TFBthumb · Beta access
Run a real workflow.
The playground refuses every consequential intent. The beta does not, but it surfaces each one to your approver before it dispatches. You hold the lever; the agent holds the wheel.
What a beta engagement looks like
- One organization key, time-bounded for 30 days, renewable.
- One API endpoint:
POST /api/v1/runwith a URL and a structured task spec. - Every consequential action surfaces as a pending approval; you call
/approveor/deny; the agent retries or halts. - Every action and every wire effect lands a hash-chained ledger receipt you can download and audit.
- Substrate is TFB-hosted in a sandboxed headless Chromium. No source ships to you.

What this does NOT promise
The full boundary list. Multi-tab, cross-origin iframes, GET-with-side-effects, LLM-Brain, unattended autonomy: all explicitly out of scope.
Evaluation agreement
One page. 30-day term. Mutual confidentiality. Acceptable-use clause. We countersign by email reply.
What is verified before your first run
The bounded-claim set on the main page is what is promised. An independent third-party reviewer (Gemini) returned verified on it. Two TFB inspectors (DAVID+ and CODE_MECHANIC) confirmed the same set against the canonical SHAs. Every claim is backed by a runnable gate; every gate prints PASS on the version your key binds to.
Beta does not extend the bounded set. It gives you access to it on your own targets, with a human-in-the-loop approver for the consequential tier.
How to request a key
Send one email · evaluation is free during validation
Paid tier is coming. While the bounded-claim set is in the public-validation phase, evaluation keys are issued at no cost to the first qualifying organizations. Subject: TFBthumb beta, <your org>. Tell me what target you want to point it at and what the success condition is. I read each one personally and reply with the agreement and a key within one business day. Saul@projecttfb.com
