Chapter 02 · The Build Path

From vague idea
to running agent.
In five stages.

Skip stage one or two and you join the 95 percent that fail. Do them in order and the odds flip hard the other way.

01 · The Funnel Method

Turn a fog into a first step.

Prompt 1 · Go wide
"I want to grow my brokerage. What are the highest-leverage moves this quarter?"
Prompt 2 · Break it down (the magic)
"List 10 concrete projects under that. Take #3 and break it into steps I can start today."
OK

The Mark Twain rule

Break the massive goal into steps, then do the first one. Most people skip prompt two and leave with vague advice. Prompt two is the work.

Pair it with four ingredients

1

Prompt

The question, narrow enough to be useful.

2

Context

Your docs, emails, goals. Upload it.

3

Intelligence

The expert choices. If unsure, ask the model what choices matter.

4

Outcome

What "good" looks like, measurable. "50% open rate."

02 · The five-stage path

Each stage turns on one capability.

1
Map

Write the decision logic. No tech.

So a stranger could run it without asking you a question. Do it with another person who asks "why." Skip this and nothing downstream works.

2
Test

Run the logic against a model.

Paste criteria + a real old input into Claude. Nothing connected. Does it apply your logic the way you would? Tighten, repeat.

3
Internal

Wire to safe internal tools.

Notes to task tracker. If it fails today, only you notice. Your sandbox. Watch it on messy real inputs for a week.

4
External

Go external, human in the loop.

Now it produces things clients see. It drafts; you approve. Most operators should plant their flag here for the long term.

5
Team

Add a second agent + memory.

Coordination and cross-session memory now matter. This is where a framework earns its place. Not before.

The whole map in one line

Stage 1 needs nothing. Stage 2 turns on model access. Stage 3 turns on tools. Stage 4 turns on oversight. Stage 5 turns on memory + coordination.

03 · A real workflow, four ways

Watch one job climb the levels.

Real use case

Client onboarding

The scenario: a client signs. Folders, welcome email, kickoff, project setup, intake chasing. 6 to 11 hours by hand, every single time. Here is the exact same job built at each level.

01
Auto

Trigger chain

Contract signed creates Drive folder, adds to CRM, pushes to Mailchimp. Silent break the day a field gets renamed.

02
Task

Personalized welcome email

Reads the call transcript, drafts an email that references the client's Q3 deadline. You send. Same quality Friday 4pm as Monday 9am.

03
Outcome

"Onboard this client."

Email drafted, project built, deadlines pulled from contract, kickoff slot suggested. You review one package. Most service businesses stop here.

04
Agentic

End to end, exceptions only

Pings you on the weird stuff. Danger: failures hide. A level-one break is loud. A level-four break is silent for three weeks.

The rule that saves you

Give an agent access only to what this workflow needs. Meta's AI safety lead gave one inbox access; it deleted the inbox. The AI worked fine. The way it was wired up did not.

04 · A real workflow, five steps

From messy inbox to handled.

Real use case

Inbound inquiry handling

The scenario: leads land in your inbox at random. A few are gold, most are not, all of them eat time. Here is the build, one safe step at a time.

STEP 1

Define "qualified"

Fields that matter, three buckets, criteria each. No tool yet.

STEP 2

Test in chat

Paste 5 old inquiries. Discover where your definition is implicit. Tighten.

STEP 3

Read-only inbox

Live inquiries scored and flagged. Nothing sends. Often enough on its own.

STEP 4

Add a drafter

Two agents: one sorts, one drafts. You approve before anything sends.

STEP 5

Open the safe gate

Auto-send polite declines. Qualified stays gated until 30+ are right.

THE LESSON

Build one step

Each step is its own decision. The one-step version already wins.

The handoff is the contract. If you cannot describe what one agent passes to the next in a sentence, the team is not designed yet. Skills hold both sides to it.
