Generate comprehensive unit tests with edge cases, error paths, and boundary values. Auto-detects test framework (Vitest, Jest, pytest, go test, flutter_test, RSpec, cargo test, JUnit), scans for untested functions by priority, adopts existing test conventions, generates tests with proper mocks, runs them, and self-heals failures in up to 3 iterations. Measures coverage before and after. Use when you need to add unit tests, increase code coverage, test edge cases, or verify error handling paths.

Turn a design into production-quality frontend code: extract a design system with tokens and components, make layouts responsive across breakpoints, add dark mode with WCAG-compliant theming, then run a UX audit to validate everything. Use when implementing UI from Figma, adding theming, making an app responsive, or overhauling frontend design consistency.

Security audit and vulnerability assessment for any codebase. Scans for authentication bypasses, missing auth middleware, broken JWT validation (algorithm confusion, weak secrets, missing expiry), OAuth state and PKCE flaws, IDOR and horizontal privilege escalation, vertical privilege escalation via role manipulation, SQL injection, NoSQL injection, XSS (stored, reflected, DOM), command injection, path traversal, SSRF, CSRF, hardcoded secrets and API keys (sk_live_, AKIA, ghp_), .env and credential file exposure, PII leaking in logs and error responses, overfetching sensitive fields, CORS misconfiguration, session fixation, missing secure/httpOnly/sameSite cookie flags, and Firebase/Firestore rule weaknesses. Produces a severity-ranked findings report with exploit scenarios and fix recommendations. Covers OWASP Top 10.

Triggers on: clean up, dead code, unused imports, lint, technical debt cleanup, spring cleaning, tidy up the codebase, remove dead code, code hygiene, declutter.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Learn to build and publish your own AI agent skills -- from idea to published on skills-hub.ai

Reconstructs the development cycle from git history, distills sequential/parallel patterns, and produces actionable insights for improving future iterations. Triggers: recall, retrospective, development analysis, what happened, dev cycle analysis.

Create a reusable, self-healing, self-evolving global skill — either from the current conversation context OR from a plain-language description of a workflow. Triggers on: 'turn this into a skill', 'make a skill from this', 'skillify this', 'capture this as a skill', 'save this workflow as a skill', 'create a skill for this', 'make this repeatable', 'skill this up', 'build me a skill that does X', 'I want a skill for Y', or any time a workflow just played out and the user wants to preserve it. Invoke even if the user only hints at wanting to reuse what just happened.

Architect-level story review with component reuse, domain consistency, data privacy, service architecture, and infrastructure checks. Design review before coding or implementation validation after.

Scan a codebase for broken links — dead URLs in Markdown/HTML, broken file references, invalid import paths, stale anchor links, and broken cross-doc references — then auto-fix what it can: replace dead URLs with Wayback Machine archives, update moved file paths via git history, remove anchors that no longer exist, and flag what needs human review. Self-healing: learns fix patterns and improves over iterations. Use when: 'fix broken links', 'check links', 'dead links', 'broken urls', 'link rot', 'fix references', 'validate links', 'stale links', 'broken imports'.

Audit and fix responsive design issues across all breakpoints. Scans for fixed widths that cause mobile overflow, missing media query variants, non-responsive images, undersized touch targets below 48px, unreadable typography, and horizontal scroll violations. Auto-detects framework (Flutter, Tailwind, React, Vue, Angular) and responsive system, then fixes layouts with proper flex/grid, clamp-based fluid typography, responsive image sizing, and adequate touch target spacing. Verifies every screen at mobile (375px), tablet (768px), desktop (1280px), and wide (1920px). Use when you need to fix mobile layout bugs, audit responsive breakpoints, fix overflow issues, ensure touch targets meet accessibility minimums, or verify no horizontal scroll at any viewport width.

Learn effective AI prompting through practice -- good vs bad prompts, context management, the STAR framework, and advanced techniques

Extract and formalize a design system from existing UI code. Scans for every hardcoded color, font size, spacing value, border radius, and shadow across the codebase, deduplicates near-identical values, generates framework-appropriate tokens (CSS custom properties, Tailwind config, Flutter ThemeData, SCSS variables), builds a component inventory with token coverage ratings, and replaces all hardcoded values with token references. Use when you need to create design tokens, consolidate inconsistent styles, audit component consistency, replace magic numbers with named values, or set up a shared design language across a project.

Map your goal to a multi-skill workflow -- suggests Combo chains, generates custom pipelines, and explains each step

Add purposeful motion to interfaces using modern CSS — scroll-driven animations, view transitions, @starting-style, and GPU-accelerated transforms. Zero JS animation libraries needed. Supports web and Flutter. Use when: 'add animation', 'animate', 'add motion', 'transitions', 'scroll animation', 'page transitions', 'loading animation', 'micro-interactions'.

Review API design against REST best practices and internal consistency.
