From a red test to a handoff a developer can act on.

Every level includes all earlier levels of the same series: L1 START is L0-L1, L2 UNDERSTAND is L0-L2, L3 APPLY is L0-L3, and L4 SCALE is L0-L4, the complete series. Each level sits in its own folder in the download.

L4 SCALE is the whole series in one purchase: all five workflows, from the free starting point to the blueprint for running the practice across teams. It suits leads who already know they will use more than one level, or who need the top-level ownership, gates and rollout planning. If you are unsure, start with the free L0 workflow or L1 START. What you paid for any lower level of the same series counts toward any higher level (L1 START at $19 makes L4 SCALE cost $130). Each price covers that level and everything below it.

It costs the listed price of the higher level minus what you already paid for a lower level of the same series. What you paid for any lower level of the same series counts toward any higher level (L1 START at $19 makes L4 SCALE cost $130). You never pay twice for the levels below. It works for purchases made in our store or on Gumroad, and only for a higher level of the same series. To claim it, email hello@nobrainer.tech with your receipt, the level you want and the address you will use at checkout. We check the purchase and reply with a one-time link that applies the credit at checkout. The credit is personal, like the license: it is tied to that email address, and it does not apply to a purchase that was refunded.

A terminal and Node.js 22 (LTS). Two L1 START workflows, the Initial LLM Test Checklist (S2 · AI Evaluation & Reliability) and the Authorized Prompt Injection Review (S3 · AI Security Testing), start with Python 3.10 or newer instead. You unzip the package, run one command on the bundled example and open the HTML report; the command itself finishes in seconds. No particular AI assistant is needed to run the included code. In S5 · AI for Work & Business you write no code, and you still need a terminal and Node.js 22, installed once.

Paid workflow purchases carry a 7-day money-back guarantee: ask for a full refund within 7 calendar days, no questions asked, and keep the files you downloaded for personal use. They also include at least six updates in each 12-month period for five years from the purchase date, at no extra charge for those updates, made available through the platform where you bought. The update commitment covers the workflow you bought. It does not cover separate products, additional levels, custom implementation or third-party subscriptions. Your personal license does not expire when the five years end. Results vary and are not guaranteed, and mandatory consumer rights stay in place.

Our store carries all 25 workflows, L0 to L4 in five series. Gumroad carries only the ten L0 and L1 workflows and points here for L2 to L4. The L0 and L1 workflows are the same in both places. Files, receipts and updates come through the platform where you bought, and Gumroad acts as merchant of record for purchases made there, so its checkout terms apply as well.

Use sanitized records: no credentials, cookies, personal data, production secrets or unrestricted logs. The included code runs locally and calls no model or provider. Network requests exist in one place only: the authorized check runner of S3 · AI Security Testing (L3 APPLY, also inside L4 SCALE) sends your inert checks to the one endpoint you name, by default a local stub, and refuses to send anything outside a valid authorization window and boundary. Instruction-like text inside your input is treated as data, and some workflows stop when they meet it. Security workflows also require written authorization for anything you test.

A purchase is a personal, non-transferable license for one person, and sharing the files needs written permission. When several people need a workflow, each person can have their own copy: email hello@nobrainer.tech with the series, the level and how many people, and we will reply with the options. If you would rather have a workflow built around your own process, see Custom Workflow On Demand for the details.
