Your code review command center -- pull PR diffs, before/after snapshots, developer comments, reactions, release context, and generate full review documents (markdown + HTML) in your workspace.
PowerPoint Accessibility
PowerPoint presentation accessibility specialist. Use when scanning, reviewing, or remediating .pptx files for accessibility. Covers slide titles, alt text, reading order, table headers, hyperlink text, duplicate titles, sections, and media accessibility. Enforces Microsoft Accessibility Checker rules mapped to WCAG 2.1 AA.
Playwright Verifier
Internal helper for fix verification using Playwright. After a fix is applied, navigates to the fixed element, runs a targeted axe-core assertion, and reports PASS/FAIL/REGRESSION. Read-only — never modifies files. Can generate Playwright test code that encodes the verification assertion.

Internal helper for behavioral accessibility testing using Playwright. Runs keyboard navigation scans, dynamic state scans, viewport responsive scans, contrast verification, and accessibility tree snapshots against live pages. Read-only — never modifies files.
Performance Accessibility
Audits the intersection of web performance and accessibility. Covers lazy loading announcements, skeleton screen semantics, Cumulative Layout Shift impact on assistive technology, code splitting with accessible loading states, and progressive enhancement patterns.
PDF Scan Config
PDF accessibility scan configuration manager. Use to create, edit, validate, or explain .a11y-pdf-config.json files that control which PDF accessibility rules are enabled or disabled. Manages three rule layers (PDFUA conformance, PDFBP best practices, PDFQ pipeline), severity filters, and preset profiles.
PDF Remediator
PDF accessibility remediator. Extends the PDF audit workflow with actual fix capability. Generates scripts for programmatic fixes (title, language, reading order, tag corrections, alt text) via pdf-lib/qpdf/ghostscript, and provides step-by-step Adobe Acrobat Pro instructions for manual fixes (table structure, complex layouts, form tooltips).
PDF Accessibility
PDF document accessibility specialist. Use when scanning, reviewing, or remediating PDF files for accessibility. Covers PDF/UA conformance, Matterhorn Protocol checks, tagged structure, alt text, language, bookmarks, forms, reading order, and text extraction. Three rule layers - PDFUA (conformance), PDFBP (best practices), PDFQ (quality/pipeline).

Grounded in the official NVDA source code (github.com/nvaccess/nvda) and community development guides.
Notifications Manager
GitHub notifications command center -- read, filter, triage, and manage notifications entirely from the editor. Bypasses the hover-dependent, swipe-gesture notification inbox that is largely inaccessible to screen readers.
Nexus 2
Auto-routing GitHub orchestrator -- describe what you need and Nexus silently routes to the right specialist agent. Unlike GitHub Hub (which presents a menu), Nexus infers your intent from plain English and hands off immediately. Best for experienced users who know what they want.
Modal Specialist
Modal and dialog specialist for web applications. Use when building or reviewing any modal, dialog, popover, sheet, drawer, confirmation prompt, alert dialog, or overlay that appears above page content.

Mobile accessibility specialist for React Native, Expo, iOS (SwiftUI/UIKit), and Android (Jetpack Compose/Views). Audits accessibilityLabel, accessibilityRole, accessibilityHint, touch target sizes, screen reader compatibility, and platform-specific semantics. Use for any React Native or native mobile code review - approximately 60% of web traffic is mobile and most UI accessibility tooling ignores mobile-specific patterns.

Live Region Controller
Live region and dynamic content announcement specialist.
