Skill UI

Performs comprehensive, multi-page Lighthouse audits across an entire website. This tool is a robust, quota-free alternative to services like PageSpeed Insights, making it ideal for large sites or CI/CD pipelines where API limits are a concern. It aggregates key metrics such as performance, accessibility, and SEO scores across all audited routes.

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 tool verifies the consistency and integrity of the Architecture Decision Records (ADR) graph, which is populated by `adr-index`. It checks for common data corruption issues such as dangling references (broken links), supersedure cycles (circular dependencies), and status mismatches. It is ideal for post-import validation and use as a strict CI/CD gate.

Generates a precise, evidence-based installation plan for a project's component catalog (ECC). Instead of loading a full, noisy bundle, this skill analyzes the repository's actual code structure, dependencies, and CI/CD evidence to classify skills, rules, and commands into 'DAILY' (essential) and 'LIBRARY' (referenceable) buckets. It ensures only necessary components are active, optimizing the development environment.

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.

A comprehensive tool for establishing performance baselines across multiple dimensions. It measures Core Web Vitals (LCP, CLS, INP), API latency (p50, p95, p99), and development build efficiency. Essential for detecting performance regressions before merging code, ensuring stability in CI/CD pipelines, and comparing alternative stack implementations.

A comprehensive tool for automated User Interface (UI) testing. It records and replays entire browser sessions, ensuring every test generates a verifiable, replayable artifact (RVF). Use it to validate complex user flows, catch frontend regressions, and establish reliable baselines for continuous integration (CI) pipelines. Supports visual comparison and structured validation steps.

A high-performance utility for executing simple, deterministic code transformations (e.g., removing console logs, converting var to const). This engine leverages a WASM core to perform structural refactoring sub-millisecond, without calling any expensive LLM APIs. Ideal for CI/CD pipelines, automated bulk refactoring, and cost-sensitive development workflows where determinism and speed are paramount.

This guide outlines a comprehensive, agent-focused testing workflow for modern C++ (C++17/20) using GoogleTest and CMake/CTest. It teaches key concepts like the TDD cycle (Red-Green-Refactor), utilizing mocking (gmock) and fixtures for isolation, setting up robust CI/CD integration, and debugging complex issues using sanitizers (ASAN, TSAN) and coverage analysis. Use this when writing, updating, or ensuring the functional robustness of C++ codebases.

Use CronCreate to schedule background workers that must persist even after session restarts. This utility provides various recommended schedules for critical, recurring tasks like security audits, performance optimization, memory consolidation, and documentation generation. It is essential for CI/CD pipelines, continuous monitoring, and maintaining system health.

This tool validates the structural integrity of a Domain-Driven Design (DDD) codebase. It automatically detects cross-context import violations, checks for broken aggregate invariant enforcement, and verifies adherence to established patterns (like repository and event naming conventions). Essential for CI/CD gates and large-scale codebase auditing to prevent architectural leakage.

A comprehensive guide covering modern application deployment strategies, including Blue-Green, Canary, and Rolling deployments, ensuring zero downtime. It also provides deep dives into Docker multi-stage builds, container best practices, and setting up robust CI/CD pipelines using tools like GitHub Actions.
