## Session Isolation

All hook changes are session-scoped. Disabling a hook only affects the current session and does not persist.

## Profiling

- Red alert: execution time > 5s
- Yellow warning: execution time > 3s
- Green: execution time < 3s
- Output size monitoring: flag > 10KB

## Commands

- `/hook:enable [hookName]` -- Enable a disabled hook
- `/hook:disable [hookName]` -- Disable a hook for this session
- `/hook:status` -- Show all hook states and profiling data

## When to Use

- When a hook is causing issues during a session
- To check performance of hook executions
- To temporarily bypass a hook for a specific operation

## Processes Used By

- `claudekit-orchestrator` (hook pipeline setup)
- `claudekit-safety-pipeline` (hook profiling)
