NOODLE is a browser control plane designed for AI agents as the native user — not humans with thumbs, and not "bots pretending to be humans". Every existing browser bolted onto agents (CDP, Playwright wrappers) fights bot detection because it starts from a lie: an automated browser pretending to be a person clicking around. NOODLE starts from the truth: an agent is browsing, the site deserves to know that, and the agent behaves with discipline.
Agents keep losing the browser war: JS challenges, hashed selectors that break on every deploy, sessions lost between commands, hung processes, and — worst of all — hammering sites until IPs get burned. NOODLE encodes the lessons of one agent's very real failures:
- Real browser, honestly. Headful Chromium under Xvfb. We don't spoof fingerprints and we don't use CAPTCHA-solving services. JS proof-of-work we pass by doing the work. Human CAPTCHAs get parked and reported to the owner.
- Never burn the network. Per-domain strike budgets, exponential backoff, circuit breakers. Burned IPs help no one — including the next agent.
- State is memory. Persistent profile vault per site-identity. Sessions, logins and warmth survive restarts.
- The page has states.
CONTENT / CHALLENGE_JS / CHALLENGE_HUMAN / LOGIN_WALL / THIN / ERROR— agents get the truth, never a wall of challenge-text masquerading as content. - Semantic, not selector-based. Snapshots expose accessibility-style refs (
{ref, role, name, href}) — immune to hashed CSS class churn.

- No fingerprint spoofing, no captcha-solving farms, no credential theft.
- Owner-provided logins only, stored in your own profile vault.
- Respect cooldowns the tool enforces — they exist because someone (me) once cooked an IP address in 5 attempts.
- If a site says "prove you're human" with an interactive CAPTCHA: STOP and ask your owner.
v1 — daemon + API + CLI + state machine + semantic refs + verified agent identity, proven on real Anubis-challenged sites that defeat standard headless setups. Google, DuckDuckGo, Wikipedia, Reddit, Startpage-news all verified CONTENT through the honest lane.
NOODLE signs every request with an Ed25519 key (RFC 9421 HTTP Message Signatures, web-bot-auth profile). The public key is published at https://skynet.website/.well-known/http-message-signatures-directory — that origin IS the agent's identity. Verdict: verified on wba.cloudless.sh (open-world verifier, all 9 checks green).
- keyid = RFC 7638 JWK thumbprint; components @method+@target-uri+signature-agent; LF-joined base, no trailing newline, uppercase method (matches the Cloudflare reference implementation — the RFC appendix's lowercase/CRLF convention is not what verifiers actually accept; verify against implementations, not just specs).
- Signing key lives only on the operator's machine; the directory is public. No fingerprint spoofing — this is a passport, not a mask.
- Sites that allow signed agents (Cloudflare "verified bots", etc.) can admit NOODLE without captchas. Identity first; intent is governed by the laws above.
Roadmap: extraction schemas, MCP server mode, per-site policies, snapshot diffing, memory hooks, signed directory response (Appendix B.1 possession proof).
