Remove "When to Use" sections from skill content

[Copilot]

Skill invocation depends solely on the frontmatter description field. ## When to Use This Skill sections in skill content bodies are redundant with the description and add unnecessary tokens.

Changes

Skill authoring guidelines

• Removed When to Use This Skill from the Required Sections list in .github/instructions/skill-files.instructions.md

SKILL.md files (12 files) — removed ## When to Use This Skill / ## Skill Activation Triggers sections:

• azure-compliance, azure-kubernetes, azure-compute, azure-aigateway, azure-cost-optimization, azure-enterprise-infra-planner, appinsights-instrumentation, azure-resource-lookup, azure-quotas, azure-messaging
• microsoft-foundry/models/deploy-model/customize — section removed; Comparison: customize vs preset table preserved under its own heading
• microsoft-foundry/models/deploy-model/capacity

Reference/workflow files (11 files) — same removal applied to non-SKILL.md content that followed the same pattern:

• vm-recommender.md, create.md (foundry-agent), deploy.md, create-foundry-resource.md, trace.md, troubleshoot.md, invoke.md, eval-datasets.md, observe.md, aks-troubleshooting.md, rbac.md
• Warning/tip callouts that followed these sections (e.g., ⚠️ DO NOT manually call...) are preserved in place

Unit tests — updated assertions in 11 test files to remove checks for the deleted sections; a few tests updated to assert on equivalent content that remains (e.g., policy category table references instead of governance category labels that only existed in the removed sections)

Version bumps on all modified SKILL.md files per authoring conventions.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• centralus-2.in.applicationinsights.azure.com
  • Triggering command: /home/REDACTED/.npm/_npx/6027471c64e54353/node_modules/@azure/mcp-linux-x64/dist/azmcp /home/REDACTED/.npm/_npx/6027471c64e54353/node_modules/@azure/mcp-linux-x64/dist/azmcp server start git /.bin/npx ning-when-to-use --global /home/REDACTED/.cargo/bin/git -cost-optimizatiwatchman (dns block)
• https://api.github.com/copilot_internal/user
  • Triggering command: /opt/hostedtoolcache/node/24.14.0/x64/bin/node /opt/hostedtoolcache/node/24.14.0/x64/bin/node /home/REDACTED/work/GitHub-Copilot-for-Azure/GitHub-Copilot-for-Azure/tests/node_modules/@github/copilot/index.js --yolo --headless --no-auto-update --log-level error --stdio (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
