Claude Skills

Test writing and fixing methodology. Covers TDD, investigating failures, and delegating fixes to agents. Use when writing tests or diagnosing test failures.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Create comprehensive MATLAB unit tests using the MATLAB Testing Framework. Use when generating test files, test cases, unit tests, test suites, or when the user requests testing for MATLAB code, functions, or classes.

Build interactive web applications using HTML/JavaScript interfaces with MATLAB computational backends via the uihtml component. Use when creating HTML-based MATLAB apps, JavaScript MATLAB interfaces, web UIs with MATLAB, interactive MATLAB GUIs, or when user mentions uihtml, HTML, JavaScript, web apps, or web interfaces.

Provides comprehensive Saleor e-commerce domain knowledge including entity types, relationships, identifier rules, and GraphQL patterns. This skill should be invoked when the user needs to understand Saleor concepts, entity relationships, the difference between product-level and variant-level attributes, or how channels, warehouses, and shipping zones interact. Essential for understanding how Configurator maps to Saleor's data model.

Optimize MATLAB code for better performance through vectorization, memory management, and profiling. Use when user requests optimization, mentions slow code, performance issues, speed improvements, or asks to make code faster or more efficient.

Provides pre-built Saleor configuration templates for common e-commerce store types including fashion retail, electronics, and subscription services. This skill should be invoked when the user wants to start with a template, needs a complete store setup example, or is looking for best-practice configurations. Templates include channels, product types, categories, and attributes tailored to each business model.

Guide for analyzing and improving application performance including identifying bottlenecks, implementing caching, and optimizing queries. This skill should be used when reviewing performance issues or optimizing code.

Provides comprehensive guidance for transforming external product data into Saleor config.yml format. This skill should be invoked when the user needs to import products from CSV files, Excel spreadsheets, Shopify exports, or any external data source. Covers file format detection, column mapping strategies, variant grouping, and output validation.

Use when creating implementation plans, phase planning documents, breaking features into phases, or when /workflow-plan-phases command is invoked. Provides methodology for context-efficient phase sizing and dependency analysis.

Guide for conducting comprehensive web dependency security scans to identify outdated libraries, CVEs, and security misconfigurations. Use when analyzing deployed websites for dependency vulnerabilities.

Use when implementing phases from a plan document, executing phased implementations, orchestrating sub-agents for phase work, or when /workflow-implement-phases command is invoked. Provides dependency analysis and parallel/sequential execution strategies.

Provides comprehensive guidance for Saleor Configurator CLI commands and usage patterns. This skill should be invoked when the user asks about deploying configurations, introspecting stores, running diffs, or executing any CLI operations against a Saleor instance. Covers deploy, introspect, diff, and start commands with all flags and environment variables.

Guide for conducting comprehensive security audits of code to identify vulnerabilities. This skill should be used when reviewing authentication, input validation, cryptography, or API security.

Comprehensive code quality verification system for running type checking, linting, and tests. Use when validating code quality, preparing commits, running CI checks locally, or when the user mentions preflight, verify, lint, typecheck, or test commands.

Transform vague or ambiguous requirements into precise, actionable specifications through structured questioning. Use when user says "clarify", "refine requirements", or when requirements are unclear, incomplete, or open to multiple interpretations. Always use before implementing any ambiguous feature request.

Create MATLAB plain text Live Scripts (.m files) following specific formatting rules. Use when generating MATLAB scripts, educational MATLAB content, Live Scripts, or when the user requests .m files with rich text formatting.

Designs and validates digital filters in MATLAB. Use when cleaning up noisy signals, removing interference, filtering signals, designing FIR/IIR filters (lowpass/highpass/bandpass/bandstop/notch), or comparing filters in Filter Analyzer.
