Hooks are discovered from ~/.hermes/hooks/ directories, each containing: - HOOK.yaml (metadata: name, description, events list) - handler.py (Python handler with async def handle(event_type, context)) Events: - gateway:startup -- Gateway process starts - session:start -- New session created (first message of a new session) - session:end -- Session ends (user ran /new or /reset) - session:reset -- Session reset completed (new session entry created) - agent:start -- Agent begins processing a message - agent:step -- Each turn in the tool-calling loop - agent:end -- Agent finishes processing - command:* -- Any slash command executed (wildcard match) Errors in hooks are caught and logged but never block the main pipeline.
