apollo-upgrade-migration

The skill's footprint is coherent with a developer-focused Apollo API upgrade/migration workflow. It includes auditing, a compatibility shim, a feature-flag rollout, parallel verification, and rollback procedures. There are no evident credential-harvesting or unauthorized data-exfiltration patterns; the data flows are confined to internal codebase analysis, API calls to Apollo, and deployment tooling. Some surface area risk exists around maintaining the compatibility layer and rollout configuration correctness, but overall the design is proportionate to its stated purpose.
