structural-search
Search code by AST structure using ast-grep. Find semantic patterns like function calls, imports, class definitions instead of text patterns. Triggers on: find all calls to X, search for pattern, refactor usages, find where function is used, structural search, ast-grep, sg.
perigon-agent
Pointers for Copilot/agents to apply Perigon conventions
treesitter-patterns
Universal patterns for tree-sitter code parsing. Covers AST visitors, query patterns, and language plugin development. Framework-agnostic.
installing-skill-tracker
Installs Claude Code hooks for automatic skill usage measurement. Use when setting up skill tracking infrastructure in a new project. NOT when hooks are already installed (run verify.py to check).
python-typing-patterns
Python type hints and type safety patterns. Triggers on: type hints, typing, TypeVar, Generic, Protocol, mypy, pyright, type annotation, overload, TypedDict.
semantic-code-hunter
Use when you need to find code by concept (not just text). Uses Serena MCP for semantic code search across the codebase with minimal token usage. Ideal for understanding architecture, finding authentication flows, or multi-file refactoring.
core-development
Work on the core package (types, validation, normalization, diff). Use when modifying DSL processing logic or data flow.
generating-rbs
Generates RBS type signatures from Ruby source files. Triggers when creating type definitions, adding types to Ruby code, or generating .rbs files for classes/modules without existing RBS signatures.
generating-sorbet
Generates Sorbet type signatures in separate RBI files from Ruby source files. Triggers when creating type definitions, adding types to Ruby code, or generating .rbi files for classes/modules without existing Sorbet signatures.
empathy-ledger-dev
Invoke this skill when: - Starting work on any Empathy Ledger feature - Need quick reference to project patterns
generating-sorbet-inline
Generates Sorbet inline type signatures using sig blocks directly in Ruby source files. Triggers when adding Sorbet types, annotating Ruby methods with sig syntax, or generating type signatures for Sorbet-typed projects.
clojure-write
Guide Clojure and ClojureScript development using REPL-driven workflow, coding conventions, and best practices. Use when writing, developing, or refactoring Clojure/ClojureScript code.
generating-rbs-inline
Generates RBS-inline type annotations directly in Ruby source files as comments. Triggers when adding inline type signatures, annotating Ruby methods with rbs-inline syntax, or generating type comments without existing inline annotations.
ancplua-docs
Search and answer questions about the ANcpLua ecosystem documentation. Use when users ask about ANcpLua.NET.Sdk features, ANcpLua.Analyzers rules, ANcpLua.Roslyn.Utilities APIs, or any configuration/usage questions about these packages.
reviewing-dotnet-code
Reviews and generates .NET/C# code following Microsoft conventions and modern patterns. Use when reviewing C# files, writing .NET code, refactoring, or when user mentions "C#", ".NET", "dotnet", "csharp", or asks about naming conventions in .NET projects.
css-development-refactor
This skill should be used when refactoring existing CSS from inline styles or utility classes to semantic patterns. Triggers on "refactor CSS", "extract styles", "consolidate CSS", "convert inline", "clean up styles", "migrate to semantic". Transforms to semantic classes with dark mode and tests.
figma-to-tailwind
Figma MCPで取得したデザイン変数をTailwind CSS標準クラスに変換する。Figma MCPのコード生成後やデザイン実装時に自動起動。
termdock-ast
Use the Termdock AST API to locate symbols, dependencies, callers/callees, or impact before exploring unknown code. Skip when the user gives an exact file path or only needs a literal string search.
tree-sitter-tdd
Use when adding a new F# language feature to the tree-sitter parser with TDD workflow
kata-map-codebase
Analyze an existing codebase with parallel mapper agents, creating codebase documentation, understanding brownfield projects, or mapping code structure. Triggers include "map codebase", "analyze codebase", "create project context", "document codebase", "understand code", and "codebase map".
reflect
Analyzes conversation transcripts to extract user corrections, patterns, and preferences, then proposes skill improvements. Use this skill when users provide corrections, express preferences about code style, or when patterns emerge from successful approaches. Can be triggered manually with /reflect or automatically at session end when enabled.
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
