SuperAntigravity

You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.

Use when a task requires interacting with a web browser — testing UI flows, verifying web app behavior, clicking through screens, reading live web content, or automating browser workflows in Google Antigravity

Use when a task requires gathering information from external sources, researching unfamiliar technologies, validating technical approaches, or answering questions that need current web knowledge before implementation

Use when you have a spec or requirements for a multi-step task, before touching code

Use when creating new skills, editing existing skills, or verifying skills work before deployment

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Use when reviewing code for vulnerabilities, implementing authentication or authorization, handling user input, storing sensitive data, or before any feature that touches security boundaries goes to production

Use before implementing a feature or making significant changes to verify you have enough context and understanding to proceed — prevents wasted effort from proceeding with wrong assumptions

Use when designing new systems or significant features, evaluating architectural trade-offs, choosing between structural approaches, or when a task requires understanding system-wide design before writing code

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes

Use when adding new dependencies, deciding whether to update packages, running security audits on dependencies, evaluating library alternatives, or encountering outdated or vulnerable packages

Use when completing tasks, implementing major features, or before merging to verify work meets requirements

Use when implementing any feature or bugfix, before writing implementation code

Use when code is slow, resource-heavy, or needs optimization — before making any changes, after profiling reveals bottlenecks, or when designing performance-sensitive systems

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

Use when executing implementation plans with independent tasks in the current session

Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
