+# Todo 21 EventAgent Context Summary Plan
+
+**Status:** in_progress
+
+## Goal
+
+Make EventAgent configuration part of tool-parameter generation and send a combined EventAgent result summary into the ChatAgent input queue.
+
+## Why
+
+The UI and contracts already expose EventAgent `system_prompt` and `extra_body`, but parameter generation currently only receives event/history. Also, individual tool replies are provider-compatible, but ChatAgent should get a concise aggregate result from EventAgent after all tools in the current event round finish.
+
+## Scope
+
+- Add an EventAgent execution context containing history, system prompt, and extra body.
+- Pass EventAgent config from `DebugRuntime` into `EventAgentRequest`.
+- Keep individual `tool` replies for Chat Completions compatibility.
+- Add one aggregate `user` message after tool replies so the next ChatAgent round sees the combined EventAgent result.
+
+## Verification
+
+- EventAgent tests prove custom resolvers receive `system_prompt` and `extra_body`.
+- Runtime tests prove the second ChatAgent round contains tool replies followed by the aggregate summary.
+- Full suite passes with `uv run pytest`.
