The 30 Best Claude Code Skills to Add (Picked by Use Case)

Most Claude Code users discover skills by accident. Someone mentions a /skill-name command, it works brilliantly, and suddenly they want more. What most guides miss is that the best Claude Code skills depend entirely on what you actually do. A developer, a teacher, and an ops manager all have very different workflows, and the skill that saves one of them hours a week might be completely useless to the others.

This guide covers the best Claude Code skills by use case, starting with the built-in skills you already have and may not know about, then moving into the top picks for developers, teachers and students, document workers, writers, business teams, and creative professionals. All 30 skills here are real and free, and we re-checked every source repository and install command on 9 November 2026.

The Key Takeaways

• Claude Code now bundles 20 skills, including /simplify, /batch, /debug, /code-review and /claude-api, according to Anthropic’s commands reference on 9 November 2026. Most need no setup and load in every session
• Since version 2.1.3 (9 January 2026), custom slash commands and skills are one system; your existing .claude/commands/ files still work
• The quickest install is now a plugin: /plugin marketplace add anthropics/skills adds Anthropic’s official skills, and single skills still work as SKILL.md files in ~/.claude/skills/ (personal) or .claude/skills/ (project)
• obra/superpowers is the most-starred community repository on this list, with about 315,000 GitHub stars on 9 November 2026; planning-with-files had about 28,000
• Skills are free to use; you only pay for Claude Code itself, which Anthropic includes in every paid Claude plan but not in Free

What Are Claude Code Skills?

A Claude Code skill is a SKILL.md file that gives Claude a detailed playbook for a specific task. Skills live in a folder inside .claude/skills/, and you invoke them by typing /skill-name in any Claude Code session. Claude can also load them automatically when a task matches the skill’s description.

Since Claude Code v2.1.3 (9 January 2026), custom slash commands and skills have been one system. A file at .claude/commands/deploy.md and a skill at .claude/skills/deploy/SKILL.md both create /deploy, so your existing commands still work. Skills add optional features like supporting files, subagent execution, and invocation control. They also follow the open Agent Skills standard, so many of the community picks below work in other coding agents too. If you want Claude to do this kind of work outside the terminal, our Claude Cowork guide covers the desktop side.

How to install a community skill (5 steps)

1. Add Anthropic’s skills marketplace from anthropics/skills in a Claude Code session: /plugin marketplace add anthropics/skills
2. Install a bundle: /plugin install document-skills@anthropic-agent-skills for pdf, docx, xlsx and pptx, or /plugin install example-skills@anthropic-agent-skills for the creative, design and developer skills
3. For a community skill from a list like travisvn/awesome-claude-skills, use the install command in its README, or create the folder yourself: mkdir -p ~/.claude/skills/skill-name
4. Copy the skill’s folder, including its SKILL.md file, into that directory
5. Type /skill-name to invoke it, or let Claude load it automatically. Skills installed from a plugin run as /plugin-name:skill-name

Personal skills (in ~/.claude/skills/) work across every project on your machine. Project skills (in .claude/skills/ inside a repo) apply only to that codebase. Cowork and cloud sessions do not read ~/.claude/skills/ on your machine; to use a skill there, enable it for your claude.ai account.

Anthropic also runs an official plugin marketplace, claude-plugins-official, which Claude Code adds for you the first time you start an interactive terminal session. It listed 317 plugins on 9 November 2026, including superpowers, frontend-design and skill-creator from this list. Our Claude marketplace guide explains how the plugin catalogs differ.

How to vet a skill before installing it

A SKILL.md file is plain text, and Claude follows whatever instructions it contains. That means a poorly written or malicious skill could instruct Claude to take actions you did not intend. Before adding any community skill, run through this checklist.

Check the GitHub repo before installing:

• Star count and activity. A skill with hundreds of stars and recent commits is far safer than one with 3 stars posted last week. Low activity is not automatically a problem, but it is a signal worth noticing.
• Read the SKILL.md file yourself. Open the raw file and read the instructions Claude will follow. If anything looks unusual, grant access, or asks Claude to call external URLs, treat that as a red flag.
• Check open issues and pull requests. If other users have flagged problems or unexpected behaviour, those will show up here.
• Look at the author’s profile. Established developers with a history of public repos are lower risk than anonymous accounts with a single skill file.
• Check what a plugin installs. A plugin can bundle hooks and MCP servers as well as skills, so it can run commands at points in a session without you typing anything. /plugin install opens the plugin’s details before installing; read that pane first.

When installing:

• Test new skills at project level first (.claude/skills/ inside a specific repo) before promoting them to your global ~/.claude/skills/ directory. That limits any unintended effects to one project.
• Official Anthropic skills (from github.com/anthropics/skills) and widely-starred community collections are the safest starting point.

Built-In Skills You Already Have

Before installing anything, check what you already have. Claude Code bundles 20 skills, according to Anthropic’s commands reference on 9 November 2026, including /code-review, /loop and /doctor. Most are available in every session and need no setup. These four are the ones most users overlook.

1. /simplify: Clean up your code automatically

Source: Official Anthropic, bundled with Claude Code

Run /simplify after implementing a feature or fixing a bug and Claude runs four parallel review agents: reuse of existing helpers, simplification, efficiency, and whether the change sits at the right level of abstraction. It then applies the fixes. /simplify does not look for correctness bugs; the separate /code-review skill does that. Pass a path or a PR reference to review a specific target.

Best for: Developers who want a quick cleanup pass before committing. One command replaces a full manual review cycle.

2. /batch: Make large-scale changes across your codebase

Source: Official Anthropic, bundled with Claude Code

Describe a change and /batch researches your codebase, breaks the work into 5 to 30 independent units, and presents a plan for your approval. It then spawns one background agent per unit, each in an isolated git worktree. Each agent implements its unit, runs tests, and opens a pull request or reports what happened.

Best for: Developers tackling sweeping refactors such as migrating a framework, renaming conventions across hundreds of files, or adding a new pattern consistently. Requires a git repository, or a worktree hook if you use a different version control system.

3. /debug: Troubleshoot your Claude Code session

Source: Official Anthropic, bundled with Claude Code

When a Claude Code session produces unexpected results, /debug turns on debug logging and troubleshoots the session by reading the debug log. Logging is off by default unless you started Claude Code with claude --debug, so /debug captures from the moment you run it. You can optionally describe the issue to focus the analysis.

Best for: Any user who has hit a confusing mid-session failure. Run it as soon as something looks off, and describe what went wrong to get a more targeted diagnosis.

4. /claude-api: Load the Anthropic API reference

Source: Official Anthropic (anthropics/skills/tree/main/skills/claude-api)

The /claude-api skill loads Claude API and Managed Agents reference material for your project’s language. Claude activates it automatically when your code imports anthropic or @anthropic-ai/sdk. Subcommands start specific workflows: /claude-api migrate moves existing code to a newer model, and /claude-api cost-optimize profiles where your API spend goes.

Best for: Developers building applications on top of Claude’s API. Replaces the need to keep a separate browser tab open with the API docs.

Best Claude Code Skills for Developers

These three skills cover the core phases of a typical development workflow. Each addresses a gap that writing prompts manually cannot reliably fill, and all are free to install from GitHub.

5. planning-with-files: Persistent task planning that survives context resets

Source: Community (OthmanAdi/planning-with-files)

planning-with-files implements a three-file planning system: task_plan.md for phases and progress, findings.md for research notes, and progress.md for session logs and test results. Hooks re-inject the active plan into every turn, and after /clear or a new session the skill re-reads the files from disk. The repository had about 28,000 GitHub stars on 9 November 2026. Install it as a plugin with /plugin marketplace add OthmanAdi/planning-with-files, then /plugin install planning-with-files@planning-with-files.

The pattern is the one Manus, the AI agent startup, described for its own agent. planning-with-files packages that workflow for Claude Code and more than 60 other coding agents.

Best for: Any developer working on multi-session projects. Essential for long builds, complex features, or anything that spans more than one Claude Code session.

6. webapp-testing: Automated browser tests with Playwright

Source: Official Anthropic (anthropics/skills/tree/main/skills/webapp-testing)

The webapp-testing skill tests local web applications by writing Python Playwright scripts. Claude navigates your app, simulates user interactions, captures screenshots, and reads browser logs, then reports what failed. A helper script starts your dev server first if it is not already running. Because Claude Code reads images natively, you can paste those failure screenshots straight back into a prompt, a workflow our guide on how to paste images into Claude Code covers in full.

Best for: Developers and QA engineers who want automated test coverage without writing every test manually. Particularly useful for regression testing after UI changes.

7. mcp-builder: Create Model Context Protocol servers

Source: Official Anthropic (anthropics/skills/tree/main/skills/mcp-builder)

The mcp-builder skill guides you through building a new MCP (Model Context Protocol) server, in Python with FastMCP or in TypeScript with the MCP SDK. It covers tool design and connection logic, so you can focus on the capabilities you want to expose. MCP servers let Claude connect to external data sources, APIs, and internal services.

Best for: Developers who want to extend Claude Code with custom data sources or connect it to internal APIs. This is the entry point to building your own Claude integrations without starting from a blank file.

Best Claude Code Skills for Teachers and Students

Skills are not just for developers or office workers. These six picks are built for education, from students managing heavy coursework to teachers who need to create high-quality learning materials at speed.

8. learn-faster-kit: AI study coach with spaced repetition

Source: Community (hluaguo/learn-faster-kit)

The learn-faster-kit is an AI learning coach built on the “FASTER” framework for self-teaching. It generates personalized syllabi for your skill level and goals, schedules spaced repetition reviews, and produces exercises and projects. You pick from four modes: Balanced, Exam-Prep, Theory-Focused, or Practical. It installs as a small launcher with uv, and the learn-faster command starts Claude Code in coaching mode.

Best for: Students who want a structured study plan for any subject, not just programming. Load a topic, describe your current level, and receive a customized learning track with built-in review sessions.

9. scientific-agent-skills: 177 skills for research and science

Source: Community (K-Dense-AI/scientific-agent-skills)

This collection, renamed from claude-scientific-skills, held 177 skills on 9 November 2026. They cover biology, chemistry, medicine, physics, engineering, Earth science and data analysis, from single-cell RNA-seq and variant annotation to satellite imagery and time series. Each skill follows the open Agent Skills standard, so they work with Claude Code, Cursor, Codex and other compatible tools. Install them with npx skills add K-Dense-AI/scientific-agent-skills. If you are weighing Cursor as your editor, our Cursor pricing 2026 guide breaks down every plan.

Best for: Researchers, science students, and academics who work with complex data or need domain-specific analysis workflows. Rather than prompting from scratch, you invoke a purpose-built skill for your exact field.

10. fluent: Language learning inside your working environment

Source: Community (m98/fluent)

The fluent plugin turns Claude Code into an interactive language tutor. It adapts to your level, explains grammar when you ask, schedules reviews with spaced repetition, and tracks every answer and mistake across sessions. All data stays on your machine. Install it with claude plugin marketplace add m98/fluent && claude plugin install fluent@m98, then run /fluent-setup.

Best for: Students learning a second language who spend significant time in the terminal or code editor. Building a language habit becomes much easier when the tool is already open in front of you.

11. doc-coauthoring: Collaborative writing with structured feedback

Source: Official Anthropic (anthropics/skills/tree/main/skills/doc-coauthoring)

The doc-coauthoring skill walks you through writing a document in three stages: context gathering, refinement and structure, and reader testing. Claude asks clarifying questions, drafts and refines the document section by section, then tests the draft with a fresh sub-agent to find what a new reader would miss. Students can use it for essays and reports; teachers can use it for course materials and proposals.

Best for: Students working on essays or research papers who want structured AI feedback rather than a full rewrite. Also excellent for teachers who want to develop or update course materials with a consistent revision process.

12. dmccreary/ibook-skills: 14 skills for building interactive textbooks

Source: Community (dmccreary/ibook-skills)

This collection, renamed from dmccreary/claude-skills, lists 14 active skills for building intelligent textbooks with MkDocs. They cover learning graph generation, chapter content, p5.js simulations (MicroSims), glossaries, FAQs, references, and a quiz generator that writes Bloom’s Taxonomy-aligned questions. Several are meta-skills that route to further sub-workflows. The content is licensed CC BY-NC-SA 4.0, so check the terms before commercial use.

Best for: Teachers building a full course site, chapter by chapter, with quizzes and interactive simulations built in.

13. tutor-skills: Transform any document into a study vault

Source: Community (bevibing/tutor-skills)

The tutor-skills collection provides two skills that work together. /tutor-setup converts PDFs, markdown, HTML, EPUB files and source code into structured Obsidian vaults with interlinked notes and practice questions. /tutor then runs an adaptive quiz that tracks understanding at the concept level, in four-question rounds, and marks weak areas for targeted drills.

Best for: Students who learn by active recall. Instead of re-reading notes passively, you work through a structured vault that tests your understanding at each step and adapts based on what you get wrong.

Best Claude Code Skills for Document and Office Work

These four skills handle the most common office formats directly from your Claude Code session. All four live in Anthropic’s official repository, install together as the document-skills plugin, and produce real files you can open immediately.

14. pdf: Analyse, extract, and summarise documents

Source: Official Anthropic (anthropics/skills/tree/main/skills/pdf)

The pdf skill handles comprehensive document processing, including text and table extraction, summarisation, merging, splitting, and form handling. It works on research papers, contracts, reports, and any multi-page document you need to extract meaning from quickly.

Best for: Anyone who regularly processes long documents. Upload a 200-page report and ask Claude to pull the five most important findings, or extract all the payment terms from a contract.

15. docx: Create and edit Word documents

Source: Official Anthropic (anthropics/skills/tree/main/skills/docx)

The docx skill lets you create, edit, and analyse Microsoft Word documents without opening Word. You can draft from a brief, reformat existing content, restructure headings, and export a clean .docx file. It handles styles, tables, and multi-section documents.

Best for: Anyone who produces Word documents regularly and wants to cut the back-and-forth of copy-pasting between Claude chat and Word.

16. xlsx: Excel spreadsheets without Excel expertise

Source: Official Anthropic (anthropics/skills/tree/main/skills/xlsx)

The xlsx skill creates, edits, and analyses Excel spreadsheets. Describe the data structure you need and it generates the file, writes formulas, cleans inconsistent data, and adds charts. Non-Excel users get clean, working spreadsheets without needing to know syntax.

Best for: Anyone who needs to build a working spreadsheet from scratch or clean up messy data. Particularly useful for reporting workflows where the same format is produced on a recurring basis.

17. pptx: Create presentation decks from scratch

Source: Official Anthropic (anthropics/skills/tree/main/skills/pptx)

The pptx skill builds PowerPoint presentations from a brief, a set of bullet points, or a topic you describe. It structures the narrative, lays out slides logically, and exports a .pptx file ready to open in PowerPoint or present directly. You keep creative control while Claude handles the structure and flow.

Best for: Anyone who produces presentations regularly and wants to get from a brief to a structured deck without spending hours in slide mode.

Need the file without the terminal?

If you want the finished document rather than a Claude Code workflow, ask for it in a chat window. Drop a PDF into Fello AI and get the answer, or ask for a Word document, an Excel sheet or a PowerPoint deck and get the file, on Mac, iPhone and iPad. There is no skill to install and no terminal to open, and you can switch between Claude, GPT, Gemini and other models in the same app.

Best Claude Code Skills for Writers and Content Creators

Skills are not only for people who write code. These five picks work for anyone dealing with content, brand standards, and communications, and none requires technical setup beyond installing the skill file.

18. claude-seo: Full-site SEO audit for any website

Source: Community (AgriciDaniel/claude-seo)

The claude-seo plugin runs SEO audits from inside Claude Code. On 9 November 2026 it bundled 26 sub-skills and 19 specialist agents covering technical SEO, E-E-A-T content quality, schema markup, and AI search visibility in Google AI Overviews, ChatGPT and Perplexity. Run /seo audit <url> for a full-site audit or /seo page <url> for a single page. Install it with /plugin marketplace add AgriciDaniel/claude-seo, then /plugin install claude-seo@agricidaniel-claude-seo and /seo setup.

Best for: Content writers, SEO specialists, and marketers who want a fast and thorough first pass on optimisation before publishing. To pick a model for the writing itself, the best AI models comparison ranks the current options.

19. brand-guidelines: Anthropic’s brand kit, and a template for yours

Source: Official Anthropic (anthropics/skills/tree/main/skills/brand-guidelines)

The brand-guidelines skill applies Anthropic’s own brand colours and typography to anything Claude produces: a dark and light palette, an orange accent, Poppins headings and Lora body text. Out of the box it styles content in Anthropic’s look, not yours. Its real value is as a template: copy the skill, swap in your own hex codes, fonts and tone rules, and Claude applies your brand the same way.

Best for: Writers and designers at companies with strict brand standards who are willing to adapt the skill. Agencies can keep one copy per client brand.

20. canvas-design: Visual assets in PNG and PDF formats

Source: Official Anthropic (anthropics/skills/tree/main/skills/canvas-design)

The canvas-design skill first writes a short design philosophy, then expresses it as a poster, artwork or other static design in PNG or PDF format. You describe what you need, provide colour and style constraints, and receive finished visuals without opening a design tool.

Best for: Content creators who need graphics for social posts, blog headers, or quick promotional assets. Not a replacement for full design software, but fast and practical for routine visual work.

21. internal-comms: Status reports, newsletters, and FAQs

Source: Official Anthropic (anthropics/skills/tree/main/skills/internal-comms)

The internal-comms skill generates structured internal communications, including status reports, team newsletters, FAQs, and policy updates. You provide the raw information and it produces formatted, professional documents ready to share with your team.

Best for: Writers and communications professionals who produce high volumes of internal content. The skill handles the formatting and structure so you can focus on the information rather than the presentation.

22. slack-gif-creator: Animated GIFs sized for Slack

Source: Official Anthropic (anthropics/skills/tree/main/skills/slack-gif-creator)

The slack-gif-creator skill builds animated GIFs to Slack’s constraints: 128x128 pixels for emoji GIFs and 480x480 for message GIFs, with limited colours and short durations to keep files small. Describe the animation you want and it produces a file ready to drop into a conversation. Works for reactions, announcements, and team celebrations.

Best for: Community managers, marketing teams, and anyone who uses custom GIFs to build team culture or drive engagement in messaging apps.

Best Claude Code Skills for Business and Operations

These four skills are built for knowledge work that has nothing to do with writing code. If your day involves meetings, spreadsheets, budget decisions, or building internal tools, all four will save you significant time each week.

23. meeting-insights-analyzer: Find patterns in how you communicate in meetings

Source: Community (ComposioHQ/awesome-claude-skills/meeting-insights-analyzer)

This skill analyses meeting transcripts for communication patterns: speaking ratios and turn-taking, conflict avoidance, filler words and hedging, and how often you listen versus talk. It scans a folder for transcripts in .txt, .md, .vtt, .srt, or .docx format and returns specific examples with feedback. It is built as a communication coach, so use it to improve how you run meetings.

Best for: Team leads and managers who want concrete feedback on their own meeting habits. Particularly useful for tracking improvement across many meetings over time.

24. lead-research-assistant: Identify and qualify high-quality leads

Source: Community (ComposioHQ/awesome-claude-skills/lead-research-assistant)

The lead-research-assistant skill finds and qualifies leads by analysing your product or service against your ideal customer profile. It researches target companies, gives each one a fit score from 1 to 10, and suggests an outreach strategy for each. Everything runs in your Claude Code session.

Best for: Sales teams, growth managers, and founders who need fast, targeted prospect research without paying for dedicated lead intelligence platforms.

25. obra/superpowers: A full development method in 15 skills

Source: Community (obra/superpowers)

The superpowers library by Jesse Vincent (obra on GitHub) is a complete development methodology built from 15 composable skills, counted on 9 November 2026. They cover test-driven development, systematic debugging, brainstorming, writing and executing plans, code review, git worktrees, and subagent-driven development. Instead of jumping into code, Claude first asks what you are trying to build, writes a spec, then a plan, then works through it with subagents. Install it from Anthropic’s official marketplace with /plugin install superpowers@claude-plugins-official.

Best for: Technical leads and senior developers who want a complete Claude Code methodology rather than a single skill. Superpowers treats Claude Code as a serious development partner with structured, repeatable workflows for every phase of a project.

26. frontend-design: Production-grade UI instead of generic components

Source: Official Anthropic (anthropics/skills/tree/main/skills/frontend-design)

The frontend-design skill makes Claude plan the design before writing code. It drafts a compact system of 4 to 6 named colours, typefaces, and a layout concept, checks that plan against your brief, and revises anything that reads like a generic default. Only then does it build. The skill names the tells of AI-generated pages, such as identical rounded cards and an all-caps label above every heading, and steers away from them. It is also a plugin in Anthropic’s official marketplace.

Best for: Developers and non-technical ops teams building internal tools who want something that looks designed rather than assembled. If you are tired of AI-generated UIs that all look identical, this skill changes the output significantly.

Best Claude Code Skills for Creative Work

These three skills are for users who want Claude to produce visual art, generative design, and interactive web content. Each one produces actual output files rather than just instructions or code snippets.

27. algorithmic-art: Generative art with p5.js

Source: Official Anthropic (anthropics/skills/tree/main/skills/algorithmic-art)

The algorithmic-art skill generates artwork with p5.js using seeded randomness, so every piece is reproducible and tweakable. You describe a concept, a colour palette and a style, and the skill writes a short algorithmic philosophy, then a working sketch with an interactive HTML viewer for exploring its parameters.

Best for: Creative coders, generative artists, and designers who want to explore algorithmic aesthetics without writing all the code by hand. Every output is a starting point you can iterate on.

28. theme-factory: Ready-made themes for decks, docs and pages

Source: Official Anthropic (anthropics/skills/tree/main/skills/theme-factory)

The theme-factory skill applies a consistent theme to slides, documents, reports and HTML pages. It ships 10 preset themes, each a colour palette with hex codes plus a font pairing, and shows them in a showcase PDF so you can pick one. It can also generate a new theme on the fly.

Best for: Anyone who wants decks and documents to look consistent without choosing colours and fonts from scratch every time.

29. web-artifacts-builder: Complex interactive HTML with React and Tailwind

Source: Official Anthropic (anthropics/skills/tree/main/skills/web-artifacts-builder)

The web-artifacts-builder skill builds complex, interactive HTML artifacts with React, Tailwind CSS and shadcn/ui components. It handles multi-component layouts, state and routing, then bundles everything into a single self-contained HTML file you can open in a browser or share as a claude.ai artifact.

Best for: Creative technologists, developers building demos, and anyone who wants a polished interactive prototype without scaffolding an entire project. Also useful for teachers building interactive STEM exercises.

Build Your Own Claude Code Skill

Once you have worked through the list above, the most powerful move you can make is building a skill for a workflow specific to you. The skill-creator makes that straightforward, even if you have never written a SKILL.md file before.

30. skill-creator: A skill that builds skills

Source: Official Anthropic (anthropics/skills/tree/main/skills/skill-creator)

The skill-creator skill helps you build a new skill or improve an existing one. It interviews you about what to automate and when the skill should trigger, drafts the SKILL.md file, then runs test prompts with and without the skill so you can compare the results. It can also benchmark a skill and tune its description so Claude loads it at the right moments. It is also a plugin in Anthropic’s official marketplace.

Best for: Anyone who has a repetitive task that none of the existing skills cover. After one session with skill-creator, you will have a custom skill tailored to your exact workflow. This is the highest-leverage skill on the list because it multiplies the value of everything else. For a step-by-step walkthrough, see our guide to creating your own Claude Code skills.

Where to Find More Claude Code Skills

The two best starting points are the official Anthropic skills repository at github.com/anthropics/skills and the community-curated list at travisvn/awesome-claude-skills, which organises contributions by category (its last update was in April 2026). For a broader view including hooks, plugins, and agent orchestrators, hesreallyhim/awesome-claude-code is worth bookmarking. Inside Claude Code, run /plugin and open the Discover tab to browse every marketplace you have added.

For setup help, see the guide to setting up the Claude Desktop app.

Conclusion

The best Claude Code skill is the one that removes friction from a task you do repeatedly. Start with the bundled skills; /simplify and /batch are already installed and most users never touch them. Add planning-with-files if you do any multi-session development work, learn-faster-kit if you want to accelerate how you study, or meeting-insights-analyzer if you want sharper meetings. Pick two or three from your use case category, then build your own with skill-creator once you spot a gap nothing else fills.
