Intent: the aim behind the moment.

Good assistance asks three things about an aim: how it was noticed, how settled it is, and at which level the person is speaking. An aim can last a moment or a year.

Intent

A good waiter does more than take an order. They notice whether you are still exploring, would welcome a suggestion, or are ready to choose. Intent is what someone wants to accomplish. Let’s see how an AI can notice that intention, without deciding it for them.

Two different questions

Imagine looking back and forth between two dishes. A waiter can see you comparing. But that does not mean you have chosen either one. There are two questions: how do we notice a possible need, and how far along is the person in deciding? A thoughtful offer is, “Would a comparison help?” Not, “I ordered that one for you.”

Four ways to notice

Context Grammar describes four ways an AI can notice an intention. Explicit: you ask. Active Implicit: your actions suggest a need. Passive Implicit: a familiar pattern offers a clue. And Ambient Implicit: the surrounding situation changes. These are ways of noticing, not four levels of permission. Let’s take them one at a time.

01 · Explicit

First, Explicit. You tell the waiter, “Something light, please. I need to leave in half an hour.” In an app, you might say, “Find my son some shoes for PE.” Speech, typing, and deliberate selections all give the assistant a direct request. But asking for suggestions is still different from authorizing a purchase.

02 · Active Implicit

Second, Active Implicit. You have not called the waiter, but keep switching between two dishes. The behavior offers a clue. Digitally, you might open the same size chart three times. The assistant can offer a side-by-side comparison. It should not assume that hesitation means consent, or that looking at a product means wanting to buy it.

03 · Passive Implicit

Third, Passive Implicit. At a regular family dinner, the host remembers that your family usually shares several small dishes. That familiar pattern can make a suggestion more useful. With information you have chosen to share, an AI might remember the meals your family enjoys. It can ask, “Your usual favorites, or something different tonight?” A habit is a starting point, not a fixed identity.

04 · Ambient Implicit

Fourth, Ambient Implicit. Something around you changes. The restaurant’s terrace closes as rain begins, so the host offers an indoor table. An AI might notice that a train delay affects a plan you shared. It can offer another route. The clue comes from the situation, not a new request from you. Moving your plans still depends on the permissions you set.

Noticing is not deciding

Now bring those clues into everyday life. Your child says their shoes feel tight. You might ask an AI assistant to find a pair, or start looking through size charts yourself. How does the AI realize you need help in the first place? And how far along are you in deciding what you actually want? Those are different questions: how it notices, and what stage your decision is in.

From a possibility to a decision

An intention can move through four stages. Latent: you have not yet considered a possibility. Exploratory: you are discovering what might work. Deliberating: you are comparing real options. Confirmed: you know what you want. Helpful support changes with each stage: a gentle invitation, room to explore, a clear comparison, then a confirmation of the action you choose.

A possibility you had not considered

A possibility can also bring people closer. A father loves the same manga as his children, but does not know the theme song from its anime. If the family has agreed to share those interests, an assistant could ask, “Would you like to hear the song they enjoy?” He says yes, and they listen together. The value is a new connection, not a prediction treated as a command.

Two questions, better support

Here is a simplified example of those two questions, not the full classification. Across: did you communicate directly, or did the AI observe a clue? Down: are you still deciding, or ready to act? A spoken request can be exploratory. An observed gesture can suggest readiness. Neither observation nor confidence grants permission. Keeping these questions separate helps the AI offer support without jumping to conclusions.

Notice. Ask. Understand together.

Back at your usual restaurant, you say, “Something different today.” The host does not bring your usual dish anyway. They ask what sounds good, then help you choose. AI should leave the same room to change your mind. An understanding you can correct is more useful than a prediction you cannot escape.

Keep exploring

Four ways to notice. Different stages of deciding. And always room for the person to guide what happens next. That is Intent. Read the Intent chapter for the full framework. Next, explore Situation Signals: how the same intention calls for different help as your body, surroundings, and available devices change.

A diner looks back and forth between two dishes while the host waits without taking an order.
Comparing is not choosing. A thoughtful host offers a comparison and never orders for you.

A familiar table

The attentive waiter

You sit down at a restaurant you know. You look between two dishes, close the menu, then open it again. The waiter notices, but does not decide for you. A short question about the sauce may help; a few quiet minutes may help more.

If you call the waiter and say, “Something light, please. I need to leave in half an hour,” your words give a clear direction. If you only pause over the menu, your behavior gives a clue. Neither clue, by itself, says that an order has been placed.

The digital parallel is familiar. Switching between two product tabs resembles looking between dishes. Asking for a comparison resembles asking about the sauce. Closing a menu can suggest readiness; even then, the waiter confirms the order. An assistant should do the same before a purchase.

The central distinction

Three questions, kept separate

1. How was it noticed?

The person said it, showed it through what they are doing, or the assistant inferred it from a routine or the surroundings. This is the detection channel.

2. How settled is it?

The person may have no particular idea yet, be exploring, be comparing, or be ready to choose. This is readiness, and a clue cannot settle it for them.

3. At which level is it spoken?

An outcome, a constraint, a task, or a single step. The assistant may work down the levels by itself; to go up, it asks.

Staring at the pasta is not an order for pasta. A product page view is not consent to buy.

Four ways a clue can arrive

These channels describe where the clue came from: said (Explicit), shown (Active Implicit), or inferred (Passive and Ambient Implicit). They do not rank how certain the person is or grant permission to act.

01

Said · Explicit

You say, type, or select a request.

02

Shown · Active Implicit

Your current action suggests a difficulty.

03

Inferred · Passive Implicit

A remembered routine offers background.

04

Inferred · Ambient Implicit

Time, place, or connected devices shape the moment.

Detection channels

Notice the clue; leave room for an answer

ChannelClueAt the table
Said · ExplicitYou say, type, or select a request.“What is in this sauce?” → answer the question.
Shown · Active ImplicitYour current action suggests a difficulty.You revisit two dishes → offer a comparison.
Inferred · Passive ImplicitA remembered routine offers background.You often choose a quick lunch → keep that option handy.
Inferred · Ambient ImplicitTime, place, or connected devices shape the moment.Little time before a meeting → keep the offer brief.

A routine can be wrong today. A pause can mean curiosity, uncertainty, or simply wanting time. The assistant can offer a small, dismissible aid and learn from the response.

Decision journey

How settled is the aim?

Readiness is a working interpretation, open to correction. The same channel can occur at any point in this journey.

ReadinessAt the tableHelpful digital response
Latent / UnexpressedYou have not considered a different dish.Offer a possibility as a question; let it pass.
Exploratory / DiscoveryYou read the menu to learn what is available.Show a few options and useful differences.
Deliberating / EvaluatingYou return to two dishes and ask about ingredients.Compare them side by side; keep the choice open.
Confirmed / ReadyYou name your choice and ask to order.Show the exact action and ask for approval when it commits.

A person can speak while still exploring: “What is this sauce?” is an explicit question, not a confirmed dinner choice. They can also appear ready without speaking: a closed menu is a useful cue, but the order still needs confirmation.

Levels of an aim

Outcome, constraints, tasks, steps

The same aim can be spoken at different heights. “A good dinner before the meeting” is an outcome. “Something light, out in thirty minutes” adds constraints. Choosing and ordering a dish are tasks; asking about the sauce is a step.

LevelAt the tableBuilding with AI
OutcomeA good dinner before the meeting.A slider I can keep maintaining on my own a year from now.
ConstraintsSomething light, within budget, out in thirty minutes.No new dependencies; keep the current design.
TasksChoose a dish and order it.Fix the slider.
StepsAsk what is in the sauce.Change the drag handler, then run the tests.

The assistant may move down the levels on its own: from “fix the slider” to the steps that do it. Moving up is different. Changing the outcome or loosening a constraint is the person’s call, so the assistant asks. And it never drags the person down into technical detail they did not ask to see.

Length does not decide what counts as Intent. Leaving in thirty minutes is an intent; so is keeping a codebase maintainable for a year. Both are read the same way: how they were noticed, how settled they are, and at which level they were spoken.

A compact reference

Spoken or observed × deciding or decided

This two-by-two view summarizes the story. It compresses four detection channels into spoken or observed cues, and four readiness stages into deciding or decided. It is a teaching aid, not a replacement for either full model.

Still decidingDecision formed
Spoken“What is in the sauce?” Answer; do not order.“I’ll have the pasta.” Confirm the order.
ObservedLooking between dishes. Offer a comparison or space.Menu closed. Ask if they are ready to order.

From insight to interface

Offer help at the scale of the decision

Explore

Give options the person can inspect and dismiss. A comparison tool helps without choosing a winner.

Evaluate

Show the basis for a suggestion and make correction easy. “The meeting is next week” should change the plan naturally.

Commit

Show the exact item, cost, recipient, and consequence. Research is not a purchase; a prepared order awaits approval unless a separate, bounded agreement permits that action.

For builders

Keep the architecture honest

The Coordinator can combine permitted knowledge from personal, household, and other relevant Brains into a tentative proposition. It should show what supports that proposition and where information is uncertain. Confidence describes the quality of an interpretation. It is not consent, and no confidence score alone authorizes a purchase.

The existing Intent model also names awareness_depth as Stated, Inferred, or Latent. Those labels ask whether an aim was expressed, interpreted, or not yet formed. The four readiness stages above ask how close a person is to a decision. They are related views, not interchangeable fields or a one-to-one mapping. A latent possibility is proposed and negotiated before anyone pursues it.

A good beginning makes room for the next question

Intent identifies the possible aim. Signals help the assistant read the present situation. Dials let the person decide what may be shared and what may be done. Together they let help arrive without taking the decision away.
