Skill UI

OpenRouter provides a unified API gateway to access leading AI models (OpenAI, Anthropic, Google, Meta, etc.) from a single endpoint. This skill is essential for developers who need to compare model performance (latency, tokens) across different providers, build resilient cross-provider fallback workflows, or manage complex AI pipelines without writing provider-specific code. It supports feature normalization and BYOK (Bring Your Own Key) for high-volume production use.

This skill provides a comprehensive guide to understanding OpenRouter's API billing structure. It teaches users how to accurately calculate costs based on prompt (input) and completion (output) tokens. Users can utilize provided scripts to estimate costs, check credit balances, and implement cost-saving strategies like using `:floor` or `:free` model variants. Ideal for budgeting, performance comparison, and production cost tracking.

A comprehensive guide to building production-grade evaluation systems for Large Language Models (LLMs). This skill covers advanced methodologies, including Direct Scoring and Pairwise Comparison, alongside critical techniques for mitigating systematic biases (e.g., Position Bias, Length Bias). Learn how to select appropriate metrics and structure prompts to ensure reliable, consistent, and objective quality assessment across various AI applications.

This framework teaches how to create "Grand Slam Offers"—packages so valuable that rejection feels foolish. It guides users to optimize the perceived value using the Value Equation (Dream Outcome, Likelihood, Time Delay, Effort). Learn how to strategically bundle core products with bonuses, guarantees, and scarcity mechanisms to eliminate price comparison and achieve market dominance.

This skill monitors for regressions on deployed URLs following deployments, merges, or dependency upgrades. It performs comprehensive checks including HTTP status, console errors, network failures, performance metrics (LCP/CLS/INP), and crucial API endpoint health, ensuring service stability in production or staging environments. Supports quick checks, continuous monitoring, and differential comparison against baselines.

An AI persona wrapper that adopts the style of a traditional Chinese mother to enforce productivity. It uses emotional pressure, social comparison, and strict coaching protocols to ensure tasks are completed thoroughly, pushing the AI to debug better and avoid excuses.

This skill automatically generates an interactive SQL Notebook designed to validate changes in dbt models or snapshots. It processes changes identified from a GitHub PR or local repository, generating comparison queries that compare 'before' (production) and 'after' (development) data states. It is essential for embedding data observability and quality checks into CI/CD pipelines.

This advanced tool functions as a competitive intelligence partner for Product Managers. It moves far beyond simple feature comparison, helping users map the entire market landscape, identify underlying Jobs-to-be-done, uncover competitor positioning gaps, and generate actionable strategic recommendations. Use it when you need to define a product's unique value proposition or evaluate market threats.

This skill generates a complete, standalone, and highly structured pricing page in standalone HTML. It automatically respects the active design system (colors, typography, components) and supports defining 2-4 plan tiers, including feature cards, comprehensive comparison tables, and an FAQ section. Ideal for product marketing and sales-focused websites.

Unship is a dedicated local workflow for front-end developers to compare multiple AI-generated UI alternatives (such as layouts, copy, or flows) directly within a running application environment. Instead of committing to one generated version, it adds temporary source-level variants, allowing for visual comparison. After the user selects the final version, the skill automatically cleans up all unused temporary code and attributes, ensuring a clean, production-ready codebase. Note: This tool is for local iteration only, not for production A/B testing or analytics.

A comprehensive framework for conducting deep competitive analysis, providing structured insights for product decision-making and business strategy. It guides the creation of detailed reports, including feature comparison matrices, pricing models, market positioning maps, and win/loss analyses. Ideal for product managers, strategists, and sales teams developing battlecards.

This comprehensive skill generates a structured competitive analysis document for any product or market. It is ideal for strategic planning, creating investor decks, or sales enablement. The output includes a positioning map, detailed feature comparison table, messaging gap analysis, SWOT summary, and actionable strategic recommendations to define your market edge.
