+- [#577](https://github.com/perstack-ai/perstack/pull/577) [`17e5c92`](https://github.com/perstack-ai/perstack/commit/17e5c925ba0a12f2d828c133f021e56c4396392c) Thanks [@FL4TLiN3](https://github.com/FL4TLiN3)! - fix: add result param to attemptCompletion and remove GeneratingRunResult
+
+  - Add optional `result` string parameter to attemptCompletion tool schema so the LLM
+    can provide its final response text directly in the tool call
+  - Complete runs directly from CallingMcpTools when attemptCompletion succeeds, eliminating
+    the extra LLM round-trip in GeneratingRunResult
+  - Remove GeneratingRunResult state, its transitions, and the attemptCompletion event type
+  - Remove dead attemptCompletion event handling code from React event-to-activity utils
+  - Update E2E expert instructions to pass result via attemptCompletion args
+
