Accessibility testing for web applications using Playwright (@playwright/test) with TypeScript and axe-core. Use when asked to write, run, or debug automated accessibility checks, keyboard navigation tests, focus management, ARIA/semantic validations, screen reader compatibility, or WCAG 2.1 Level AA compliance testing. Covers axe-core integration, POUR principles (perceivable, operable, understandable, robust), color contrast, form labels, landmarks, and accessible names.

To ensure the application is usable by people with disabilities, complying with WCAG standards and improving SEO/UX. Use when: During development of UI components; Before major releases.

Accessibility testing toolkit using Selenium WebDriver 4+ with Java 21+ and axe-core engine. Use when asked to validate WCAG 2.1/2.2 compliance, scan pages or components for a11y violations, test keyboard navigation, audit color contrast, check ARIA semantics, generate accessibility reports, filter axe rules, debug screen reader issues, or implement POUR principles (perceivable, operable, understandable, robust).

To allow incompatible interfaces to work together by wrapping an object in an adapter that translates its interface into one that a client expects. Use when: When integrating a third-party library whose interface doesn't match your application's internal requirements; When you want to standardize multiple different implementations of a service (e.g., different payment gateways); When you need to provide a stable interface while the underlying dependency is subject to change.

To implement a scalable permission system where users have roles, and roles have granular permissions. Use when: B2B SaaS applications (Admin, Editor, Viewer); Systems with complex access requirements.

Browser automation CLI for AI agents. Use for website interaction, form automation, screenshots, scraping, and web app verification. Prefer snapshot refs (@e1, @e2) for deterministic actions.

Visual UI annotation tool for AI agents. Drop the React toolbar into any app — humans click elements and leave feedback, agents receive structured CSS selectors, bounding boxes, and React component trees to find exact code. Supports MCP watch-loop, platform-specific hooks (Claude Code / Codex / Gemini CLI / OpenCode), webhook delivery, and autonomous self-driving critique with agent-browser.

To structure autonomous AI systems that can reason, plan, and execute tools to solve complex, multi-step problems using patterns like ReAct and Multi-Agent orchestration. Use when: When the task requires multiple distinct steps (e.g., "Find the price of BTC and email me the summary"); When the LLM needs to interact with the outside world (APIs, Databases, Web Search); When the workflow is non-linear and depends on intermediate results.

Guides correct setup of pydita's DitaContext for a DITA processing pipeline. Use this skill when you need to wire together resolveMap(), KeyspaceManager, DitavalFilter, and DitaContext, or when a pipeline is failing because of incorrect initialisation order, missing DITA-OT configuration, or a mismatched errors dictionary.

Analyzes a DITA topic or map file for quality and maintainability issues beyond basic DTD validity. Use this skill after validate-dita-topic or validate-ditamap when you want to check shortdesc length, topic size, step count, nesting depth, conref chain problems, keyref-vs-href balance, duplicate content, and empty elements. Returns structured JSON with categorized findings.

Assists with DITAVAL conditional processing files for filtering and flagging DITA content at build time. Use this skill to validate an existing DITAVAL file, generate a new DITAVAL template from a list of conditions, or understand action priority and style-conflict resolution rules. Returns structured JSON for validation or XML output for generation.

Reference skill for pydita's error recording and reporting model. Use this skill when you need to understand how errors are accumulated in the shared errors dict, work with ErrorRecord and SEVERITY, filter errors by severity level, or produce a formatted error report using reportErrors(). Covers DitaContext.recordError() and Logger/ConsoleLogger helpers.

Generates a valid DITA 1.3 bookmap template. Use this skill when you need a correctly structured starting point for a DITA bookmap with booktitle, bookmeta, frontmatter, chapter placeholders, appendix, and backmatter scaffolding. Output includes the correct DOCTYPE declaration.

Generates a valid DITA 1.3 XML topic template for a given topic type. Use this skill when you need a correctly structured starting point for concept, task, reference, troubleshooting, glossentry, or base topic authoring. Output includes the correct DOCTYPE declaration, required elements, and commonly used optional elements pre-scaffolded.

Generates a valid DITA 1.3 map template. Use this skill when you need a correctly structured starting point for a DITA map with topicref placeholders, key definitions, and an optional relationship table. Output includes the correct DOCTYPE declaration.

Scans one or more DITA 1.3 topics and automatically generates keydef entries and keyref suggestions. Use this skill when you want to enforce reuse-first authoring, detect repeated inline text or repeated hrefs that should be centralised in the map, or migrate a set of topics to use keyrefs instead of hard-coded values. Returns ready-to-paste keydef XML plus a change list showing exactly which elements to update.

Systematic implementation using APEX methodology (Analyze-Plan-Execute-eXamine) with parallel agents, self-validation, and optional adversarial review. Use when implementing features, fixing bugs, or making code changes that benefit from structured workflow.

Review a markdown specification across business logic, architecture, performance, security, testing, DevOps/CI/CD, dependencies, standards, UX, documentation, code quality, and maintainability. Generates a structured review, risk register, test plan, implementation tasks, and dimension scores (0–10).

Guide for creating effective skills for software development. Use this skill when: (1) users want to create a new skill, (2) users want to update an existing skill, (3) users ask about skill structure or best practices, (4) users need help writing SKILL.md files.
