How a PMM-of-one built an operating system , a permanent instruction set and a seven-agent stack , to ship better work than teams ten times the size. Taste stays human. Everything else scales. Proof shipped · Spry case below
AI is a taste amplifier, not a content factory. Default LLM output is the population mean of the internet. Left alone, it reverts to mush. The job is to starve it of defaults.
Taste is the scarce resource. Anyone can generate. Fewer can direct. One person making every call, seven agents executing downstream.
Constraints beat creativity. Better work comes from removing options, not adding them. The BAN FILE is what not to do. What's left is a narrow channel the model has to be interesting inside.
Most people prompt an LLM like they brief a freelancer , once, then hope. The freelancer has a resume. The LLM has nothing.
The BAN FILE fixes that. A permanent document , loaded into every agent , that codifies what my voice is, what it isn't, and what gets rejected on sight.
Forbidden words. "Leverage." "Unlock." "Game-changer." The full list of AI tells.
Banned frameworks. No three-point listicles. No "intro / body / conclusion."
Voice anchors. Sentence variance. Em-dashes with restraint. Concrete over abstract.
Every agent reads this file before it writes a word.
The same stack, 20+ hours of work, compressed into a week.
The sharp angle. What we're actually arguing.

Ask it why I'd pick HNI buyers over NRI investors. Ask it how I'd position Writesonic for the GEO shift. Ask it what's in the SPRY competitive landscape. It'll answer in my voice, with my receipts.
The speed gain is a trap. The real unlock is that you can now afford to reject the first eight drafts. Volume is free; taste is expensive. Spend the surplus on standards.
One narrow agent doing one narrow job, well, beats a mega-prompt trying to do everything. Split the work. Constrain each role. The seams are where quality comes from.
Models update. Tools churn. Agents come and go. The BAN FILE , the standard for what's good , is the only permanent asset. Portable across any stack. Outlasts every tool.
