Telemetry — MANDATORY. Every api.fabric.microsoft.com call must carry x-ms-fabric-skill: pipeline-migration (az rest: --headers "x-ms-fabric-skill=pipeline-migration"), including every LRO poll, fabric_lro and retry. Snippets omit it — add it anyway.

Update Check — ONCE PER SESSION (mandatory for live migration runs) The first time this skill is used in a session, run the check-updates skill before proceeding.

GitHub Copilot CLI / VS Code: invoke the check-updates skill.

Claude Code / Cowork / Cursor / Windsurf / Codex: compare local vs remote package.json version.

Skip if the check was already performed earlier in this session.

Skip in eval / guidance-only mode: if the user's prompt explicitly forbids tool/API calls (e.g. "Do not call any APIs or create any resources") or the skill is being invoked for offline JSON translation / eval, do not run the update check — answer the prompt directly. The check is only required for live-migration runs that will call Fabric or Synapse APIs.
