Research direction

The failure is in the Start MCP Gateway step of the agent job in the linked run, and the issue does not record a cause. Start with the failed step's logs in that run and the workflow source at .github/workflows/smoke-codex-auto.md, then trace how the gateway is started. Done means the gateway step succeeds and the agent execution begins, which the maintainers would need to confirm.

Description

agentic-workflows cascade-suspected
Workflow Failure

Workflow: Smoke Codex Auto
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/38657841610

[!WARNING]
Task Could Not Be Completed: The workflow recorded a report_incomplete signal: the task was not completed or completion could not be confirmed.

Error details: 
Failure classification: agent_startup_failure
Agent execution state: not_started
The runtime recorded that agent execution never started. Inspect the failed startup step and gateway/setup logs in the linked run; missing safe outputs are downstream, not evidence that the agent omitted a terminal output.

A comment or other safe output does not confirm that the requested task was completed. Only inferred runtime status and error codes are reported; agent text is excluded.

Failure Diagnostics

Agent job: agent
Agent job conclusion: failure
Failing step: Start MCP Gateway

The runtime did not record a specific cause. Check the linked run for failure details.

Only runtime metadata is shown; agent-generated text is excluded.
