Personal Harness Builder
Practicum for Chapter 6, "The Human as a System." Version: 2026-06-11. Time: 30 to 45 minutes. Use this after the Task-to-Outcome Map, once you know which tasks you are analyzing.
A harness is the system around AI that shapes the result. Chapter 6 describes six layers of personal usefulness and one practical layer called skills. Skills are repeatable ways of working that you do not need to explain to AI every time. This worksheet shows what your harness looks like today.
Faster in your browser: Use the Personal Harness Builder to score all seven layers and find the weak link and your next move.
Step 1. Inventory your week
Use three tasks from the Task-to-Outcome Map worksheet, or recall three typical tasks from last week. For each task, answer one question: Which AI tool did you use, and how did you use it?
| Task | Tool | How you used it |
|---|---|---|
An empty Tool column is a signal. It does not always mean there was no opportunity. It may mean there was no system.
Step 2. Score each layer
Score each layer of your harness from 1 to 3:
- 1 = missing or improvised each time
- 2 = present but inconsistent
- 3 = works as a system every time
Thinking: I think with AI without losing the skill
- Do I have a regular way to work with AI on hard tasks, beyond asking a question and copying the answer?
- Can I tell when AI is wrong and when it is right?
- Can I still complete important tasks without AI when I need to?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Knowledge: my personal knowledge base
- Do I have one place for useful materials, conclusions, and templates from earlier tasks?
- Can I give an AI tool the context for a new task in two minutes?
- Do I own my knowledge base, rather than leaving it in work systems I may lose access to?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Tools: tools with clear jobs
- Can I explain why I use each AI tool instead of another one?
- Do I have three to five basic tools with clear jobs, rather than 20 subscriptions "just in case"?
- Do I review my tool set once a quarter rather than every two weeks?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Proof: public work artifacts
- Do I have something public, such as an article, repository, case, presentation, or portfolio, that shows what I can do?
- Have I created artifacts during the past six months, rather than only completing internal tasks?
- Can someone outside my team judge my work from public material?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Trust: a reputation for quality and accuracy
- When I deliver work, do colleagues and customers trust that I checked the facts and data?
- Do I verify AI output before passing it to someone else?
- When people in my field need a reliable result, do they name me?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Outcome: a link to a real result
- Can I explain how my work affects a metric, a decision, or a customer, rather than only saying that I completed the task?
- In the past month, could I point to something and say, "This changed because of that work"?
- Do I track whether the person who requested the work uses what I made?
My score: ___ / 3
What I do now: ______________________________________________
What I want to improve: ______________________________________________
Skills: repeatable parts of the system
- Do I have at least one repeatable way of working with AI written as an instruction, rather than stored only in my head?
- After a task repeats three times, do I turn it into a template, checklist, or
skill? - Do my skills set boundaries where AI must stop and ask a human?
My score: ___ / 3
Step 3. Read your scores
Put all your scores in one place:
| Layer | Score |
|---|---|
| Thinking | /3 |
| Knowledge | /3 |
| Tools | /3 |
| Proof | /3 |
| Trust | /3 |
| Outcome | /3 |
| Skills | /3 |
| Total | /21 |
Find the weakest layer, with a score of 1 or 2.
A harness is a system, and one weak link can limit the rest. Improving three layers together usually works better than polishing one layer that is already strong.
My priority layer: ______________________________________________
Step 4. One specific move for the next two weeks
Write a concrete action, not "improve Knowledge."
Too vague: "Create a knowledge base."
Specific: "By Friday, create one folder in Notion or Obsidian for conclusions from work meetings."
Too vague: "Get better at verifying AI."
Specific: "For every report I send to my manager, check the three main numbers by hand."
Too vague: "Make some skills for myself."
Specific: "Write one skill for the weekly report: inputs, steps, checks, and the point where AI must stop."
My one move for the next two weeks:
______________________________________________
______________________________________________
Date I will check the result: ____________
Connection to the Task-to-Outcome Map
If you completed the Task-to-Outcome Map first, look at question 4, "Where is a human needed?" Your weakest harness layer may sit exactly where you identified the human's most important role. That makes sense. Trust and Thinking grow through regular practice, not through buying tools.
