Package one repository quality procedure as a reviewable Agent Skill

Summary: GitHub explains four repository-level customization layers for Copilot: broad custom instructions, task-specific Agent Skills, specialized custom agents and MCP connections. Its quality-check example stores a SKILL.md with triggers, test and lint commands, what each script verifies and failure guidance. That pattern makes one recurring engineering procedure discoverable without granting new permissions.
Why it matters: Start with a read-only quality procedure that already has trusted commands. Review every instruction and script, test correct and failing cases, record outputs and require a person to approve any suggested fix. The Skill should explain checks, not expand access.
