Condition Operators

Comparison Operators

Equal (eq)

{
  "condition": {
    "operator": "eq",
    "left": { "contextPath": "status" },
    "right": "ready"
  }
}

Works with strings, numbers, booleans.

Not Equal (neq)

{
  "condition": {
    "operator": "neq",
    "left": { "contextPath": "error_count" },
    "right": 0
  }
}

Greater Than (gt)

{
  "condition": {
    "operator": "gt",
    "left": { "contextPath": "score" },
    "right": 80
  }
}

Greater Than or Equal (gte)

{
  "condition": {
    "operator": "gte",
    "left": { "contextPath": "items_count" },
    "right": 1
  }
}

Less Than (lt)

{
  "condition": {
    "operator": "lt",
    "left": { "contextPath": "retry_count" },
    "right": 3
  }
}

Less Than or Equal (lte)

{
  "condition": {
    "operator": "lte",
    "left": { "contextPath": "error_rate" },
    "right": 0.05
  }
}

String Operators

Contains (contains)

{
  "condition": {
    "operator": "contains",
    "left": { "contextPath": "message" },
    "right": "error"
  }
}

Also works with arrays:

{
  "condition": {
    "operator": "contains",
    "left": { "contextPath": "tags" },
    "right": "urgent"
  }
}

Existence Operators

Exists (exists)

{
  "condition": {
    "operator": "exists",
    "operand": { "contextPath": "optional_field" }
  }
}

Returns true if variable exists and is not null/undefined.

Is Empty (isEmpty)

{
  "condition": {
    "operator": "isEmpty",
    "operand": { "contextPath": "items" }
  }
}

Returns true for:

  • Empty string ""
  • Empty array []
  • Null/undefined

Logical Operators

AND (and)

All conditions must be true:

{
  "condition": {
    "operator": "and",
    "conditions": [
      {
        "operator": "eq",
        "left": { "contextPath": "status" },
        "right": "complete"
      },
      {
        "operator": "gt",
        "left": { "contextPath": "score" },
        "right": 80
      }
    ]
  }
}

OR (or)

At least one condition must be true:

{
  "condition": {
    "operator": "or",
    "conditions": [
      {
        "operator": "eq",
        "left": { "contextPath": "priority" },
        "right": "high"
      },
      {
        "operator": "eq",
        "left": { "contextPath": "priority" },
        "right": "critical"
      }
    ]
  }
}

NOT (not)

Negates a condition:

{
  "condition": {
    "operator": "not",
    "condition": {
      "operator": "eq",
      "left": { "contextPath": "status" },
      "right": "blocked"
    }
  }
}

Context Path Syntax

Simple Path

{ "contextPath": "variable_name" }

Nested Path

{ "contextPath": "user.profile.name" }

Array Index

{ "contextPath": "items[0]" }

Combined

{ "contextPath": "results[0].score" }

Literal Values

Right-hand values can be literals:

{
  "right": "string value"
}
{
  "right": 42
}
{
  "right": true
}
{
  "right": null
}

When comparing with contextPath on both sides, both values are resolved from context before comparison.

Common Patterns

Check Boolean Flag

{
  "condition": {
    "operator": "eq",
    "left": { "contextPath": "has_tests" },
    "right": "yes"
  }
}

Check Iteration Limit

{
  "condition": {
    "operator": "lt",
    "left": { "contextPath": "current_iteration" },
    "right": 5
  }
}

Check Non-Empty Result

{
  "condition": {
    "operator": "and",
    "conditions": [
      {
        "operator": "exists",
        "operand": { "contextPath": "result" }
      },
      {
        "operator": "not",
        "condition": {
          "operator": "isEmpty",
          "operand": { "contextPath": "result" }
        }
      }
    ]
  }
}
