A2A Agent Validator — install notes

Frontend (GitHub Pages / Jekyll)
  assets/tools/a2a-validator.html

      a2a-validator.css
      a2a-validator.js          # controller (input, verdict, render)
      validator-client.js       # talks to the Worker (POST /validate)
      checks.js                 # required-field + lifecycle checklist logic

Cloudflare Worker backend

  cloudflare-worker-a2a-validator/wrangler.toml

1. Frontend (already wired)

Registered in the tools hub (assets/tools/index.html) as:

{cat:'ai', icon:'a2a', name:'A2A Agent Validator', href:'a2a-validator.html', … }

It reuses the shared tool-shell design system, so it inherits the ruslanmv.com look (dark-green hero header, warm-white cards, green accent, rounded corners, mobile responsive) with no extra setup.

Run locally

make serve        # Jekyll, then open the address it prints, e.g.
#   http://localhost:4000/assets/tools/a2a-validator.html

or any static server:

python3 -m http.server 8000
#   http://localhost:8000/assets/tools/a2a-validator.html

2. The Worker is already deployed

https://a2a-validator.cloud-data.workers.dev

The frontend defaults to that URL. The page header shows “Worker online” once /health responds.

3. Future updates

The full Worker source is vendored in cloudflare-worker-a2a-validator/worker.js. To ship an update:

cd cloudflare-worker-a2a-validator
wrangler login        # first time only
wrangler deploy

Common extension points in worker.js:

4. Point the frontend elsewhere (optional)

Edit the constant in assets/tools/assets/a2a-validator/validator-client.js:

const DEFAULT_WORKER_BASE = 'https://a2a-validator.cloud-data.workers.dev';

or override at runtime:

<script>
  window.RMV_A2A_API_BASE = "https://a2a-validator.your-subdomain.workers.dev";
</script>

5. Verify

curl https://a2a-validator.cloud-data.workers.dev/health
curl -X POST "https://a2a-validator.cloud-data.workers.dev/validate" \
  -H "Content-Type: application/json" \
  --data '{"url":"https://your-agent.example.com"}'
