Guides creation of effective Agent Skills with proper structure and validation. Use when users want to create a new skill, update an existing skill, or need guidance on skill design patterns, SKILL.md format, or verify.py implementation. NOT when just using existing skills (use those skills directly).

Advanced TypeScript patterns and best practices for 2025. Use when working with TypeScript projects requiring type system mastery (generics, conditional types, mapped types), tsconfig optimization, runtime validation integration (Zod, TypeBox, Valibot), or type-safe API patterns. Essential for Next.js, Node.js, and full-stack TypeScript development.

Guidance for developing OSC RIC xApps (RC/KPM/E2 subscription patterns), safe integration steps, and common pitfalls (polling vs periodic reporting).

Use when PRD is prose-heavy, ambiguous, has scattered file paths, missing API contracts, or says "similar to X" without explanation. Transforms rough requirements into implementation-ready specs. Auto-detects tech stack, validates file paths (EXISTS/CREATE/VERIFY markers), handles greenfield and multi-stack projects. Do NOT use for simple bug fixes, typos, or already-structured Jira tickets with clear file paths and acceptance criteria.

Create distinctive, production-grade frontend interfaces with high design quality. Provides analysis tools for auditing existing designs and generation tools for creating color palettes, typography systems, design tokens, and component templates. Supports React, Vue, Svelte, and vanilla HTML/CSS. Use when building web components, pages, or applications. Keywords: design, UI, frontend, CSS, components, palette, typography, tokens, accessibility.

Interpretive guidance for Claude Code output styles - when they add value, when they don't, and how they relate to agents. Use when considering output styles or wondering if your workflow would benefit from them.

Resource safety with acquireRelease, Effect.scoped, and finalizers. Use when opening files, sockets, servers, or external handles.

Create and manage database migrations for schema changes, ensuring zero-downtime deployments and data integrity. Use this skill when creating migration files, modifying database schemas, adding or altering tables/columns/indexes, or working with migration tools like Alembic, Flyway, Liquibase, or framework-specific migration systems (Django migrations, Rails migrations, Prisma migrations). Apply this skill when implementing reversible migrations with up/down methods, handling data migrations separately from schema changes, creating indexes on large tables, or planning backwards-compatible schema changes for high-availability systems. This skill ensures migrations are version-controlled, focused, safe to rollback, and compatible with CI/CD pipelines and zero-downtime deployment strategies.
