Recommended action: Make the hook print exactly one JSON object on stdout (send diagnostics to stderr), return an explicit allow/deny decision, and keep it under its timeout; only set failClosed: true when you want blocking on failure.
Option: Make the hook print exactly one JSON object on stdout (send diagnostics to stderr), return an explicit allow/deny decision, and keep it under its timeout; only set failClosed: true when you want blocking on failure. [evidence: official_recommended_action]
Applies when: Command hook configured on a permission step (beforeShellExecution, beforeMCPExecution, beforeReadFile, beforeTabFileRead, subagentStart, preToolUse)
Steps:
1. Run the hook manually with a sample payload and pipe stdout through a JSON validator.
2. Redirect all logging to stderr.
3. Check the agent log for "Hook script timed out after".
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
