General best practices for Dart development. Covers code style, effective Dart, and language features.
Comprehensive AI prompt engineering safety review and improvement prompt. Analyzes prompts for safety, bias, security vulnerabilities, and effectiveness while providing detailed improvement recommendations with extensive frameworks, testing methodologies, and educational content.
Write effective UI copy including microcopy, error messages, empty states, and CTAs.
Use this skill when crafting LLM prompts, implementing chain-of-thought reasoning, designing few-shot examples, building RAG pipelines, or optimizing prompt performance. Triggers on prompt design, system prompts, few-shot learning, chain-of-thought, prompt chaining, RAG, retrieval-augmented generation, prompt templates, structured output, and any task requiring effective LLM interaction patterns.
Help users integrate Runway audio APIs (TTS, sound effects, voice isolation, dubbing)
TypeScript 6+ guidance for project development, tsconfig configuration, diagnostics, module resolution, deprecations, and modern standard-library typings. Use when building or maintaining TypeScript 6+ projects, debugging compiler behavior, or working through TS 6-specific defaults and tooling such as `#/` subpath imports, `ignoreDeprecations`, `RegExp.escape`, `Temporal`, and `--stableTypeOrdering`. Triggers on typescript 6, ts 6, stableTypeOrdering, ignoreDeprecations, types array, noUncheckedSideEffectImports, baseUrl deprecated, moduleResolution node deprecated, and subpath imports.
Build and migrate iOS, macOS, iPadOS, watchOS, tvOS, and visionOS apps with Apple's Liquid Glass design system (iOS 26+, macOS 26 Tahoe+). Use when creating new SwiftUI apps targeting Apple's 2025+ platforms, migrating existing apps to Liquid Glass, applying .glassEffect(), .backgroundExtensionEffect(), .buttonStyle(.glass), GlassEffectContainer, glass toolbars, glass tab bars, glass sheets, or any Liquid Glass UI work. Also use when the user asks about modern Apple design, navigation patterns with glass, or SwiftUI best practices for the latest OS versions.
Guide the agent on creating visually distinctive, polished Vaadin 25 interfaces that go beyond default theme styling. This skill should be used when the user asks to "make it look good", "improve the design", "style the view", "make it visually appealing", "add polish", "design a UI", "create a beautiful interface", or when building a new view where visual quality matters. Also trigger when the user wants to add animations, visual effects, or build polished component compositions in a Vaadin application.
Diagnose and interpret AE/TE A/B experiments from configuration and report evidence through a defensible decision. Use when the user asks what an experiment means, whether it can roll out, why a result is not significant, why group sizes or exposure are wrong, why treatment results conflict, whether the report is trustworthy, or what to do next. Covers SRM, duration sufficiency, novelty effects, metric conflicts, missing or anomalous data, design reasonableness, data reliability, metric interpretation, trend and segment analysis, root-cause hypotheses, and rollout recommendations. All platform discovery and reads must use ae-cli.
Apply repository-grounded senior engineering judgment to substantial Python work and bounded Python changes with production or cross-boundary risk. Do not use for trivial syntax questions, generic tutoring, or tasks with no Python artifact unless explicitly invoked. Use for writing, review, diagnosis, design, refactoring, or maintenance where correctness, state, effects, concurrency, compatibility, security, reuse, testing, or long-term ownership materially matters.
AI-agent readiness auditing for project documentation and workflows. Evaluates whether future Claude Code sessions can understand docs, execute workflows literally, and resume work effectively. Use when onboarding AI agents to a project or ensuring context continuity. Includes three specialized agents: context-auditor (AI-readability), workflow-validator (process executability), handoff-checker (session continuity). Use PROACTIVELY before handing off projects to other AI sessions or team members.
Detect test smells, overmocking, flaky tests, and coverage issues. Analyze test effectiveness, maintainability, and reliability. Use when reviewing tests or improving test quality.
