Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links, automate any browser task. Use for cross-browser testing, visual regression, API testing, component testing in TypeScript/JavaScript and Python projects.

Browser automation, web scraping, and visual testing with Playwright on Display :1. Use for navigating web pages, clicking elements, filling forms, taking screenshots, executing JavaScript, and visual verification of web applications. Visual access available via VNC on port 5901.

Expert guidance for Google Ads Script development including AdsApp API, campaign management, ad groups, keywords, bidding strategies, performance reporting, budget management, automated rules, and optimization patterns. Use when automating Google Ads campaigns, managing keywords and bids, creating performance reports, implementing automated rules, optimizing ad spend, working with campaign budgets, monitoring quality scores, tracking conversions, pausing low-performing keywords, adjusting bids based on ROAS, or building Google Ads automation scripts. Covers campaign operations, keyword targeting, bid optimization, conversion tracking, error handling, and JavaScript-based automation in Google Ads editor.

Named Tmux Manager - orchestrate multiple AI coding agents (Claude Code, Codex, Gemini) in tiled tmux panes with visual dashboards, command palette, context rotation, Agent Mail integration, and robot mode for automation.

Deterministically find license information for Python packages by checking PyPI metadata first, then falling back to Git repository LICENSE files using shallow cloning.

Rule 07: Testing. Use when writing tests, reviewing test coverage, or setting up testing.

Herramientas de Calidad - ESLint, TypeScript, Prettier. Use when setting up quality tools or CI.

Run code snippets in 30+ programming languages including JavaScript, Python, TypeScript, Java, C, C++, Go, Rust, Ruby, PHP, and more. Use when the user wants to execute code, test algorithms, verify output, run scripts, or check code behavior. Supports both interpreted and compiled languages.

Don't Repeat Yourself (DRY) and Never Reinvent the Wheel (NRtW) - core b00tprinciples. Use existing libraries, leverage Rust via PyO3 instead of duplicatinglogic in Python, and contribute to upstream projects rather than fork privately.

Regra 07: Testes. Use when writing tests, reviewing test coverage, or setting up testing.

Architecture Python - Clean Architecture & Hexagonale. Use when designing architecture or reviewing code structure.

Python Architecture - Clean Architecture & Hexagonal. Use when designing architecture or reviewing code structure.

Analyzes PDFs, images, screenshots, diagrams, and documents using Gemini multimodal. Extracts text, tables, forms; interprets visuals, architecture diagrams, flowcharts, ERDs. Use when user mentions PDFs, images, screenshots, document extraction, OCR, visual analysis, diagram interpretation, or form processing. Do not use for web searching or shell commands.

Master context engineering for AI features - the skill that separates AI products that work from ones that hallucinate. Use when speccing new AI features, diagnosing underperforming AI features, or doing quality checks before shipping. Helps PMs define what context AI needs, where to get it, and what to do when it fails. Based on the 4D Context Canvas framework.

Structured implementer-verifier-reviewer pipeline for high-quality code. Artifact-based handoffs between roles. Use when needing rigorous review process, handoff between roles, or review pipeline for critical changes.

Python-Architektur - Clean Architecture & Hexagonal. Use when designing architecture or reviewing code structure.

Regel 07: Testing. Use when writing tests, reviewing test coverage, or setting up testing.

Analyzes CSV files and generates comprehensive summary statistics and visualizations using Python and pandas - automatically and immediately without asking what the user wants.

Idiomatic Python 3.14+ development. Use when writing Python code, CLI tools, scripts, or services. Emphasizes stdlib, type hints, uv/ruff toolchain, and minimal dependencies.
