Skill UI

A comprehensive guide detailing industry-standard best practices for building scalable and maintainable Flutter/Dart applications. This skill covers architectural patterns (MVVM, feature-based design), state management, coding standards (modern Dart features, widget usage), and testing methodologies. Use it for planning, structuring new features, reviewing existing codebases, or refactoring complex logic into robust, testable components.

This skill analyzes React, Tailwind, or HTML interfaces against a comprehensive design rubric (74 rules). It scores the UI from 0-100, identifying common flaws that make interfaces look generic, unfinished, or "AI-generated"—such as mixed corner radii, poor color discipline, or missing states. It provides a prioritized list of actionable fixes to ensure a polished, professional, and user-centric experience before deployment.

A comprehensive Keynote template designed for announcing new products. It guides users through the narrative arc, covering the problem statement, product introduction, key features, pricing tiers, and a clear call to action, all within a polished, professional design.

Provides comprehensive guidance on scheduling AI agent runs, covering external systems like cron and systemd, and built-in schedulers (e.g., Hermes). It details best practices for setting up recurring jobs, implementing heartbeat patterns, and avoiding common pitfalls like tight timers or state loss, ensuring reliable, scheduled automation.

This skill utilizes the built-in macOS `caffeinate` command to prevent the Mac from entering sleep mode. It is essential for guaranteeing uninterrupted workflow during long-running tasks, such as code builds, large downloads, or supervised automation sessions. Users can specify a fixed duration or attach the function to a specific process ID for continuous wakefulness.

This skill drives an existing browser instance using the Chrome DevTools Protocol (CDP). It is essential for complex web automation tasks that require visible interaction, JavaScript execution, or handling authenticated, stateful sessions. Use it when static data fetching is insufficient, such as simulating user logins, interacting with iframes, or performing visual verification. Supports headless and remote environments.

This skill provides a systematic, four-phase workflow for diagnosing and recovering from AI agent failures. It guides the agent to first capture the failure state, diagnose the root cause (e.g., loop, context overflow, state drift), apply minimal containment recovery actions, and finally generate a detailed introspection report, minimizing the need for human intervention.

This comprehensive guide covers best practices for building modern Angular applications. It provides detailed instructions on component architecture, state management using Signals, advanced routing, dependency injection, handling forms (prioritizing Signal Forms), and implementing accessibility (ARIA). It also details setup procedures for new projects and modern rendering strategies like SSR.

A comprehensive guide covering patterns and architectures for automating code execution using LLMs. It spans simple sequential pipelines (e.g., daily dev scripts) to advanced, RFC-driven multi-agent Directed Acyclic Graph (DAG) orchestration. Ideal for building CI/CD style continuous development pipelines, managing complex state, and automating quality gates without human intervention.

This skill utilizes learned patterns and the current state to predict the most optimal next action in a complex, multi-step workflow. It guides the execution flow by checking prediction confidence: high confidence leads to immediate execution, while low confidence triggers a fallback to task list prioritization. Crucially, it continuously learns from completed tasks to update patterns, ensuring improved, self-correcting automation across sessions.

This tool enables web interaction using natural language descriptions instead of complex CSS selectors. By utilizing a specialized page-agent and an LLM-driven tool-call loop, users can simply state their goal (e.g., "Fill the search box with cats and submit"). It is ideal for dynamic web pages, ambiguous structures, or quick, one-shot interactions where robust selector writing is impractical. The system provides graceful degradation if the advanced page-agent is unavailable.

This tool serves as a persistent memory and state manager for complex coding projects within the Claude environment. It allows users to initialize new projects with structured metadata, track detailed session progress (including summaries, decisions, and next steps), and save the entire context reliably. By ensuring project continuity across disconnected sessions, it drastically improves the flow and consistency of the development workflow.
