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.

Generate comprehensive unit tests with edge cases, error paths, and boundary values. Triggers: 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..

Scaffolds a browser-based game with Phaser 3, PixiJS, or Three.js including game loop, asset pipeline, responsive canvas, input handling, audio, save/load, and deployment to itch.io or web. Triggers: on: "web game", "browser game", "html5 game", "phaser game", "pixi game".

Multi-pass editor that removes AI-writing tells from drafted content — eliminates filler phrases, balances sentence length, restores opinion and voice, and strips em-dash overuse so posts sound human and opinionated rather than ChatGPT-generic..

Add purposeful motion to interfaces using modern CSS — scroll-driven animations, view transitions, @starting-style, and GPU-accelerated transforms. Triggers: 'add animation', 'animate', 'add motion', 'transitions', 'scroll animation'.

Comprehensive autonomous design quality audit across accessibility (WCAG 2.2), performance, theming, responsive/adaptive design, and anti-pattern detection. Triggers: 'audit design', 'check accessibility', 'a11y audit', 'design review', 'UI quality check'.

Final autonomous quality pass before shipping. Fixes alignment, spacing, consistency, typography hierarchy, color harmony, motion timing, and every micro-detail that separates good from great..

Pre-deploy verification gate. Checks git status, build, tests, migrations, secrets, and commit conventions. Reports READY or NOT READY. Read-only, no changes. Trigger words: preflight, pre-deploy check, ready to deploy, deployment checklist.

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..

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.

HTML-first hi-fi design skill: interactive prototypes, slide decks, animation demos, design variant exploration, visual direction advising, and expert critique. Triggers: make a prototype, design demo, interactive prototype, HTML presentation, animation demo.

Scan codebase for Martin Fowler's catalog of code smells: god classes, long methods, feature envy, data clumps, primitive obsession, shotgun surgery, message chains, and more. Triggers: code feels messy, before a major refactor, to find maintainability problems.

Deep codebase cleanup — kills dead code, fixes all lint/format warnings, removes orphaned files, cleans stale TODOs, strips security hazards, tightens TypeScript strict mode, and organizes imports. Triggers: clean up, dead code, unused imports, lint, technical debt cleanup.

Generate Mermaid architecture diagrams from your codebase. Produces C4 context and container diagrams, sequence diagrams for key flows, ER diagrams from database schemas, and module dependency graphs. Use when you need architecture diagrams, system diagrams, database ERD, sequence diagrams, dependency visualization, or C4 model diagrams.

Builds Flutter applications from videos, screenshots, descriptions, or app clone requests. Triggers on: flutter app, build a mobile app, replicate this app in Flutter, build from video, build from screenshots, clone this app, build an app, make an app like, recreate this UI.

Implement complete dark mode for any frontend project. Auto-detects theme system (Flutter ThemeData, Tailwind dark class, CSS variables, MUI, Chakra UI, styled-components), generates a dark color palette with proper surface elevation hierarchy and desaturated brand colors.

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

Persist, summarize, and reload agent context between sessions — writes a structured session log to CLAUDE.md / AGENTS.md / .hermes.md, snapshots decisions before destructive ops, and resumes long-running goals without re-briefing. Works with any coding agent.

Scaffold a production-ready native Android app -- generate a complete Kotlin project with Jetpack Compose UI, MVVM architecture, Hilt dependency injection, Room database with offline-first caching, Retrofit and OkHttp networking with auth interceptors.

Review API design against REST best practices and internal consistency. Triggers: you need to review an API, audit REST endpoints, check API consistency, fix HTTP status codes, add pagination.

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

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.

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