Storybook 10 testing patterns with Vitest integration, ESM-only distribution, CSF3 typesafe factories, play() interaction tests, Chromatic TurboSnap visual regression, module automocking, accessibility addon testing, and autodocs generation. Use when writing component stories, setting up visual regression testing, configuring Storybook CI pipelines, or migrating from Storybook 9.
Implements Syncfusion .NET MAUI Chips (SfChip or SfChipGroup). Use when working with chips, tags, tag controls, selection chips, input chips, or filter chips in .NET MAUI applications. Covers chip types, chip customization, chip events, chip selection, chip groups, remove chips, close button chips, and chip data binding.
Use this skill for ASP.NET MVC apps needing Excel-like UI using the Syncfusion Spreadsheet Component. Trigger for creating, viewing, editing Excel (.xlsx, .xls, .xlsb) and CSV files; embedding spreadsheet editors; data binding from APIs/JSON; using formulas, charts, validation, filtering, or conditional formatting. Also trigger when users reference spreadsheet files ("open xlsx", "load Excel file", "add Syncfusion spreadsheet", "bind data to spreadsheet"). Do NOT trigger for standalone file processing without UI components.
Checks email quality before sending via Mailgun Inspect API. Use when previewing emails across clients, checking accessibility (WCAG), validating links, validating images, or analyzing email HTML/CSS compatibility.
Build alternative browser engines using BrowserEngineKit. Use when developing a non-WebKit browser engine for iOS in the EU, managing web content rendering processes, configuring GPU and networking processes for browser functionality, checking device eligibility for alternative engines, or working with BrowserEngineKit entitlements.
Hunt for exploitable, bounty-worthy security issues in repositories. Focuses on remotely reachable vulnerabilities that qualify for real reports instead of noisy local-only findings.
Terminal-based spreadsheet TUI tool written in Go for editing CSV files in the terminal with vim-like keybindings
Improves typography by fixing font choices, hierarchy, sizing, weight, and readability so text feels intentional. Use when the user mentions fonts, type, readability, text hierarchy, sizing looks off, or wants more polished, intentional typography.
Security audit and vulnerability scanning for AI agent skills before installation. Detects prompt injection in SKILL.md files, dangerous code patterns (eval, exec, subprocess), network exfiltration, credential harvesting, dependency supply chain risks, file system boundary violations, and obfuscation. Produces PASS/WARN/FAIL verdicts with remediation guidance. Use when evaluating untrusted skills, pre-install security gates, or auditing skill repositories.
This skill should be used when a team wants to create or refine the design guidelines document — for example "create the design steering doc", "document our design system", "write the design principles", "document our component patterns", "set up the design guidelines", or "update the design doc". Generates docs/steering/DESIGN.md as a living document capturing design principles, the design system, tokens, component patterns, and accessibility standards. Generated once and refined — not regenerated from scratch.
Verify your own completed code changes using the repo's existing infrastructure and an independent evaluator context. Use after implementing a change when you need to run unit or integration tests, check build or lint gates, prove the real surface works with evidence, and challenge the changed code for clarity, deduplication, and maintainability. If the repo is not verifiable yet, hand off to `agent-readiness`; if you are reviewing someone else's code, use `review`.
Integrate Sinch In-App Voice and Video SDK for real-time calling in Android, iOS, or JavaScript apps. Use when the user mentions In-App Calling, VoIP integration, WebRTC with Sinch, app-to-phone calling, video calling, or building voice/video features in a mobile or web app.
