Your agent can do more. Find the skill that makes it happen.
Find your next superpower If you are an agent, refer to our llms.txt for full access.Decompile, analyze, and reverse engineer Android applications (APKs). Utilize tools like JADX, Apktool, and dex2jar to extract source code (Java/Kotlin), analyze manifest configurations (Intents, Activities), and identify hardcoded secrets or insecure API endpoints.
Validates Android UI behavior before release. Focuses on empty, loading, error, offline, and edge-case states across user flows.
Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use …
Review a feature and enhance it with purposeful animations, micro-interactions, and motion effects that improve usability and delight.
Build animations in React Native and Expo, making the decisions in the order that determines whether they feel right — should it animate, which thread it runs on, which properties, spring or timing, how the gesture hands off, how it degrades. Writes the implementation with Reanimated, Gesture Handler, Expo Router and expo-haptics. Use when animating anything in an Expo app, adding gestures, sheets…

Carries out a supplied specification and maintains an apply-notes HTML file. Records decisions and tradeoffs that fall outside the specification.
Design stable APIs and module boundaries — contract-first types, consistent errors, boundary validation, additive changes. Load when designing REST or GraphQL endpoints, public module interfaces, component props, or FE/BE contracts. Also triggers on "API design", "interface design", "design the API", "module boundary", "API contract", "define the interface". Complements feature-spec (product layer…
Test APIs for authentication and authorization bypass vulnerabilities including JWT manipulation, OAuth2 flaws, API key leakage, broken authentication, and token forgery. Use this skill when assessing REST/GraphQL APIs for access control weaknesses, session management flaws, or credential handling issues. Covers JWT algorithm confusion, OAuth redirect manipulation, and rate limit bypass.
Governs shared API types and payloads across server, web, and mini-program clients. Covers Drizzle-derived Zod schemas, shared DTO modules, cross-platform type consumption, validation, and lightweight /api/v1/* versioning.
Deprecate APIs, features, or systems safely — announce, migrate consumers, sunset on a timeline, and document alternatives. Load when removing an old API, migrating users between implementations, sunsetting a feature, or the user asks about deprecation policy, migration guides, or breaking changes. Not for deleting dead code with zero consumers (use code-simplification). Distinct from meta deprec…
Проектирование HTTP API — REST-конвенции (ресурсы, методы, статус-коды), пагинация (cursor vs offset), версионирование, идемпотентность (Idempotency-Key), формат ошибок RFC 7807 (problem+json), безопасность и rate limiting. Use при проектировании, ревью или версионировании API и эндпоинтов, выборе кодов ошибок, пагинации, лимитов или формата ответа.
