[Pilot] PR Pipeline Failure Analysis

A CI pipeline failed on this pull request. Here is an automated analysis of what went wrong and how to get the build green.

What failed

The sync-.github-skills pipeline validation failed because this PR modifies files under the eng/common/ directory (eng/common/knowledge/eval-authoring/README.md and eng/common/pipelines/skill-eval.yml). Changes to eng/common are not allowed in this repository — they must be made in the upstream azure-sdk-tools repo and then synced in.

Build #6614359

Recommended next steps

• Remove the changes to eng/common/knowledge/eval-authoring/README.md and eng/common/pipelines/skill-eval.yml from this PR.
• Submit those changes to Azure/azure-sdk-tools following the common engineering system workflow.
• Once the changes are synced to this repo via the normal eng/common sync process, they will appear here automatically.
• See the CI troubleshooting guide: https://aka.ms/ci-fix
• Push new commits to address the failures; this comment updates automatically on the next failing run.
