What problem does it solve? Migrating a Cursor Cloud Agent environment to prebuilt environment builds can break setup when install, start, and terminals phases are misconfigured. This Skill tests build compatibility, classifies configuration sources, and recommends the exact changes needed before enabling builds. ## Core Features & Use Cases - Build Compatibility Testing: Validates that the current Cloud Agent environment works with prebuilt environment builds before the user enables them on the Builds tab. - Phase Classification: Diagnoses misplaced setup work by classifying each action into install (durable repository setup), start (per-boot initialization), or terminals (long-running foreground processes). - Configuration Precedence Resolution: Determines whether the effective environment configuration comes from .cursor/environment.json, a personal saved environment, or a team saved environment. - Use Case: A team's Cloud Agent loses its dev server after every snapshot restore. The Skill identifies that the server was started in install, recommends moving it to terminals, and validates the fix with a build plus fresh-agent smoke test. ## Quick Start Test whether my current Cloud Agent environment is compatible with environment builds and tell me what changes are needed before I enable builds.
