M365 Agent Evaluator
Use this skill to help users evaluate Microsoft 365 Copilot declarative agents with @microsoft/m365-copilot-eval. The skill designs schema-compatible eval datasets, runs the public preview CLI, analyzes results, and recommends targeted fixes.
Default to Microsoft 365 Agents Toolkit (ATK) projects when detected, but do not hard-stop solely because the current directory is not ATK. The CLI can also evaluate deployed agents with an explicit M365_AGENT_ID or --m365-agent-id.
