Validates completeness and consistency of the project architecture against all GDDs. Builds a traceability matrix mapping every GDD technical requirement to ADRs, identifies coverage gaps, detects cross-ADR conflicts, verifies engine compatibility consistency across all decisions, and produces a PASS/CONCERNS/FAIL verdict. The architecture equivalent of /design-review.
Refactor legacy codebases, migrate outdated frameworks, and implement gradual modernization. Handles technical debt, dependency updates, and backward compatibility. Use PROACTIVELY for legacy system updates, framework migrations, or technical debt reduction.
This skill should be used when the user asks about MJML syntax, components, or attributes, when writing or editing MJML email templates, when creating responsive email layouts, when troubleshooting MJML rendering issues, or when asking about email client compatibility.
Safe code migrations with backward compatibility and reversibility. Use when upgrading dependencies, changing database schemas, API versioning, or transitioning between technologies.
SUPERSEDED by /brand-assets (brand-kit). Use /brand-assets for new projects. This skill remains for backward compatibility with projects not yet migrated to brand.yaml. Generate deterministic, template-based Open Graph cards with Satori. Use when: creating OG images for blog posts, product pages, changelogs, or comparison pages. Complements /og-hero-image (AI creative) with consistent, branded templates. Keywords: og image, open graph, satori, social card, meta image, twitter card.
Use when writing any code - enforces clean architecture with descriptive names, real implementations, no backward compatibility concerns, and no lint suppressions
Use when a user mentions Scandit, data capture SDK, barcode scanning products, smart data capture, choosing a scanning product, comparing scanning features, supported barcode symbologies, system requirements, device compatibility, or Scandit pricing. Helps choose the right Scandit product (SparkScan, Barcode Capture, MatrixScan, Smart Label Capture, ID Capture, etc.), points to the correct documentation and sample apps for their platform, and hands off to implementation skills.
This skill must be used when initializing, maintaining, and executing by-harness workflows. It applies to scenarios where users mention by-harness, harness, initialization, continuous task decomposition, executing feat, plan/build/qa/fix, session_close, automatic resumption, runtime upgrade, or need to issue Java Gate, Distributed Java Gate, and three-tier frontend specifications to constrain model coding. This skill generates independent closed-loop scaffolding, sharded task storage, session closure tools, runtime upgrade tools, and issues Java hard rule gates, distributed Java coding contracts, three-tier frontend specifications, and BYAI HTML visual references; feature_list is only used as a legacy compatibility mirror.
Build browser automation and web scraping with Playwright on your local machine. Prevents 10 documented errors including CI timeout hangs, extension testing failures, and Ubuntu compatibility issues. Includes stealth mode for anti-bot bypass, authenticated sessions, infinite scroll handling, screenshot/PDF generation, and v1.57 Speedboard performance analysis. Use when: automating browsers, scraping protected sites, testing with real IPs, bypassing bot detection, generating screenshots/PDFs, or troubleshooting "target closed", "page.pause() hangs CI", "permission prompts block tests", or "Ubuntu 25.10 installation" errors.
Dead code & legacy audit worker (L3). Checks unreachable code, unused imports/variables/functions, commented-out code, backward compatibility shims, deprecated patterns. Returns findings.
Use when writing or reviewing asyncio code in Jupyter notebooks or '#%%' cell workflows — structuring event-loop ownership, orchestrating async tasks, or choosing compatibility strategies. Also use when hitting RuntimeError: This event loop is already running, asyncio.run() failures in cells, or tasks silently never completing.
WCAG 2.1/2.2 compliance, WAI-ARIA implementation, screen reader optimization, keyboard navigation, and accessibility testing expert. Use PROACTIVELY for accessibility violations, ARIA errors, keyboard navigation issues, screen reader compatibility problems, or accessibility testing automation needs.
