Workflow Failure

Workflow: Runtime Failure Observer (xharness)
Branch: main
Run: https://github.com/dotnet/xharness/actions/runs/34423131731

Warning

Missing Tools Reported: The agent reported missing tools during execution.

Missing Tools:

• gh: gh: To use GitHub CLI in a GitHub Actions workflow, set the GH_TOKEN environment variable. Example: env: GH_TOKEN: $\{\{ github.token }}

Alternatives:

Tool	Alternative
gh	No permitted authenticated GitHub read tool is available in this runtime; GitHub MCP tools were required by the workflow but are not exposed to this agent.

Warning

Engine Failure: The copilot engine terminated unexpectedly.

Last agent output:

The scan is incomplete: the required xharness fix-dedup search could not run because `gh` has no authentication token, and no authenticated GitHub read tool is exposed in this environment. I reported the unavailable required tool; no pull request or no-op result was emitted.
