Enforces language-specific coding rules, style guidelines, patterns, security, and testing standards by referencing a built-in guidelines bank.

Provides SwiftUI architecture guidance covering state management with @Observable, view composition, type-safe navigation, performance optimization, and modern iOS/macOS UI best practices.

Assesses a codebase by spawning a single mapper agent for a chosen focus area, producing targeted documents in .planning/codebase/.

Runs adversarial UI tests in a real browser, covering functional, accessibility, responsive, and UX checks, with diff-driven, exploratory, and parallel workflows.

Reference for building LLM-powered applications with the Claude API and Anthropic SDKs, covering model selection, parameters, streaming, tool use, and migration.

Guides efficient coding by enforcing a strict ladder of reuse, standard library, and minimal code before writing anything new.

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

Guides Git version control practices: branching strategies, commit conventions, merge vs rebase, conflict resolution, and pull request workflows for collaborative teams.

Write and run Perl tests using Test2::V0, Test::More, prove, mocking, and Devel::Cover coverage with a TDD workflow.

Guides adding new configuration settings to Wave Terminal's hierarchical config system, covering Go structs, JSON schema, defaults, docs, and frontend/backend usage.

Creates and displays context menus in Wave Terminal, covering menu item types, submenus, checkboxes, and event handling.

Resolves legacy references to 'perseus' by routing them to the current runtime capability, agent, or modern skill.

Provides 89 standard operating procedures for the Galyarder department, covering agent adapters, execution protocols, and multi-agent hygiene.

Resolves legacy references to `elite-developer` by routing to the appropriate modern runtime capability, agent, or plugin skill.

Resolves legacy references to the remotion-engineer skill by routing to the modern runtime capability.

Provides guidelines for building with Botpress's Agent Development Kit (ADK), covering project structure, primitives, CLI commands, and documentation lookups.

Builds and validates Joi schemas, including custom types, conditional validation with .when(), cross-field references, and custom error messages.

Implements features and writes code based on Plans.md tasks, with quality gates and routing to sub-skills for feature implementation and test writing.

Parses LibreOJ problem IDs or URLs, creates a folder, fetches the problem statement via Chrome DevTools MCP, saves it as Markdown, and writes a C++ solution file.

Provides RESTful API design patterns and best practices for creating endpoints, designing APIs, and implementing routes.

Guides users through the specification-driven development workflow, from requirements gathering through specification, test derivation, implementation, and validation.

Provides guidance and patterns for using a vector-powered CLI for semantic file search with Claude/Codex skills.

Coordinates five specialized coding agents (linter, perf, refactor, security, test) to enforce quality gates across the development lifecycle, from lint enforcement through performance profiling, refactoring, security auditing, and test coverage.

Generates YouTube videos from prompts, creates vertical Shorts from text, and converts long videos into Shorts using free tools like ffmpeg, edge-tts, and Pexels.

Implements the MVVM pattern in Flutter with Provider and ChangeNotifier, structuring projects into models, views, and viewmodels for testable, maintainable code.

Configures and runs static analysis and linting tools across multiple languages, integrating with CI/CD and security platforms.
