Use when Elixir pattern matching including function clauses, case statements, with statements, and destructuring. Use for elegant control flow.
Guidance for generating legal chess moves using only regex pattern matching and substitution. This skill applies when implementing chess move generators constrained to regex-only solutions, FEN notation parsing/manipulation, or similar pattern-matching-based board game logic. Use this skill for tasks requiring regex-based state transformations on structured string representations.
Create a Positioning & Messaging Pack (positioning statement, messaging hierarchy, value proposition, tagline/headlines, copy set, validation plan). Use for positioning, messaging, value prop, tagline, homepage hero, one-liner, elevator pitch, and press pattern-matching.
Evaluates and optimizes agent skills using a DSPy-powered GEPA (Generate/Evaluate/Propose/Apply) loop. Loads scenario YAML files as DSPy datasets, scores outputs with pattern-matching metrics, and optimizes prompts via BootstrapFewShot or MIPROv2 teleprompters. Also generates new scenario YAML files from skill descriptions.
Guide for writing ast-grep rules to perform structural code search and analysis. Use when users need to search codebases using Abstract Syntax Tree (AST) patterns, find specific code structures, or perform complex code queries that go beyond simple text search. This skill should be used when users ask to search for code patterns, find specific language constructs, or locate code with particular structural characteristics.
Reviews Elixir code for idiomatic patterns, OTP basics, and documentation. Use when reviewing .ex/.exs files, checking pattern matching, GenServer usage, or module documentation.
Write AST-based code search and rewrite rules using ast-grep YAML. Create linting rules, code modernizations, and API migrations with auto-fix. Use when the user mentions ast-grep, tree-sitter patterns, code search rules, lint rules with YAML, AST matching, or code refactoring patterns.
General best practices for Dart development. Covers code style, effective Dart, and language features.
Guidelines for using modern Dart features (v3.0 - v3.10) such as Records, Pattern Matching, Switch Expressions, Extension Types, Class Modifiers, Wildcards, Null-Aware Elements, and Dot Shorthands.
C# 12 language features including records, pattern matching, nullable reference types, LINQ, async/await, and modern language patterns. USE WHEN: user mentions "C#", "C# records", "pattern matching", "LINQ", "async/await", "nullable reference types", "C# generics", "C# language features" DO NOT USE FOR: TypeScript - use `typescript`, Java - use Java skills, F# or VB.NET specific features
Master core and advanced language syntax for expressive and type-safe code.
Use this skill when writing regular expressions, debugging pattern matching, optimizing regex performance, or implementing text validation. Triggers on regex, regular expressions, pattern matching, lookahead, lookbehind, named groups, capture groups, backreferences, and any task requiring text pattern matching.
