Develop Spring Boot features and fixes by writing tests before implementation. Guides unit, web, persistence, and integration testing with JUnit 5, Mockito, MockMvc, and Testcontainers, plus JaCoCo measurement of how much code tests cover.
Create and edit videos using a measured reference style for color and cutting rhythm. Combine generated clips, existing footage, overlays, and 3D props, then check visual measurements and deliver both a video and an editable timeline.
Audit repository settings, connected tools, and the agent's runtime setup to show what is usable now. Identify missing workflows and integrations, then recommend prioritized ECC skills, automation hooks, agents, or tool connections.
Save project context and task handoffs as local Markdown documents that Claude, Codex, and other agents can share. The skill guides searching prior knowledge, recording evidence and remaining work, and checking the shared memory vault for structural problems.
Choose how detailed an answer should be before it is written, using four levels and estimated token counts, a measure of text length. The skill then adjusts the response and keeps the chosen level for subsequent replies.
Use the VideoDB Python SDK to search video by speech or visual content and create playable clips with timestamps. Add subtitles and audio, change aspect ratios, and configure alerts for live video or desktop sessions.
Deploy and manage services across an Uncloud cluster using the uc command line. Covers public ports, Caddy routing for incoming traffic, service scaling, log inspection, and management of machines and storage volumes.
Edit existing footage into vlogs, tutorials, demos, or short social clips. This skill guides segment selection, cutting, overlays, audio additions, and platform-specific framing, with final pacing and polish handled in a traditional video editor.
Build end-to-end tests that operate Windows desktop apps through pywinauto and Windows UI Automation, an interface for accessing screen controls. Covers stable element selection, waits, failure screenshots, test isolation, and CI setup for native applications.
Design and review REST APIs with consistent URLs, HTTP status codes, error responses, and pagination, which divides results into smaller batches. Covers authentication, access limits, and versioning to help define clear behavior for API users.
Build or review Vue.js 3 and Nuxt interfaces using practical patterns for components, shared state, navigation, and tests. Learn how to organize code and manage reactivity, the mechanism that updates the interface when data changes.
Plan a consistent visual direction for music videos and short edits in angelcore, cloud-trance, and hyperpop styles. Define color, lighting, camera movement, and beat-synced cuts, then coordinate footage generation and editing through companion skills.
Find existing skills before building a new one. Search local installations, marketplaces, GitHub, and the web, then review candidates for relevance and risky behavior to help choose between reuse, extension, and fresh creation.
Review Claude skills and commands for usefulness, overlapping content, and outdated technical references. Choose a scan of changed skills or a full review, then receive reasoned recommendations to keep, improve, update, retire, or merge them.
Build and review SwiftUI interfaces for iOS and macOS with guidance on state management, reusable views, navigation, and rendering performance. Examples show how to organize data flow and reduce unnecessary screen updates.
Turn notes, transcripts, or research into polished articles, guides, tutorials, and newsletters. Use supplied writing examples or brand guidance to maintain a consistent voice, organize a clear argument, and support factual claims with provided evidence.
Run repository commands, inspect Git state, investigate CI or build failures, and verify focused fixes. Report the commands and results as evidence, clearly distinguishing local changes, local verification, commits, and pushes.
Build or review Java Spring Boot backends using examples for web APIs, separate application layers, and database access. Covers input validation, error handling, caching, background processing, and logging to guide maintainable implementations.
Build and review server-side APIs with Node.js, Express, and Next.js. The skill provides patterns for separating responsibilities, reducing database queries, caching results, checking access permissions, and handling background work and errors.
Build Java applications with tinystruct, including actions usable from both a terminal and the web. Get guidance on launcher generation, routing, JSON responses, database storage, tests, and MCP tools that agents can call.
Design local data storage in Swift using actors, which control concurrent access to shared data. Combine an in-memory cache with JSON file storage, implement save and lookup operations, and connect the repository to an observable ViewModel.
Browse available specialist agents by domain, select up to five, and run them independently on the same task in parallel. Receive a combined report showing each agent’s findings, shared conclusions, conflicting recommendations, and suggested next steps.
Translate visa document images into English using OCR, which reads text from images. Create a bilingual PDF with the original image and a formatted translation on separate pages, preserving names, numbers, dates, and amounts.
Audit and improve a website’s search visibility by fixing technical issues, refining page titles and headings, adding structured data that describes content to search engines, and planning keywords and internal links.
