[aw] Smoke Codex failed

[github-actions]

Workflow Failure

Workflow: Smoke Codex
Branch: copilot/add-codex-engine-support
Run: https://github.com/github/gh-aw/actions/runs/32612785481
Pull Request: #54606

Warning

Invalid or Unsupported Model: The agent failed because the configured model name is invalid, unknown, or unavailable for this engine/account.

This is a configuration issue, not a transient error — retrying will not help.

How to fix this

Specify a valid model for the selected engine in the workflow frontmatter:

---
engine: copilot
model: gpt-5-mini
---

To find valid models, check your engine/provider documentation (for Copilot see supported models).

If the error text is No model available. Check policy enablement under GitHub Settings > Copilot, the model is not disabled in the workflow but by Copilot policy. Enable the model under GitHub Settings > Copilot > Policies for the org/repo, or pick a model that is already enabled. This can also be triggered by a subagent (task tool) dispatch requesting a model that the policy does not allow, even when the main agent's model is enabled.

Warning

Engine Failure: The codex engine terminated unexpectedly.
