feat(config): expose max_session_seconds in workflow YAML#31
Merged
Conversation
Allow workflow authors to tune the Copilot SDK session wall-clock timeout per-workflow (runtime.max_session_seconds) and per-agent (agent.max_session_seconds), instead of being locked to the hardcoded 1800s default. Per-agent values override the workflow-level default at call time, following the same pattern as agent.model. Closes #28 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
