if

Runs one block of commands or another, based on a condition.

Fields

Field	Type	Description
`condition`required	Python expression	Boolean expression, evaluated once: true runs 'then', false runs 'else'.
`then`	command block	Commands to execute when the condition evaluates to true (the 'then' branch).
`else`	command block	Commands to execute when the condition evaluates to false (the 'else' branch).

Example

"if": {
  "condition": "{ location['country_code'] != 'US' }",
  "then": {
    "fail": "{ f'This agent supports only locations in the USA. You are in {location['country_name']}.' }"
  },
  "else": {
    "progress": "Location looks good"
  }
}

Rules

The condition is evaluated once, as a boolean.
then and else are ordinary command blocks. Any command may appear in them, including another if.
break and continue inside a branch act on the enclosing loop. return, end and fail leave the function or the agent as usual.
