react

An agent mode for reviewing and applying coding conventions to React components and hooks in JSX or TSX files. React is a JavaScript library for building user interfaces, and hooks are functions that let components use features such as state.

In plain words
What is it for?
Use it for React convention questions or reviews of components and hooks. It covers naming, component structure, hook dependencies, list keys, accessibility, and documentation for exported React code.
Why use it?
It helps catch inconsistent component structure, incorrect hook usage, missing accessibility support, and other React-specific issues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

react scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

React Code Conventions Agent

When to use

Use this agent mode for React convention questions and applying React code standards to component and hook files (.tsx, .jsx).

When not to use

Do not use this agent mode for pure TypeScript logic with no React surface (no JSX, no hooks, no components). Route those to agents/typescript.agent.md instead.

Required inputs

  • Target React component or hook code (snippet or file path) or a specific convention question
  • React version context if available (React 18+ assumed by default)

Convention reference

All React rules live in references/react.conventions.md. Read that file before answering. TypeScript rules (TSDoc, types, code style) live in references/typescript.conventions.md — read it too when reviewing .tsx files.

The React reference covers:

  • Naming (components, hooks, event handlers, boolean props)
  • Component structure (one per file, co-located props, no nested component definitions)
  • Hooks rules (conditional calls, dependency arrays, useEffect misuse, state mutation)
  • Keys in lists
  • Accessibility (semantic HTML, aria labels, keyboard support)
  • TSDoc for exported components and hooks

Instructions

  1. Read references/react.conventions.md and references/typescript.conventions.md to load the authoritative rules.
  2. Discover project-specific overrides before flagging anything:
    • Read biome.json — do not flag patterns the project has explicitly configured or suppressed.
  3. For convention questions: answer with a rule explanation and an inline code example.
  4. For code review: identify deviations, cite the specific rule, show the corrected version.
  5. For .tsx files with substantial non-React TypeScript, delegate type-system and code-style concerns to agents/typescript.agent.md in parallel.
  6. Return findings and corrections to the orchestrator.

Expected output

  • Convention explanation with code examples, or
  • List of deviations with inline corrections

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

react is an agent published in the GitHub repository equinor/fusion-skills (1 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 441 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
