Create reusable agent skills from recurring tasks, or improve existing ones through test prompts and user feedback. Compare outputs with and without a skill, measure performance, and refine descriptions so skills are invoked for the right requests.
Guides implementation and maintenance of Claude applications using language-specific references and official SDKs, the libraries used to call the API. Covers tool integration, streaming responses, model migration, cost reviews, prompt audits, and evaluation workflows.
Create, edit, and clean spreadsheet files, convert table formats, and add formulas, formatting, or charts. The workflow includes recalculating formulas and checking errors before delivering a spreadsheet that updates when its inputs change.
Create original posters and static artwork by first defining a visual direction, then expressing it through color, shapes, spacing, and restrained text. Deliverables include PNG or PDF artwork and a Markdown document explaining the design philosophy.
Process PDF documents by extracting text, tables, and images, merging or splitting files, rotating pages, creating documents, and filling forms. It also covers password protection and OCR, which recognizes text in scanned pages to make them searchable.
Build complex interactive artifacts for claude.ai with React, Tailwind CSS, and shadcn/ui. Start from a configured project, develop interfaces with state management or navigation, and bundle the result into one shareable HTML file.
Find Claude Academy learning resources that closely match questions about using Claude, its features, or team adoption. It supplements direct answers with a small selection of relevant courses, tutorials, worked examples, or product learning hubs.
Test local web applications with Playwright, a browser automation tool. Check frontend functionality, investigate interface behavior, capture screenshots, and inspect browser logs, with a helper script that manages one or more application servers during testing.
Write internal communications using guidance matched to the document type and the company’s preferred style. It covers progress updates, newsletters, FAQ answers, leadership updates, and incident reports, with instructions for format, tone, and gathering information.
Apply Anthropic's brand colors and typography to visual materials. The skill specifies heading and body fonts, background-aware text colors, and accents for shapes, with fallback fonts when Poppins and Lora are unavailable.
Build MCP servers, connectors that let AI models use external services through tools. This skill guides API research, tool design, implementation in TypeScript or Python, testing, and evaluation with realistic questions that require multiple tool calls.
Create animated GIFs for Slack emoji and messages from uploaded images or drawn shapes. Adjust dimensions, colors, and frame rate, combine motion effects, and use included validation tools to check the finished file.
Add two or three specific follow-up questions after actionable advice, plans, estimates, or analysis. The questions help users examine facts, reasoning, and missing context before acting, with clear exclusions and a limit of once per conversation.
Provides a minimal starting file for defining a skill, with a name field and placeholders for its description and instructions. The supplied template contains no implemented task or workflow.
Creates, edits, and reads PowerPoint presentations and templates. Supports text extraction, combining or splitting decks, and working with layouts and speaker notes, with file validation and visual checks to identify clipped text, overlaps, and leftover placeholders.
Design new interfaces or reshape existing ones with colors, typography, and layouts grounded in the subject and audience. It guides planning, implementation, and critique, including interface wording, purposeful motion, mobile layouts, and accessibility.
Create and edit Word documents and templates, extract or reorganize content, and format reports with headings, tables, and images. The skill also covers tracked changes, comments, and checks of document structure and appearance.
Create original generative art with p5.js, using particles, mathematical rules, and controlled randomness. Explore variations through interactive controls, reproduce results with a seed value, and save the artwork as a PNG.
Co-write proposals, specifications, and decision documents through a guided process. Gather background, draft and refine each section, then test the document with a fresh Claude conversation to find unclear explanations and missing context.
Applies coordinated colors and fonts to slides, documents, reports, and HTML landing pages. Choose from ten preset themes using a visual showcase, or request a custom theme based on a description and review it before application.
Connect external services to Claude Code plugins through MCP, a protocol that exposes service functions as tools. Get guidance on server configuration, connection methods, authentication, tool permissions, and testing connections and tool calls.
Create or improve skills for Claude Code plugins by defining clear activation conditions, writing focused instructions, and organizing supporting files. The guidance covers reusable scripts, reference documents, examples, and testing whether a skill activates for the intended requests.
Build specialized agents for Claude Code plugins that handle tasks involving multiple steps. Define when each agent should run, its responsibilities, available tools, and expected output, then validate its configuration and test its behavior.
Make Claude Code plugin behavior configurable per project using local Markdown files. Learn to store structured settings and notes, read them from hooks or commands, and handle defaults, validation, and user-local configuration.
