We renamed the configuration flag from store_tool_results to store_tool_messages and aligned behavior so tool-call and tool-result messages are scrubbed together. Metrics still capture token counts, preserving visibility while improving data hygiene and compliance controls. This is a breaking change — update your configuration to ensure consistent retention behavior.

**Details**

- Update config: store_tool_messages replaces store_tool_results
- Paired scrubbing ensures tool-call/result messages are removed together
- Metrics remain intact, preventing gaps in cost and usage reporting

**Who this is for:** Teams with strict data retention policies or regulated workloads that require consistent message scrubbing without losing operational metrics.
