Skill UI

This skill helps identify explanatory attributes or hypotheses for variations in process metrics such as duration, waiting time, utilization, and rework. It involves checking metadata correlations, statistical evidence, and cohort comparisons to distinguish competing explanations. The method emphasizes evidence-based analysis, avoiding silent assumptions, and framing findings as testable hypotheses rather than definitive causal claims. It supports structured investigation of process efficiency and bottlenecks using specific analytical tools and frozen baseline scopes.

This skill helps vet Telegram channels for advertising by analyzing reach benchmarks, subscriber authenticity, and topic relevance. It guides users to calculate CPM based on actual views and deletion windows, identifying red flags like ad networks or fake subscribers to ensure effective media buying.

This skill identifies hidden risks in code changes beyond the diff and verifies safety by executing real code. It helps determine the blast radius of modifications before merging or designing, ensuring multi-file edits and shared path updates do not break existing clients or systems.

A step-by-step workflow for UI work: understand the project, choose the right plan (new screen, dashboard, polish, simplify, review), then render, fix, and re-check until the result looks right. It helps agents build real, polished interfaces and avoid AI slop.

Write or update a project's DESIGN.md from the colors, type, spacing and components it really uses, with rules agents follow so new screens match. It helps create a single source of truth for UI consistency.

This skill helps design and review API contract tests between providers and consumers. It focuses on verifying wire-level behavior during schema changes, compatibility regressions, and client integration failures. By using local fixtures and existing tools, it ensures type assertions alone are not validation. It classifies changes as breaking or compatible, builds test matrices for various scenarios, and verifies boundaries without provisioning new services.

This skill verifies Python code changes by running mutation testing on modified lines. It ensures every mutant is caught by tests, generating evidence of coverage rather than diffs. It helps confirm that new code is properly tested before completion, using pytest and mutation analysis to validate behavior and trust the change.

This skill helps users find open healthcare jobs in the United States, including nursing, therapy, and allied health roles. It provides access to hourly pay data posted by employers through CareJobs.Now's MCP server or JSON endpoints. Users can search by location, job type, and shift, receiving direct links to apply. It also answers questions about salary ranges and hiring trends across different states and health systems.

This skill helps upgrade Java projects to newer JDK versions like 11 to 17, 17 to 21, or 21 to 25. It detects current versions from build files and guides you to adopt new language features safely. It covers updating build configurations, resolving migration errors, and verifying builds. Use it for modernizing Java codebases without external plugins.

Maintain an operation log and deduplicated document catalog for long-running projects, helping resume work and trace durable document changes across sessions.

AI Elements is a component library built on shadcn/ui designed to help developers build AI-native applications faster. It provides pre-built components for conversations, messages, tool displays, and prompt inputs. Ideal for creating chatbots, AI assistants, or any AI-powered chat interface. Supports React and Next.js with easy CLI installation and full customization options using Tailwind CSS.

This skill ensures browser automation reliability by anchoring actions to stable DOM selectors and semantic roles rather than screen coordinates. It helps workflows survive layout shifts, A/B tests, and viewport changes. Users should inspect the DOM, prioritize data-testid attributes, verify selectors match exactly one element, and wait on state instead of fixed time. It includes error handling for modals and navigation races.
