Flutter accessibility auditing and remediation with WCAG 2.1 level selection (A, AA, AAA) across mobile, desktop, and web platforms. Use when building, auditing, or reviewing widgets for screen reader support, touch targets, focus management, color contrast, text scaling, or motion sensitivity. Begins by asking the WCAG conformance level and target platform(s) before applying level-appropriate, platform-aware criteria.
Best practices for building a Flutter UI package on top of Material — custom components, ThemeExtension-based theming, consistent APIs, and widget tests. Use when user says "create a ui package". Supports app_ui_package template.
Link workspace packages in monorepos (npm, yarn, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@org/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager's workspace commands to fix actual linking.
Integration guide for Morph's WarpGrep (fast agentic code search) and Fast Apply (10,500 tok/s code editing). Use when building coding agents that need fast, accurate code search or need to apply AI-generated edits to code efficiently. Particularly useful for large codebases, deep logic queries, bug tracing, and code path analysis.
Architect PROSE-compliant agent primitives for AI-native development. Use when (1) Building AI-native apps from requirements ("I want an app that...") (2) Making legacy projects AI-native (3) Designing agent workflows (4) Auditing existing primitives for reliability issues. PROSE = Progressive Disclosure, Reduced Scope, Orchestrated Composition, Safety Boundaries, Explicit Hierarchy
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
myfy FrontendModule for server-side rendering with Jinja2, Tailwind 4, DaisyUI 5, and Vite. Use when working with FrontendModule, templates, render_template, static files, Tailwind CSS, or Vite HMR.
Creates syntactically correct mermaid diagrams (flowchart, sequenceDiagram, classDiagram, stateDiagram, erDiagram, gantt, mindmap) following official specifications. Prevents common errors like special characters in labels, subgraph syntax, note misuse, and reserved words. Use when creating or editing mermaid diagrams in documentation or design files.
Expert in Claude Agent SDK development. Use when users ask about SDK API, agent configuration, MCP servers, hooks, permissions, file checkpointing, or when they mention @AGENT_SDK_DOCS.md. Provides accurate API reference, code examples with TypeScript types, and best practices.
Core myfy patterns and conventions for building applications. Use when working with myfy.core, Application, WebModule, DataModule, FrontendModule, TasksModule, UserModule, CliModule, AuthModule, RateLimitModule, or @route decorators.
myfy TasksModule for background job processing with SQL-based queue. Use when working with TasksModule, @task decorator, background jobs, task workers, TaskContext, task retries, or async task dispatch.
myfy CliModule for custom CLI commands with DI injection. Use when working with CliModule, @cli.command decorator, command groups, CLI arguments, CLI options, or myfy app commands.
Validates Solidity implementation against specification documents. Extracts behavior from docs (README, specs, NatSpec) and verifies code matches documented intent. Uses Trail of Bits methodology for divergence detection.
Manipulate images locally using Python and PIL/Pillow. Use when the user asks to resize, crop, rotate, flip, filter, enhance, combine, overlay, watermark, add text to, convert, compress, create, or edit images locally. Also use for thumbnails, borders, color adjustments, transparency, animated GIFs, or extracting image metadata.
Implement, review, or improve CloudKit and iCloud sync in iOS/macOS apps. Use when working with CKContainer, CKRecord, CKQuery, CKSubscription, CKSyncEngine, CKShare, NSUbiquitousKeyValueStore, or iCloud Drive file coordination; when syncing SwiftData models via ModelConfiguration with cloudKitDatabase; when handling CKError codes for conflict resolution, network failures, or quota limits; or when checking iCloud account status before performing sync operations.
Implement, review, or improve accessibility in iOS/macOS apps with SwiftUI and UIKit. Use when adding VoiceOver support with accessibility labels, hints, values, and traits; when grouping or reordering accessibility elements; when managing focus with @AccessibilityFocusState; when supporting Dynamic Type with @ScaledMetric; when building custom rotors or accessibility actions; when auditing a11y compliance; or when adapting UI for assistive technologies and system accessibility preferences.
Build lightweight App Clip experiences for instant iOS app access without full installation. Covers target setup, invocation URL handling, experience configuration, size limits, invocation methods (NFC, QR, App Clip Codes, Safari banners, Maps, Messages), NSUserActivity handling, data migration to the full app via shared App Group containers, SKOverlay for full-app promotion, location confirmation with APActivationPayload, lifecycle considerations, and capability limitations. Use when creating App Clips or configuring App Clip invocation and data migration.
Write, review, debug, and improve bash/shell scripts for any context: CI/CD pipelines (GitHub Actions, GitLab CI, Bitrise), DevOps automation, macOS/Linux system tasks, file processing, and data transformation. Use this skill whenever the user asks to write a shell script, improve an existing one, debug a bash error, or automate any task via command line — even if they just say "make a script that does X" or paste a broken script without explanation. Also trigger for requests involving cron jobs, entrypoints, deploy scripts, migration scripts, or any .sh file.
