Your AI agent wrote React. That does not mean it should ship.

Most AI coding workflows fail because the model writes the code, explains the code, and then quietly convinces you the code is fine.

AgentProof React treats AI-generated React and Next.js code as untrusted until deterministic gates pass.

npx agentproof-react check

Bad React in. Review report out. No model self-grading.

It follows the same production-agent safety pattern as agent-approval-gate: models can draft, but deterministic gates decide what moves forward.

Run the bad fixture first:

npm run demo:bad

It exits with code 1 because the fixture contains common generated-code failures that should block shipping.

Example output:

AgentProof React
Deterministic review gates for AI-generated React.

Checked 1 React/Next.js source file.

❌ Errors: 6
⚠️  Warnings: 4

❌ Client component imports server-only APIs
   examples/bad/UserList.tsx:3:1
   Rule: next/no-server-import-in-client-component
   Why: AI agents frequently cross Next.js server/client boundaries.
   Fix: Move server logic to a server component, route handler, server action, or API boundary.

❌ Unstable index key in mapped list
   examples/bad/UserList.tsx:26:17
   Rule: react/no-index-key

Ship verdict: BLOCKED
Reason: AI-generated code is untrusted until deterministic gates pass.

Run the good fixture:

npm run demo:good

Use directly with npx:

npx agentproof-react check

Or install it in a repo:

npm install -D agentproof-react

{
  "scripts": {
    "agentproof": "agentproof-react check --strict"
  }
}

Scan changed, staged, or untracked git files when there are any; otherwise scan the current directory:

agentproof-react check

Scan a path:

agentproof-react check src app components

Scan everything under the target path:

agentproof-react check --all

Fail on warnings too:

agentproof-react check --strict

Emit JSON for CI, bots, or PR comments:

agentproof-react check --json

Exit codes:

• 0: no errors, or warnings only without --strict
• 1: shipping is blocked by errors, or by warnings in --strict mode
• 2: CLI usage error, such as an unknown option or missing target path

AgentProof React currently checks for:

• unstable index keys in mapped lists
• useEffect derived-state patterns
• server-only imports inside Next.js client components
• buttons missing explicit type
• images missing alt
• unsanitized dangerouslySetInnerHTML
• browser globals during render
• placeholder or fake implementation text
• suspicious empty catch blocks
• leftover console statements

This is intentionally not a replacement for ESLint, TypeScript, or tests.

It is a small AI-output review gate for the problems agents commonly produce when the code looks plausible but is not safe to ship.

Normal linting asks:

Does this code violate general project rules?

AgentProof React asks:

What would an AI agent plausibly fake, forget, or cross without noticing?

Unlike generic React quality tools, AgentProof React assumes the code was generated by an agent and treats it as untrusted until deterministic checks pass.
