Development

Web search and content extraction via Brave Search API.

Send WhatsApp messages to other people or search/sync WhatsApp history via the wacli CLI (not for normal user chats).

Send system notifications to specific Clawdis nodes (macOS computers) via the Gateway and CLI. Use when you need to alert a person or confirm a remote action on a particular machine, or when an agent must push a notification to another computer.

Batch-generate images via OpenAI Images API. Random prompt sampler + `index.html` gallery.

Use when implementing any feature or bugfix, before writing implementation code

Fetch content from Reddit using Gemini CLI when WebFetch is blocked. Use when accessing Reddit URLs, researching topics on Reddit, or when Reddit returns 403/blocked errors. (user)

Comprehensive testing and validation strategies for spec-driven development. Learn phase-specific validation techniques, quality gates, and testing approaches to ensure high-quality implementation.

Systematic three-phase approach to feature development using Requirements, Design, and Tasks phases. Transforms vague feature ideas into well-defined, implementable solutions that reduce ambiguity, improve quality, and enable effective AI collaboration.

Transform vague feature ideas into clear, testable requirements using EARS format. Capture user stories, define acceptance criteria, identify edge cases, and validate completeness before moving to design.

Transform approved requirements into comprehensive technical designs. Define system architecture, component interactions, data models, and interfaces to create a blueprint for implementation.

Async via cask, end turn immediately; use only when user explicitly delegates to Codex (ask/@codex/let codex/review); NOT for questions about Codex itself.

Allows to interact with web pages by performing actions such as clicking buttons, filling out forms, and navigating links. It works by remote controlling Google Chrome or Chromium browsers using the Chrome DevTools Protocol (CDP). When Claude needs to browse the web, it can use this skill to do so.

Writing effective code documentation - API docs, README files, inline comments, and technical guides. Use for documenting codebases, APIs, or writing developer guides.

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems.

Code refactoring patterns and techniques for improving code quality without changing behavior. Use for cleaning up legacy code, reducing complexity, or improving maintainability.

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

Write tailored cover letters and job applications using your CV and preferred style
