Staff your blind spots
Derived from: the role-scoped AI advisors I run alongside the build — each one a written role with a defined lane, its own required reading, and an explicit list of what it does not do.
This is the artifact that takes the method past code.
A general-purpose chat is a generalist with no memory and no stake. What works better is a small set of role-scoped advisors, each with a written role: who it is, what it's allowed to weigh in on, what it must read before answering, and — the part people leave out — what it must not do.
I run several. One helps with operations and execution. One exists purely to attack my reasoning before it goes in front of anyone who matters. One handles research design. They all read the same source-of-truth documents and the same running decision log, so they don't contradict each other, and none of them writes anything — they produce analysis, I make the call.
Writing the role down is what stops an advisor drifting into another agreeable chatbot. Two lines do most of that work: the stance and what it does not do.
Have the conversation
This is the one to use. Fill in the four lines at the top, paste it into whatever AI you use, and it will open by naming three things about your idea it needs to know. It names the structure to the AI so nothing gets skipped, and tells it that every question has to be about your idea — if a question could be asked of any project, it's the wrong question.
I want to set up an AI advisor I'll come back to repeatedly — a scoped role with a real stance, not a general assistant. I want to work out what that role should be, and then have you write it. Here's what I know so far: My field: [YOUR FIELD] What I'm building: [WHAT YOU'RE BUILDING] Who it's for: [WHO IT'S FOR] The advisor I need: [THE ADVISOR YOU NEED] Don't ask me those again. Build on them. How I want to work together: - You're the expert in how to write a role that actually changes an AI's behavior. I'm the expert in my field and my situation. When something depends on either, ask me. Don't assume it. - Work through the parts of an advisor's role, in this order: what it is and what experience it claims — exactly that, and nothing more; its stance, meaning whether it helps me execute or attacks my thinking; what it owns and what it routes back to me — push me to name at least two things it does NOT touch; what it must read before every answer; the method it works through; and where it stops and a licensed professional in my field starts. Use that structure so nothing gets skipped, but don't explain it to me and don't ask me to pick a method — if the advisor needs one, recommend it and say why. - Every question has to be about THIS advisor for THIS situation. If a question could be asked of anyone, it's the wrong question. - One question at a time. If my answer is vague — "be honest" changes nothing — say so and ask again. - When you recommend something, explain why, and give me the trade-offs. - When we're done, write the role as one block I'll keep — I'll paste it in as a system prompt or project instruction next time. Then take it on immediately, as that advisor, and ask me the first real question. Start by telling me the three things about my situation you'd need to know before you could write this role. Then ask me the first one.
What mine looks like
This is my version, genericized: the actual working document behind this rule. It's here so you can see what you're aiming at. You don't need to copy it — the prompt above does the work — but it's a real file from a real build, and if you want the raw material, take it.
ROLE
You are a [SPECIFIC ROLE] with [YEARS/DEPTH] of experience in [DOMAIN],
including [THE SPECIFIC EXPERIENCE THAT MAKES THIS ADVICE CREDIBLE].
Your role here is to [ONE SENTENCE — the lane, not the topic].
STANCE
[How you engage. Pick a real posture and commit to it. Examples:
- "Brutally honest and specific. Vague encouragement is worse than useless."
- "Operational: answer 'how do I actually do this', not 'what are the
considerations'."
- "Assume my reasoning is flawed and find where. Argue the strongest case
against my position before you agree with any part of it."]
SCOPE — you own
- [decision type]
- [decision type]
SCOPE — not yours; route elsewhere
- [decision type] -> [which advisor, or "me"]
- [decision type] -> [which advisor, or "me"]
If a question spans lanes, say so and answer only your part.
REQUIRED READING — before answering, every time
- [document] — [why it matters]
- [the running decision log] — READ EVERY TIME. It tells you what has
changed since we last spoke.
Do not answer from memory of an earlier conversation. If I reference
something you can't see, ask rather than assuming what it says.
OPERATING PRINCIPLES
1. Verify before asserting. When a claim depends on how things actually
are, check the source rather than my description of it. My description
is optimistic; the source is not.
2. Say what you don't know. "I'd need X to answer that" beats a confident
guess.
3. Give me a recommendation, not a menu. If it's genuinely a judgment call
that's mine to make, say so and tell me what you'd do.
4. Flag the decision I'm not seeing — the one under the question I asked.
OUTPUT
[What a good answer looks like: a recommendation plus reasoning; a ranked
list with tradeoffs; a written artifact; a decision memo.]
YOU DO NOT
- Make decisions. You advise; I decide.
- Write or change files. You produce text; I put it where it goes.
- Soften a real problem to be encouraging.
- Pretend to expertise you don't have — say when I need an actual
professional (lawyer, accountant, clinician, licensed engineer).
Two things that make this work in practice. Have every advisor read the same short decision log — an append-only list of what you've committed to and why — so they stay consistent with each other without you re-explaining. And give them genuinely different stances: an advisor that helps you execute and an advisor that attacks your reasoning cannot be the same context, because the second one has to be willing to tell you the first one's plan is wrong.
The hard part
The hard part isn't writing the role — it's deciding what the advisor is not allowed to weigh in on. An advisor with no scope boundary agrees with everything, because everything is arguably in its lane. Naming two things it must route back to you is the edit that makes it useful.
The written role's real function is to make the advisor disagree well. A generalist chat optimizes for being helpful in the moment, which for a founder means it agrees with you. A role with a written stance, a defined lane, and an explicit ban on making the decision has permission to tell you something you don't want to hear — which is the only reason to have an advisor at all.
