What it does
React is an agent skill from pedronauck/skills. Build React 19 components and hooks under React Compiler: state, Effects, memoization, props/refs, Actions, use(), compiler/lint setup, and Vitest tests. Excludes React Native, other frameworks, and backend-only Node.js.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `references/compiler-setup.md`, `references/compiler.md` and `references/components-and-types.md`).
It sits in Testing & QA, covering Unit testing, Cross-platform mobile apps and Linting and formatting. It works with React, Vitest, React Native and Node.js. The repository describes itself as: My personal favorite skills.
When your agent uses it
- Tasks that involve Unit testing
- Tasks that involve Cross-platform mobile apps
- Tasks that involve Linting and formatting
Example prompts
- “/react”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Read, Grep, Glob
What it can do on your machine
Read from SKILL.md and the folder at commit 0422940. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
React loads about 1.5k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 754 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 754 words (~1,520 tokens).
“Targets React 19.2 and React Compiler 1.0 (babel-plugin-react-compiler), linted by eslint-plugin-react-hooks 7.1+. Read the reference matched by the API or behavior being changed. Load adjacent references only for concerns the change crosses; reuse relevant context already read.”

Questions about React
What does React do?
Build React 19 components and hooks under React Compiler: state, Effects, memoization, props/refs, Actions, use(), compiler/lint setup, and Vitest tests. React is an agent skill from pedronauck/skills. Build React 19 components and hooks under React Compiler: state, Effects, memoization, props/refs, Actions, use(), compiler/lint setup, and Vitest tests.
When should I use React?
React fits situations like: tasks that involve Unit testing; tasks that involve Cross-platform mobile apps; tasks that involve Linting and formatting.
How do I install React in Claude Code?
Run `npx skills add pedronauck/skills --skill react -a claude-code`. Or copy the skill folder (skills/mine/react in pedronauck/skills) into .claude/skills/react in your project. Claude Code loads it when a task matches its description.
How do I install React in Codex?
Run `npx skills add pedronauck/skills --skill react -a codex`. Or copy the skill folder (skills/mine/react in pedronauck/skills) into .agents/skills/react in your project. Codex loads it when a task matches its description.
Can I use React in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pedronauck/skills --skill react -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/react, .gemini/skills/react, .github/skills/react and .opencode/skills/react in your project.
What does React need to run?
SKILL.md names no scripts, command-line tools or credentials: React is instructions for the agent only. Our summary lists: Node.js. Its frontmatter pre-approves these tools: Read, Grep, Glob.
Does React access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is React safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does React use?
No licence was found for React or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does React use?
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 16k tokens, read only when the agent opens those files.
What are the alternatives to React?
Skills that share tags, products or a category with React: React Native Testing (callstackincubator/agent-skills, 1.7k stars), Jest Testing (aiskillstore/marketplace, 430 stars), Tooling Setup (MadAppGang/claude-code, 284 stars) and Cometchat React Native Testing (cometchat/cometchat-skills, 130 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains React?
pedronauck (a GitHub user) maintains it in pedronauck/skills, which has 634 GitHub stars. The repository holds 65 skills in this directory. The repository was last updated on September 14, 2026.
