Exo developers need a reliable mechanism to observe, influence, and mutate agent executions without embedding logic in core components.
Register a simple START hook to log the event and demonstrate adding a tool during a run.

You can add observability to agent lifecycles by registering HookPoint interceptions across events like START, PRE_LLM_CALL, and FINISHED to monitor runs externally without modifying core logic.
Yes, you can dynamically mutate tools, handoffs, and MCP servers during a live agent run by using runtime mutation methods and ephemeral message injection via async hooks.
Available lifecycle events for interception include START, PRE and POST LLM_CALL, PRE_TOOL_CALL, FINISHED, ERROR, and CONTEXT_WINDOW, enabling precise control across execution stages.
Register a simple START hook via the HookManager API to log the event and demonstrate adding a tool during a run, applying async hook safety semantics for reliable execution.
Use hookpoints to build safety rails when you need to intercept PRE_TOOL_CALL or ERROR events, allowing you to block unsafe actions or inject corrective context dynamically during execution.
Yes, runtime mutations across agent runs require async hooks to ensure safety semantics and non-blocking execution when intercepting lifecycle events or mutating tools dynamically.
