Tui Runner

Use when the user invokes /tui-runner to install, configure, or manage the terminal-mcp MCP server for headless terminal emulation in Claude Code.

Nextjs Best Practices

Next.js App Router principles. Server Components, data fetching, routing patterns.

Next.js 16 — Metadata Functions

Next.js 16 App Router metadata functions reference. Use this skill when working with generateMetadata, generateViewport, generateStaticParams, generateImageMetadata, generateSitemaps, or ImageResponse. Covers all Metadata object fields (title, description, openGraph, twitter, icons, robots, alternates, viewport, themeColor, formatDetection), viewport configuration, static generation, and dynamic OG images. Trigger on any question about SEO, Open Graph, Twitter cards, page metadata, static site generation, sitemaps, or OG image generation in Next.js 16.

Next.js 16 — Directives

Next.js 16 App Router directives reference. Use this skill when working with 'use cache', 'use cache: remote', 'use cache: private', 'use client', or 'use server'. Covers all caching levels (file/component/function), cacheLife profiles, cache keys, dynamic content inside cache, Server Actions, and client-boundary rules. Trigger on any question about caching directives, server/client boundaries, or when implementing Server Actions in Next.js 16.

Frontend

Vercel Composition Patterns

React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.

Education

Type Fest

TypeScript utility types library with 180+ compile-time transformations for strict type operations, deep object manipulation, case conversions, and JSON-safe typing. Use when building type-safe APIs, config systems, state management, transforming external data schemas or when you are creating a new type.

Zod

Zod schema validation best practices for type safety, parsing, and error handling. This skill should be used when defining z.object schemas, using z.string validations, safeParse, or z.infer. This skill does NOT cover React Hook Form integration patterns (use react-hook-form skill) or OpenAPI client generation (use orval skill).

Media

Background Batch

Remove backgrounds from multiple images in batch. Processes a folder or selection of assets and saves results in a dedicated folder.

Go Coding Style

Use when writing, reviewing, or modifying Go code (*.go, go.mod, go.sum files) or reviewing diffs/PRs containing Go changes — ensures code quality and adherence to the established Go conventions for naming, error handling, concurrency, types, logging, and code organization

Mobile

Android Device

Use when working with Android phones or tablets — fastboot, adb, flashing, kernel updates, device debugging.

CI/CD

Agent Teams Execution

Use when facing any non-trivial software building or debugging task that spans multiple independent workstreams

Harness Tuning

Use when writing, reviewing, shortening, tightening, deduplicating, or compressing any skill file, system prompt, subagent prompt, or CLAUDE.md — including when asked to "fix" or "improve" a prompt file.

Explore Critique Implement

Use when solving any non-trivial problem where the solution space is uncertain — research options via a separate agent, adversarially critique them via a different agent, then loop (implement → critique) until the critic finds nothing. Skip only for single-line or trivial changes.

Python Coding Style

Use when writing, reviewing, or modifying Python code (*.py, pyproject.toml, setup.cfg files) or reviewing diffs/PRs containing Python changes — ensures code quality and adherence to established Python conventions for naming, error handling, concurrency, typing, logging, and code organization

Proof Driven Development

Use when implementing any software with logic — proves correctness in Lean 4 first, then translates to the target language with differential testing. Skip only for pure configuration or glue code with no logic.

Architecture Patterns

Ffstream

Operational, architectural, and environmental rules for the ffstream live streaming project.

Architecture Patterns

Avpipeline

Architectural patterns and rules for the avpipeline project (portable libav wrapper).

Architecture Patterns
