Pin Agentic Triage to a supported Copilot model

[Copilot]

Agentic Triage failed when repository or organization defaults selected a model unavailable to the agentic-workflows integration.

• Workflow configuration

  • Pin the Copilot engine to claude-sonnet-5.
  • Prevent external model defaults from overriding the workflow.

• Generated workflow

  • Regenerate issue-triage.lock.yml with the pinned model.

• Fixes [aw] Agentic Triage failed #11808

🟡 Changes recommended

The workflow is pinned to gpt-5, which appears not to be available for the agentic-workflows integrator per the linked failure output, so the triage run may continue failing and the lock file should be regenerated after correcting the pinned model.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR updates the Agentic Triage workflow configuration to pin the Copilot engine/model so repository/org defaults can’t select an unsupported model, and regenerates the compiled lock workflow accordingly.

Changes:

• Switch .github/workflows/issue-triage.md from engine: copilot to an explicit engine.id + engine.model configuration.
• Regenerate .github/workflows/issue-triage.lock.yml to hard-code the selected model in the compiled workflow (replacing prior ${{ vars... }} fallback logic).

File summaries

File	Description
.github/workflows/issue-triage.md	Pins the Agentic Triage workflow’s engine/model in frontmatter.
.github/workflows/issue-triage.lock.yml	Regenerated compiled workflow reflecting the pinned model (and removing variable-based overrides).

• This is pinned to gpt-5, but the failure issue’s error output lists models available to the agentic-workflows integrator and it does not include gpt-5 (it does include claude-sonnet-5). After changing the source workflow to a supported model, regenerate the lock file so all model fields match.

• COPILOT_MODEL is pinned to gpt-5, but the failure issue’s error output indicates gpt-5 is not available for the agentic-workflows integrator. This should be updated to a supported model (e.g. claude-sonnet-5) by regenerating the lock file from the source workflow.

• GH_AW_ENGINE_MODEL is hard-coded to gpt-5, but the failure issue’s error output suggests gpt-5 is not available for the agentic-workflows integrator (while claude-sonnet-5 is). Regenerate the lock file after updating the pinned model so the exported summary matches the actual supported model.

• The detection phase also pins COPILOT_MODEL to gpt-5, which (per the failure issue’s model availability list) is not available for the agentic-workflows integrator. Regenerate the lock file after switching to a supported model to avoid detection failures.

Copilot address review comments

Addressed in 2555add: Agentic Triage now pins claude-sonnet-5, and its lock file was regenerated with gh-aw v0.80.9.

[Copilot]

🟢 Approval recommended

The workflow now deterministically uses a supported Copilot model and the regenerated lock file consistently reflects that pinning without remaining override paths.
