Map the ecosystem
Lay out everyone who matters—not just the immediate customer. Show who serves whom, who depends on whom, who benefits, and why every connection exists.
Uncle Dave’s pre-build rule
Figure out what the hell it is before you ask Codex to build it.
Codex is powerful. It is not clairvoyant. Give it the ecosystem, the commercial meaning, and the money path—and it can build from business reality instead of your first half-baked prompt.
No database cylinders. No architecture theater. Just boxes, connections, meaning, and money.

Get the business straight in three passes.
Don’t waste a week building something just because AI makes it easy to start. First give Codex the context most people forget.
Define the commercial meaning
Explain what each relationship accomplishes, what both parties contribute, who decides what, and what changes when the relationship works.
Follow the money
Show who pays whom, for what, under what terms, and where margins, commissions, referrals, and revenue shares live.
Don’t make yourself remember everything
Give Codex the project conversation too.
The point is not to sell you Slack. The point is to preserve the real conversation behind the build and make it available to Codex. If your team already uses Slack, connect the relevant project channel. If you have no shared running record, a dedicated Slack channel is one practical way to start one.
Your decisions, customer language, disagreements, changes, and unanswered questions become durable context instead of things somebody has to remember to type, speak, or explain all over again.
Ecosystem Map supplies the structure. Your team conversation supplies the memory. Together they bring Codex much closer to where your team actually is.
Then hand Codex something worth reading
Now Codex can see what you see.
The whiteboard does not hand over a flat screenshot. It prepares structured business context: named participants, defined relationships, stakeholder outcomes, economic flows, evidence, assumptions, and visible gaps.
Codex can use that context to ask the missing questions and write a specification based on how the business actually works.
Boy howdy, that produces a better first build than simply opening Codex and starting to talk.

Pre-build clarityUseful enough to begin
If you want another set of eyes
Talk it through with Uncle Dave.
Because this isn’t a framework he learned last Tuesday.
Dave has been starting and building companies since the mid-1980s—about fifteen of his own—and has helped plenty of other businesses through consulting along the way. He has spent four decades learning how customers, partners, products, incentives, and money either fit together or quietly sabotage one another.
This application is a recent example. While working on a Codex build one Sunday morning, Dave caught himself building before he had properly mapped the business. He looked for the right tool, couldn’t find it, and decided to build one.
About four hours later, the working whiteboard, website, and Codex plugin existed—and the next version was already being planned.
If your idea is still partly in your head, Dave can help you get the business straight before you spend time and money building the wrong thing.
Free, bro. Seriously.
Use the useful part without buying anything.
