Matches

Contains Pattern

Check whether text contains a pattern or substring.

Purpose

• Enable conditional logic based on content
• Pattern matching for flow control
• Content validation
• Simple filtering

Input Format

Accepts a Note containing text to check.

Parameters

Required:

• pattern - Text string or regex pattern to match

Optional:

• match_type - "substring" (default), "regex", or "exact"

Output Format

Returns a Note containing:

• "true" if pattern found
• "false" if pattern not found

Usage Examples

Simple substring check:

{"type":"matches","target":"$text","pattern":"error","out":"$has_error"}

Regex pattern match:

{"type":"matches","target":"$email","pattern":"^[a-z]+@example\\.com$","match_type":"regex","out":"$is_valid_email"}

Exact match:

{"type":"matches","target":"$status","pattern":"complete","match_type":"exact","out":"$is_complete"}

Match Types

• substring: Pattern appears anywhere in text (case-sensitive)
• regex: Full regex pattern matching
• exact: Entire text must exactly match pattern

Guidelines

• Case-sensitive by default
• Returns boolean as text ("true"/"false")
• Use for conditional logic in plans
• Combine with other conditionals as needed

Examples

Substring (default):

Text: "Error occurred in module X"
Pattern: "Error"
Result: true

Regex:

Text: "user@example.com"
Pattern: ".*@example\\.com$"
Result: true

Exact:

Text: "done"
Pattern: "done"
Result: true

Text: "almost done"
Pattern: "done"
Result: false
