Build checkout and payment experiences using Primer's web components. Use this skill when implementing payment flows, checkout pages, card forms, or integrating Primer SDK into React, Next.js, or vanilla JavaScript applications. Covers component usage, React integration patterns, stable object references, event handling, SSR support, and CSS theming.

This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol, (2) Systematically evaluating each dimension with specific criteria, (3) Providing actionable findings with file:line references. Triggers when users request: code analysis, design review, refactoring opportunities, code quality assessment, architecture evaluation.

Method implementation finder and analyzer for Pharo Smalltalk. Provides expertise in discovering implementors across class hierarchies (search_implementors), analyzing implementation patterns, learning coding idioms from existing implementations, assessing refactoring impact (counting implementors and references), finding duplicate code for consolidation, understanding abstract method implementations (subclassResponsibility), and tracing method overrides through inheritance chains. Use when analyzing method implementations across classes, learning implementation idioms, assessing refactoring risk before changes, finding duplicate implementations for consolidation, understanding how abstract methods are implemented in concrete classes, or tracing which classes override specific methods.

Automated generation of journal article drafts from HTA systematic review reports. Use when users want to (1) convert an HTA/systematic review report into a journal submission, (2) extract clinical and cost-effectiveness data from HTA reports, (3) generate first drafts following specific journal guidelines, or (4) process NICE, ICER, CADTH, or similar HTA agency reports for publication. Triggers include phrases like "convert this report to a journal article", "draft a manuscript from this systematic review", "prepare for journal submission", "extract data for publication", "ingest HTA report", "start drafting".
