patternfly-react-seed: Instructions file for Codex

AGENTS.md

patternfly-react-seed AGENTS.md is an instructions file for Codex, OpenCode from patternfly/patternfly-react-seed. It costs 916 tokens per session, scanned A, original, MIT.

Repository instructions for a PatternFly React seed project, a starter application built with React and TypeScript. They describe the project's tools, layout, and checks for completed changes.

In plain words
What is it for?
Use them when changing this React application. They point to the commands for TypeScript checking, linting, unit tests, and test coverage, and explain that the project uses Webpack, React Router, PatternFly, and Vitest.
Why use it?
They give coding agents the local context needed to modify the project safely and catch type, lint, or test errors before work is considered finished.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is patternfly/patternfly-react-seed's own configuration. It tells Codex and OpenCode how to work on patternfly-react-seed itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything patternfly-react-seed configures →

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

patternfly-react-seed AGENTS.md 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 2mo ago.

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.

Agent instructions (PatternFly React Seed)

This file helps humans and coding agents work safely in this repository. It summarizes how the app is built, how to validate changes, and where code lives.

What this project is

Official PatternFly React seed: a small React + TypeScript app with PatternFly layout, React Router, Webpack, and Vitest. It is a reference for wiring PatternFly into a real app, not a component library.

Stack

  • React 18, TypeScript (strict), PatternFly v6 (@patternfly/react-core, @patternfly/react-icons, @patternfly/react-styles)
  • Bundler: Webpack (webpack.*.js); dev server: webpack-dev-server
  • Tests: Vitest + Testing Library (vitest.config.ts, src/test/setup.ts) — not Jest
  • Lint: ESLint on ./src/ (.tsx, .js); unused imports and variables are errors

Commands to run before you consider work done

From the repository root, after npm install:

Command Purpose
npm run type-check TypeScript (tsc --noEmit)
npm run lint ESLint on src/
npm test Vitest unit tests
npm run test:coverage Vitest with coverage (requires devDependency @vitest/coverage-v8)
npm run ci-checks Same as type-check + lint + test:coverage (run this before merging when possible)

Local development:

Command Purpose
npm run start:dev Webpack dev server
npm run build Production build into dist/

Repository layout

  • src/app/ — Application shell: routes, layout, feature pages (Dashboard, Settings, Support, NotFound)
  • src/app/AppLayout/ — Chrome (header/sidebar)
  • src/component/ — Shared or prototype components
  • src/index.tsx — Entry; dev-only react-axe wiring when not in production
  • webpack.common.js — Shared Webpack config (aliases, loaders)
  • vitest.config.ts — Test runner and @app alias for tests

Path aliases

  • @app/* → src/app/* (Webpack and Vitest)
  • @assets/* → PatternFly packaged assets under node_modules/@patternfly/react-core/dist/styles/assets/*

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.
