What it is

Public repository for Anthropic's implementation of skills for Claude. Skills are folders containing instructions, scripts, and resources to improve task performance by loading Claude with specialized capabilities. The repository notes that each skill is self-contained in its own folder with a SKILL.md file containing instructions and metadata that Claude uses. It also mentions that many skills are open source (Apache 2.0) and that some document-related skills are source-available but not open source.

How it works

Skills are organized as folders, each with a SKILL.md file containing YAML frontmatter and instructions that Claude will follow when the skill is active. There are patterns and examples for creating skills, including a template-skill as a starting point. The repository provides guidance on creating custom skills and explains how skills can be used with Claude Code, Claude.ai, and the Claude API. Commands demonstrate how to register and install skills as plugins or via the API.

Getting started

Commands for Claude Code plugin marketplace integration: /plugin marketplace add anthropics/skills

For installing specific skill sets via Claude Code: /plugin install document-skills@anthropic-agent-skills /plugin install example-skills@anthropic-agent-skills

After installation, skills can be invoked by mentioning them in Claude Code. Examples show using a PDF skill to extract form fields from a file path.

Additional instructions point to Claude.ai and Claude API usage for accessing and uploading skills, with links to relevant guides.

docxUse this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files) or Word templates (.dotx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', '.dotx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx or .dotx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word documenDocumentationscriptspptxUse this skill any time a .pptx or .potx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx or .potx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates (.potx), layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx or .potx filename, regardContent & MarketingscriptsxlsxUse this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .xltx, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in my downloads\") — and wants something done to it or produced from it. Also trigger for cleaninData & Analyticsscriptsskill-creatorCreate new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.Testing & QAscriptspdfUse this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.AI & Agentsscriptsmcp-builderGuide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).Code Review & Qualityscripts
