Use when writing R code that manipulates expressions, builds code programmatically, or needs to understand rlang's defuse/inject mechanics. Covers: defusing with expr()/enquo()/enquos(), quosure environment tracking, injection with !!/!!!/{{, symbol construction with sym()/syms(). Does NOT cover: data-mask programming patterns (tidy-evaluation), error handling (rlang-conditions), function design (designing-tidy-r-functions).
Analyzes files modified with git commands and creates appropriately granular commits in logical units. Only activates when the skill name (committer) is explicitly specified, such as "/committer", "use the committer skill", or "commit with committer". Does not activate for general requests like "commit" or "git commit".
Generate shareable paper summaries for Discord/Slack/Twitter. Use when user provides arxiv paper(s) and wants a digestible summary to share. Triggers on phrases like "논문 요약", "paper summary", "share this paper", "디스코드에 공유", "summarize for sharing". Produces insight-centered single-paragraph summaries that explain WHY research matters, not just WHAT it does.
Investigate traffic anomalies, spikes, and service degradation on Cloudflare-protected domains. Uses Cloudflare MCP tools for GraphQL analytics, JA4 fingerprint analysis, bot/WAF security scoring, and incident reporting. Use this skill whenever traffic spikes, service overloads, 429 errors, circuit breaker events, Cloudflare analytics, or domain performance issues are mentioned — even if the user doesn't explicitly say "traffic spike". Also triggers when asked to check Cloudflare data for any domain.
Explain code in detail - what it does, how it works, and why. Use when you need to understand unfamiliar code or explain code to others.
Instant visual verification via screenshots. For quick checks like 'does button look blue', 'is layout centered', 'header look right on mobile'. Fast alternative to formal testing - just look and confirm. Use when user wants visual inspection without creating test files.
Strategic discovery of a project's capabilities from a solutions architect perspective. Deploys parallel discovery agents to map architecture, inventory features, and assess infrastructure, then synthesizes findings into a capabilities report with strategic improvement recommendations. Use when user says "explore", "what does this do", "project overview", "capabilities", "feature inventory", or asks about strategic direction.
Use this skill when the user doesn't yet know what to test. This is the "learn the site first" step — for unfamiliar websites, new projects, or any situation where Feature/Persona artifacts don't exist yet. Use when the user: gives a URL with no specific test in mind, asks what features or flows a site has, wants to explore or walk through a site, is new to a project, or says "explore before we test". Also use for bare "test [URL]" commands with no further context. Do not use when Feature artifacts already exist or the user references specific known tests or bugs.
A clear, concise description of what this skill does (1-2 sentences). Focus on the VALUE it provides to the user.
Vitest testing framework patterns for test setup, async testing, mocking with vi.*, snapshots, and test performance (formerly test-vitest). This skill should be used when writing or debugging Vitest tests. This skill does NOT cover TDD methodology (use test-tdd skill), API mocking with MSW (use test-msw skill), or Jest-specific APIs.
Generate a personalized portfolio site from agent-reference reports and deploy it to GitHub Pages. The site reflects the user's working style as observed by their AI collaborators — AI analyzes the reports, proposes a design concept, scaffolds an Astro site with concept-based theming, and deploys to {username}.github.io. Use this skill whenever the user asks to "build my portfolio", "create portfolio site", "make a site from my reports", "deploy to github pages", "github.io site", or says things like "포트폴리오 사이트 만들어줘", "사이트 배포해줘", or wants to turn agent-reference reports into a live website. Also triggers when the user has agent-reference reports ready and wants to publish them as a site, wants a personal site generated from AI collaboration data, or asks to update/redeploy an existing agent portfolio. Do NOT use for general Astro development, generic website building, agent-reference analysis without site generation, or resume writing that does not involve deploying a site.
Write, review, or improve UIKit code following best practices for view controller lifecycle, Auto Layout, collection views, navigation, animation, memory management, and modern iOS 18–26 APIs. Use when building new UIKit features, refactoring existing views or view controllers, reviewing code quality, adopting modern UIKit patterns (diffable data sources, compositional layout, cell configuration), or bridging UIKit with SwiftUI. Does not cover SwiftUI-only code.
