Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot and other agents read this format. **Where do the skills come from?** Public GitHub repos from vendor teams and the community, found through GitHub search and public skill directories. We list 90,454 skills from 6,521 repos. Each one links to its source. We list a skill when its license is an open license such as MIT, Apache-2.0 or CC-BY. We store its name and the one-line description from its own frontmatter, not the skill itself. **What does the free scan show?** How many skills match your project, the size of your curated list, and two picks with install commands. The counts come from the live database for your exact tags. **What do I get for $9?** The full curated list for that scan: up to 30 picks ranked for your stack and tasks, each with an install command, a one-line reason, and notes where two picks overlap or clash. One payment, no subscription. Polar handles checkout. **Do you see my code?** With a repo URL, we read the file list and a few manifest files such as package.json through the public GitHub API, and store none of it. With the CLI or the MCP tool, your code stays on your machine: they send tag names such as "nextjs" or "testing" and nothing more. **Can I pay to get my skill listed or ranked higher?** No. Placement is not for sale. Rank comes from how well a skill fits the project tags. To suggest a public skill with an open license, email us the repo link. --- ## Guides | SkillsPicker URL: https://skillspicker.com/guides/ ### Guides Each guide quotes its sources and the date we checked them. - AGENTS.md vs SKILL.md: what goes where, and how Claude Code, Codex, Copilot and Cursor read each (2026) AGENTS.md holds project instructions an agent reads at the start of every task.

The agent reads it at the start of a task, every task. Put build commands, test commands, code style and repo layout there. SKILL.md is one playbook for one job, such as a release or a database migration. The agent sees its name and description at start and reads the rest when the job comes up. One repo can have one AGENTS.md (or a few nested ones) and many skills. Facts below come from agents.md , the Agent Skills spec , and the docs for Codex , Claude Code , GitHub Copilot and Cursor , read on October 28, 2026. Want skill picks for your own repo? Scan your repo free . Paste your GitHub repo URL. You see the match count and 2 picks. The full list is $9 once , up to 30 ranked picks for that scan. #### The difference in one table | AGENTS.md | SKILL.md What it is | One Markdown file of project instructions | A folder with SKILL.md , plus optional scripts/ , references/ , assets/ Where it lives | Repo root, plus nested files in subfolders | A skill folder, such as .agents/skills// or .claude/skills// Front matter | None. Plain Markdown, any headings | YAML with name and description (both required) When it loads | At the start of each task or session | Name and description at start. The body loads when the task matches or you call it Context cost | The whole file, on every task | About 100 tokens per skill until it loads, per the spec Scope | Everything under its folder. The nearest file wins | One task Can bundle files | No | Yes: scripts, templates, reference docs Spec | agents.md , stewarded by the Agentic AI Foundation under the Linux Foundation | agentskills.io #### What AGENTS.md is The agents.md site calls it "a README for agents". It is plain Markdown with no required fields. The site lists these common sections: - Project overview - Build and test commands - Code style guidelines - Testing instructions - Security considerations Commit message rules, PR rules and deploy notes belong here. The site puts it this way: anything you'd tell a new teammate. In a monorepo, put an AGENTS.md in each package. Per the agents.md FAQ, the closest file to the edited file wins, and a prompt you type in chat overrides all of them. The site says the main OpenAI repo had 88 AGENTS.md files at the time of writing. A real example: apache/airflow ships an AGENTS.md with sections for environment setup, commands, repository structure, architecture boundaries, security model, coding standards, testing standards, and commits and PRs. #### What SKILL.md is A skill is a folder with a SKILL.md file at its top level. The file opens with YAML front matter. name (lowercase, hyphens, up to 64 characters, matches the folder name) and description (up to 1024 characters, says what the skill does and when to use it) are required. The body holds the steps. The spec describes three load stages: - Metadata (about 100 tokens): name and description load at start for every skill. - Instructions (under 5000 tokens recommended): the SKILL.md body loads when the skill activates. - Resources: files in scripts/ , references/ and assets/ load when the task needs them. That is the key gap between the two files. A 300-line AGENTS.md costs 300 lines on every task. Ten skills of 300 lines each cost ten short descriptions until one of them is needed. For every field, see our SKILL.md format guide . #### What goes where Content | Put it in | Why pnpm install , pnpm test , lint command | AGENTS.md | Needed on most tasks Code style: strict TypeScript, quote style, naming | AGENTS.md | Applies to every edit Repo layout: where handlers, tests, docs live | AGENTS.md | Saves the agent a search each time "Do not edit dist/ " or "ask before new dependencies" | AGENTS.md | A standing rule, not a task Release steps: changelog, version bump, tag, publish | SKILL.md | Many steps, used once in a while Database migration routine with a check script | SKILL.md | Needs a bundled script PDF or spreadsheet work with a template | SKILL.md | Needs bundled assets A routine you want in more than one repo | SKILL.md in your home skills folder | Skills install per user. AGENTS.md belongs to one repo The Claude Code docs give the same test for CLAUDE.md : keep it to facts Claude should hold in every session, and if an entry "is a multi-step procedure or only matters for one part of the codebase, move it to a skill or a path-scoped rule". A good pattern: keep AGENTS.md short and add one line that names your skills, for example "Release steps live in the release skill." The agent knows the skill exists without the steps in context. #### How each agent reads AGENTS.md ##### Codex Codex reads AGENTS.md before any work. Per the Codex docs : - Global: ~/.codex/AGENTS.md , or ~/.codex/AGENTS.override.md if it exists. - Project: Codex walks from the repo root down to your current folder. In each folder it takes AGENTS.override.md , then AGENTS.md , then any names in project_doc_fallback_filenames . One file per folder. - Merge: files join from root down. Files closer to your folder come later, so they win. - Cap: Codex stops at project_doc_max_bytes , 32 KiB by default. Raise it in ~/.codex/config.toml or split the file into nested ones. For Codex code review on GitHub, add a ## Code Review Rules section to the AGENTS.md nearest the code. Codex skills live in .agents/skills/ . See our Codex skills guide . ##### Claude Code Claude Code's own file is CLAUDE.md . Per the memory docs , Claude Code v2.1.277 and later reads AGENTS.md as project instructions, with one catch: Your repo has | Claude reads AGENTS.md and no CLAUDE.md or CLAUDE.local.md in your folder or above | AGENTS.md AGENTS.md and a CLAUDE.md or CLAUDE.local.md | CLAUDE.md files, not AGENTS.md A CLAUDE.md that imports @AGENTS.md | Both, through the import To read both files, open /config and set Project instructions to claude-md-and-agents-md . Claude Code does not read AGENTS.override.md , AGENTS.local.md , or anything under a .agents/ folder as instructions. The setup that works on every version is a CLAUDE.md next to AGENTS.md that holds the import plus any Claude-specific lines: @AGENTS.md ## Claude Code Use plan mode for changes under `src/billing/`. The docs say to keep each CLAUDE.md under 200 lines. Claude Code skills live in .claude/skills/ and ~/.claude/skills/ . See how to install Claude Code skills . ##### GitHub Copilot Per the Copilot docs , Copilot on GitHub reads three kinds of instructions: - .github/copilot-instructions.md for the whole repo. - .github/instructions/NAME.instructions.md files with an applyTo glob for matching paths. - AGENTS.md files anywhere in the repo. The nearest one takes precedence. A single CLAUDE.md or GEMINI.md at the root works in place of AGENTS.md . Copilot reads skills from .github/skills/ , .claude/skills/ or .agents/skills/ in the repo, and from ~/.copilot/skills/ or ~/.agents/skills/ for your user, per the Copilot skills page . For code review, Copilot reads instructions and skills from the PR's head branch, so you can test a change to either in the same PR. ##### Cursor The Cursor rules docs list AGENTS.md as the plain Markdown option, with nested files for subfolders such as frontend/AGENTS.md . Per the Cursor skills docs , Cursor skills live in .agents/skills/ or .cursor/skills/ , and Cursor loads .claude/skills/ and .codex/skills/ on top of those. For rules vs skills in Cursor, see Cursor rules vs agent skills . ##### Gemini CLI The agents.md FAQ shows how to point Gemini CLI at AGENTS.md in .gemini/settings.json : { "context": { "fileName": "AGENTS.md" } } For Gemini skills, see Gemini CLI skills . #### One repo that works in all four agents your-repo/ ├── AGENTS.md # build, test, style, layout (Codex, Copilot, Cursor, Claude Code) ├── CLAUDE.md # @AGENTS.md plus Claude-only lines ├── packages/api/AGENTS.md # API package rules, nearest file wins └── .agents/skills/ └── release/ ├── SKILL.md # name: release └── scripts/bump.sh Codex, Copilot and Cursor read .agents/skills/ . Claude Code reads .claude/skills/ . Copilot and Cursor read .claude/skills/ in addition to .agents/skills/ , so a skill there covers three of the four. The open skills CLI ( npx skills add ) writes each skill to the folder the agent expects. Its agent table lists .claude/skills/ for Claude Code and .agents/skills/ for Codex, Cursor and GitHub Copilot. To write a new skill from chat, try Anthropic's skill-creator skill. Its description says it creates, edits and measures skills. #### Common mistakes - Steps in AGENTS.md. A 40-step release runbook in AGENTS.md loads on every task, a typo fix included. Move it to a skill. - Project facts in a skill. If every task needs the test command, a skill may not load in time. Put it in AGENTS.md . - A CLAUDE.md that hides AGENTS.md. Adding any CLAUDE.md stops Claude Code from reading AGENTS.md by default. Add @AGENTS.md to it. --- ## Best Claude Code skills for Next.js: 3 free picks and how to install them (2026) URL: https://skillspicker.com/guides/best-claude-code-skills-for-nextjs/ ### Best Claude Code skills for Next.js Claude Code writes Next.js code fast, but it makes the same mistakes on many projects. It mixes the App Router and the old Pages Router in one answer. It puts hooks in Server Components, forgets the 'use client' line, and fetches data in useEffect where a server fetch fits. Caching rules changed between Next.js versions, so stale advice is common. A skill is a SKILL.md file with instructions Claude Code loads when a task matches. A good Next.js skill states the App Router rules one time, so you stop repeating them in prompts. Our database holds 196 open-license skills built for Next.js ( SkillsPicker Next.js page ). These 3 are a good start for most App Router projects. #### 3 picks to start with 1. nextjs-app-router-patterns (wshobson/agents, MIT) Covers Next.js 14+ App Router with Server Components, streaming, parallel routes and data fetching. npx skills add wshobson/agents --skill nextjs-app-router-patterns --agent claude-code 2. optimized-nextjs-typescript (Mindrally/skills, Apache-2.0) Next.js and TypeScript practices with a focus on performance, security and clean structure. npx skills add Mindrally/skills --skill optimized-nextjs-typescript --agent claude-code 3. react-patterns (giuseppe-trisciuoglio/developer-kit, MIT) React 19 patterns: Server Components, Server Actions, useOptimistic, useActionState, useTransition and Suspense. npx skills add giuseppe-trisciuoglio/developer-kit --skill react-patterns --agent claude-code The npx skills command comes from the open skills CLI . The --agent claude-code flag puts the skill where Claude Code looks for it. #### Where Claude Code loads skills Claude Code reads project skills from .claude/skills/ in your repo and personal skills from ~/.claude/skills/ in your home folder ( Claude Code skills docs ). Commit project skills so the whole team gets them. Our guide on how to install Claude Code skills covers each method. #### What to add next Three skills cover the framework. Most Next.js repos need these on top: - A testing skill for components and routes, matched to your test runner. - A review skill that checks server and client boundaries before you merge. - Skills for your stack: your ORM, your auth library, your UI kit. These differ per repo, which is why a generic top 10 list misses. For MCP servers versus skills, see Claude skills vs MCP . For React without Next.js, see React skills and our Claude Code skills for React guide . #### Get picks for your exact repo The free scan reads your repo URL or a description and shows how many skills match, plus 2 picks. The full curated list costs $9, paid one time: up to 30 picks ranked, with install commands, a reason for each and notes on overlaps ( pricing ). #### FAQ Does Next.js have an official skill for Claude Code? The 3 picks above come from open-license community repos. Check each repo's license and read the SKILL.md before you install. Do these skills work in Cursor or Codex? SKILL.md is a shared format. Change the --agent flag to cursor or codex and the CLI installs to that agent's folder. How many skills should I install? Start with 3 to 5 that match your stack. A pile of overlapping skills can give Claude Code mixed instructions. Do I need an MCP server for Next.js? Not to start. Skills hold instructions. MCP servers connect tools and data. Add an MCP server when Claude Code needs to call something outside the repo. Checked 2026-10-23. Prices and policies change.

It does not know your house rules. It may skip type hints, mix pip and uv in one answer, write tests without fixtures, or catch every exception with a bare except . You end up typing the same corrections in each prompt. A skill is a SKILL.md file with instructions Claude Code loads when a task matches. A good Python skill states your rules one time. Our database holds 220 open-license skills built for Python, and 454 match a typical Python project ( SkillsPicker Python page ). These 6 cover the basics for most repos. Each one exists on GitHub today, and we read its SKILL.md on October 23, 2026. #### 6 picks to start with 1. python-patterns ( affaan-m/ECC , MIT) Pythonic idioms, PEP 8, type hints and structure. Use it when Claude Code writes or reviews Python. npx skills add affaan-m/ECC --skill python-patterns --agent claude-code 2. python-anti-patterns ( wshobson/agents , MIT) A checklist of known bad practices. Use it before you finish a change or when a bug looks like a classic mistake. npx skills add wshobson/agents --skill python-anti-patterns --agent claude-code 3. python-testing-patterns ( wshobson/agents , MIT) pytest, fixtures, mocking and test-driven development. npx skills add wshobson/agents --skill python-testing-patterns --agent claude-code 4. python-type-safety ( wshobson/agents , MIT) Type hints, generics, protocols, and strict checks with mypy or pyright. npx skills add wshobson/agents --skill python-type-safety --agent claude-code 5. uv-package-manager ( wshobson/agents , MIT) Dependencies, virtual environments and project setup with uv.

Your framework and tools need their own: - Your web framework. See Django skills and FastAPI skills . Flask skills are in the database. - Your data stack. pandas, SQLAlchemy, or your ORM. - Your async rules, if the repo uses asyncio. These differ per repo, which is why a generic top 10 list misses. For MCP servers versus skills, see Claude skills vs MCP . To write your own, see the SKILL.md format . #### FAQ Where do I find Claude Code skills for Python on GitHub? The 6 picks above link to their GitHub folders. Our Python page lists more, each with its repo, license and install command. Do two Python review skills clash? They can. python-anti-patterns and python-code-review both review code. Start with one, and add the other if you want a second pass. Do these skills work in Cursor or Codex? SKILL.md is a shared format. Change the --agent flag to cursor or codex and the CLI installs to that agent's folder.

The --agent claude-code flag puts the skill in .claude/skills/ , where Claude Code looks for it. Swap the flag for cursor or codex to install the same SKILL.md for those agents. #### How to use it Ask Claude Code to build or restyle a page. When the task is UI work, Claude Code loads the skill on its own. Give it a direction in your prompt: the audience, the tone, a reference site. Then run a review skill such as frontend-design-review or design-critique on the result. #### Match it to your stack A design skill does not know your component library. Add a skill for it: shadcn-ui is in the table, and our Tailwind skills page lists more. For React and Next.js picks, see the React guide and the Next.js guide . #### FAQ Where does the frontend-design skill install? With --agent claude-code it lands in .claude/skills/frontend-design/ in your repo. Add -g to install it for every project in your home folder. Is the frontend design skill free? Yes.

Install Playwright in your project ( npm init playwright@latest ), since the skills call it. #### Skill or Playwright MCP A skill holds instructions: how to write tests, which locators to use, how to fix flaky runs. Playwright MCP is a server that lets the agent click and read pages through tool calls. Some skills, such as playwright-generate-test , expect the MCP server. Read the SKILL.md to see which one it needs. Our skills vs MCP guide covers the difference. #### Related guides For TDD and unit tests, see Claude Code skills for testing . For a review pass, see Claude Code skills for code review . #### FAQ How do I install the Playwright skill in Claude Code? Run the install line from the table in your repo. The CLI copies the skill to .claude/skills/ . Is there an official Playwright skill? Microsoft ships the Playwright tool and Playwright MCP. The skills above come from OpenAI, Anthropic, GitHub and LambdaTest. Do I need the Playwright CLI? Yes for most skills. The skill tells Claude Code what to run, and Playwright has to be in your project to run it. Do these skills work in Cursor or Codex? Yes. Change the --agent flag to cursor or codex . #### Sources - https://playwright.dev/docs/intro --- ## Claude Code security skills: 5 free picks for security review and scans (2026) URL: https://skillspicker.com/guides/claude-code-security-skills/ ### Claude Code security skills Short answer: pair a review skill with a scanner skill. Sentry's security-review reads your code like a reviewer. Trail of Bits' semgrep and codeql skills run real static analysis tools.

It reads the code and reports what looks unsafe. A scanner skill runs a tool such as Semgrep or CodeQL and has Claude Code explain the results. The scanner skills need that tool on your machine. Read each SKILL.md first so you know what it runs. #### Related guides For general PR review, see Claude Code skills for code review . For Python and Django projects, the Python guide lists stack picks. New to skills? Start with how to install Claude Code skills . #### FAQ Does Anthropic publish a security skill? Yes. claude-security is in Anthropic's claude-plugins-official repo, and it is in the table above. Can a skill replace a security audit? No. A skill helps Claude Code find common issues before review. High-risk code needs a paid audit or a security team. Do the Semgrep and CodeQL skills install those tools? The skill holds instructions. Install Semgrep or the CodeQL CLI on your own, then the skill tells Claude Code how to run them. Are these skills free? All 5 are open license. Check each license in the table before you use it at work. --- ## Claude Code skills for code review: 5 free picks with install commands (2026) URL: https://skillspicker.com/guides/claude-code-skills-for-code-review/ ### Claude Code skills for code review Short answer: install one general review skill and one security review skill. Good starts are Sentry's code-review and Trail of Bits' differential-review . Each one is a SKILL.md file that Claude Code loads when you ask it to review a change.

The skill tells it what to check and how to report it. Run the review before you open the PR, then again after big changes. One general skill plus one security skill covers most teams. More than that and the skills can give mixed instructions. #### Match review skills to your stack A review skill for your language or framework catches more than a general one. Our Python guide , React guide and Next.js guide list stack picks. For security review, see Claude Code security skills . For tests, see Claude Code skills for testing . #### FAQ Is there an official Claude Code code review skill? Anthropic publishes a code-review skill in its knowledge-work-plugins repo. It is in the table above. Claude Code has its own review commands, and a skill adds your team's rules on top. Can a skill review pull requests on GitHub? A skill runs inside Claude Code. Point Claude Code at the PR branch or diff and ask for a review. To post comments on GitHub you need the GitHub CLI or an MCP server. Do these skills work in Cursor or Codex? SKILL.md is a shared format. Change --agent claude-code to cursor or codex and the CLI installs to that agent's folder. How many review skills should I install? Start with 2.

It does not know which React. It may write class components in a hooks codebase, loose any types in a strict TypeScript repo, or web code in a React Native app. Performance advice drifts between versions. A skill is a SKILL.md file with instructions Claude Code loads when a task matches. A good React skill sets the rules one time, so your prompts stay short. Our database holds 220 open-license skills built for React, and 459 match a typical React project ( SkillsPicker React page ). These 6 picks cover web React and React Native.

Our Claude Code Playwright skill guide has more picks. - Unit tests: use a skill for your runner. vitest-skill is in the table. For pytest, see the Python guide . - Test quality: test-gap-audit and mutation-testing show where tests are weak. For a review pass after tests go green, see Claude Code skills for code review . #### FAQ What is the best Claude Code TDD skill? test-driven-development from obra/superpowers is a common start. It sets the red, green, refactor loop as a rule for Claude Code. Is there a skill for Jest or pytest? Yes. Our database has skills for Jest, Vitest, pytest and more. Run a scan on your repo to see the ones that match your runner. Do testing skills run my tests? The skill tells Claude Code how to write and run tests. Claude Code runs them with your normal test command. --- ## Claude skills vs MCP servers: what each one does and when to use both (2026) URL: https://skillspicker.com/guides/claude-skills-vs-mcp/ ### Claude skills vs MCP servers A skill tells an agent how to do a job. An MCP server lets the agent reach something outside itself: a database, an API, a browser, a calendar. One is know-how. The other is a connection. Most setups that work well use both. This guide compares them in Claude Code and Codex, with facts from each vendor's docs read on October 19, 2026. #### The short answer | Skill | MCP server What it is | A folder with a SKILL.md file of instructions, plus optional scripts and reference files | A program that speaks the Model Context Protocol and exposes tools, data, or prompts What it adds | Steps, rules, checklists, examples | Actions and live data the agent can call Runs as | Text the agent reads. Scripts run with the agent's own tools | A separate process or a remote HTTP endpoint Context cost | Name and description at start. Full text loads when used | Tool names and schemas. Claude Code can search tools on demand Where it lives | .claude/skills/ or .agents/skills/ | MCP config ( claude mcp add , ~/.codex/config.toml ) Works across agents | Yes, through the open Agent Skills format | Yes, MCP is an open protocol #### What a skill is The Agent Skills spec defines a skill as a directory with a SKILL.md file. The file has YAML front matter with a name and a description , then Markdown instructions. Optional folders hold scripts, reference docs, and templates. Skills load in steps. The spec says the name and description load at startup for every skill, around 100 tokens each. The full SKILL.md body loads when the agent decides to use it. Files in scripts/ or references/ load when a task needs them. The Claude Code docs say this is why a long skill costs few tokens until you call it. Good skill jobs: a code review checklist, a release procedure, a team style guide, a "how we write migrations" note, a test-first loop. #### What an MCP server is The MCP docs call MCP "an open-source standard for connecting AI applications to external systems." A server exposes tools the agent can call, such as "query this database" or "create a ticket." Claude, ChatGPT, VS Code, and Cursor all support it. Good MCP jobs: read your issue tracker, query production logs, drive a browser, search docs that change each day, call a paid API with your key. An MCP server runs code with your access. Review what a server can do before you add it. #### Where plugins fit A Claude Code plugin is a package. The plugins docs describe it as "a directory of skills, agents, hooks, MCP servers, or other components" that loads as one unit. The docs say skills and MCP servers both work without a plugin. Use a plugin when you want to ship several pieces together or get updates from a marketplace. Codex works the same way. Its skills docs say plugins can bundle one or more skills with MCP server settings. So "plugins vs skills vs MCP" is not a three-way choice. A plugin is a box. Skills and MCP servers are what you put in it. #### When to pick which - The agent knows how but lacks access. Add an MCP server. Example: it can write SQL, but it cannot see your database. - The agent has access but does the task wrong. Add a skill. Example: it can run your deploy script, but it skips the smoke test. - Both. Add the MCP server, then write a skill that says when and how to call its tools. Codex lets a skill declare an MCP tool it depends on in agents/openai.yaml . - You keep pasting the same prompt. That is a skill. The Claude Code docs say to make one when "you keep pasting the same instructions, checklist, or multi-step procedure into chat." #### Context cost Both add tokens on every turn, so install what you use. - Skills. Claude Code lists every skill name and description in context. The docs say the listing budget is 1% of the model's context window. When it overflows, Claude Code drops descriptions for the skills you call least. Run /skill-doctor to see what each skill costs. - Codex skills. The Codex docs say the first skills list uses up to 2% of the context window, or 8,000 characters when the window size is unknown. - MCP. Each server adds tool definitions. The Claude Code plugin docs point to MCP tool search for how much a server adds per turn. #### A worked example SkillsPicker is an MCP server that recommends skills. Add it to Claude Code: claude mcp add --transport http skillspicker https://skillspicker.com/mcp Then ask "find agent skills for this project." The agent reads your project files, sends tag names (not code) to the recommend_skills tool, and gets back a match count and 2 picks, or the full list when we have few skills for your stack. You install the picks as skills. Here the MCP server gives access to a database of skills. The skills it finds give the know-how. See the MCP server page or run the free scan in a browser. #### FAQ Are Claude skills better than MCP? They do different jobs. Skills hold instructions. MCP servers give access to tools and data. Pick by what the agent is missing. Can a skill call an MCP server? A skill can tell the agent to use an MCP tool that you have set up. In Codex, a skill can list an MCP server as a dependency in agents/openai.yaml . Do skills work outside Claude? Yes. Claude Code and Codex both read the open SKILL.md format. Codex loads skills from .agents/skills/ . Claude Code loads them from .claude/skills/ . Is a plugin the same as a skill? No. A plugin is a package that can hold skills, agents, hooks, and MCP servers. Checked 2026-10-19. Prices and policies change.

A skill is a folder with a SKILL.md file of instructions, plus optional scripts and reference files. Codex looks for those folders in .agents/skills/ . This guide covers where Codex loads skills, how to install and call them, and how to reuse skills written for Claude Code. Facts come from the Codex skills docs , read on October 23, 2026. #### Where Codex loads skills Scope | Location | Use Repo | $CWD/.agents/skills | Skills for the folder where you start Codex Repo | $CWD/../.agents/skills | Skills for a shared parent folder in a repo Repo | $REPO_ROOT/.agents/skills | Skills for everyone who works in the repo User | $HOME/.agents/skills | Your own skills for every repo Admin | /etc/codex/skills | Skills for every user on a machine or container System | Bundled with Codex | Built-ins such as skill-creator Codex scans .agents/skills in every folder from where you start up to the repo root. It follows symlinks. If two skills share a name, Codex keeps both, and both show in the picker. Note the folder name: .agents , not .codex and not .claude . #### How to install a Codex skill Copy the folder. Put the skill folder in .agents/skills/ in your repo, or in ~/.agents/skills/ for every repo. The folder must hold SKILL.md at its top level. Use the built-in installer. In Codex, run $skill-installer with a skill name. The docs give $skill-installer linear as an example. You can ask it to pull skills from other repos. Use the skills CLI. The open source skills CLI installs from GitHub: npx skills add owner/repo --skill skill-name --agent codex npx skills add owner/repo --skill skill-name --agent codex -g The -g flag installs to your user folder in place of the project. The docs say Codex picks up new skills on its own. If one does not appear, restart Codex. #### How to use skills in Codex The docs list two ways: - Call it by name. In Codex CLI or the IDE extension, run /skills or type $ and pick the skill. - Let Codex choose. Codex reads each skill's name and description at start. When your request matches a description, it loads the full SKILL.md. Write descriptions with the trigger words up front. The docs say Codex shortens descriptions first when many skills are installed. #### How much context skills use in Codex The docs say the first skills list uses up to 2% of the model's context window, or 8,000 characters when the window size is unknown. You can change the budget with skills.max_context_tokens , up to 10,000 tokens. With a large set, Codex may leave some skills out of the list and show a warning. The budget covers the list. A skill Codex picks loads in full. To turn a skill off without deleting it, add this to ~/.codex/config.toml and restart Codex: [[skills.config]] path = "/path/to/skill/SKILL.md" enabled = false #### How to use Claude skills in Codex Claude Code and Codex both follow the Agent Skills spec . A skill written to that spec works in both. - Copy or symlink the folder from .claude/skills// to .agents/skills// . Codex follows symlinks, so one copy can serve both agents. - Check the front matter. The spec fields are name , description , license , compatibility , metadata , and allowed-tools . The Claude Code docs list extra fields such as disable-model-invocation and context: fork . Those are Claude Code features. - Check the body. A line such as !`git diff HEAD` is Claude Code's dynamic context injection, a Claude Code feature. Do not count on Codex to run it. Rewrite it as a step: "Run git diff HEAD and read the output." - Install with npx skills add owner/repo --agent codex claude-code to put the skill in both places in one step. #### Options for Codex alone A skill can include agents/openai.yaml . It sets a display name, icons, and a default prompt for the ChatGPT desktop app. It can set allow_implicit_invocation: false so Codex runs the skill when you call it by name and not on its own. It can list tool needs, such as an MCP server URL. The docs suggest plugins when you want to share skills beyond one repo. A plugin can bundle several skills with MCP server settings. #### Find skills for your project SkillsPicker indexes open-license SKILL.md files from public GitHub repos and matches them to your stack. See skills for Codex for install commands, or run the free scan on your repo. It shows the match count and 2 picks, or the full list free when we have few skills for your stack. You can add the SkillsPicker MCP server to Codex in ~/.codex/config.toml : [mcp_servers.skillspicker] url = "https://skillspicker.com/mcp" #### FAQ Where are Codex skills stored? In .agents/skills/ in your repo, ~/.agents/skills/ for your user, and /etc/codex/skills for a whole machine. How do I call a skill in Codex? Type $ and the skill name, or run /skills . Codex can pick a skill when your request matches its description. Can I use Claude Code skills in Codex? Yes. Copy or symlink the folder into .agents/skills/ . Spec fields work in both. Fields for Claude Code alone and !` command lines do not apply in Codex. Does Codex have a skills marketplace? Codex ships $skill-installer for curated skills, and it shares a plugin directory with ChatGPT for packaged skills. --- ## Cursor rules for Next.js: 5 free .mdc rule files with install lines (2026) URL: https://skillspicker.com/guides/cursor-rules-for-nextjs/ ### Cursor rules for Next.js Short answer: a Cursor rule is a .mdc file in .cursor/rules/ that tells Cursor how to write code for your project. Start with one general Next.js rule, then add rules for the libraries you use. Our database holds 104 open-license Cursor rules tagged Next.js.

Open the file and trim what does not fit your project before you commit it. #### How to pick rules - One general rule for the language or framework. - One rule per main library you use. Skip rules for libraries you do not use, since each one adds to the prompt. - Your own rule for team habits: folder layout, naming, test commands. Next.js changed a lot between versions. Read a rule before you add it and check that it matches your version and router. For React without Next.js, see Cursor rules for React . For Claude Code skills, see the Next.js guide and the Next.js skills page . #### FAQ Where do Cursor rules go? In .cursor/rules/ at the root of your repo, as .mdc files. Cursor reads them for that project. Commit the folder so your team gets the same rules. Should I use .cursorrules or .cursor/rules? Cursor's docs describe project rules as .mdc files in .cursor/rules/ . The install lines above use that folder. Do Cursor rules work in Claude Code? Not as is. Claude Code reads SKILL.md skills and CLAUDE.md. Our scan finds both Cursor rules and skills for your repo. Are these rules free? Yes. Each one shows its license in the table. #### Sources - https://cursor.com/docs/rules - https://skillspicker.com/for/cursor/ --- ## Cursor rules for Python: 5 free .mdc rule files with install lines (2026) URL: https://skillspicker.com/guides/cursor-rules-for-python/ ### Cursor rules for Python Short answer: a Cursor rule is a .mdc file in .cursor/rules/ that tells Cursor how to write code for your project.

For Claude Code skills, see the React guide and the React skills page . --- ## Cursor rules vs agent skills: which to use, and how to move rules to skills (2026) URL: https://skillspicker.com/guides/cursor-rules-vs-agent-skills/ ### Cursor rules vs agent skills Short answer: use a rule for guidance Cursor should see on every request, or on every file that matches a pattern. Use a skill for a task with steps, scripts or reference files that Cursor should load when the task comes up. Cursor supports both. Rules live in .cursor/rules/ as .mdc files. Skills live in .agents/skills/ or .cursor/skills/ as folders with a SKILL.md file. Facts below come from the Cursor rules docs and the Cursor skills docs , read on October 27, 2026. #### The difference in one table | Cursor rule | Agent skill File | One .mdc file | A folder with SKILL.md , plus optional scripts/ , references/ , assets/ Project folder | .cursor/rules/ | .agents/skills/ or .cursor/skills/ Global folder | User Rules in Customize (not files) | ~/.agents/skills/ or ~/.cursor/skills/ Front matter | description , globs , alwaysApply | name , description (required), plus paths , disable-model-invocation and more How it loads | Rule text goes at the start of the model context when it applies | Agent sees the name and description, then loads the skill when it fits the task Call it by hand | @rule-name in chat | /skill-name in Agent chat Works in other agents | No, .mdc rules are a Cursor format | Yes, SKILL.md is the open Agent Skills spec #### How Cursor rules load The rules docs list four project rule types. The front matter decides which one you get: Front matter | When Cursor uses the rule alwaysApply: true | Every chat session globs set, alwaysApply: false | When a file that matches the pattern is in context description set, no globs | When Agent reads the description and decides it fits None of the three | When you @-mention the rule in chat Cursor ignores a plain .md file in .cursor/rules/ . The file needs the .mdc extension. If you want plain markdown with no front matter, the docs point to AGENTS.md in the project root. Cursor reads nested AGENTS.md files in subfolders. Rules do not change Cursor Tab. They apply to Agent. #### How agent skills load At start, Cursor finds every skill in its skill folders and shows Agent the name and description of each. Agent loads a skill when the request matches. Files in scripts/ and references/ load when the skill asks for them, so a large skill does not fill the context on every turn. You can type / in Agent chat and pick a skill by name. Set disable-model-invocation: true in the front matter to make a skill work like a slash command, so it runs when you call it and Agent does not pick it on its own. Two front matter fields matter for the rules comparison: - paths scopes a skill to files that match glob patterns, the same job globs does for a rule. Cursor accepts globs on older skills as a fallback. - Nested folders scope a skill to part of a monorepo. A skill in apps/web/.cursor/skills/ shows up when Agent works on files under apps/web/ . Cursor loads skills from .claude/skills/ , .codex/skills/ , ~/.claude/skills/ and ~/.codex/skills/ . A skill you wrote for Claude Code or Codex works in Cursor with no copy. #### When to pick a rule - Team-wide standards: a copyright header, a ban on edits in dist/ , naming rules. These belong on every request, so use alwaysApply: true . - File-type conventions: "use named exports in src/components/**/*.tsx ". A rule with globs fits. A skill with paths can do the same job, but the rule is shorter. - Short guidance: the docs say to keep rules under 500 lines and split large ones. Our guides list free rule files by stack: Next.js , React and Python . #### When to pick a skill - A task with steps: deploy, release, test-driven fixes, a debug routine. - The task needs scripts or templates: a skill can ship scripts/deploy.sh and tell Agent when to run it. A rule can point to a file, but it cannot bundle one. - You use more than one agent: the same SKILL.md works in Cursor, Claude Code, Codex and other agents that follow the spec. - You want it out of context until needed: a skill costs a name and a description until Agent loads it. Three free skills to try in Cursor: Skill | Repo | What it does | Install test-driven-development | obra/superpowers (MIT) | Write the test first, then the code | npx skills add obra/superpowers --skill test-driven-development --agent cursor systematic-debugging | obra/superpowers (MIT) | Find the root cause before a fix | npx skills add obra/superpowers --skill systematic-debugging --agent cursor webapp-testing | anthropics/skills | Test a local web app with Playwright | npx skills add anthropics/skills --skill webapp-testing --agent cursor The npx skills command is the open skills CLI . Its agent list puts Cursor skills in .agents/skills/ for a project and ~/.cursor/skills/ with -g . Cursor reads both. Cursor ships /create-skill and /create-rule to write new ones from chat. #### How to move rules to skills Cursor 2.4 added a built-in /migrate-to-skills skill. Type it in Agent chat. It converts: - Rules with no globs and alwaysApply off or unset. These become standard skills. - Slash commands. These become skills with disable-model-invocation: true , so they run when you call them. It leaves rules with alwaysApply: true or globs as rules, since those have their own trigger. It does not touch User Rules, because they are not files. Check the new skills in .cursor/skills/ before you commit them. A setup that works for most repos: keep always-on standards and file-pattern rules as .mdc files, and move task playbooks to skills. #### Find rules and skills for your repo SkillsPicker indexes open-license Cursor rules and SKILL.md skills from public GitHub repos and ranks them for your stack. See skills for Cursor or browse skills by stack . For the SKILL.md fields, see the SKILL.md format guide . For the Claude side, see Claude skills vs MCP . #### FAQ Does Cursor support agent skills? Yes. Cursor loads skills from .agents/skills/ and .cursor/skills/ in the project, and from ~/.agents/skills/ and ~/.cursor/skills/ for your user. Are Cursor rules being replaced by skills? No. The docs cover both. /migrate-to-skills converts rules that Agent picks by description, and it leaves always-on and file-pattern rules in place. Can I use Claude Code skills in Cursor? Yes. Cursor reads .claude/skills/ and ~/.claude/skills/ . Fields that are Claude Code features may not apply in Cursor. Where is the Cursor global skills folder? ~/.cursor/skills/ or ~/.agents/skills/ . Of the two, ~/.cursor/skills/ is the one that can sync to Cloud Agents, with Sync Skills for Cloud Agents turned on . What about .cursorrules and AGENTS.md? The current rules docs describe .mdc files in .cursor/rules/ and AGENTS.md . Use AGENTS.md for plain markdown instructions with no front matter. Checked 2026-10-27. Prices and policies change. Confirm on the source before you buy. --- ## Gemini CLI skills: where they live, how to install them, and 3 to try (2026) URL: https://skillspicker.com/guides/gemini-cli-skills/ ### Gemini CLI skills Yes, Gemini CLI supports agent skills. A skill is a folder with a SKILL.md file. The file holds a name, a description and instructions. Gemini CLI reads the name and description of each skill at the start of a session. When your request matches a description, it asks for your consent to activate the skill, and loads the full instructions ( Gemini CLI skills docs ). Skills use the same SKILL.md format as Claude Code, Codex and Cursor. A skill from GitHub can work in each of them. #### Where Gemini CLI looks for skills Gemini CLI finds skills in four tiers, lowest to highest precedence ( docs ): - Built-in skills that ship with Gemini CLI. - Extension skills bundled in extensions. - User skills in ~/.gemini/skills/ or ~/.agents/skills/ . - Workspace skills in .gemini/skills/ or .agents/skills/ in your project. The .agents/skills/ alias works with other agents that follow the Agent Skills standard. One folder can serve Gemini CLI and Codex in the same repo. Workspace skills load when the folder is trusted. Run /trust in the session if a project skill does not show up ( getting started tutorial ). #### How to install a skill From a Git repo. Gemini CLI installs skills from a repo URL: gemini skills install https://github.com/google-gemini/gemini-skills.git --path skills/gemini-api-dev --path points to the skill folder inside the repo. --scope workspace installs to the project in place of your user folder. --consent skips the confirm prompt. With the skills CLI. The open skills CLI has a gemini-cli agent flag. It installs to .agents/skills/ in the project, or to ~/.gemini/skills/ with -g : npx skills add google-gemini/gemini-skills --skill gemini-api-dev --agent gemini-cli By hand. Copy the skill folder into one of the folders above. #### Commands to manage skills In a session: - /skills list shows the skills Gemini CLI found. - /skills disable and /skills enable turn a skill off and on. - /skills reload picks up new or changed skills. In the terminal: - gemini skills list --all lists every skill, built-in skills included. - gemini skills uninstall --scope workspace removes a project skill. - gemini skills link . links a skill you are writing to your user folder for tests. #### 3 skills to try 1. gemini-api-dev ( google-gemini/gemini-skills , Apache-2.0) For code that calls the Gemini API: text, chat, images, speech, function calling and structured output. 2. review-duplication ( google-gemini/gemini-cli , Apache-2.0) The Gemini CLI repo keeps this skill in its own .gemini/skills/ folder. During a code review it looks for duplicated code and shared utilities you could reuse. It is a good model of a team skill. npx skills add google-gemini/gemini-cli --skill review-duplication --agent gemini-cli 3. python-anti-patterns ( wshobson/agents , MIT) A checklist of bad Python practices for reviews. It is not Gemini-specific. It shows that a skill written for other agents can install into Gemini CLI. npx skills add wshobson/agents --skill python-anti-patterns --agent gemini-cli Read each SKILL.md before you install. A skill can tell the agent to run scripts. #### How to write a Gemini CLI skill Ask Gemini CLI to make one. The built-in skill-creator skill builds the folder, the SKILL.md and the scripts/ , references/ and assets/ folders ( docs ). To write one by hand, follow the rules in the tutorial : - The file name must be SKILL.md , at the root of the skill folder or one level down. - The front matter comes first and holds name and description . - The skill name comes from name: , not from the folder name. - The description decides when Gemini CLI uses the skill. Name the tasks and the words that should trigger it. Our SKILL.md format guide covers the fields in more depth. #### Skills vs GEMINI.md GEMINI.md holds context that applies to every session in a project. A skill loads on demand, when a task matches. Put your project facts in GEMINI.md. Put a procedure you run for some tasks in a skill. #### Find skills for your repo Our database lists open-license skills from GitHub with an install command for each. The free scan reads your repo URL or a description and shows how many skills match, plus 2 picks. The full curated list costs $9, paid one time: up to 30 picks ranked, with install commands and a reason for each ( pricing ). #### FAQ Does Gemini CLI support agent skills? Yes. It reads SKILL.md files from built-in, extension, user and workspace folders. Where is the Gemini CLI skills folder? ~/.gemini/skills/ for your user skills and .gemini/skills/ in a project. The .agents/skills/ alias works in both places. Can I use Claude Code skills in Gemini CLI? The SKILL.md format is shared. Install the skill with --agent gemini-cli or copy the folder. Read it first: a skill can point to tools that Gemini CLI does not have. Does Gemini CLI have a skills marketplace? Skills install from Git repos and from extensions. Our database lists open-license skills from many repos, with an install command for each. #### Sources - https://geminicli.com/docs/cli/skills/ - https://geminicli.com/docs/cli/creating-skills/ - https://geminicli.com/docs/cli/tutorials/skills-getting-started/ - https://github.com/google-gemini/gemini-skills/blob/main/skills/gemini-api-dev/SKILL.md - https://github.com/google-gemini/gemini-cli/blob/main/.gemini/skills/review-duplication/SKILL.md - https://github.com/wshobson/agents/tree/main/plugins/python-development/skills/python-anti-patterns --- ## How to install Claude Code skills: folders, GitHub, and global installs (2026) URL: https://skillspicker.com/guides/how-to-install-claude-code-skills/ ### How to install Claude Code skills A Claude Code skill is a folder with a SKILL.md file in it. To install one, you put that folder where Claude Code looks for skills. There are three ways to do that: copy the folder by hand, run a one-line install from GitHub, or add a plugin that bundles skills. This guide covers each method, the folder paths, and how to check that the skill loaded. Facts come from the Claude Code docs, read on October 19, 2026. #### Where Claude Code looks for skills The Claude Code skills docs list these locations: Scope | Path | Loads in Personal | ~/.claude/skills//SKILL.md | All your projects on this machine Project | .claude/skills//SKILL.md | Sessions in this repo. Commit it to share with your team Nested | /.claude/skills//SKILL.md | Sessions that work on files in that folder Plugin | /skills//SKILL.md | Wherever the plugin is on, as /plugin-name:skill-name A "global" install means the personal folder. On a Mac or Linux, ~ is your home folder. On Windows, it is C:\Users\ . If the same skill name sits in both places, the docs say the personal copy wins over the project copy. #### Method 1: copy the folder - Find the skill folder in its repo. It holds a SKILL.md file and may hold scripts/ , references/ , or assets/ folders. - Copy the whole folder into ~/.claude/skills/ for every project, or into .claude/skills/ in your repo for one project. - Keep the folder name the same as the name field in SKILL.md. The Agent Skills spec requires the two to match. - Start Claude Code with claude in your project. The docs say Claude Code watches the skills folders and picks up a new skill in the same session. If you made the top-level skills folder after the session started, run /reload-skills . #### Method 2: install from GitHub with npx skills The open source skills CLI copies or links skills from a Git repo into each agent's folder. You need Node.js. # list the skills in a repo npx skills add owner/repo --list # install one skill for Claude Code in this project npx skills add owner/repo --skill skill-name --agent claude-code # install it for your user, in every project npx skills add owner/repo --skill skill-name --agent claude-code -g The CLI takes a GitHub shorthand, a full GitHub URL, a direct link to one skill folder, a GitLab URL, or a local path. By default it symlinks files. Add --copy to copy them. #### Method 3: install a plugin A plugin is a folder of skills, agents, hooks, or MCP servers that Claude Code loads as one unit. The plugins docs say to run /plugin in a Claude Code session and pick one from the Discover tab. Plugins come from a marketplace, which is a repo with a .claude-plugin/marketplace.json file. Use a plugin when you want a full setup from someone else with updates. Use a plain skill folder when you want one skill. The docs note that each enabled plugin puts the name and description of its skills into context on every turn, so turn off plugins you do not use. #### Check that the skill loaded - Type / in Claude Code. Your skill shows in the menu under its folder name. - Run it by name, for example /summarize-changes . - Or ask a question that matches its description. Claude loads the skill when the task fits. #### If the skill does not show up - Wrong depth. The path must be skills//SKILL.md . A SKILL.md one folder deeper or higher than that does not load. - Nested folder. Skills in a .claude/skills/ below where you started Claude Code load the first time Claude reads or edits a file there. - Cloud or Cowork session. The docs say those sessions do not read ~/.claude/skills/ . Commit the skill to the repo. - Reserved names. Do not name a folder synced . Claude Code uses that name for skills synced from claude.ai. #### Which skills to install The hard part is picking. Public repos hold tens of thousands of SKILL.md files, and many overlap. SkillsPicker matches them to your project. Paste a repo URL or describe your stack on the free scan . It shows the match count and 2 picks, or the full list free when we have few skills for your stack. Each pick comes with its install command. See skills for Claude Code or browse by stack, such as Next.js or Python . #### FAQ Where are Claude Code skills stored? Personal skills live in ~/.claude/skills// . Project skills live in .claude/skills// in your repo. How do I install a Claude Code skill from GitHub? Run npx skills add owner/repo --skill skill-name --agent claude-code . Or clone the repo and copy the skill folder into .claude/skills/ . How do I install a skill for all projects? Put it in ~/.claude/skills/ , or add -g to the npx skills add command. Do I need to restart Claude Code after I add a skill? No. Claude Code watches the skills folders and picks up changes in the same session. If you created the skills folder after you started, run /reload-skills . #### Sources - https://skillspicker.com/for/claude-code/ --- ## SKILL.md format: fields, folder layout, and a template you can copy (2026) URL: https://skillspicker.com/guides/skill-md-format/ ### SKILL.md format A skill is a folder. The one file it must hold is SKILL.md: YAML front matter between --- lines, followed by Markdown instructions. The Agent Skills spec sets the rules, and Claude Code, Codex, and other agents read the same file. This guide covers the required fields, the optional ones, the folder layout, size limits, and the extra fields each agent reads. Facts come from the spec and vendor docs, read on October 23, 2026. #### Folder layout my-skill/ SKILL.md required: front matter + instructions scripts/ optional: code the agent can run references/ optional: docs the agent reads when needed assets/ optional: templates, images, data files Codex adds one more optional file, agents/openai.yaml , for display name, icon, and tool dependencies. #### Required fields Field | Rules from the spec name | 1 to 64 characters. Lowercase letters, numbers, and hyphens. No hyphen at the start or end. No double hyphens. Must match the folder name. description | 1 to 1,024 characters. Say what the skill does and when to use it. Include the words a user would type. The spec gives a good description: "Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents or when the user mentions PDFs, forms, or document extraction." And a poor one: "Helps with PDFs." Claude Code is looser. Its docs say all fields are optional in Claude Code, name defaults to the folder name, and description defaults to the first line of the body. Write both anyway, so the skill works in every agent. #### Optional fields in the spec Field | Use license | License name, or the name of a bundled license file compatibility | Up to 500 characters on what the skill needs: product, packages, network metadata | Key-value pairs, such as author and version allowed-tools | Tools the skill may use without asking. Marked experimental #### A template you can copy --- name: release-checklist description: Runs our release steps for a web app. Use when the user asks to cut a release, tag a version, or ship to production. license: MIT metadata: author: your-team version: "1.0" --- # Release checklist ## Steps 1. Run the test suite. Stop if any test fails. 2. Update CHANGELOG.md with the changes since the last tag. 3. Bump the version in package.json. 4. Tag the commit and push the tag. ## Rules - Do not skip step 1. - Ask before you push to main. ## More detail See [the deploy notes](references/deploy.md). #### Size limits and loading The spec says agents load skills in three steps: - Name and description, about 100 tokens, load at startup for every skill. - The SKILL.md body loads when the agent picks the skill. The spec suggests under 5,000 tokens and under 500 lines. - Files in scripts/, references/, assets/ load when a task needs them. Move long reference material into references/ . Keep links one level deep from SKILL.md, with relative paths. In Claude Code, the description and when_to_use text share a cap of 1,536 characters in the skill listing. Put the main use case first. #### Extra fields in Claude Code The Claude Code docs list fields beyond the spec. A few you will use: - disable-model-invocation: true so the skill runs when you type /name and not on its own. - user-invocable: false to hide it from the / menu for background knowledge. - when_to_use for trigger phrases. - argument-hint and arguments for skills that take input. - context: fork to run the skill in a subagent. The body can hold a line like !`git diff HEAD` . Claude Code runs the command and puts its output in the skill before Claude reads it. The docs call this dynamic context injection. It does not work on claude.ai or the API. If you upload a skill to claude.ai or use the Skills API, the docs say the six spec fields pass and no others. Any other field fails the upload with an "Unexpected key(s)" error. #### How to create a skill - Make a folder named for the skill, such as ~/.claude/skills/release-checklist/ for Claude Code or .agents/skills/release-checklist/ for Codex. - Add SKILL.md with name , description , and your steps. - Check it with the spec's validator: skills-ref validate ./release-checklist . - Test it. In Claude Code, type /release-checklist . In Codex, type $release-checklist . Next, ask a question that matches the description and see if the agent picks it. Both vendors ship a skill that writes skills. Codex has $skill-creator . Claude Code docs describe running evals with skill-creator. #### Before you write one, check what exists Public repos hold tens of thousands of SKILL.md files under open licenses. SkillsPicker indexes them and matches them to your stack. The free scan shows the match count and 2 picks (or the full list free when we have few skills for your stack), so you can see if someone has written yours. Browse by stack, such as React or Go . #### FAQ What is the SKILL.md format? A Markdown file with YAML front matter. name and description are required by the spec. The body holds instructions with no fixed structure. Does the folder name have to match the name field? Yes, under the Agent Skills spec. Claude Code uses the folder name when name is missing. How long can a SKILL.md file be? The spec suggests under 500 lines and under 5,000 tokens for the body. Put the rest in references/ . Does the same SKILL.md work in Claude Code and Codex? Yes, if you stick to the spec fields. Fields for Claude Code alone do not carry over to other agents. --- ## SkillsPicker pricing: free scan, $9 curated skill list URL: https://skillspicker.com/pricing/ ### Pricing The scan is free.

The CLI reads your file names and manifest files on your machine, turns them into tags such as "typescript" or "testing", and sends those tags. Your code stays on your machine. #### Run it with npx npx -y https://skillspicker.com/skillspicker-cli.tgz #### Or download and run with Node 18+ curl -fsSL https://skillspicker.com/cli.mjs -o skillspicker.mjs node skillspicker.mjs # scan the current folder node skillspicker.mjs ../my-app # scan another folder node skillspicker.mjs --dry-run # print the tags, send nothing #### What it reads and sends - Reads: file names (skipping node_modules, .git, build folders) and manifests such as package.json, pyproject.toml, requirements.txt, go.mod, Cargo.toml, Gemfile, composer.json, Dockerfile and README.md. - Sends: a list of tag names, for example ["nextjs","supabase","tailwind","testing","typescript"] . Nothing else. - Prints the tags before it sends them. Use --dry-run to check first. The script is one readable file with no dependencies. Read it before you run it: cli.mjs . The tag list is public at rules.json . --- ## MCP server: recommend agent skills from your editor | SkillsPicker URL: https://skillspicker.com/mcp-server/ ### MCP server Let your coding agent find skills for the project it is working on. The agent derives tags from local files and sends those, so code stays on your machine. Endpoint: https://skillspicker.com/mcp Transport: Streamable HTTP. Auth: none. Read-only. Tools: recommend_skills , search_skills , list_skill_tags . #### Add it Claude Code Cursor (.cursor/mcp.json) { "mcpServers": { "skillspicker": { "url": "https://skillspicker.com/mcp" } } } VS Code / GitHub Copilot (.vscode/mcp.json) { "servers": { "skillspicker": { "type": "http", "url": "https://skillspicker.com/mcp" } } } Codex (~/.codex/config.toml) #### HTTP API No MCP client? GET https://skillspicker.com/api/recommend?tags=nextjs,supabase,testing or ?q=your project in words returns the same free result as JSON. Spec: openapi.json . #### The tools recommend_skills takes tags (preferred), description or repo_url . With no input it returns a sample for a Next.js project. search_skills takes one query , for example "stripe webhooks". list_skill_tags takes no input and returns the tag names. Each search returns the match count, 2 free picks with install commands, and a link to the full curated list ($9 once). Tag names: rules.json . Example prompt: "Use skillspicker to find skills for this repo. Derive tags from package.json first." --- ## Agent skills by stack and agent | SkillsPicker URL: https://skillspicker.com/skills/ ### Agent skills by stack and by agent 37 stack pages.

Fieldnote Labs in Missouri, USA, runs it. #### What we collect No accounts. No ads or trackers. No cookies from us. We do not sell or share personal data. #### Analytics We run our own counter, with no third-party analytics script. When a page loads, your browser sends the page path and the host name of the site that linked you. If the link has a campaign tag (utm_source and utm_campaign), your browser sends those two tags. When you run a scan, see results, click to check out or open a paid list, your browser sends that action name. Our server counts scans, API calls and MCP calls per day by input type and client type, such as browser or curl. It keeps that short label, not the full user agent. We store daily totals. We do not store your IP address, a cookie or an ID. To drop repeat actions, a one-way hash of your IP address, the action and the date sits in the Cloudflare cache for 10 minutes. #### Repo scans When you paste a GitHub repo URL, our server asks the public GitHub API for the repo's file list and reads a few manifest files (such as package.json, pyproject.toml, go.mod, Dockerfile and README.md) from GitHub. We turn them into tags and discard the files. We keep the repo's file list (file paths, no contents) for 24 hours so a repeat scan does not ask GitHub again. #### Text scans A project description goes to our server, which picks tags from it and discards the text. #### Local CLI and MCP tool The local CLI reads your project on your machine and sends the tag names and nothing else, for example "nextjs" or "testing". It sends no code, file names or file contents. The MCP tool receives the tags, description or repo URL your agent passes and handles them like the scans above. #### Scan log To check and improve picks, we log each scan without personal data: the tags we found, the input type (repo, text, tags), the ranking method, the time to the minute, and the IDs of the top 5 picks. For a repo scan the log holds the repo name, since that repo is public on GitHub. We do not log the text of a description, your IP address or your browser. Logs expire after 30 days. #### Scan links A scan code encodes the tags of a scan, nothing more. Anyone with the link sees the same free result. #### Payments Polar (polar.sh) is the merchant of record and runs checkout. It collects your name, email, billing address and card details under its own privacy policy , and may set its own cookies in checkout. We do not see your card number. Polar tells us when an order is paid or refunded. We store the checkout id, order id, customer id and the scan code for that order in Cloudflare storage so your list opens after payment. When you open a list with a license key, we check the key with Polar and store a one-way hash of the key with the scan it unlocked. To stop abuse, our server counts scans per IP address in the Cloudflare cache for 10 minutes, under a one-way hash. It is not stored anywhere else. #### Hosting Cloudflare hosts this site and processes your IP address, browser type and the pages you request to serve and protect it.

We do not sell the skills. Each skill belongs to its authors and comes under its own license, shown next to it. Read a skill before you install it. Skills give instructions to your agent, and some include scripts. #### No placement for sale Rank comes from fit with your project tags. Authors cannot pay for listing or rank. #### Payment Polar (polar.sh) is the merchant of record and sells you the product. Its terms apply to the purchase. A license key is for you or your team, for the scan it unlocks. #### No warranty We check licenses and match tags with care, but the list comes as is. We are not responsible for third-party skills or what they do in your environment. Our liability is limited to the amount you paid us. #### Fair use Do not scrape the scan API or resell lists.

For each skill it reads the frontmatter (name and description) and the license. It lists a skill when the license is open (MIT, Apache-2.0, BSD, ISC, MPL, CC0, CC-BY, GPL and similar) and drops the rest. It stores the name, a one-line description, tags, the license and the link. It uses the GitHub API with conditional requests to keep load low and names itself in its user agent. #### How we make money The scan is free. We charge $9 for the full curated list of a scan. We do not sell placement, run ads or sell data. #### Remove a skill Authors can ask us to drop a skill: email nichols-ventures@mail.grokbot.com with the repo link.

Below: what coding agents get wrong on Next.js, 3 picks to start with, and where each agent loads them. Updated 2026-10-23. Tags used for this page: typescript, react, nextjs. #### What coding agents get wrong in Next.js Agents mix the App Router and the old Pages Router in one answer. They put hooks in Server Components, forget the 'use client' line, and fetch data in useEffect where a server fetch fits. Caching rules changed between versions, so stale advice is common. #### Skills that help Skills that state App Router patterns, data fetching and caching rules. Add a testing skill for components and routes, and a review skill for server and client boundaries. Cursor rules: the database holds 98 Cursor rule files (.mdc) tagged Next.js . Cursor reads them from .cursor/rules/ . Other agents load SKILL.md skills, so most picks here are skills. #### 3 picks to start with These 3 fit Next.js in general. The scan box opens with a sample Next.js description you can edit. A scan reads your repo or description, shows the match count and 2 picks free, and the full curated list (up to 30 picks with install commands, reasons and overlap notes) costs $9 once. Scan a Next.js project free Use the MCP tool #### Where each agent loads Next.js skills - Claude Code : project folder .claude/skills/ , install flag --agent claude-code - Cursor : project folder .cursor/skills/ or .agents/skills/ , install flag --agent cursor - Codex : project folder .agents/skills/ , install flag --agent codex - GitHub Copilot : project folder .github/skills/ or .agents/skills/ , install flag --agent github-copilot npx skills add owner/repo --skill skill-name --agent claude-code #### How we count We match project tags against 90,454 skills from 6,521 public GitHub repos (refreshed 2026-10-23). A skill built for another framework or language is left out, and so is a skill below our relevance floor. The picks on this page come from the ranked list for these tags. We favor broad practice skills over single-task ones. Licenses are shown as each repo declares them. Read a skill before you install it. #### Questions **What agent skills should I use for Next.js?** Start with a broad practice skill built for Next.js, then add skills for testing and review. In our database 196 skills are tagged for Next.js and 648 skills match a typical Next.js project. The picks on this page are a place to start. A scan of your repo ranks the full list for your tasks. **Do I need a skill if my agent knows Next.js?** A skill pins the version and the patterns your team uses. Without one, the agent draws on mixed training data, which holds a lot of old Pages Router code. **Are there Cursor rules for Next.js?** Yes. The database holds 98 Cursor rule files (.mdc) tagged Next.js. Cursor loads them from .cursor/rules/. Claude Code, Codex and Copilot do not read .mdc rules, so pick SKILL.md skills for those agents. **Where do Next.js skills go for Claude Code, Cursor, Codex and Copilot?** Claude Code reads .claude/skills/, Cursor reads .cursor/skills/ or .agents/skills/, Codex reads .agents/skills/, and GitHub Copilot reads .github/skills/ or .agents/skills/. The install command takes --agent with the agent name and copies the skill folder there. **Why 3 picks here?** The right list depends on your exact stack and tasks. Run a free scan for your project to see its match count and 2 picks.

Below: what coding agents get wrong on React, 3 picks to start with, and where each agent loads them. Updated 2026-10-23. Tags used for this page: typescript, react. #### What coding agents get wrong in React Agents add useEffect for derived state, skip keys in lists, and reach for global state when props would do. They write class components or old lifecycle code from training data. Tests check markup, not behavior. #### Skills that help Skills for component patterns and the rules of hooks, plus tests in the React Testing Library style and an accessibility check.

Below: what coding agents get wrong on Python, 3 picks to start with, and where each agent loads them. Updated 2026-10-23. Tags used for this page: python. #### What coding agents get wrong in Python Agents skip type hints, catch broad exceptions, and use mutable default arguments. They pip install into the global environment and ignore the project tool, such as uv or Poetry. Tests come out as unittest classes in a pytest repo. #### Skills that help Skills for typed, idiomatic Python, pytest patterns and packaging.
