Looks good! The code follows best practices.

Augment Code Reviewbot3 hours ago

Using String(children) to derive heading IDs can return '[object Object]' when the heading contains inline elements (e.g., code/emphasis), leading to anchor mismatches with the TOC; consider extracting plain text from children (also applies to h2/h3).

Summary:

Introduces a new TUI modal and slash command to inspect configured agent hooks.

Changes:

  • •Adds a conditional slash command (gated byfeatureFlagsV2.enableHooks
  • •Implements hook with modal navigation (Esc to close, ↑/↓ or j/k to move)useHooksStatus
  • •Adds component to display hook event types, matchers, and commandsHooksStatusModal
  • •Integrates modal processor and visibility into alongside existing overlaysRepl
  • •Extends to register the action when availableuseSlashCommand/hooks

Technical Notes:

  • •Hook summary is computed from the hook manager state and groups config by HookEventType
  • •UI shows all six hook event types and details per type (matcher and associated commands)
  • •/hooks is hidden when the feature flag is disabled; modal participates in global input processing with priority 30
