What's on the bench.
Shared Instructions
These instructions are common to all GitHub-related agents in this workspace. Every agent MUST follow these rules.
Security Dashboard
GitHub security alerts command center -- triage Dependabot, code scanning, and secret scanning alerts entirely from the editor. Bypasses the color-dependent, focus-trapping security UI that is largely inaccessible to screen readers.
Screen Reader Lab
Interactive screen reader simulation for education and debugging. Takes HTML, JSX, or a component file and produces a step-by-step narration of what a screen reader would announce. Supports reading order, Tab navigation, heading navigation (H key), and form navigation (F key) modes. Not a replacement for real screen reader testing — use testing-coach for actual test plans.
Scanner Bridge
Internal helper that bridges GitHub Accessibility Scanner CI data with the agent ecosystem. Fetches scanner-created issues, normalizes findings, deduplicates against local scans, and tracks Copilot fix status.
Repo Manager
GitHub repository setup and management specialist - scaffolds issue templates, contributing guides, CI workflows, releases, labels, badges, licenses, and open source best practices for any repo.
Repo Admin
Repository administration command center -- add and remove collaborators, configure branch protection, manage webhooks, adjust repository settings, audit access, and synchronize labels and milestones across repos.
Release Manager
GitHub releases command center -- create, edit, and manage releases and their binary assets entirely from the editor. Bypasses the drag-and-drop asset upload and icon-only controls that are inaccessible to screen readers.
Projects Manager
GitHub Projects v2 command center -- create, configure, and manage project boards, views, custom fields, iterations, and item workflows entirely from the editor. Bypasses the drag-and-drop UI that is inaccessible to screen reader users.
PR Review
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.
Playwright Scanner
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).
Office Scan Config
Office document accessibility scan configuration manager. Use to create, edit, validate, or explain .a11y-office-config.json files that control which accessibility rules are enabled or disabled per Office file type (docx, xlsx, pptx). Manages rule profiles, severity filters, and per-project scan customization.
Office Remediator
Office document accessibility remediator for Word (.docx), Excel (.xlsx), and PowerPoint (.pptx). Generates Python scripts for programmatic fixes via python-docx, openpyxl, and python-pptx, and provides step-by-step Microsoft Office UI instructions for manual fixes.
NVDA Addon Development Specialist
Expert in NVDA screen reader addon development -- architecture, APIs, plugin types (globalPlugins, appModules, synthDrivers, brailleDisplayDrivers), manifest format, event/script handling, NVDAObject overlays, tree interceptors, addon packaging, Add-on Store submission, testing with NVDA, braille table and speech dictionary authoring, and internationalization. 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. Handles focus trapping, focus return, escape behavior, and screen reader announcements for overlays. Applies to any web framework or vanilla HTML/CSS/JS.
Mobile Accessibility
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.
Media Accessibility
Video, audio, and streaming media accessibility specialist. Audits captions (WebVTT/SRT), transcripts, audio descriptions, accessible media player controls, live captioning, and WCAG 1.2.x time-based media criteria.
