What it does

Patterns Crud is an agent skill from mendixlabs/mxcli. Standard Create/Read/Update/Delete microflow patterns with the naming conventions that go with them. Use when writing the action microflows behind page buttons rather than looking up individual syntax.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Mendix cli tool, a headless way to work with Mendix projects. Enables Mendix projects for use with 3rd party agentic coding tools like Claude Code and Copilot. Includes a… The licence is Apache-2.0.

When your agent uses it

Writing the action microflows behind page buttons rather than looking up individual syntax

Example prompts

“/patterns-crud”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

Always validate before commit: Call VAL_ microflow in ACT_Save
Events are on by default: a bare commit $entity triggers the event handlers; write commit $entity without events only to skip them
Close page on success: Use close page after successful save/delete
Rollback on cancel: Use rollback $entity to discard changes
Initialize defaults: Set default values in ACT_New microflow
Return Boolean: All action microflows should return success status

What it can do on your machine

Read from SKILL.md and the folder at commit a924d11. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are mdl).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Patterns Crud loads about 1.3k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 212 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~54
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Standard Create/Read/Update/Delete microflow patterns with the naming conventions that go with them. Use when writing the action microflows behind page buttons rather than looking up individual syntax.

CRUD Action Patterns

Standard patterns for Create, Read, Update, Delete operations on entities.

Naming Conventions

Prefix	Purpose	Example
`ACT_`	Action microflow (page button)	`ACT_Customer_Save`
`VAL_`	Validation microflow	`VAL_Customer_Save`
`DS_`	Data source microflow	`DS_Customer_GetAll`
`SUB_`	Sub-microflow (internal)	`SUB_Customer_SendEmail`

Save Pattern (Create/Update)

Used for Save buttons on NewEdit pages.

mdl

mdl 1;
/**
 * Save action for Customer NewEdit page
 * Validates, commits, and closes the page
 *
 * @param $Customer The customer to save
 * @returns true if saved successfully
 */
create microflow Module.ACT_Customer_Save (
  $Customer: Module.Customer
)
returns boolean
begin
  -- Validate first
  $IsValid = call microflow Module.VAL_Customer_Save(Customer = $Customer);

  if $IsValid then
    commit $Customer;
    close page;
  end if;

  return $IsValid;
end;

Validation Pattern

Companion validation microflow for Save actions.

mdl

mdl 1;
/**
 * Validate Customer before save
 *
 * @param $Customer The customer to validate
 * @returns true if valid
 */
create microflow Module.VAL_Customer_Save (
  $Customer: Module.Customer
)
returns boolean
begin
  declare $IsValid boolean = true;

  -- Required field validation
  if $Customer/Name = empty then
    validation feedback $Customer/Name message 'Name is required';
    set $IsValid = false;
  end if;

  if $Customer/Email = empty then
    validation feedback $Customer/Email message 'Email is required';
    set $IsValid = false;
  end if;

  -- Business rule validation
  if $Customer/CreditLimit < 0 then
    validation feedback $Customer/CreditLimit message 'Credit limit cannot be negative';
    set $IsValid = false;
  end if;

  return $IsValid;
end;

Delete Pattern

Used for Delete buttons with confirmation.

mdl

mdl 1;
/**
 * Delete a customer
 * Called after user confirms deletion
 *
 * @param $Customer The customer to delete
 * @returns true if deleted
 */
create microflow Module.ACT_Customer_Delete (
  $Customer: Module.Customer
)
returns boolean
begin
  delete $Customer;
  close page;
  return true;
end;

Cancel Pattern

Used for Cancel buttons (discard changes).

mdl

mdl 1;
/**
 * Cancel editing and close page
 * Discards uncommitted changes
 *
 * @param $Customer The customer being edited
 * @returns true
 */
create microflow Module.ACT_Customer_Cancel (
  $Customer: Module.Customer
)
returns boolean
begin
  rollback $Customer;
  close page;
  return true;
end;

Create New Pattern

Used for New/Add buttons on overview pages.

mdl

mdl 1;
/**
 * Create new customer and open edit page
 *
 * @returns true
 */
create microflow Module.ACT_Customer_New ()
returns boolean
begin
  $NewCustomer = create Module.Customer (
    IsActive = true,
    CreatedDate = [%CurrentDateTime%]
  );

  show page Module.Customer_NewEdit (Customer = $NewCustomer);
  return true;
end;

Data Source Pattern

Used for data grid/list view sources.

mdl

mdl 1;
/**
 * Get all active customers
 * Used as data source for Customer overview
 *
 * @returns List of active customers
 */
create microflow Module.DS_Customer_GetActive ()
returns list of Module.Customer
begin
  -- retrieve creates the list variable directly — never declare a list first
  retrieve $Customers from Module.Customer
    where IsActive = true;

  return $Customers;
end;

Edit Pattern

Open existing entity for editing.

mdl

mdl 1;
/**
 * Open customer for editing
 *
 * @param $Customer The customer to edit
 * @returns true
 */
create microflow Module.ACT_Customer_Edit (
  $Customer: Module.Customer
)
returns boolean
begin
  show page Module.Customer_NewEdit (Customer = $Customer);
  return true;
end;

Complete CRUD Set

For a typical entity, create these microflows:

Microflow	Purpose	Parameters
`ACT_Entity_New`	Create new	None
`ACT_Entity_Edit`	Open for edit	`$entity`
`ACT_Entity_Save`	Save changes	`$entity`
`VAL_Entity_Save`	Validate	`$entity`
`ACT_Entity_Delete`	Delete	`$entity`
`ACT_Entity_Cancel`	Cancel edit	`$entity`
`DS_Entity_GetAll`	List all	None

Best Practices

Always validate before commit: Call VAL_ microflow in ACT_Save
Events are on by default: a bare commit $entity triggers the event handlers; write commit $entity without events only to skip them
Close page on success: Use close page after successful save/delete
Rollback on cancel: Use rollback $entity to discard changes
Initialize defaults: Set default values in ACT_New microflow
Return Boolean: All action microflows should return success status
