Curated tool names (v2 server). Call tools by the exact names below (createForm, getForm, updateForm, …) — they match the curated tool set in /simulator. Older docs may show post-forms-… style names; ignore those.

Form-level extras: createFormAccount / getFormAccounts / removeFormAccount (default accounts auto-applied to a form's actors) and getFormsTree / getLinkedForms (navigate the form tree / UAT).

Simulator.Company Form Designer

You design form templates for Simulator.Company using the simulator MCP server. Forms are the schema layer of the platform — they define the structure, fields, and field types of every actor.

Alias — read this. In the product UI a form is called an Account Template (Ukrainian «Шаблон рахунків»). "Form", "form template", and "Account Template" are the same entity. Each actor created from a form is an instance of that template (often called a record / рахунок). When the user says "Account Template" or "Шаблон рахунків", they mean a form — use these tools.

To create/update/search the instances (actors) of a template, use the simulator-actors skill, which documents the actor data value protocol.

Workspace Context Check (MANDATORY FIRST STEP)

Before doing anything else, verify the WorkspaceID (accId) is known:

1. Check whether the user already specified accId (current message, history, or session).

2. If accId is not provided, ask:

   Ask the user — in their own language (English, Ukrainian, or Russian) — which workspace to work in, i.e. for the Workspace ID (accId).

   Do not call any MCP tools until the user provides accId.

3. Once known, use it in all subsequent calls.

Reading a form's "knowledge"

A form carries human-written documentation that is the authoritative source for what it and its fields mean. Read and interpret it before answering about a form's purpose or the meaning of a field/parameter — never guess from a field's title/class:

• Form-level description — a top-level key on the form object; explains the form's purpose.
• Field-level description — a flat, optional key on each field at sections[].content[].description (the field's helper text). Present on some fields, absent on others.

Because reads should always pass a filter, include description and sections in the getForm filter when you need to understand a form or its fields — a narrower filter drops them. If the relevant description isn't already in context — e.g. a follow-up question a few turns later — re-read the form with getForm; do not answer from memory or invent a field's meaning.

Form Concepts

Forms are templates. Actors are instances.

Form / Account Template          →  Actor (instance / record)
──────────────────────────────────────────────────────────────
title: "Car"                        title: "Toyota Camry 2023"
sections: [ {content:[fields]} ]    data: { item_<id>: <value>, … }

A form is, concretely, a sections[] array. Each section = {title, content[]}. Each content item is a field with a stable id of the form item_<digits> — and that id is the key the actor uses in its data object. Get this right: actor data is keyed by field id, never by the field title or its secondary key.

Form Types

Type	isTemplate	Description
Regular form	true	User-created reusable templates for domain actors
Private/draft	false	Non-template form. Not returned by getForms/searchForms — keep its id from the createForm response and read it with getForm
System form	built-in	Platform-provided: Graph, Layer, Event, Script, Account, Currency, Transaction, Transfer, Reaction, Stream

Top-level form shape

{
  "title": "FullForm",
  "ref": "formRef_…",          // optional external ref, unique per workspace
  "color": "#c6dcba",          // hex color of actors of this form
  "description": "",
  "sections": [ /* see below */ ],
  "settings": {},               // form-level settings
  "valencyRules": {}            // link/valency constraints between actors (optional)
}

Field item properties

Property	Meaning
id	item_<digits> — the key actors use in data. Unique within the form.
key	secondary numeric key (internal indexing) — not used to key actor data; may be absent
class	widget type (catalogue below)
type	sub-type for edit: text(default)/password/email/phone/int/float
title	display label
value	default value (shape depends on class)
options	[{title,value,color?}] for radio/select/multiSelect
extra	class-specific config (optionsSource, calendar config, …)
required, regexp, errorMsg, description, align, color, visibility	as named; visibility ∈ visible/disabled/hidden

Field class catalogue

class	Purpose	Form-side specifics
edit	text / number input	type: text/password/email/phone/int/float; regexp, errorMsg
check	checkbox	default value "true"/"false"
radio	single choice	options[], optional align
select	single-select dropdown	static options[] or dynamic extra.optionsSource (below)
multiSelect	multi-select dropdown	static options[]
calendar	date / datetime	extra.{time,minDate,maxDate,dateRange,timeZone,static} (unix seconds)
upload	file upload	value defaults to {}
label	static text	value is the text; no actor data
button	action button	title is the caption; no actor data
image	image	value is the URL; no actor data

Dynamic select — extra.optionsSource.type

type	value payload	options from	data type
manual (default)	—	the field's own static options[]	— (no type)
layer	{id:<layer UUID>}	actors on that layer	actor
actorFilter	{id:<filter UUID>}	a saved actor filter	actor
actorsBag	—	the current actors-bag set	actor
actors	{ids:[<actor UUID>,…]}	an explicit actor list	actor
formFilter	{id:<form id>}	the actors of that form	actor (value=actor UUID)
forms	—	workspace forms themselves	form (value=form id)
currencies	—	workspace currencies	currency
accountNames	—	workspace account-name definitions	accountName
workspaceMembers	—	workspace members (users)	workspaceMembers
api / corezoidSyncApi	endpoint cfg / {convId,apiLogin,apiSecret}	a generic / Corezoid HTTP source	(source-defined)

Link direction — for actor-reference fields (layer/actorFilter/actorsBag/actors/formFilter) picking an actor auto-creates a hierarchy link. Default is current-actor→referenced-actor; set extra.reverseEdge:true on the field to reverse it (referenced-actor→current-actor). Omit/false keeps the default.

MCP Operations for Forms

Goal	Tool
List forms in a workspace	getForms(accId="ws_xxx")
List system forms	getForms(accId="ws_xxx", formTypes="system")
Get a form by id	getForm(formId=42)
Search forms (do this before creating)	searchForms(accId="ws_xxx", q="car")
Create a form	createForm(accId, isTemplate=true, title, sections=[…])
Update a form	updateForm(formId=42, title, sections=[…])
Set form status	setFormStatus(formId=42, status="active")
Delete a form	deleteForm(formId=42)

Save tokens with filter. getForm, getForms, searchForms accept an optional filter field-selection arg (comma-separated, e.g. filter="id,title,description,sections"); the server returns only those fields. Templates can be large — request just what you need, but keep description (form purpose) and sections (field definitions, incl. each field's description) when you need to understand the form.

Create a form

createForm(
  accId="ws_xxx",
  isTemplate=true,
  title="Car",
  color="#c6dcba",
  description="Vehicle tracking template",
  ref="car-form",
  sections=[
    { "title": "Basics", "content": [
      { "id": "item_make",  "class": "edit", "title": "Make",  "required": true, "visibility": "visible" },
      { "id": "item_model", "class": "edit", "title": "Model", "required": true, "visibility": "visible" },
      { "id": "item_year",  "type": "int", "class": "edit", "title": "Year", "regexp": "[0-9]", "visibility": "visible" },
      { "id": "item_active","class": "check", "title": "In service", "value": "false", "visibility": "visible" }
    ]},
    { "title": "Classification", "content": [
      { "id": "item_cond", "class": "select", "title": "Condition", "value": [],
        "options": [ {"title":"excellent","value":"c1"}, {"title":"good","value":"c2"}, {"title":"fair","value":"c3"} ],
        "visibility": "visible" },
      { "id": "item_owner", "class": "select", "title": "Owner", "value": [], "options": [],
        "extra": { "optionsSource": { "type": "workspaceMembers" } }, "visibility": "visible" }
    ]}
  ])

Returns {"id": 42, "title": "Car", "ref": "car-form", …}.

Generate a unique id per field (item_<something unique>). Keep ids stable across updateForm calls — they are the contract with existing actors' data.

Update a form

updateForm replaces title + sections. To add a field, fetch the current sections with getForm, append the new field item (with a fresh id), and send the full array back. Renaming a field's title is safe; changing its id orphans the data in already-created actors.

Updating a form does not retroactively change actors already created from it.

Form trees & multiform actors (UAT)

Forms can be linked into a tree via parentId (parents ↕ children). The platform calls such a tree a UAT. An actor can then instantiate several forms at once — a multiform actor (e.g. a base "Person" form + a "Position" form).

• createForm(..., parentId=<id>) links a form under a parent in the tree.
• Navigate the tree with getFormsTree(accId, formId) (the whole UAT a form belongs to — it resolves to the root and lists all descendants) and getLinkedForms(typeLink, formId) (typeLink="children" or "parents" — the directly-linked forms). Use these to learn which forms' fields a multiform actor will carry before writing its data.
• The actor-side form-set endpoint (PUT /actors/actor_forms/{actorId}) is still internal / not a curated tool — but multiform actor data is already fully writable (below).

What you can do today is read/write multiform actor data. Fields are namespaced by their owning form via __form__<formId>:<itemId>:

• the actor's root form fields → plain item_<id>;
• fields of another form in the set → __form__<thatFormId>:<itemId>.

{ "name": "Kulo Oleksandr", "__form__16951:position": "Software engineer" }

The prefix changes only the key; the value still follows the per-class shapes. See the simulator-actors skill for writing this data.

Accounts on a form vs on an actor

There are two ways to give actors accounts — pick by intent:

1. Default accounts ON THE FORM (model definition) — createFormAccount

Define the account once on the form template and the backend auto-creates it on every actor of that form (existing and future); removing it deletes it from all of them. This is the clean way to shape the account model of a whole form.

createFormAccount(formId=42, nameId="<account-name id>", currencyId=1,
                  accountType="fact",          # fact | plan | min | max | avg (default fact)
                  treeCalculation=false, search=true)
getFormAccounts(formId=42)                      # list the form's default accounts
removeFormAccount(id=<form-account id>)         # auto-removes from all actors — confirm first

• accountType is the value type (fact default | plan | min/max/avg) — the same enum createAccount uses. There is no asset/liability/income type; the account name carries the meaning.
• Prerequisites are the same: the nameId (getAccountNames/createAccountName) and currencyId (getCurrencies/createCurrency) must already exist.

2. Ad-hoc account on ONE actor — createAccount

For a one-off account on a single actor (not every actor of the form), attach it directly (accountType defaults to fact; set counterType="counter" for a metric counter):

createAccount(actorId="…", nameId="…", currencyId=1)

Goal	Tool
List / create account-name definitions	getAccountNames / createAccountName(accId, name=…)
List / create currencies	getCurrencies / createCurrency(accId, name, symbol, precision)
Default account for ALL actors of a form	createFormAccount(formId, nameId, currencyId, accountType)
Account on ONE actor	createAccount(actorId, nameId, currencyId, accountType)

Detailed financial workflows (transactions, transfers, counters, balances, reports) belong to the simulator-finance skill — defer there for anything beyond defining/attaching an account.

Post-creation analysis & account suggestions (optional, ask first)

After creating a form, you may offer the user a set of accounts worth tracking on each actor of this type. This is advisory — present a plan and only act on confirmation.

Step 1 — analyze the form. One-line purpose + a fields-overview table + notes on which fields/domain imply accounts.

Step 2 — fetch existing names & currencies in parallel: getAccountNames(accId) and getCurrencies(accId); match by title (case-insensitive) and reuse their ids.

Step 3 — derive 3–6 account suggestions. From explicit fields and domain context:

Each suggestion is an account name · currency, marked (counter) where it's a tally rather than a money balance. The name carries the meaning — there is no asset/liability/expense type.

Domain entity	Suggested accounts (name · currency)
Vehicle / Equipment	Mileage (Km, counter), Fuel Cost (USD), Maintenance (USD), Downtime (Hours, counter)
Employee / Staff	Hours Worked (Hours, counter), Vacation Days (Days, counter), Salary Paid (USD)
Project / Task	Hours Spent (Hours, counter), Budget (USD), Actual Cost (USD)
Product / SKU	Stock (pcs, counter), Sales (pcs, counter), Revenue (USD)
Client / Customer	Orders (pcs, counter), Total Spent (USD), Debt (USD)

If the entity matches no row, reason from first principles: what accumulates over time, what a manager wants on a dashboard, what compares across actors of this type.

Step 4 — present the plan (account name · currency · counter? · exists/new) and wait for "yes".

Step 5 — execute per pair: ensure the currency (getCurrencies→reuse, else createCurrency) and account name (getAccountNames→reuse, else createAccountName) exist, then createAccount(actorId, nameId, currencyId, search=true) (add counterType="counter" for the counter rows) on each target actor — or define them once on the form with createFormAccount so every actor gets them. Report a results table.

Smart Forms (CDU / Scripts)

The Script system form type creates "Smart Forms" — dynamic templates with custom logic. Find the Script system form:

getForms(accId="ws_xxx", formTypes="system")   # find title containing "Script" / "CDU"

Then create a Smart Form actor from it like any other actor. The full Smart-Form / CDU runtime contract is documented in $CLAUDE_PLUGIN_ROOT/docs/user-flows/smart-forms.md and …/cdu-page-protocol.md.

Note: the Applications / Smart-Forms MCP tools are not registered at this stage (docs-only). Treat Smart Forms here as a documentation/reference topic.

Tips

• isTemplate=true makes a reusable template visible to all users; false is a private/draft form that getForms/searchForms do not list. Creating a draft form and then searching for it by title finds nothing, so a "create if missing" flow must use isTemplate=true or remember the id.
• Form ref must be unique per workspace.
• System forms cannot be modified — use them as-is by their ids.
• Field ids are the contract with actor data — generate unique ones and never change them on edit.
• label / button / image fields are display-only and produce no actor data.
• To create the instances of a template, hand off to simulator-actors.
