python-engineer
Writes, reviews, and refactors Python code following modern best practices. Specialises in Python 3.12+, uv for project management, type hints, polars over pandas, pydantic for validation, and pytest for testing. Use when working with Python code.
dspy-signature-designer
Design type-safe DSPy signatures with InputField, OutputField, and advanced type hints
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).
parsing-and-mutating-strings
Utilities in this library which provide effective ways to parse or mutate text at both runtime and design-time while ensuring that the resulting type is as narrow as possible.
hierarchical-agents
Generate hierarchical AGENTS.md structure for codebases to optimize AI agent token usage. Use when creating AGENTS.md files, documenting codebase structure, setting up agent guidance, organizing project documentation for AI tools, implementing JIT indexing, or working with monorepos that need lightweight root guidance with detailed sub-folder documentation. Covers repository analysis, root AGENTS.md generation, sub-folder AGENTS.md creation, and token-efficient documentation patterns.
command-patterns
Advanced patterns for generating high-quality Claude Code commands. Used by /new-command.
flow-next-opencode-impl-review
John Carmack-level implementation review via RepoPrompt or OpenCode. Use when reviewing code changes, PRs, or implementations. Triggers on /flow-next:impl-review.
preflight-checks
Comprehensive code quality verification system for running type checking, linting, and tests. Use when validating code quality, preparing commits, running CI checks locally, or when the user mentions preflight, verify, lint, typecheck, or test commands.
repository-analyzer
Analyzes codebases to generate comprehensive documentation including structure, languages, frameworks, dependencies, design patterns, and technical debt. Use when user says "analyze repository", "understand codebase", "document project", or when exploring unfamiliar code.
nvim-context
Get the current Neovim context as JSON (cursor position, current file, visual selection and diagnostics) to help answer questions about code at the current cursor position, visual selections and diagnostics. Use when users ask about "this line", "current file", "selection" or need context about their Neovim editor state.
complexity-management
Maintain and improve code quality using PHPInsights without decreasing quality thresholds. Use when PHPInsights fails, cyclomatic complexity is too high, code quality drops, or when refactoring for better maintainability. Always maintains 94% complexity and 100% quality/architecture/style scores.
examplescode-reviewer
AI-powered code review tool that analyzes code for bugs, style issues, and improvements
parser-developer
Guides AILANG parser development with conventions and patterns. Use when user wants to modify parser, understand parser architecture, or debug parser issues. Saves 30% of development time by preventing token position bugs.
language-expert
Use for language design questions including syntax decisions, semantics, grammar authoring, and comparing DomainLang with other DSLs. Activate when designing new language features, evaluating syntax alternatives, or discussing DDD pattern representation.
grey-haven-code-style
Apply Grey Haven Studio's TypeScript/React and Python/FastAPI coding standards from production templates. Use when writing code, reviewing PRs, fixing linting errors, formatting files, or when the user mentions 'code standards', 'Grey Haven style', 'linting', 'Prettier', 'ESLint', 'Ruff', 'formatting rules', or 'coding conventions'. Includes exact Prettier/ESLint/Ruff configs, naming conventions, project structure, and multi-tenant database patterns.
grey-haven-plugin-audit
Comprehensive Claude Code plugin auditing skill for validating structure, detecting deprecated patterns, and recommending best practices based on the latest changelog. Use when auditing plugins, checking for deprecations, validating plugin structure, preparing plugins for release, or ensuring compatibility with recent Claude Code versions. Triggers: 'audit plugin', 'check plugin health', 'validate skill', 'plugin deprecation', 'changelog compatibility', 'plugin best practices'.
codebase-organizer
Monitor and refactor large files into smaller, AI-friendly modules. Use when user asks to check file sizes, split large files, or organize the codebase. Ensures tests pass before and after refactoring.
typescript-quality-checker
Validate TypeScript/JavaScript code quality with ESLint, Prettier, type checking, and security analysis. Use for TypeScript/JS codebases to ensure code quality and standards.
code-review
Reviews code changes for bugs, security issues, and adherence to codebase patterns. This skill should be used when reviewing diffs, commits, branches, or pull requests. It focuses on finding real bugs (not style nitpicks), verifying code fits existing patterns, and providing actionable feedback with clear severity levels.
python-quality-checker
Validate Python code quality with formatting, type checking, linting, and security analysis. Use for Python codebases to ensure PEP 8 compliance, type safety, and code quality.
script-kit-icons
Unified icon system for Script Kit GPUI. Use when working with icons in the UI - rendering Lucide icons, embedded SVGs, SF Symbols (macOS), app bundle icons, or custom file/URL icons. Covers IconRef parsing, IconStyle configuration, color tokens, and the IconView rendering API.
