The AI Ladder of Inference Coach skill for Claude
You put forward a conclusion you are already fairly certain of, and you get the reasoning underneath it back: seven rungs down from your intended action all the way to what was actually observed. To do this it follows the Ladder of Inference from Chris Argyris and Peter Senge: it names which data you left out, sets at least two alternative ladders next to yours on exactly the same facts, and gives you an intervention question per rung for the real conversation. Being told you are right because that reads more pleasantly is not part of the deal: if the data does not support your conclusion, it says so.

Assumption in, ladder out
reg. L.001This is the first example that appears in the SKILL.md itself, shown here in shortened form: the silent colleague. The input is a single sentence with a conclusion hidden inside it. Notice what the skill does: it notes the ladder from top to bottom, from the action you had already planned back to the facts, because that is the order in which you unravel a line of reasoning.
What the AI Ladder of Inference Coach is
The AI Ladder of Inference Coach is a free skill from our skill library. A skill is an instruction file, SKILL.md, that gives an AI assistant a fixed way of working for one task. What such a file actually is and why it works, you can read in what are Claude skills NL; this one is a 1,484 word text file that teaches Claude how to expose the reasoning underneath a conclusion using the Ladder of Inference. No software, no subscription, no account: you download the zip at the top of this page, put it in your Claude environment, and from that moment Claude breaks down every assumption you give it into seven testable rungs.
The problem the skill solves sits in a single word: must. He must be fed up with it. They must be going to a competitor. She must think it is not good enough. Sentences like this feel like observations, but they are conclusions, and that is exactly where the danger lies: the higher you stand on the ladder, the stronger it feels as if you are simply describing the facts, while you have already selected, interpreted and concluded. That belief is then followed by an action, a sharp email, a conversation that opens the wrong way, a deal you write off, and that action is sometimes harder to reverse than the thought was.
It is written for anyone who works with people: the team leader who has to give feedback, the salesperson interpreting a silent client, the colleague who feels a conflict coming, the coach who wants to help someone else reason things through. It is part of the library of 100 free skills we make available through the AI and automation service, with no account and no sales email afterwards.
One thing you should know beforehand: the skill does not tell you who is right, and it will not tell you that you are right just because that reads more pleasantly. Both rules are stated literally in the file. What you get is sharper: the point where your reasoning departs from the facts, and the question you can use to test that in the real conversation.
Why your own ladder deceives you
Argyris's model does not describe a rare thinking error but the normal way a brain works under time pressure. You cannot possibly process all the available data, so you select. You cannot store a selection neutrally, so you interpret. And on interpretations you build assumptions, conclusions and beliefs, usually in less than a second. Climbing itself is not the problem. The problem is that you do not notice you are climbing.
Add to that the reflexive loop, and that is what really sharpens the model. Your beliefs on rung 6 determine which data you select on rung 2 the next time round. Once you believe the colleague is fed up, you see new proof in every meeting: silent again, no reaction again. That the colleague simply does their work, nods and chats afterwards falls outside the selection. The ladder reinforces itself, and that is why two people can look at the same conversation and both be certain they are right.
In a work context that is costly. A team leader who lives on rung 6 gives feedback on their own interpretation instead of on behaviour. A salesperson who reads silence as rejection lowers a price nobody thought was too high. And a conflict between two colleagues is usually not a clash between two characters but between two ladders that are each correct within their own selection.
You can only interrupt that mechanism at one point, and that is where the skill steps in: it forces the reasoning back down. First name the intended action, then descend rung by rung until only the facts remain, and there ask the question: which data did I leave out, and where is the biggest jump? The file records this as a fixed action: it points out the transition between two rungs that has the least support underneath it.
In diff form, with lines from the second example in the skill: what the same thought looks like before and after descending.
Seven rungs, a hidden loop
reg. L.002This is the ladder as the SKILL.md describes it, from bottom to top. The figure lights up in the same order as the one in which you actually climb it: first the data, then the selection, and before you know it you are at the top. The highlighted rung is where, according to the model, things start to shift: selecting is already a choice.
What is really in the SKILL.md
A skill is only as good as its instructions, so here we simply describe them. The file opens with a frontmatter that states when Claude should pick up the skill. Not only for direct requests such as ladder of inference, inference ladder or check my reasoning, but just as much for the small sentences that hide a conclusion: I am assuming that, I take it that, he must have meant, they think that I, that is right, isn't it. Anyone who says something like that to Claude while the skill is loaded gets it automatically.
Next comes the method: seven fixed actions the skill carries out in every analysis. It first summarises the situation and presents that summary, so the analysis is about the right incident. It reconstructs the full ladder across all seven rungs, noted from rung 7 back to rung 1. It strictly separates what could actually be observed from what you selected out of it, and names which data was left out. It points out the biggest jump in the reasoning. It builds at least two alternative ladders on the same available data. It formulates an intervention question per rung. And it closes with a recommended action that comes before your planned action: what you check before you act on your current conclusion.
Before anything is analysed, the skill runs through a short mandatory input list of five points: what actually happened, as concretely as possible, the conclusion in your own words, what you intend to do, the relationship with the other person, and earlier incidents that play a role. It only asks about what is missing, in one go, and then carries on working with what is there.
The output always has the same six blocks, in the same order: your situation, the ladder across all seven rungs, the blind spots, the alternative ladders B and C, the intervention questions per rung, and the recommended action. The file also contains two fully worked out examples, the silent colleague from FIG.01 and the client who does not respond, and strict writing rules: businesslike, with no judgement of people, rungs always given with their number so you can refer back to them. If you want to learn yourself how to build such an instruction file, the full explanation is in writing SKILL.md NL.
Three ladders, the same facts
reg. L.003The sharpest part of the analysis is the counter proof: at least two alternative ladders on exactly the same available data. Not because your ladder has to be wrong, but because you only see that selection was a choice once someone puts a different selection next to yours. This is the second example from the SKILL.md, the client who does not respond to a quote.
The theory the skill rests on
The SKILL.md names four sources, and they are worth knowing, because the ladder is often retold in an oversimplified way while the original is more precise.
The model comes from Chris Argyris. The organisational psychologist described in Overcoming Organizational Defenses, from 1990, how professionals reason themselves into a corner: not through stupidity, but by climbing from observation to judgement at lightning speed and invisibly. His key point sits in the first two rungs: before you even interpret, you have already selected, and that selection does not feel like a choice.
Peter Senge made the model well known. In The Fifth Discipline, from 1990, in the chapter on mental models, he uses the ladder to show why teams talk past each other: everyone presents the top of their own ladder as fact. His remedy is the same as the skill's: make your reasoning open for discussion by showing it rung by rung, so someone else can respond to it instead of colliding with it.
The well known diagram comes from Rick Ross. In The Fifth Discipline Fieldbook, from 1994, he worked the ladder out into the drawing you see in almost every training course, with practical conversation questions alongside it. The skill's intervention questions stand in that tradition: not an accusation, but a question that opens up a specific rung.
With that, the ladder touches on a family of thinking tools that we also offer as a skill. Anyone who wants to learn to ask the questions themselves, instead of having them formulated, trains that with the Socratic Method Coach NL. And anyone who wants to know which other systematic thinking errors can creep into a reasoning process alongside the self reinforcing ladder can put the same case to the Cognitive Bias Detector.
Even without installing the skill you can use the model today: write down your conclusion, write underneath it what actually happened, and see how many rungs lie between them. Usually there are more than you thought.
What the skill refuses
reg. L.004The SKILL.md contains a list of seven things the skill never does, and for a tool that deals with conflicts and assumptions that list matters all the more. In conversation the rules play out like this: each rule is a request you might make, with the response the skill gives according to its own instructions.
Installing in Claude Code, Claude.ai or Codex
The zip contains one folder with the SKILL.md inside it. Installing is a matter of putting the file in the right place, and that place differs per environment. SKILL.md has been an open standard since December 2025, so the same skill also works in Codex, Cursor and Gemini CLI. So you are not downloading a Claude file but a working instruction that any modern AI assistant can read. The full guide per environment is in installing Claude skills NL.
- Unzip it into
~/.claude/skills/(or.claude/skills/in your project). - Claude then recognises the skill automatically as soon as you put an assumption or conclusion to it.
- You can also call it directly, with
/ai-ladder-of-inference-coach.
- Go to Customize and then Skills.
- Upload the zip there as a skill.
- Or paste the contents of SKILL.md into the project instructions of a Project.
- Open
AGENTS.mdin your repo. - Paste the contents of SKILL.md into it, or put SKILL.md next to it as a separate file and refer to it from
AGENTS.md. - Codex reads that along at every session.
After that, using it is simple: describe what happened and which conclusion you drew, as concretely as possible. Whatever is missing from its five point input list, it asks about itself, in one go, and then carries on working with what is there. If you are new to this kind of file and want to understand more broadly how working with AI works, you will find the wider explanation in the knowledge base.
When you do and do not use it
The file names six situations where the skill does its work. Conflicts in the workplace: understand your own reasoning before you say something. Client and sales conversations: test your assumptions about the deal before you act, as in the quote example above. Team leadership: give feedback based on data instead of interpretation. Difficult decisions: discover which beliefs have already limited your options before you started choosing. Coaching and one to one conversations: help someone else see their own leaps of thought. And personal development: recognise your own recurring patterns, because once you have seen your own loop turn a few times, you recognise it faster afterwards.
There are also limits, and the file draws them itself. This is not a substitute for the real conversation with the person it is about: the intervention questions are meant to be asked, not to skip the conversation. It gives no psychological or medical interpretation, not of you and not of the other person; if more than a reasoning question is at play, that belongs with someone qualified for it. And it does not start without a concrete situation: anyone who only supplies a feeling without who, what, where and when first gets asked for the facts.
The most honest limit is this: descending the ladder takes more time than climbing it, and that stays true even with a skill that does the groundwork. The analysis appears quickly, but the conversation in which you actually ask an intervention question is one you have to have yourself. What the skill changes is not that the difficult conversation disappears, but that you open it at rung 2 instead of at rung 6, and that makes exactly the difference between an accusation and a question.
Run it yourself, or have it run for you
reg. L.005This skill is the free do it yourself version of work we also deliver as a service. It is complete, and with no catches, but do realise what a skill is: it teaches your AI how to do something, while every new session starts empty. It is not the engine and it is not the memory. You prompt, you supply the context again every time, you check the result. Anyone who wants it differently has two follow up steps: hand over the engine, or arrange the memory.
where you are now The skill: you are the engine You run the AI Ladder of Inference Coach yourself in Claude, Codex or Cursor. It costs nothing, works today, and you keep it entirely in your own hands: no trial period, no locked features. The limit is your own time: it only happens when you prompt, and you have to supply the facts of each case again every session.
have it prepared for you The AI employee: it is ready without you having to prompt If you want this kind of work prepared every day without you having to sit behind Claude for it, there is the AI employee: a service where the work sits ready and a human keeps final control, because output stays a draft until someone gives approval. We deliver this through Mansotti, the company TheSEO trades as, which builds three fixed employees: the Quote employee, the Sales employee (prospect research) and the Reporting employee (weekly and monthly reports).
everything from one source Jarvis: all your AIs work from the same company knowledge The skill teaches the AI, the brain is where the memory lives. Want all your AIs to work from the same company knowledge? That is Jarvis, the organisation brain. It connects ChatGPT, Claude, Codex and your people to the same projects, core knowledge and decisions, so your next AI session does not start from scratch. For this model that matters even more: assumptions grow wherever facts are missing, and a brain that keeps the facts gives rung 1 a fixed place. What that delivers in practice, from the plans to your first week, you can read at Jarvis itself.
What Jarvis delivers in practice
reg. L.006Rung 3 deserves more than a paragraph, because this is the difference between a smart chat and a system you can build on. Jarvis is the organisation brain: it remembers what your AIs need to know, divides up the work and keeps track of what happened. For the ladder that is the logical foundation: assumptions arise where facts are missing, and a system that records agreements and events keeps rung 1 in stock.
We have been running on this system ourselves for months. Every agent session, every task and every decision gets logged in it and can be read back. So a new session does not start blank: it first retrieves the logged decisions, the running projects and the latest changes, and carries on from where the previous one stopped. So we are not describing a promise but the way of working we ourselves work in every day.

What does the AI Ladder of Inference Coach skill cost?
Nothing. The skill is free, falls under the MIT licence, and you do not need to create an account or leave an email address. You download a 4.2 KB zip containing one folder and a single file, SKILL.md, and that is the complete skill. There is no paid version and no sales email follows.
Does this skill also work in Codex, Cursor or Gemini CLI?
Yes. SKILL.md has been an open standard since December 2025, so the same file also works in Codex, Cursor, Gemini CLI and other tools that follow the standard. In Codex you unzip it into .agents/skills/ in your project, or into ~/.agents/skills/ for all your projects; Codex has supported SKILL.md directly since the open standard of December 2025. Putting the contents of SKILL.md into your AGENTS.md still works too. The instructions themselves are plain readable text, so any assistant that accepts instruction files can handle it.
What are the seven rungs of the Ladder of Inference?
From bottom to top: available data, selected data, added meaning, assumptions, conclusions, beliefs and actions. The skill records the ladder in reverse order, from rung 7 back to rung 1, because in practice you start with your intended action and have to reason backwards to the facts. The model also has a reflexive loop: your beliefs determine which data you select next time.
Does the skill tell you who is right in a conflict?
No, and that is a fixed rule in the file. The skill analyses the reasoning, not the conflict, and it will not tell you that you are right just because that reads more pleasantly. If the data does not support your conclusion, it says so. What you do get: the point where the biggest jump in your reasoning sits, and a question per rung to test that jump.
What is an intervention question?
A question that opens up a specific rung of the ladder in the real conversation. At rung 2, for example: are there situations in the past few weeks where he was active? At rung 4: what if silence could also mean concentration or trust? The skill formulates one per rung, so you can intervene at the point where your reasoning is weakest.
Can I also analyse someone else's reasoning?
Yes, that is one of the six use cases in the file: in coaching and one to one conversations the skill helps expose someone else's leaps of thought. The rules stay the same there: what that other person thinks remains an interpretation and not a fact, and the intervention questions are meant to be asked in the real conversation.
Is this therapy or a psychological test?
No. The skill gives no psychological or medical interpretation of you or of the other person, and that is listed as a refusal in the file. It is a reasoning tool: it shows where you jump from fact to interpretation. If more than a reasoning question is at play, the skill refers you to someone qualified for that.
Facts first, conclusions after
The ladder also applies to your own business. We are just not being found, this is not working for us: that is rung 5, not rung 1. You get the facts with the free SEO scan, which shows in a few seconds where your site stands. And if you want to talk further about what AI can do for your business beyond that, from separate skills to full automation, we simply do that in a conversation.
