Build and review Python tests with pytest. Use reusable setup, simulated external services, and multiple input cases to check behavior, then measure coverage—the proportion of code exercised by tests—and follow a test-first development cycle.
Coordinate a new feature from research and planning through tests, implementation, review, and commit. Assign phases to matching ECC agents, write failing tests before implementation, and pause for approval of the plan and before committing.
Guides Kotlin HTTP server development with Ktor through examples for API routes, authentication, JSON conversion, and WebSockets. Shows how to organize application components with Koin and verify routes and authentication using integration tests.
Build Kotlin database access with JetBrains Exposed, a library that maps database records to code. Apply examples for queries, transactions, reusable connections, schema migrations, and repository interfaces that separate database operations from business logic.
Review healthcare applications for exposure of patient and staff information. Classify sensitive data, design access restrictions for individual database rows, record data access and changes, and check common leaks through logs, URLs, and browser storage.
Gather relevant code and background for subagents, agents assigned part of a larger task. Search broadly, assess each file, identify missing information, and refine the search for up to three cycles to assemble context for bug fixes or feature work.
Review a feature or proposal from four perspectives: product management, architecture, development, and quality assurance. Get each role’s concerns and first actions, followed by a summary of shared priorities and unresolved disagreements.
Write or review Dart and Flutter apps with practical patterns for state management, navigation, networking, error handling, and tests. Use code examples to handle missing values, organize widgets, and connect login status to routing.
Build shared interfaces for Android, iOS, Desktop, and Web with Compose. This skill guides screen state, navigation, reusable components, themes, and rendering performance, including ways to handle interface differences between platforms.
Integrate single-page extraction into an application using Firecrawl scrape. Retrieve Markdown, HTML, links, screenshots, metadata, or structured data from a known URL, and configure how recently cached content may be reused.
Build Claude Code hooks, automated checks triggered by events such as tool use or session start. The guidance covers prompt-based decisions, command scripts, configuration, testing, and debugging for validation and workflow automation.
Build MCP servers that let AI access actions and data using mcp-use. The guide covers project setup, reusable prompts, interactive React interfaces, authentication, error handling, and deployment, with reference files for each area.
Review Spec Kit code changes against relevant design documents, tests for expected and unwanted behavior, evidence that bug fixes prevent recurrence, and repository terminology. Findings identify the document sections behind design mismatches.
Turn approved mockups, design plans, or written descriptions into HTML and CSS using Pretext. Build dynamic layouts where text reflows and heights are calculated, choosing Pretext patterns suited to the design.
Develop and fix code by first writing a failing test, then making it pass and improving the implementation. The skill follows the project's testing tools and checks both the intended behavior and existing functionality.
Build responsive interfaces that follow an existing design system and support accessible interaction. Covers component structure, state management, keyboard controls, and loading, empty, and error states, with checks across screen sizes and assistive tools.
Check project dependency versions and consult the relevant official documentation before writing framework-specific code. Produce implementations with source links, identify deprecated APIs, and flag unverified approaches or conflicts between documentation and existing project patterns.
Research MCP connections, which let agents use external tools, and vendor integrations for Paperclip. Produce an evidence-backed planning pull request, obtain human approval for its exact revision, then implement and verify each approved connection separately.
Implement purposeful animations for existing interfaces or an agreed UI brief. It selects motion based on purpose and usage frequency, then handles timing, interrupted interactions, exits, and reduced-motion preferences while reusing the project’s tools and design values.
Build interface components with shadcn/ui, focusing on clear structure and accessibility so more people can use them. Pair the implementation work with the Stitch design loop to move from design iteration to working components.
Turn Figma designs into production-ready frontend code that closely matches the original visuals. Use it to hand design frames directly to a frontend agent and guide implementation toward a faithful reproduction of the design.
Create project-specific rules for turning Figma designs into code. Bring design tokens, shared values such as colors and spacing, together with naming conventions and lint rules for automated checks in one reference.
Implement animated effects, transitions, and movement in Flutter apps. Use it when adding motion to native iOS and Android app interfaces, with support for turning requests for animation into implementation work.
Build web animations with GSAP plugins for text, SVG graphics, dragging, scrolling, and layout changes. It guides plugin selection, registration, configuration, and cleanup, with examples for implementing effects and reviewing existing animation code.
