Before you ask what it takes
# What sets the size of a custom AI build
Five things decide it: the tools it connects, how much of the work it takes on, where it runs, how long it drafts beside your team before it runs alone, and the care it needs after. Your Blueprint names each one for your company, and the investment, in writing, before any work starts.
01 The five things
## What moves the size, and what keeps it smaller
### The tools it connects
Each tool the system reads or writes, such as your inbox, your books, your calendar, your CRM or a supplier portal, is a connection to build, test and keep working. A tool with a clean way in is quick. An old portal with no way in takes longer, because an agent has to work it the way a person would.
### How much of the work it takes on
Drafting replies for a person to send is a smaller build than answering on its own. Answering on its own needs the written rules, the log and the inspection period first.
### Where it runs
On outside services you approve, or on a private AI server in your office. The private server adds a machine to set up and look after, and keeps client data in the building.
### How long inspection runs
Nothing runs alone until it passes inspection on your real work. Varied, busy work takes longer to inspect than one steady kind of request.
### The care it needs after launch
Monitoring, tuning and fixes every month. A system that touches more tools, or acts alone more often, needs more of it.
02 What stays the same
## The rules come with every build, whatever its size
Every build ships with the eight rules in writing, an agent card for each agent, an off switch for each part, and a launch checklist. A smaller build does fewer jobs. It never skips a rule. [The eight rules](https://contractoros.tech/checklist).
03 Questions
## Asked and answered
#### How is a build priced?
Builds are five-figure engagements, scoped and priced in writing in your Blueprint before any work starts. The Blueprint is free.
#### Can we start small?
Yes. A Blueprint can name one piece to build first and the rest in order, so each part proves itself before the next one starts.
#### Is the Blueprint free?
Yes. One page, drawn for your company after a walkthrough, and yours to keep whatever you decide.
The Blueprint names the pieces, the order and the investment, on one page.
