Skill UI

Optimizes prompts for LLMs to cut token usage, lower costs, and boost response quality by analyzing, condensing, and rewriting instructions; useful when teams need faster, cheaper, clearer AI conversations.

This skill coordinates the complex parallel execution of end-to-end, integration, and unit tests across multiple frameworks (e.g., Jest, Playwright, pytest) and CI/CD environments. It manages test splitting, worker allocation, tiered execution strategies, and aggregates results into unified reports. Ideal for optimizing the testing lifecycle and ensuring robust quality assurance in large-scale, multi-component applications. Key functions include intelligent retry logic for flaky tests and building CI pipelines (e.g., GitHub Actions matrix).

Orchestrates multiple agents for complex workflows, decomposing feature, review, refactor, test, or documentation requests into parallel subtasks tracked via cc-mirror and TodoWrite for live visibility.

A specialized skill designed for agents to proactively identify, analyze, and strategize high-impact contributions within trending Open Source repositories. It systematically performs repository discovery, extracts targeted issues (like 'help wanted' or 'good first issue'), and conducts deep feasibility analysis (including mergeability and complexity). Finally, it generates a structured 'Contribution Dossier' with actionable plans, significantly accelerating the process of becoming a top-tier OSS contributor.

Guides marketers through page-level conversion rate optimization by assessing value proposition clarity, headline effectiveness, CTA strength, visual hierarchy, trust signals, objection handling, and friction points to generate quick wins, prioritized fixes, tests, and copy alternatives.

Orchestrate PagerDuty incidents, services, on-call schedules, and analytics through Composio’s toolkit using Rube MCP, with mandatory schema discovery and active connections before each workflow.

This skill enables the coordination of multiple specialized AI agents within a single session. It is designed for complex, multi-domain tasks such as comprehensive code reviews, security audits, or full-stack feature implementations. It coordinates expertise across various domains (backend, frontend, testing, architecture) to provide holistic analysis and actionable recommendations.

Guides users through password hash generator tasks within the Security Fundamentals stack, outlining best practices, secure coding patterns, and validation checks tailored for authentication workflows.

Automates guidance on evaluating password quality, recommending best practices, implementing validators, and verifying compliance within security fundamentals workflows.

Auto-activating security skill that guides path traversal finder investigations, shares patterns and best practices, and produces validated code/configurations within Security Fundamentals.

This skill provides expert guidance on integrating major payment processors like Stripe and PayPal. It covers end-to-end checkout flows, subscription billing, secure webhook handling, and strict PCI compliance requirements. Use this when building any feature involving financial transactions to ensure reliability and adherence to security best practices.

This guide provides comprehensive principles for modern game development, covering engine selection (Unity, Unreal, Godot), platform integration (Steam features, console compliance), input abstraction, and performance optimization techniques. It helps developers make informed decisions when building cross-platform games for PC and console environments.
