1. Software Development

Provides a framework for building Chrome extensions with TypeScript and modern frontend frameworks like React, Vue, and Svelte.

Provides tools for developing, testing, and deploying Ethereum smart contracts using Foundry's Forge, Cast, and Anvil.

Enables server state management in React apps with TanStack Query v5 for data fetching, caching, and mutations.

Provides command-line access to GitHub for remote repository analysis, file fetching, codebase comparison, and discovering trending projects without cloning.

Expert guidance for developing Talon voice control applications, including command creation, action definition, and debugging in .talon configuration files.

Validates code review feedback against implementation plans to prevent scope creep and ensure development alignment.

Provides a structured workflow for conducting thorough code reviews with standardized feedback templates and best practices.

Provides a safe, incremental refactoring workflow for replacing legacy types with type-safe implementations using integration tests and file-by-file migration.

Automates code review dispatch to verify implementation against requirements before merging or feature completion.

Enforces Test-Driven Development (TDD) via algorithmic decision tree using boolean conditions to guide development steps.

Provides a four-phase debugging framework (root cause investigation, pattern analysis, hypothesis testing, implementation) to ensure thorough understanding before proposing fixes.

Creates isolated Git worktrees for feature development with smart directory selection and safety verification to prevent workspace conflicts.

Automates software implementation by dispatching subagents for independent tasks with built-in code review, ensuring quality and fast iteration.

A development practice where tests are written before code to ensure they verify behavior by requiring a failing test first.

Automates RED-GREEN-REFACTOR testing for skill development, ensuring robustness by iteratively addressing failures before deployment.

Guides developers through final branch integration steps, offering structured options for merging, pull requests, or cleanup after successful implementation and testing.

Enforces structured Git commits with pre-commit checks, atomic changes, and conventional message standards for maintainable code history.

Guides developers through contributing skills to upstream repositories using Git: branching, committing, pushing, and pull request creation.

Creates detailed implementation plans with exact file paths, code examples, and verification steps for engineers with minimal domain knowledge.

Generates comprehensive, idiomatic tests adhering to best practices for unit, integration, and fixture tests.

Test skill verifying progressive file loading behavior with multiple resources in application development contexts.

Automates delegation of complex backend logic and algorithms to OpenAI Codex CLI for execution, enabling AI-to-AI collaboration in code development.

Creates Datasette plugins via Python using pluggy, implementing hooks, custom SQL, and UI extensions for data exploration tools.

Generates optimized code for custom skills by integrating MCP servers into user-defined workflows, adhering to Anthropic's best practices.
