Analyze and score test coverage across all testing dimensions -- unit, integration, E2E, load, visual regression, contract, and accessibility. Auto-detects tech stack and test infrastructure, runs existing coverage tools, identifies gaps by category, scores each on a 0-10 scale with weighted overall health, and produces a prioritized remediation plan routing to the right testing sub-skill. Use whe

Autonomous design effectiveness evaluation — visual hierarchy, information architecture, emotional resonance, and craft quality. Produces actionable feedback with specific before/after recommendations.

Set up GitHub authentication for the agent using git (universally available) or the gh CLI. Covers HTTPS tokens, SSH keys, credential helpers, and gh auth — with a detection flow to pick the right method automatically.

Write human-sounding, SEO-optimized blog posts for skills-hub.ai. Use when: 'write a blog post', 'draft a post', 'update blog', 'blog about', 'write about'. Supports styles: tutorial, deep_dive, opinion, listicle, case_study.

Configure device matrix testing across real phones, tablets, and emulators. Sets up Firebase Test Lab, AWS Device Farm, or BrowserStack with smart device selection covering flagships to budget phones, test sharding for parallel execution, flaky test quarantine, and cross-device performance benchmarking. Use when you need to test on multiple devices, validate across screen sizes, catch device-speci

Auto-detects any tech stack, generates and runs exhaustive end-to-end tests. Triggered by "end-to-end tests", "e2e tests", "integration tests", "test the whole app", "generate tests", "test coverage", "write e2e", "run e2e", "full test suite".

Inspect GitHub PR checks, fetch actionable failure logs, summarize the breakage, and propose a local fix plan before changing code.

Check whether global code intelligence tools are installed and configured consistently.

Deterministic 3-cycle loop for gathering codebase context before acting. Broad search → exact source and tests → target-specific docs and setup. Stop after enough context or report what is still missing.

Analyzes mobile app binary size -- asset audit for unused images and font subsetting, code stripping with ProGuard and tree-shaking, on-demand resources, dynamic feature modules, and app thinning strategies. USE THIS SKILL WHEN: - Your app's download size is too large or growing unexpectedly - Someone asks "why is our app so big?" or "how do we reduce app size?" - You need to audit assets (images,

Use when adding CI/CD, creating workflows, auditing GitHub Actions, or fixing action pinning. Creates and audits workflows for SHA pinning and permissions.

Use when conversation context is bloated, constraints are being forgotten, or a compact handoff is needed before continuing work.
