Ultrawork Cancel Command

Session ID Handling

The session_id is provided by the hook via systemMessage as CLAUDE_SESSION_ID. You MUST pass it to the script via --session flag.

Execution

First, confirm with the user:

AskUserQuestion(questions=[{
  "question": "Cancel the current ultrawork session?",
  "header": "Confirm",
  "options": [
    {"label": "Yes, cancel", "description": "Mark session as cancelled, preserve history"},
    {"label": "No, continue", "description": "Keep working on current session"}
  ],
  "multiSelect": False
}])

If confirmed, execute the cancel script with --session:

"${CLAUDE_PLUGIN_ROOT}/scripts/ultrawork-cancel.sh" --session {SESSION_ID}

The script will:

• Update session.json phase to CANCELLED
• Preserve all history and evidence
• Allow starting a new session
