the best way to log completed tasks during extended sessions?

The best way to log completed tasks during extended sessions is by comparing previous and current checkpoints. The system automatically records completed items into a history.jsonl file, creating a reliable audit trail of your progress.

Can I record an audit trail of progress using JSON and JSONL files?

Yes, you can record an audit trail using JSON and JSONL files. The process updates checkpoint.json for current session data and appends completed items to history.jsonl, ensuring data integrity and continuous history tracking.

When do I need to update a checkpoint file for workflow continuity?

You need to update a checkpoint file when working on complex projects that require frequent session snapshots. Saving progress midway prevents data loss and enables easy resumption and tracking without ending the session.

Does session snapshotting work without external dependencies?

Yes, session snapshotting works without external dependencies. The process relies entirely on internal JSON file updates and JSONL history tracking to automate the preservation of session states and ensure data integrity.

How do I track blocked items and next actions in a complex project session?

You can track blocked items and next actions by invoking the save function during your complex project. This updates the session state file with the latest status, capturing current context and pending tasks for easy resumption.
