2026-10-24-openhands-sessionstart-hooks-deliver-their-additional-context-to-the-agent
SessionStart hooks deliver their additional context to the agent. Collected SessionStart additionalContext is injected after the system-prompt event as a user-role message sourced from the environment. Previously returned startup context could be lost.
Channel: tagged-release. Half: capability. Date: 2026-10-22 (SDK v1.58.0).
Operator consequence: Retest hooks supplying project context before removing duplicate prompt injection. Delivery restores useful startup information; contextual text remains different from enforced policy.
