1. Check Execution State

Read .frink/state.json:

json

{
  "execution_state": "running",
  "current_task": "3.5",
  "current_session_type": "executor"
}

If not running:

code

2. Confirm Cancellation

code

- Progress: 32/85 tasks (37.6%)
- Session: Executor #32 (in progress)

WARNING: Cancelling will:
- Terminate the current session
- Leave task 3.5 incomplete
- Preserve all completed work

Any uncommitted changes from the current session
may need manual review.

Confirm cancel? [y/N]

3. Terminate Current Session

If a session is running:

•Send interrupt signal to Claude CLI process
•Allow graceful shutdown (5s timeout)
•Force kill if needed

4. Update State

Update .frink/state.json:

json

{
  "execution_state": "cancelled",
  "cancelled_at": "2026-01-22T11:30:00Z",
  "cancel_reason": "Need to restructure the task list",
  "last_completed_task": "3.4",
  "incomplete_task": "3.5"
}

5. Generate Cancel Report

code

Execution CANCELLED

Reason: Need to restructure the task list
Cancelled at: 2026-01-22 11:30:00 AM

Summary:
- Tasks Completed: 32/85 (37.6%)
- Last Completed: 3.4 Configure local DynamoDB
- Incomplete: 3.5 Set up local S3 (LocalStack)

Preserved State:
- All completed work committed to git
- State saved in .frink/state.json
- Logs available in .frink/logs/

To resume from last completed task:
  /professor-frink:run

To restart from a specific task:
  /professor-frink:run --from 3.5

To reinitialize completely:
  /professor-frink:init --reset

Recovery Options

After cancellation:

•Resume: Run /professor-frink:run to continue from last completed task
•Restart Task: Run /professor-frink:run --from 3.5 to retry the incomplete task
•Reset: Run /professor-frink:init --reset to start over (preserves code, resets state)
•Manual Fix: Review .frink/logs/session-* for the incomplete session

If normal cancel doesn't work:

code

/professor-frink:cancel --force

This will:

•Immediately kill any running processes
•Mark state as force_cancelled
•May leave working directory in inconsistent state
•Requires manual cleanup
