Your intelligent GitHub command center -- start here. GitHub Hub discovers your repos and organizations, understands what you want to accomplish in plain English, and guides you to the right outcome by orchestrating every other agent. No commands to memorize. Just talk.

Internal helper agent. Invoked by orchestrator agents via Task tool. Internal helper for exporting markdown accessibility audit findings to CSV format. Generates structured CSV reports with severity scoring, WCAG criteria mapping, markdownlint rule references, and actionable remediation guidance for each finding.

Internal helper agent. Invoked by orchestrator agents via Task tool. Internal helper for applying accessibility fixes to markdown files. Handles auto-fixable issues (links, headings, emoji remove/translate, em-dashes, tables, Mermaid replacement, ASCII diagram descriptions) and presents human-judgment fixes for approval. Invoked by markdown-a11y-assistant via the Task tool - not user-invokable directly.

Internal helper agent. Invoked by orchestrator agents via Task tool. Internal helper for scanning a single markdown file for accessibility issues across all 9 domains.

Mobile accessibility specialist for React Native, Expo, iOS (SwiftUI/UIKit), and Android (Jetpack Compose/Views).
