Review first review before installing

Open the source and read safety notes before installing.

Safety notes

  • The repository is explicitly presented as demonstration and educational material; behavior available in Claude products can differ from repository examples.
  • Document skills can read, transform, and create files such as PDFs, Word documents, PowerPoint decks, and spreadsheets, so review generated artifacts before sharing or publishing them.
  • The MCP builder skill guides agents through creating MCP servers and evaluations; generated servers still need security review, least-privilege tool design, authentication review, and transport testing.
  • The skill creator workflow can generate instructions, scripts, references, and assets; review all generated resources before installing them into an agent host.

Privacy notes

  • Skill usage can expose documents, spreadsheets, slide decks, prompts, company workflows, brand guidelines, MCP designs, API details, and generated artifacts to Claude or the configured model/runtime.
  • Do not upload or commit customer documents, regulated data, private brand assets, secrets, credentials, or unreleased business plans unless the environment and account policy allow that data.
  • When creating custom skills, check bundled scripts, references, and assets for private data before sharing a repository, plugin, or ZIP archive.

Prerequisites

  • Claude Code for plugin marketplace installation, Claude.ai paid plan access for built-in/example skill usage, or Claude API access for programmatic skill creation.
  • A target task where a demonstration skill, document skill, MCP builder workflow, skill creator workflow, or custom skill template is appropriate.
  • Review of the repository disclaimer and license/source-availability notes before relying on a skill in production.
  • Local testing for any copied or customized skill before using it on sensitive documents, production workflows, or customer data.

About this resource

Anthropic Agent Skills

anthropics/skills is Anthropic's public repository for Claude skills. It contains example skills, document skills, an Agent Skills specification pointer, a minimal template skill, and Claude Code plugin marketplace instructions.

Use this listing for Anthropic's own public skills repository and reference materials. Use narrower entries when evaluating a single community skill, third-party skill pack, MCP server, or tool.

Knowledge Freshness

Claude Code plugin behavior, Claude.ai skill availability, Claude API skill endpoints, and the Agent Skills specification can change. Verify current Anthropic support docs, Claude API docs, and the live https://agentskills.io/specification page before building production automation around repository examples.

The repository README says these skills demonstrate patterns and possibilities, and that implementations or behaviors in Claude products may differ. Treat the repository as a source-backed reference, not a guarantee that every listed skill is available or identical in every Claude surface.

Retrieval Sources

This listing is grounded in:

  • The upstream anthropics/skills README.
  • Representative SKILL.md files for mcp-builder and skill-creator.
  • The template SKILL.md for the minimal required skill structure.
  • The repository spec pointer to the Agent Skills specification.
  • Current GitHub repository metadata.

Core Workflow

Register the repository as a Claude Code plugin marketplace:

/plugin marketplace add anthropics/skills

Install a plugin from that marketplace:

/plugin install document-skills@anthropic-agent-skills
/plugin install example-skills@anthropic-agent-skills

After installation, invoke a skill by task. For example:

Use the PDF skill to extract the form fields from path/to/file.pdf.

Claude.ai users can use built-in/example skills where available on paid plans, and Claude API users can use pre-built or custom skills through Anthropic's Skills API workflow.

Capability Scope

The README organizes the repository into:

Area Scope
skills/ Creative and design examples, development and technical examples, enterprise and communication examples, and document skills
spec/ Pointer to the Agent Skills specification
template/ Minimal starter SKILL.md structure

Skill examples include document formats such as docx, pdf, pptx, and xlsx, plus development-oriented examples such as mcp-builder, skill-creator, webapp-testing, and claude-api.

The README states that many skills are open source under Apache 2.0, while the document creation and editing skills under docx, pdf, pptx, and xlsx are source-available references rather than open source.

Production Rules

  • Treat this repository as a reference and demo collection unless a specific Claude surface documents production support for the exact skill.
  • Test skills thoroughly in your own environment before relying on them for critical workflows.
  • Review document outputs, generated files, and transformed data before sharing or publishing.
  • Review generated MCP servers for authentication, tool permissions, transport choices, error handling, and evaluation coverage before deployment.
  • Do not copy example skills into internal plugins without checking license, source-availability, data-handling, and security requirements.
  • Keep customer documents, secrets, regulated data, and proprietary workflows out of public examples, issues, screenshots, and committed custom skills.

Use Cases

  • Install Anthropic's document skills in Claude Code for PDF, DOCX, PPTX, or XLSX workflows where available.
  • Use mcp-builder as a reference workflow for planning, implementing, and evaluating a high-quality MCP server.
  • Use skill-creator to understand the structure, iteration loop, and testing approach for custom skills.
  • Browse the template skill when creating a minimal SKILL.md.
  • Use the repository to learn how Claude skills package instructions, scripts, references, and assets.

Source Review

Verified on 2026-06-18:

  • The README describes skills as folders of instructions, scripts, and resources that Claude loads dynamically for specialized tasks.
  • The README says the repository contains Anthropic's implementation of skills for Claude and points the Agent Skills standard to agentskills.io.
  • The README documents Claude Code plugin marketplace installation with /plugin marketplace add anthropics/skills and direct installs for document-skills and example-skills.
  • The README describes Claude.ai paid-plan usage and Claude API skill creation through Anthropic docs.
  • The mcp-builder skill describes MCP server design, tool naming, context management, SDK choices, testing with MCP Inspector, and evaluation creation.
  • The skill-creator skill describes drafting, testing, evaluating, and iterating custom skills with SKILL.md, scripts, references, and assets.
  • The template skill shows the minimal name and description frontmatter.
  • The repository README distinguishes open-source example skills from source-available document skills.

Safety notesThe repository is explicitly presented as demonstration and educational material; behavior available in Claude products can differ from repository examples. Document skills can read, transform, and create files such as PDFs, Word documents, PowerPoint decks, and spreadsheets, so review generated artifacts before sharing or publishing them. The MCP builder skill guides agents through creating MCP servers and evaluations; generated servers still need security review, least-privilege tool design, authentication review, and transport testing. The skill creator workflow can generate instructions, scripts, references, and assets; review all generated resources before installing them into an agent host.Google Cloud skills can create, update, delete, deploy, query, or configure cloud resources, datasets, IAM policies, service accounts, APIs, containers, jobs, and networking. The gcloud skill requires command validation and safety guardrails before invoking Google Cloud CLI commands; do not let agents improvise cloud commands from memory. Skill Registry guidance includes skill lifecycle management such as upload, update, and permanent delete operations; validate environment and approval before use. Cloud Run, GKE, BigQuery, Firebase, Cloud SQL, AlloyDB, and Gemini API workflows can create cost, expose endpoints, alter data, or change production behavior. The repository notes active development, so verify exact commands, product names, API availability, and launch-stage limits before production use.This skill guides agents through MCP server work that can expose tools, resources, prompts, widgets, middleware, auth flows, and remote deployment surfaces. MCP tools can call external APIs, read or mutate local data, proxy other MCP servers, or trigger side effects depending on implementation. Widget and MCP Apps work can render user-provided data in interactive UI surfaces; validate data and avoid trusting client-side state. Authentication examples may involve OAuth, Supabase, Clerk, Auth0, WorkOS, Keycloak, custom auth, API keys, and session handling. Keep secrets in environment variables. Deployment guidance can make a server reachable by external clients; review tool authority, CORS, auth, logging, rate limits, and observability before publishing.Dart skills can modify source code, tests, pubspec dependencies, analysis options, generated mocks, coverage output, native hooks, FFI bindings, and package constraints. `dart fix --apply`, formatter runs, mock generation, build_runner, ffigen, and Native Assets hooks can create broad mechanical diffs; inspect changes before committing. Native Assets and FFI workflows may compile C/C++ code, run local toolchains, download precompiled binaries, and link dynamic or static libraries. Downloaded binaries should use cryptographic hash validation and offline fallbacks as the skill describes. Package conflict fixes can upgrade or downgrade dependencies and affect transitive package behavior across Dart and Flutter projects.
Privacy notesSkill usage can expose documents, spreadsheets, slide decks, prompts, company workflows, brand guidelines, MCP designs, API details, and generated artifacts to Claude or the configured model/runtime. Do not upload or commit customer documents, regulated data, private brand assets, secrets, credentials, or unreleased business plans unless the environment and account policy allow that data. When creating custom skills, check bundled scripts, references, and assets for private data before sharing a repository, plugin, or ZIP archive.Google Cloud workflows may expose project IDs, service account emails, OAuth tokens, API keys, ADC credentials, Terraform state, dataset names, table schemas, query text, logs, traces, prompts, model outputs, embeddings, and customer data. BigQuery, Firebase, Cloud SQL, AlloyDB, GKE, and Agent Platform workflows may process regulated or proprietary data; review data residency, IAM, retention, audit logging, and sharing rules before use. Gemini API and Agent Platform skills can send prompts, files, images, audio, video, tool inputs, structured outputs, cached contexts, and batch datasets to Google services. Keep credentials, project IDs when sensitive, private queries, logs, trace payloads, Terraform state, customer data, and generated datasets out of public prompts, issues, PRs, and screenshots.MCP Apps and servers may process prompts, tool arguments, API responses, user identity, OAuth scopes, logs, widget props, resources, and generated UI state. The skill's reference files can lead agents to inspect local source, configs, package metadata, auth providers, deployment logs, and connected MCP server definitions. Do not paste API keys, OAuth secrets, cookies, session tokens, production customer data, or private server URLs into prompts, examples, generated docs, issues, or PRs. When using hosted deployment or inspector tools, review the retention policies for mcp-use, Manufact, MCP clients, model providers, and connected services.Dart projects may contain private package names, API schemas, service URLs, test fixtures, generated mocks, coverage paths, stack traces, native library names, and build logs. Runtime-error workflows can expose stack traces, local paths, active app state, logs, and user-input data from the running program. FFI and Native Assets workflows may include proprietary C/C++ source, platform-specific build settings, binary hashes, and downloaded artifact URLs. Keep credentials, private package registries, source paths when sensitive, proprietary native code, test data, and generated coverage reports out of public prompts, issues, PRs, and examples.
