Distill Your Own Collaboration Spec

A four-step flow comparison; three tasks: write your first Rule, walk a real requirement through the flow, export the Build Log and shape it into spec v1

THE QUESTION THIS PAGE ANSWERS

ANSWER FIRST

What is the key idea behind “Distill Your Own Collaboration Spec”?

A four-step flow comparison; three tasks: write your first Rule, walk a real requirement through the flow, export the Build Log and shape it into spec v1

DECISION RULE

Follow the handoffs, not the demo. A system becomes dependable at the boundaries between model, tools, state, permissions, and people. Read each handoff as a place where you can observe, test, and recover.

TRY NEXT

Name the input, owner, approval, and recovery action for one automated step.

WATCH FOR

A successful run that cannot explain what happened or be safely repeated.

Last square on the practice track: the thing is built. Now turn the process into a reusable asset.
M0
Know what you want it to do for you
M1
Talks like a human, reliably
M2
Actually gets work done
M3

The process is reproducible
See it first · Put the breakpoint before it starts working, and rework disappears

This chapter's four-step flow (restate, PRD, confirm, code) solves two faces of the same problem: the AI misunderstood the requirement and charged ahead anyway, and by the time you notice it has already changed twenty files. The breakpoint has to sit before it starts working. Any correction after that is rework.

Same requirement, two ways to hand it over

01
AI restates the requirement

In its own words, what it is supposed to do — if it's off, you see it on the spot

02
Write a PRD

The plan, the boundaries, what not to do — in black and white

03
Wait for your confirm

Human gate: no nod, no coding

04
Start coding

Only now does it start. What it writes is the thing you already confirmed

Understanding was already off. The faster it writes after that, the more it gets wrong
Toss one sentence and start writing. Step one already misunderstood it, but you only find out at acceptance. The faster and more diligent it writes, the bigger the unpermitted build you have to tear down. That is the mechanism behind "AI writes fast, so it wrecks things more easily."

You don't have to write rules from scratch

The xs_vibe_rules this chapter unpacks is something you can Fork directly. Just don't copy the whole set. A rule is valuable because a real crash sits behind it. A crash you never had — paste the rule and you still won't keep it. The right move: pick three to five rules from the pits you hit in the first five squares, then borrow from the repo the ones where you understand the "why."

Hands-on checklist · Pick one, start it, tick it off

This Chapter's Hands-on Checklist

0 / 3 done

Write your first Rule

15 min Everyone

From the first five squares, pick the pit that hurt the most and write it as a rule. Use the format this chapter taught: first the why (that crash), then the how (a concrete instruction). If format drift burned you at M1, the rule is "every output must match template XX; if it isn't in the materials, write 'not mentioned'."

What counts as done
After you put this rule at the start of a new conversation, that pit really stops showing up. If the rule is written but doesn't work, you wrote a wish, not an instruction.

Walk a real requirement through the four-step flow

1 hour Anyone who works with AI

Next real requirement, don't toss it straight to the AI. First ask it to restate; if the restate is off, correct it. Then have it write a one-page mini PRD. Only after you confirm do you let it go. Feel the whole thing: after you move the breakpoint forward, how much smaller is the gap between the result and what you expected.

What counts as done
The restate step catches at least one misunderstanding (if it doesn't, the requirement is too simple — pick a bigger one), and the final result needs no major rework.

Export the Build Log, shape it into spec v1

Half a day Anyone walking the full track

Go back to the Build Log, fill in all six milestones, export Markdown. Then the last step: shape it into your own AI collaboration spec: how you set requirements (M0), how you write prompts (M1), how you wire tools (M2), how you evaluate (M3), how you run long (M4), how the flow goes (M5). Send it to a colleague. See if they can build something similar from it.

What counts as done
If a colleague can ask specific questions about your spec, they actually read it. A "looks great" is usually a skip. At this point the whole track is done: you have an Agent that can work, and a method you can hand to someone else.

Back to the Build Log. Fill all six squares

M5 is the last square. Once all six milestones are filled, the export button gives you a complete Agent build dossier — the physical thing this course leaves in your hands.

Fill in M5 and export

How “See it first · Put the breakpoint before it starts working, and rework disappears” becomes executable

“This chapter's four-step flow (restate, PRD, confirm, code) solves two faces of the same problem: the AI misunderstood the requirement and charged ahead anyway, and by the time you…” is not about a magic phrase. It is about giving the model enough information to know who the work is for, what must be done, and what counts as acceptable.

Background sets direction; constraints set the boundary

“In its own words, what it is supposed to do — if it's off, you see it on the spot” shows why a useful request separates the task, audience, source material, output format, and constraints. Without background, the model guesses. Without acceptance criteria, fluent text is not evidence that the task is complete.

More words do not guarantee a better result

Turn “M5 is the last square.” into a small experiment: change only one of background, requirements, or constraints while keeping the rest fixed, then observe which layer actually changes the output.

From “See it first · Put the breakpoint before it starts working, and rework disappears” to “Hands-on checklist · Pick one, start it, tick it off”

“See it first · Put the breakpoint before it starts working, and rework disappears” grounds the problem in “This chapter's four-step flow (restate, PRD, confirm, code) solves two faces of the same problem: the AI misunderstood the requirement and charged ahead anyway, and by the time you notice it has already changed…”. “Hands-on checklist · Pick one, start it, tick it off” then moves it toward “From the first five squares, pick the pit that hurt the most and write it as a rule. Use the format this chapter taught: first the why (that crash), then the how (a concrete instruction) . If format drift burne…”. Together, they show that the lesson is not just a conclusion to remember, but a claim with conditions.

Carry the judgment into the next situation

Build a request layer by layer: task and audience first, material and output rules next, constraints and acceptance checks last. Change one layer at a time so you know what actually helped.

  • “See it first · Put the breakpoint before it starts working, and rework disappears”: This chapter's four-step flow (restate, PRD, confirm, code) solves two faces of the same problem: the AI misunderstood the requirement and charged ahead anyway, and by the time you notice it has already changed…

  • “The closing point”: Go back to the Build Log, fill in all six milestones, export Markdown. Then the last step: shape it into your own AI collaboration spec : how you set requirements (M0), how you write prompts (M1), how you wire…

The final “The closing point” brings the discussion to “Go back to the Build Log, fill in all six milestones, export Markdown. Then the last step: shape it into your own AI collaboration spec : how you set requirements (M0), how you write prompts (M1), how you wire…”. The useful thing to carry forward is knowing which judgments must be revisited when input, scale, or risk changes.

I turned one judgment from this article into a small experiment I could run today. Knowing what to observe next is more useful than simply remembering the conclusion.

After reading this, I first looked for the conditions behind the idea instead of copying the method into a project. That order made the later trade-offs much clearer.

When this judgment reaches real work, which constraint should be added first? I am curious which step matters most between reading and the first practical attempt.
