February 2026 momentum centered on delivering a robust Agent Session Resume feature for google/adk-python and removing blockers to resume workflows. Key outcomes include delivering the Agent Session Resume Feature, enabling resume-only workflows by allowing resuming an agent session without sending a new message. The change required updating RunAgentRequest.new_message to Optional[types.Content] = None, eliminating the 422 Unprocessable Entity when resuming via the FastAPI web server. Delivered via commit 30b2ed3ef8ee6d3633743c0db00533683d3342d8 and linked to PRs addressing #4100 and #4185. Validation confirms RunAgentRequest validates without new_message and defaults to None. Impact: reduces friction for operators, accelerates session wake-ups, and supports smoother automation pipelines. Technologies/skills demonstrated include Python, FastAPI, Pydantic, and a PR-driven workflow with explicit type annotations and collaborator coordination.
