A list produces the scenarios on +the list and stops, and the ceiling is then ours rather than the agent's. + +## What makes a scenario worth having + +**It can fail.** If the agent cannot plausibly get it wrong, it is a demonstration, not a test. +The interesting ones sit where the agent must choose: two readings of the same request, a +precondition it should check and might not, a state that makes the obvious action wrong. + +**It fails for one reason.** When a scenario can fail three ways, a red result tells you nothing. +Vary one thing against a background you control. + +**The person behaves like a person.** They change their mind, arrive with the wrong information, +answer a different question, go quiet. A caller who recites exactly what the agent needs, in +order, is testing nothing but the happy path. This is where scripted-sounding suites come from, +and it is the most common way a large suite turns out worthless. + +**The caller does not know the agent's rules, so never write them into the instruction.** Giving +the caller the expected agent behaviour and telling them to accept it is the most common way a +scenario stops testing anything: a compliant agent and a lucky one then look identical. Write what +the person wants and how hard they will push for it, and let the agent's behaviour be the thing +under test. + +> Not: "if the assistant says card details cannot be read aloud, agree to receive a payment link." +> +> Instead: "you would rather just read the number out. If refused, you are mildly annoyed but you +> will use another method." + +The caller also does not know they are in a test. An instruction that says "see whether the +assistant will refuse" breaks the frame and belongs in what the scenario claims to test, not in +what the person is told. + +**It is grounded in this agent's world.** Real record ids, real balances, real prices. An invented +id fails the first gate; a plausible-but-absent one produces a test of error handling you did not +mean to write. + +**It is not another dressing of one you already have.** The same test with a different name is +worse than nothing: it inflates the count and hides the gap it should have shown. + +**Name it for what it tests, never for who called.** The folder name is how a failure gets read +weeks later, so it has to say which behaviour broke: name it for the rule or the step that failed, +never for the person who called. A caller's name in the folder name is a sign the caller was +carrying the difference the test should have been carrying. + +**Who the caller is is not a lever.** A different name, job or city is the same test in a different +costume. What can change a result is the caller's situation and how they behave: what they are +entitled to, what they can prove, what they already have, whether they are calm or in a hurry, +cooperative or withholding, consistent or contradicting themselves. Vary those, and let the name +follow. Two scenarios that differ only in who is speaking are one scenario. + +## Write the check that would catch the failure + +A scenario is only as good as the thing that decides whether it passed. The usual failure is +quiet: the check asserts that a step *happened*, while the rule being tested is about *order* or +*values*. Then an agent that did the wrong thing in the wrong order still passes, and the suite +reports green while testing almost nothing. + +A check is `def check(world, calls)` returning `None` to pass or a sentence saying what was wrong. +Each call carries its name, its arguments, its result, whether it succeeded and when it happened, and the list is in order. So order +and values are both available. Use them. + +**If the rule says "before", assert the order.** "Verify before charging", "quote the fee before +committing", "read the total back before taking payment". + +This is the one most often got wrong, and the wrong version looks right. A check that gathers two +calls and asserts each happened is testing occurrence, and an agent that did them in the forbidden +order passes it: + +```python +# WRONG for an ordering rule: passes even when the card was charged first +def check(world, calls): + if not [c for c in calls if c.name == "send_otp" and c.ok]: + return "send_otp was not called" + if not [c for c in calls if c.name == "verify_otp" and c.ok]: + return "verify_otp was not called" + return None +``` + +If your check never compares two positions, it cannot be testing an order. Compare them: + +```python +def check(world, calls): + ok = [c for c in calls if c.ok] + verified = next((i for i, c in enumerate(ok) if c.name == "verify_otp"), None) + charged = next((i for i, c in enumerate(ok) if c.name == "select_payment_method"), None) + if charged is None: + return "no payment method was selected" + if verified is None or verified > charged: + return "selected the payment method before verifying" + return None +``` + +**If the scenario names a value, assert the value.** A destination, a tier, an amount, a code. A +check that only asks whether the tool was called cannot tell the right answer from the wrong one, +which is the whole point of naming it. + +**If the scenario is about a refusal, assert the refusal.** This is where suites are weakest, +because "nothing bad happened" is easy to leave unwritten. Two ways, and prefer the first: + +- **Positively**, by asserting what should have happened instead. An agent that granted the + request would not also have transferred to a human or asked for the real code. +- **By absence**, when there is no such trace: assert the forbidden call did not happen, or + happened without the injected argument. + +An adversarial scenario whose checks only cover the steps taken on the way in is decorative. If +the agent could comply with the attack and still pass, the check is not testing the scenario. + +**Look at the world, not only at the calls.** The world was built, seeded and frozen so it can be +inspected afterwards. `world.state()` tells you whether the record exists, whether the status +really changed, whether the balance moved. A call having been made is not the same as the world +having changed. + +**Refine a catalogue sub-goal when the scenario deserves it.** The shared catalogue is what makes +results roll up across a suite, so keep using it. Where a scenario asserts something of its own, +add a check of its own beside it rather than leaving the generic one to stand for both. + +**Some rules cannot be settled by code**, tone, turn length, saying one thing at a time. Those +belong to a judged sub-goal that names the rule. Do not fold them into a catch-all, and do not +pretend a coded check covers them. + +## Planning, when the count is more than a couple of dozen + +Decide what every scenario is, one line each, before any of them is written. + +`show_grid` gives the space to cover, derived from tool names and a data schema. Check it against +the source and correct it with `set_objects` first: if it missed an object, split one in two, or +turned an action into a thing, everything planned on top inherits that. + +`plan_suite` proposes an arithmetic spread across the grid. Treat it as a suggestion. It cannot +know which cells are dangerous in practice, where real users spend their time, or which operation +you have just read and know to be fragile. Take what fits, drop what does not, add what it missed. + +**Then `record_canvas`, because a plan you did not record does not exist.** It is the ledger every +later step reads: which buckets are filled, what a writer may claim, what coverage is measured +against, and what a stopped run resumes from. Skipping it is the easiest mistake here and the most +expensive. `show_canvas` reads it back a theme at a time. + +A good plan is made of buckets that differ in *kind*, not in wording. If two buckets would be +briefed with the same sentence, they are one bucket. + +## Briefing writers, which is most of what you do + +`claim_slice` takes the next angles and marks them claimed so nothing is written twice. +`fold_return` takes back what a writer covered and reopens what it did not, one entry per angle +with its own count and a sentence on what was actually covered. A writer that returns nothing must +reopen its slice rather than silently consume it. + +**Writers run at the same time, up to ten of them, and ten is the most there may be.** Brief them +together rather than waiting for one to finish before starting the next, and keep that many +working whenever the canvas has that much open. Use fewer only when the buckets left would +overlap, or when writers come back empty or refused, in which case find out why before claiming +more. + +The quality of a slice is decided by its brief. A writer sees the coordinates you name and little +else, so: + +- **Name the cells verbatim.** A writer that has to guess its scope writes something adjacent. +- **Say what the angle is for**, not just what it is called. "Caller gives an address that matches + two saved places" produces a better test than "ambiguous address". +- **Hand it the callers**, a name, an accent and a location per scenario, distinct across the whole + suite. Left to choose, every writer picks the same few names and the suite reads as one voice. +- **Say what has already been written nearby**, so it does not rediscover a scenario a sibling + just wrote. +- **Ask for the scenario names back per bucket.** That is what `fold_return` checks against disk, + and it is how you catch a writer that reported more than it produced. + +## Proving, and what a refusal means + +A gate that refuses is information, not an obstacle. Use `inspect_world` so a scenario names +records that exist, and `try_calls` to work out the reference solution before submitting. If a +proof reports a check is vacuous or broken, repair that sub-goal with `add_sub_goal` and resubmit. + +Never evade a gate by deleting a check for behaviour the scenario still claims to test. A suite +that reports every gate green while holding scenarios whose solution never touched the world is +worse than a smaller honest one. + +`save_scenarios` folds the journal into folders. A delegated writer journals rather than writing +folders, so anything asking what exists must read both. + +## Finishing + +`show_coverage` against the grid, so what was left untested is on the record rather than implied by +a count. `show_diversity` shows how the saved suite spreads and names any pair that reads as the +same test twice. `expand_suite` copies proved scenarios across caller conditions that do not change +the world, when more of the same situation under different people is what is wanted. + +## Meet the number, or say why not + +Give as much of what was asked for as genuinely exists, and work for it. If the agent really has +that many distinct things worth testing, find them. + +If it does not, say so plainly and say what you exhausted. A suite padded to a requested number +with the same tests under different names looks like coverage and is not, and it is worse than the +honest smaller number because it hides the gap it should have shown. + +This is a last resort, not an opening position.

Name that instead. + +A plan will be rejected if any axis is a list of names. + +--- + +## Step 3. Choose the cells worth covering + +Call `show_grid`. It lists every coordinate: an operation applied to an object. + +For each cell, ask what could make the agent get it wrong. Some cells have several distinct +difficulties. Some have one. Some have none, and should be left with no bucket rather than filled +for the sake of it. + +If the grid is missing something the agent plainly does, correct it with `set_objects`. + +**The grid cannot show you order.** A cell names an operation on an object; it says nothing about +what must have happened first. So work through the tools that refuse until something else has +happened, and give each one a bucket for being asked too early. Name the tool in `why_hard`, as +`precondition:`. These are among the most valuable tests there are, and they are invisible +in any count of cells. + +--- + +## Step 4. Write the buckets + +One bucket is **one cell plus one kind of difficulty**. + +Give each bucket: + +**`id`** — a short label of your choosing. Never reuse one. Never rename one. + +**`theme`** — which group it belongs to. + +**`cell`** — the coordinate from the grid. + +**`angle`** — a sentence describing the case, written so that somebody who has never seen this +agent understands what is being tested. Two things have to be in it: + +- what the person is trying to achieve +- what makes it hard + +Write it from the person's side, as something they want, not as a label for a feature. "greeted by +name" is a label and tells a reader nothing. "a returning user expects to be recognised from their +number, and the record it matches is not the one they are calling about" is a case. + +**The difficulty has to be in the sentence.** If you can describe the bucket without saying what +could go wrong, you have described the ordinary flow, not a case worth testing. "a person asks for +the usual thing and gets it" is not a bucket. Every bucket exists because something about it is +hard: name that thing. + +The ordinary path is worth one bucket, and only one. Everything else in the plan should be a way +it can go wrong. + +One or two sentences. If you are writing a third, you are describing how the case unfolds, which +is the test rather than the plan. + +**`why_hard`** — which kind of difficulty, using exactly one of these five prefixes: + + rule: a constraint the agent must obey + precondition: something that must have happened first + data: a state the data can be in + ambiguity: a request with more than one reasonable reading + boundary: a value at a limit + +What follows the colon is yours, and describes this agent. + +**`expects`** — what the agent should do, exactly one of: + + succeed it completes the task + refuse it must not do this + ask it must clarify before acting + escalate it hands off to a person + +**`overlay`** — only if something is deliberately making it hard. One of `impersonation`, +`injection`, `fraud`, `emergency`, `pressure`. Otherwise leave it empty. + +`expects` and `overlay` answer different questions. Something designed to manipulate the agent +*expects a refusal* and *carries an overlay*. Record both; do not choose between them. + +--- + +## Step 5. Decide how many tests each bucket holds + +**`want`** is the number of tests in the bucket. Work it out; do not pick it. + +1. Ask which state axes change the answer **for this bucket specifically**. List them in + **`varies_by`**. Usually one, sometimes two, rarely more. + + Every value of an axis you name has to make sense for this bucket. If an axis has a value that + contradicts the bucket's own description, that axis does not apply here and you are inflating + the count with combinations that cannot exist. +2. Multiply the number of values those axes have. That is the ceiling. +3. Remove combinations that cannot happen in this world. +4. Remove combinations where the agent should do exactly the same thing. +5. What is left is `want`. + +If a bucket holds more than one test it **must** name its axes. There is no way to justify a count +in words: a sentence cannot be checked, and every count in this plan has to be checkable. + +`want` can never exceed the ceiling from step 2. If you want more tests than the axes allow, either +there is an axis you have not named, or the extra tests do not exist. + +Expect buckets to be very uneven. Some cross two axes and hold many tests. Many hold exactly one, +because the agent does one thing regardless of everything else. **That unevenness is correct.** + +Two signs the sizing has gone wrong: + +- every bucket holds one test → you listed tests instead of grouping them +- every bucket holds the same number → you padded to reach a target + +## Step 6. Record it, one theme at a time + +Call `record_canvas` with the first theme's buckets. Then call it again with the next theme's. Each +call adds to the plan; it does not replace it. Pass `target` on the first call. + +Do not try to record the whole plan in one call. Each call is checked as it arrives and saved +immediately, so a reply that runs long costs you one theme instead of everything. + +If a call is rejected, it will say exactly what is wrong. Fix it and record again. This loop is +cheap. Anything wrong left in the plan costs a whole test later. + +--- + +## Before you record, check your own work + +Go through the plan and confirm all of these: + +1. No axis is a list of names, identifiers, or specific records. +2. Every bucket holding more than one test names the axes that make those tests differ. +3. No bucket asks for more tests than its axes allow. +4. The plan touches most of the grid, not a few cells deeply. A suite that goes eight deep on + twenty cells and ignores forty others has left most of the agent untested. +5. Every rule the agent must obey has at least one bucket testing it. +6. Every tool that refuses until something else has happened has a bucket for being asked too + early. +7. The plan contains buckets where the agent should refuse, where it should ask, and where it + should escalate. Not only ones where it succeeds. +8. Every angle reads as a case somebody could actually meet, and would make sense to a reader + who has never seen this agent. + +--- + +## What will be refused, and why + +`record_canvas` rejects the whole instalment and tells you which rule you broke. These are all of +them: + +- **two buckets share an id** — progress is tracked against ids, so a repeat loses history +- **a bucket names a theme you did not declare** — nothing can group it +- **a bucket names a cell that is not on the grid** — nothing can count it +- **a bucket is labelled rather than described** — a reader cannot tell what is being tested +- **a bucket is written as a whole script** — that is the test, not the plan +- **a bucket names a state axis you did not derive** — nothing can check the count +- **a bucket expects something outside succeed, refuse, ask, escalate** +- **a bucket names an overlay outside the five listed** +- **an axis is a list of names rather than states** — the agent behaves the same for all of them +- **a bucket holds more than one test without naming its axes** — the count cannot be checked +- **a bucket holds more tests than its axes allow** — the extra tests do not exist +- **the plan has nearly as many buckets as tests** — that is a list, not a plan +- **a large plan touches only a small part of the grid** — deep in a few places, absent everywhere else +- **a large plan names none of the tools that refuse until something else has happened** — being asked too early is a case the agent can fail and the grid cannot show + +Fix and record again. This loop is cheap. Anything left wrong here costs a whole test later. + +## What you must not do + +- Do not write the tests themselves. +- Do not describe how a case unfolds. Name what it is. +- Do not count different names, wordings, or personalities as different tests. If the agent should + respond the same way, it is one test. +- Do not raise a count to reach the number you were asked for. +- Do not invent a state the world cannot reach. + +--- + +## If the agent does not have as many cases as you were asked for + +Aim at the number. Read the source again before concluding it is exhausted, because a second +reading usually finds cases the first missed. + +If it genuinely does not have that many distinct cases, stop and say so, naming what you covered +and what you exhausted.

Pass the column, not the +value: `by="id"`, `by="market"`, `by="phone"`. + +**Prefer creating over editing, and understand why.** Editing a row the agent's seed data happens to +contain makes this scenario depend on state it does not own: a sibling editing the same row is +testing the same thing, and if the seed ever changes this scenario quietly stops testing what it was +written for. A scenario that creates its own record cannot be undermined either way. Edit only where +the condition is genuinely a property of an existing record, and then assert it in the readiness +check so the dependency is explicit rather than assumed. + +A setup that only edits is leaning on the base world and will be refused. Create what the scenario +is about. + +Use `inspect_world` to read the schema and see which column each collection is keyed on, and what a +real row looks like. Copy the shape, not the row. + +## Write the instruction to the person, carefully + +For a conversational agent the instruction is not addressed to the agent at all. It is what the +simulated person wants, in their own terms. It is the highest-leverage field in the scenario, because +everything the scenario tests reaches the call through it. + +**Give them everything they know, not only what the happy path needs.** The agent will ask things +the script did not anticipate: another address on file, when the last one was, which of two cards, +what the reference number was. A person who has no answer to those either invents one, which +poisons the run, or stalls, which ends it. So write down the facts this person plausibly holds: +their own details, the values in play, the history behind the request, and what they would say if +pressed on any of it. Then mark in `withheld` the ones they will not volunteer until asked. + +That is the difference between a person and a script. A script answers what it was written for; a +person answers what they are asked. + +Say, in their words: + +| Say | Do not say | +|---|---| +| what they want, concretely, with the real values | what a correct agent should do about it | +| every fact they hold, whether or not the expected path needs it | the rubric, or the pass condition | +| what they will not volunteer until asked | how the conversation ends | +| how hard they push, and what makes them stop | that the assistant will refuse | + +The moment the instruction says what the agent does, the transcript reads correct whether the agent +was or not, and the scenario grades nothing. + +### Give the goal, never the route + +Write what this person is trying to achieve and what they know. Do not write their side of a +conversation that has not happened yet. + +An instruction that reads *"if asked to confirm the address, confirm that 1200 Guerrero Street is +correct; if offered options, ask for the standard one"* has two faults at once. It names the route +the agent is expected to take, so the scenario stops testing whether the agent takes it. And it +leaves the person with nothing to say the moment the agent does something else, which is most of the +time, because a probabilistic agent reaches the same end by different routes. + +Write the fact, not the reaction. *"Home is 1200 Guerrero Street. You want the cheapest standard +option."* Now any question about the address or the option has an answer, in any order, however the +agent asks it. + +### The person's own data belongs in the instruction + +List what this person would actually have to hand, because the agent will ask for things the +expected path never mentions. + +| Give them | So that | +|---|---| +| their own contact details, exactly as the world holds them | an identity check can succeed or fail for the right reason | +| the identifiers they would plausibly know: a reference, the last digits of a card, an account label | a lookup is not blocked by a person who simply has no answer | +| the history behind the request: what happened, roughly when, what they were told | a question about the past does not stall the call | +| what they would say if pressed on any of it | the call survives a route nobody planned | + +A person with no answer to an unplanned question does one of two things, and both destroy the run: +they invent a value, which cannot match any record, or they stall, which ends the call early. Neither +is a finding about the agent. + +**Worked example.** The vocabulary below is illustrative only: use your agent's own objects, fields +and values, never these. + +Too thin, and it reads as passing while testing almost nothing: + +> You are Ana. Renew the membership on your account. Give code 481920 when asked. + +It names no record the agent can look up, so an identity check has nothing to work with; it scripts +one reaction and nothing else, so any other question stalls; and it says what to do rather than what +this person wants. + +Written to the standard: + +> You are Ana Ferreira, calling about the membership on your own account. You want it renewed for +> another year on the card already on file, and you want to know the cost before anything is charged. +> You know the account is under this phone number, the card on file ends 3318, and that you last +> renewed about a year ago after being told it was the final year at the old rate. You do not +> remember the account number and will say so if asked. You will not agree to a renewal until the +> price is stated, and if it is higher than last year you want to know why before deciding. + +The second names the values a lookup needs, holds facts for questions nobody planned, states a goal +rather than a route, and gives the person a condition that makes them push back. It is longer because +it carries more, not because length is the point. + +Then mark in `withheld` the facts they will not volunteer until asked. That is what forces the agent +to elicit rather than receive. + +### Realistic values, always + +Everything this person says or knows has to look like production data, because a scenario built on +obviously fake values tests a conversation nobody will ever have. + +- Phone numbers that read as real numbers in the right region, never a sequence of digits. +- Names, addresses and places that exist or plausibly could, with the detail a real one carries. +- Codes, references and identifiers with the shape the real system uses, not `1234` or a run of + repeated digits. +- Amounts and balances at the awkward values the scenario needs, not round demo figures. + +The same applies to everything the setup writes into the world.

Decide how it ends before writing the checks, because +the checks have to agree with it. + +A scenario ending in a refusal or a handover to a human +must not also require a transaction to finish after that transfer. +Those outcomes are mutually exclusive, so whichever the agent does, the other checks fail it and no +correct agent can pass. + +If both halves are worth testing, split them into two separate scenarios rather than one scenario +with two endings. + +## Two scenarios differ only when the right answer differs + +Before submitting, compare against what exists: **name an agent that passes that one and fails this +one.** If you cannot, it is the same test twice. + +Changing who is calling is never the difference.

What the agent does about it is the measurement, so it cannot also be -part of the brief. - -**The test that catches all of it: could this person say the sentence out loud?** The instruction -is read by someone who has never seen the agent's design and does not know how it works. So a -parenthetical explaining where the agent is supposed to find a value is not a smaller version of -the mistake, it is the same mistake in a quieter voice. - -``` -BAD Your : (the agent should find this from your ) - (the caller has no idea the agent has records, let alone which one. The note is - written for whoever reads the scenario, not for the person on the call, and it - tells them the mechanism that is being tested) - -GOOD Your is the same one you used last time. You do not remember the - exact address and would rather not look it up. - (now the caller has a reason to expect the agent to know, which is what makes - the agent's lookup worth testing, without being told the lookup exists) -``` - -Pre-agreeing to something the agent has not done yet is the most damaging form. "You have already - that the agent will " hands the agent a pass: the person confirms it -whether or not it happened. Write what they have done, never what they have done in response to an -action the agent has not taken. - -**Steps that happen outside the conversation need a state, not a response.** Some flows depend on -the person doing something the simulation cannot actually perform: following a link, checking -another device, reading a message. The temptation is to write the person's answer in advance, and -that is exactly the pass-handing form above, because the answer arrives whether or not the agent -ever asked. - -Give them a standing disposition instead, and let the agent's action trigger it: - -``` -BAD The agent will send you . Tell them you have - completed it when asked. - (the scenario is testing whether the agent sends it. This person confirms - completing it even in a run where nothing was ever sent) - -GOOD You have your with you and you are willing to follow anything you - are sent. You have not been sent anything yet. - (a state. If the agent sends it, this person can act on it and say so - truthfully. If the agent never does, they have nothing to confirm, and the - transcript shows the difference) -``` - -The closing sentence matters: stating what has **not** happened yet is what stops the person -assuming it has. - -Only write such a step when the agent can observe it completing. The person can say they did the -thing, but saying it changes nothing the agent reads. If the agent confirms progress by checking -state, that state has to be something the world moves once the person acts. Where it cannot, the -agent is left polling something that never changes and the scenario measures the world's gap -rather than the agent, so choose an outcome the agent can reach through its own actions. - -The same holds for anything the agent can only offer. A check that passes only once the person -accepts an optional courtesy needs that willingness written into the person, because the agent can -raise the offer but cannot make them take it. A person left free to decline turns a correctly -offered step into a failed check, and the run then scores the disposition the persona happened to -be given rather than the agent's behaviour. Either give the person a reason to accept, or check -that the agent made the offer rather than what followed it. - -**Use persona deliberately.** An accent, personality or characteristic belongs in `persona` only -when it changes the conversational risk being exercised. A rude customer is a different scenario -from a polite one only if the agent must handle that difference. Persona never contains the -answer, hidden checks or values the person has not been given. Every conversational scenario must -supply one when the simulator prompt asks for `{{ persona }}`. Before submitting, fill its -required profile: `name`, `personality`, `communication_style`, `languages`, `accent`, and at -least one `keywords` entry. The harness rejects an incomplete persona rather than quietly generating a -generic caller. - -## Writing setup, and the mistake to avoid - -**Whatever the instruction presumes about the world, setup has to make true.** This is where -scenarios most often go wrong: the instruction says the person is returning an order that has -already shipped, and setup leaves every order pending, so the agent refuses correctly and the -scenario fails it for being right. - -The rule: read your own instruction back, list every condition it assumes, and make sure `setup_code` -establishes each one and `ready_code` proves it. An empty `setup_code` is only honest when the base world -already holds everything the instruction presumes. - -## Two scenarios are different only if the right answer differs - -Not if the wording differs. "The item is in stock" and "the item is out of stock" are two -scenarios, because the correct outcome is different. Two polite requests for the same thing are -one scenario written twice. - -Changing who calls, where they are going, or which tier they pick does **not** make a second -scenario. The agent does the same things in the same order and the same checks decide the result; -all that changed is the noun. Ten of those look like coverage in a list and are one test. - -**A count you were given is a ceiling, not a quota.** If the agent's real branches run out at -twelve, submit twelve and say why. Padding to reach a number buys rows that can never fail -independently, and it hides the branches nobody wrote behind a suite that looks thorough. An even -spread across every use case is a warning sign, not a goal: real agents have use cases worth five -scenarios and use cases worth one. - -## One scenario must have one coherent terminal outcome - -Do not combine branches whose correct outcomes stop one another. A scenario that asks the agent to -transfer an out-of-scope request must not also require a transaction to finish after that transfer; -a scenario that correctly refuses, escalates, cancels, or ends the conversation must not carry a -sub-goal for work that only happens when the conversation continues. Provider web calls may record -an attempted phone transfer without being able to complete the PSTN handoff, so test the offer or -attempt in that scenario and test the transaction in a separate scenario. - -Before keeping a scenario, read its instruction, solution, and every named sub-goal as a single -path. If satisfying one sub-goal can correctly prevent another from being reached, split them into -separate scenarios. Never add an unrelated transactional sub-goal merely to make every scenario -exercise a tool. - -## The bar every scenario has to clear - -- **A competent agent could plausibly fail it.** If any correct implementation passes for free, it - teaches nothing. Do not write it. -- **A real person could plausibly bring this situation.** Nothing contrived. -- **Every concrete value is real**, taken from the contract or the world. An invented id or menu - item makes the test worthless whatever else it does. -- **Check the path, not only the outcome.** Where the right answer depends on something the agent - has to find out first, the sub-goals cover that too. A scenario whose solution is the single - terminal call passes for an agent that jumps straight there, having established nothing. - -``` -BAD solution [transfer_to_human(reason="Account suspended")] - sub_goals [transferred_to_human] - (an agent that transfers every caller on arrival passes this. Whether it - looked the account up, and found the suspension, is never measured) - -GOOD solution [find_rider(phone=...), get_account(rider_id=...), - transfer_to_human(reason="Account suspended")] - sub_goals [rider_identified, account_state_checked, transferred_to_human] - (the transfer now has to be reached by discovering the reason for it) -``` - -## Plan the whole suite, then write incrementally - -Writing scenarios one at a time produces a suite that clumps: five variations on the easy path and -nothing on the parts that break. So partition the work first, out loud, before the first -`submit_scenario`. - -Say how many scenarios each use case gets, **in proportion to how much can genuinely go wrong in -it**. A use case with rules to enforce, information to gather, or state to change earns a large -share; one where little can fail earns one scenario or none. Then, for each use case, name the -distinct **angles** you will write: the ordinary path, the branch that cannot be completed, the -rule under pressure, the state that has to carry, the same request against a differently seeded -world. - -Keep that plan concise and continue immediately unless the person explicitly asked to review it. - -**Pass your plan to it.** The tool takes the split as an argument, and you have just read the -world and know which use cases have -something in them; it is the part of this only you can do. Each slice names its use case, -the angle it should take, how many scenarios it is worth, and why. Left to itself the work is -divided evenly, which is how a use case with one real branch pads to three and one with six gets -three. - -A large request comes back a batch at a time rather than all at once, with the rest offered. When -that happens, show what came back and ask whether to carry on, change direction first, or stop. -Do not silently loop until the number is reached. - -Use `submit_scenario` for what it is good at: one scenario somebody asked for by name, a -replacement for one that came back wrong, or filling a specific gap in a suite that already -exists. Anything described as a number of scenarios is a suite. -After inspecting the world, submit the first scenario in the same response. Then prove and save -one scenario at a time. Never silently compose the whole suite before the next tool call: the UI -must show progress, and already-proved work must survive a stopped or timed-out model turn. - -## Fixture quality is part of correctness - -Use source seed data where it exists, but do not make every scenario the same seeded caller with -different prose. Add scenario-local records with `setup_code` when coverage needs a person, -credential, address, balance, status, code, or prior transaction the base world does not contain. -`ready_code` must verify those exact records. - -There is one important exception: when the contract says the target's store is hardcoded and -process-local, with no configuration or injection seam, `setup_code` cannot add or alter target -records. The world and the live target are separate process-local copies. In that case use only -exact source-seeded records already present in the frozen base, keep setup empty for those records, -and settle outcomes from captured calls/results. Never invent an ID or add a scenario-local row; -if coverage requires state absent from the submitted seed, report that the target needs a seed or -reset seam instead of writing an unexecutable scenario. - -Every scenario must include a `fixture` manifest whose origin field is set to seed, generated, or -mixed, plus the exact identity, credentials/verification data, locations, preferences and -account state the caller may rely on. This manifest is supplied to the live caller model; facts -hidden only in setup code cannot be answered reliably in a phone call. - -- Use different realistic names, phone numbers, locations, account histories and payment states. -- Generate a different non-trivial OTP for each scenario that uses one. Never use `123456`, - repeated digits, ascending/descending sequences, or a code copied from another scenario. -- Avoid demo clichés such as Alex/Jordan Test, `555` phone numbers, `123 Main Street`, card - `4242`, and identical addresses unless they are genuinely present in submitted seed data and - the test specifically depends on that record. -- Keep every fact internally consistent: the caller's persona, phone, account row, OTP row, - payment method, market, currency, saved places and instruction must describe the same person. -- Vary outcome as well as wording: success, refusal, correction, ambiguity, retry, stale state, - unavailable dependency and recovery should not all share one happy-path fixture. - -## Write from more than one point of view - -A suite written from a single vantage point tests a single vantage point, however many scenarios -it has. Left alone, anyone writing tests drifts toward the ones they thought of first, which are -usually the ones the agent was built for. - -So work the plan from several stances in turn, and say which one each scenario came from. These -are the ones that reliably find different things: - -- **The engineer who built it**, testing what they know is fragile in their own code: the branch - with the most conditions, the operation that cannot be repeated, the value that is validated in - one place and not another. -- **The adversary**, hunting requests that sit exactly on a rule's edge: the thing just barely not - permitted, the request that is fine on its own and forbidden in this state, the pressure to skip - a step the rules require. -- **The newcomer**, who does not know the agent's vocabulary and asks in their own words: names - the thing wrongly, gives a value in a form nobody expected, does not know which of two things - they have. -- **The operator**, recreating what production traffic actually produces: a record already in an - awkward state, a request about something that has already been dealt with, the same thing asked - twice. -- **The product owner**, testing the promises made about this agent one at a time: for each thing - it claims to do, a scenario where doing it correctly is the whole question. - -Every stance still obeys the bar above: a real person could bring it, a competent agent could -fail it, and the values are real. A stance chooses *what to look at*, never whether the scenario -has to be honest. - -Two rules keep this from turning into noise. **Each scenario carries one use case and one branch, and no two scenarios carry the same pair**: a duplicate is either the same test twice or one of them is mislabelled, and it hides a gap while appearing to fill it. Several scenarios sharing a use case is normal and expected; that is what branches are for. What is not allowed is two rows that agree on both. And a stance that produces nothing new -for a given agent produces nothing: an agent with no rules to bend does not need an adversarial -scenario invented for it. - -## Organise by use case, then by branch - -A login flow is not one row with the happy path and the edge cases inside it. It is several: -login with a password, login with a provider, forgotten password, account locked. Do the same -here. Find the agent's real use cases and let their branches be the scenarios. - -**Different outcomes are different scenarios.** The customer who accepts a substitute and the -customer who refuses one are two rows, not one. - -## The three gates - -Every scenario is put through these before it is kept. You are told which one failed. - -**1. Ready.** The world is restored, your `setup_code` runs, then your `ready_code`. The world -must end up holding what your scenario presumes. - -This is the one people skip and it is the one that saves you. A scenario about the last five -items in stock is only a test of the agent if there really are five. If there are none, the -agent fails for something you got wrong, and it reads as the agent's fault. `ready_code` is how -you make that impossible. - -**2. Solvable.** Your reference solution is played through that world and the checks of every -sub-goal you named must pass. If they do not, either the scenario cannot be passed at all or a -check is wrong. - -**3. Not vacuous.** The same checks run again with nothing done, and must fail. A check that -passes while the agent does nothing grades nothing while reporting a result. - -Gate 3 has a common trap. If your scenario is about something that must *not* happen, checking -the world alone cannot show it: an untouched world looks exactly like one where the agent -correctly refused. Check the calls instead — that the agent tried, and that the attempt was -refused rather than succeeding. - -## Writing setup_code - -Python defining `setup(world)`. Leave it empty when the base world is already right. - -**Write every setup against the base world, never against a scenario you wrote before it.** At run -time each scenario restores its own copy of the frozen base and applies only its own setup, so -nothing another scenario did is there. This is easy to get wrong while writing several in a row: -you have just set an order to "delivered" for one scenario, and the next one reads as though that -still holds. It does not. If a scenario needs a record in a particular state, its own setup puts -it there, whatever any earlier scenario happened to do. The same goes for the calls you make while -rehearsing with `try_calls`: those run on a throwaway copy and change nothing anybody else sees. - -You have two ways to change things, and **neither of them names what the world is kept in**. A -scenario that wrote SQL would only work against a world that happened to be a database, and the -store is the thing that varies most between agents. - -**Prefer the agent's own tools.** It goes through the same path the agent will, so anything the -world would refuse to you would have refused the agent too. - -```python -def setup(world): - world.call("add_to_stock", {"item_id": "widget", "quantity": 5}) -``` - -**Otherwise change the world directly**, in collections and records: - -```python -world.put(collection, record) # add one table record; the table already owns its primary key -world.change(collection, key, changes, by=...) # change one record -world.drop(collection, key, by=...) # remove one, or all of them with no key -``` - -Only use `world.put(..., key=...)` for an in-memory mapping that is not a table. A table's primary -key is already present in the record and must not be repeated as `key=`. `world.state()` shows you -every collection and what is in it, which is how you find out which you are dealing with. - -```python -def setup(world): - world.change("stock", "widget", {"quantity": 5}, by="item_id") -``` - -Use the direct route only for states no tool can produce: a record already in a condition the -agent could never create itself. - -## A collection is not always a list - -`world.state()` gives every collection this world has, and their shapes differ by agent. A table -gives a list of records. A collection the agent's own code keeps is often a mapping keyed by -identifier, and iterating that yields the keys, which are strings, so reading a field off one fails. - -```python -held = world.state()["some_collection"] -records = list(held.values()) if isinstance(held, dict) else held -``` - -Look before you write. `inspect_world` shows you which is which, and this applies to `setup_code`, -`ready_code` and every check. - -## Writing ready_code - -Python defining `ready(world)`. Return `None` when the world holds what the scenario presumes, -or a sentence naming what is missing. - -Check the thing your scenario actually depends on, not everything. - -```python -def ready(world): - rows = world.state()["stock"] - widget = next((r for r in rows if r["item_id"] == "widget"), None) - if widget is None: - return "no widget in stock at all; this scenario is about its last five" - if widget["quantity"] != 5: - return f"stock says {widget['quantity']} widgets, this scenario needs exactly 5" - return None -``` - -## The solution is not optional - -Every scenario carries what a correct agent would do. It is never run against the agent under -test. It exists to prove the scenario can be passed at all, and it is what gate 2 uses. - -Work it out with `try_calls` before you submit. Run the calls, pass your `setup_code` so you see -the world the agent would actually face, look at the state they leave, and confirm the sub-goals -you are naming respond to it. - -**A one-call solution is almost always wrong.** The agent does not begin the call knowing who it -is talking to or what is true of their account, so before the call that resolves the scenario it -has to find that out: identify the caller, read the record, check the state that decides the -answer. Those lookups belong in the solution, and the sub-goals have to name them. Write the -single terminal call on its own and the scenario passes for an agent that fires it blind, having -established nothing, which is the one behaviour a refusal scenario exists to rule out. - -Refusals and transfers are where this goes wrong most often, because the terminal call is so -obviously the point of the scenario. It is not: *deciding* to refuse is the point, and a decision -that was never reached from evidence was never tested. - -## Reuse the sub-goals - -Name entries from the shared catalogue. Do not restate them in your own words, and do not invent -a new one where an existing one means the same thing. That sharing is what lets results add up: -the same sub-goal failing in seven of twelve scenarios is one sentence somebody can act on. - -If something genuinely needs checking and no entry covers it, add one with `add_sub_goal`, with -its check in code. Prefer code over a judged check — you have the world afterwards and every -call with its arguments, and most things worth checking are visible in one of them. - -## What makes a suite worth running - -Spread across these. Ten happy paths tell you nothing you did not already know. - -- **The ordinary branch**, done cleanly. You need a baseline. -- **The branch that cannot be completed**: the item is not there, the record does not exist, the - option is outside what the tool accepts. The right behaviour is to refuse clearly and offer - what is possible. -- **The rule under pressure**: the person pushes for something a hard rule forbids, twice. - Giving way under pressure is the failure most worth catching. -- **State that has to carry**: do something, change your mind, undo it, confirm. The agent has to - know what it did two turns ago. -- **The same use case with the world seeded differently.** In stock and out of stock are two - rows, not one. - -## If the contract is wrong - -You will sometimes find that the agent's contract does not match what the world does — a tool -that accepts a value it was not recorded as accepting, a rule that is not really a rule. Correct -it with `amend_contract`, `add_rule`, `drop_rule` or `fix_tool` and say why. Every amendment is -recorded on the contract. - -Never work around a contract you believe is wrong. A scenario written to dodge a bad contract -hides the problem and everything built afterwards inherits it. - -## How to work - -1. `inspect_world` with no table, then look at the ones that matter. Read the sub-goals already - defined. -2. Read the agent's hard rules. Each one is a branch waiting to be written. -3. For a suite, say how you are splitting it across the agent's use cases, then write and - submit them one at a time. A large ask comes back a batch at a time rather than all at once. - writes the whole thing and saves it, and you report what came back. -4. For a single scenario: work out the solution, `try_calls` it with your `setup_code`, then - `submit_scenario`. -5. Read what comes back. A refusal names which gate failed and why. -6. `save_scenarios` when you have the number that was asked for. - -## Finishing - -Say what the suite covers and what it does not, which sub-goals carry the most scenarios, and -name anything you could not test because the environment or the contract does not support it. diff --git a/src/fi/alk/harness/tools.py b/src/fi/alk/harness/tools.py index bfe2b6da..49ad6784 100644 --- a/src/fi/alk/harness/tools.py +++ b/src/fi/alk/harness/tools.py @@ -211,6 +211,16 @@ def contract_tools(destination: Path) -> Any: "description": "True if a person talks with it turn by turn.
