The version-checker skill analyzes Python dependencies for version compatibility, breaking changes, and security vulnerabilities. It validates version specifiers, checks Python version compatibility, and recommends upgrade paths. Use this skill when validating dependency declarations or planning upgrades to ensure compatibility and security.

The validation skill performs automated code quality checks, test coverage analysis, and security scanning to verify features meet all standards before completion. It serves as a final quality gate after implementation, using tools like Black, mypy, and flake8 to ensure requirements are fulfilled before marking work done or creating pull requests.

The validation-coordinator skill automatically manages sequential validation workflows by coordinating 5-6 specialists. It handles dependency tracking, monitors validation status, and ensures quality gates are met before deployment. Use this skill when you need to orchestrate multi-step validation processes involving test writing, execution, and security scans.

This skill generates comprehensive unit tests with proper structure, mocking, and coverage across multiple programming languages. It provides systematic guidance for creating new tests, improving existing coverage, and following TDD methodology. Use it when you need actionable best practices for test organization, fixtures, and the Arrange-Act-Assert pattern.

This skill validates TypeScript/JavaScript code quality by running ESLint, Prettier, type checking, and security analysis. Use it for pre-commit validation, CI/CD quality gates, or code review preparation to ensure your code meets standards and best practices. It's ideal for TypeScript/JS codebases needing automated quality checks.

The test-generator skill creates comprehensive test scaffolding for modules, generating proper test structure, fixtures, and mock configurations. It helps developers quickly set up unit and integration tests following pytest or Jest best practices. Use it when starting tests for new modules or adding tests to existing code via the `/generate-tests` command.

The recursive-communicator skill automatically manages agent-to-agent communication for validation failures and recursive fix cycles. It handles failure notifications, fix requests, and re-validation triggers between validation specialists and the main agent, ensuring issues are resolved systematically. The skill also tracks iteration counts to prevent deadlocks in these recursive loops.

The prp-generator skill auto-activates to create structured Product Requirements Prompt (PRP) documents from synthesized design outputs. It provides comprehensive templates containing implementation plans, testing strategies, dependencies, and success criteria. Developers use it to transform architectural designs into actionable guidance for the implementation phase.

The pr-creator skill helps developers generate high-quality pull requests by providing systematic guidance for creating comprehensive PR descriptions, test plans, and proper git workflows. It should be used when finalizing features to ensure all changes are committed, tests are passing, and project standards are met. This skill utilizes Read, Bash, and Grep tools to verify readiness and follow best practices before code review.

This skill generates structured project assessment markdown documents from JSON input data. It automatically creates WHY/WHO/WHAT sections and includes a GO/NO-GO decision matrix for project evaluation. Developers should use it when they need to quickly generate planning documentation from structured project data.

This is a basic permission testing skill template for developers to use with Claude Code. It serves as a starting point for creating custom skills and includes sections for instructions, examples, and troubleshooting. Developers should customize this template by replacing the placeholder content with their specific use case details.

This skill automatically generates Jest-based unit tests for JavaScript and TypeScript code, creating test files that follow Jest conventions. It produces comprehensive test suites with proper mocking, describe blocks, and coverage for modules and React components. Use it to quickly add missing test coverage or generate Jest-specific patterns like spies and snapshots.

This Claude Skill implements features by generating code, tests, and documentation, following approved designs. It is used after the design phase to build features while adhering to TDD and project coding standards. The skill utilizes tools like Read, Write, Edit, and Bash to systematically develop high-quality software.

This is a template skill for testing file permissions that developers can customize for their specific use cases. It provides a basic structure with sections for instructions, usage examples, and troubleshooting guidance. The skill is designed to be invoked by Claude Code when file permission testing tasks match its description.

This skill enables developers to manage GitHub operations through Claude, including creating milestones with titles, descriptions, and due dates. It handles authentication checks, repository information retrieval, and milestone creation via GitHub CLI commands. Use this for automating common GitHub repository management tasks directly from your development workflow.

The xlsx skill enables Claude to comprehensively work with spreadsheet files for creation, editing, and analysis. It supports formulas, formatting, data analysis, and visualization while preserving existing structures when modifying files. Use this skill when you need to create, read, modify, or analyze spreadsheet data with guaranteed formula integrity.

This skill analyzes urban development projects through planning frameworks like zoning, land use, and transit-oriented development. It provides insights on spatial organization, infrastructure, sustainability, and livability. Use it for zoning decisions, transportation planning, and sustainability initiatives to evaluate density, accessibility, and environmental impact.

This skill analyzes events through core sociological frameworks including functionalist, conflict, and symbolic interactionist perspectives. It provides insights on social patterns, group dynamics, inequality, and social change by evaluating social structures, power relations, and cultural norms. Use it when examining social movements, institutional behavior, cultural trends, or collective action.

This Claude Skill analyzes technical systems and problems using engineering principles like first principles and systems thinking. It provides insights on feasibility, performance, reliability, and trade-offs during system design, optimization, or failure analysis. Use it to evaluate requirements, constraints, and technical decisions for robust and scalable solutions.

The economist-analyst skill analyzes events through an economic lens, applying concepts like supply/demand, incentive structures, and multiple schools of economic thought. It provides insights on market impacts, resource allocation, and policy implications for scenarios like economic events, policy changes, and market shifts. Use this skill to evaluate incentives, efficiency, opportunity costs, and systemic risks.

This skill enables developers to create, edit, and analyze Word documents programmatically. It supports tracked changes via a recommended redlining workflow, which is essential for legal, academic, and business documents. The skill also provides methods for text extraction, raw XML access, and basic OOXML editing for different document manipulation tasks.

This skill handles Firebase/Firestore operations including CRUD, queries, and batch processing for standard applications. It also supports advanced A2A agent communication patterns and integrates with MCP servers and Cloud Run services. Use it when working with Firestore operations, agent-to-agent messaging, or Cloud Run integration.
