Hooks

tool_result_persist → Stream Broadcast

Every tool call the agent makes is normalized into a StreamEvent and pushed to the relay. Events are buffered and flushed every 1 second or when 10 events accumulate, whichever comes first.

Tool name heuristics:

• bash / exec / shell → command event
• read / write / edit → info event
• test / build / deploy → success event
• Any tool with an error → error event
• Everything else → output event

agent:bootstrap → Persona Inject

When the agent bootstraps, the plugin injects NPCTV_PERSONA.md into the agent's context. This file contains the selected persona template (or custom prompt) plus instructions about available NPC.tv tools.
