testing-anti-patterns
This skill identifies and prevents common testing mistakes like testing mock behavior instead of real functionality, adding test-only methods to production code, and creating incomplete mock data. It provides concrete examples, detection rules, and fixes for each anti-pattern. The guidance helps developers write tests that verify actual behavior rather than mock implementation details.
backend-python-standards
Comprehensive Python backend development skill that enforces modern tooling standards with clear, actionable guidance for package management, testing, code quality, and documentation practices.
write-concept
Write or review JavaScript concept documentation pages for the 33 JavaScript Concepts project, following strict structure and quality guidelines
pymatgen

scientific-writing
This skill provides structured LaTeX templates and workflows for writing scientific manuscripts. It enforces IMRAD structure, citation formatting, and mandatory visual elements. The two-stage process (outline then prose) and detailed examples help researchers produce publication-ready documents with proper statistical reporting.
xlsx
This skill provides tools for creating, editing, and analyzing Excel files with a strong emphasis on formula usage over hardcoding. It includes specific workflows for financial modeling with color coding standards, number formatting rules, and mandatory formula recalculation via LibreOffice. The documentation clearly distinguishes between pandas for data analysis and openpyxl for Excel-specific features.
xlsx
This skill enables Claude to create, edit, and analyze Excel files with proper formulas and formatting. It provides clear workflows for financial modeling with color coding standards, prevents hardcoding by enforcing formula usage, and includes a recalculation script to verify formula correctness. The documentation covers common pitfalls and verification steps.
observability-design
Comprehensive observability reference guide covering essential patterns, SLI/SLO design, alerting strategies, and dashboard principles with practical examples and actionable advice.
brainstorming
A structured conversational assistant that guides developers from initial ideas to concrete software designs. It asks focused questions, proposes multiple approaches, and documents validated plans before implementation begins.
agent-browser
Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
advanced-evaluation
This skill should be used when the user asks to "implement LLM-as-judge", "compare model outputs", "create evaluation rubrics", "mitigate evaluation bias", or mentions direct scoring, pairwise comparison, position bias, evaluation pipelines, or automated quality assessment.
buck2-rule-basics
An interactive tutorial skill that teaches Buck2 rule writing through hands-on practice. It guides users step-by-step from creating a simple text processing rule to understanding configurations, dependencies, and advanced patterns. Includes reference materials for deeper questions and emphasizes adaptive teaching.
astropy
This skill provides access to the Astropy Python library for astronomical data processing. It handles coordinate transformations, FITS file operations, cosmological calculations, unit conversions, and table manipulations. The documentation includes clear examples for common astronomy workflows like cross-matching catalogs and calculating distances.
pr-workflow
Automates GitHub pull request creation with specific guidelines for commit analysis, documentation updates, and PR formatting. Integrates with git diff, GitHub CLI, and external tools for verification. Provides concrete examples of proper PR formatting with source links and code comparisons.
ffmpeg-core
A comprehensive and well-structured FFmpeg reference guide covering essential video/audio operations with practical examples, codec recommendations, and performance optimization tips.
canvas-design
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
multi-agent-patterns
This skill should be used when the user asks to "design multi-agent system", "implement supervisor pattern", "create swarm architecture", "coordinate multiple agents", or mentions multi-agent patterns, context isolation, agent handoffs, sub-agents, or parallel agent execution.
data-viz-plots
This skill provides ready-to-use Python code templates for creating publication-quality scientific plots using matplotlib and seaborn. It covers common visualization types like scatter plots, heatmaps, violin plots, and volcano plots with specific styling recommendations for academic papers.
