ClaudeCode.Hook.DebugLogger (ClaudeCode v0.32.2)

A diagnostic hook that logs every invocation with event name, tool name, and available input keys. Returns :ok so it never interferes with normal execution.

Usage

Register it for any event types you want to observe:

{:ok, session} = ClaudeCode.start_link(
  hooks: %{
    PreToolUse: [ClaudeCode.Hook.DebugLogger],
    PostToolUse: [ClaudeCode.Hook.DebugLogger],
    Stop: [ClaudeCode.Hook.DebugLogger]
  }
)

For can_use_tool, use ClaudeCode.Hook.DebugLogger.Permissive which returns :allow instead of :ok:

{:ok, session} = ClaudeCode.start_link(
  can_use_tool: ClaudeCode.Hook.DebugLogger.Permissive
)
