def extract_hash_value(code, key)
  match = code.match(/#{key}:\s*\{([^}]*)\}/)
  return {} unless match

  hash_content = match[1].strip
  return {} if hash_content.empty?

  # Parse simple key: 'value' or key: "value" pairs
  result = {}
  hash_content.scan(/(\w+):\s*(['"])([^'"]*)\2/) do |k, _quote, v|
    result[k.to_sym] = v
  end
  result
end

#extract_string_value(code, key) ⇒ String

Extract a string value from DSL code (e.g., instructions: "...")

Parameters:

  • Code snippet

  • Key to extract

Returns:

  • Extracted value or empty string

def extract_string_value(code, key)
  # Match both single and double quoted strings, including multi-line
  match = code.match(/#{key}:\s*(['"])(.*?)\1/m) ||
          code.match(/#{key}:\s*(['"])(.+?)\1/m)
  match ? match[2] : ''
end

#load_agent_definition(ctx, agent_name) ⇒ Object?

Load agent definition from ConfigMap

Parameters:

  • Cluster context

  • Name of the agent

Returns:

  • Agent definition or nil if not found

    # For now, we'll create a mock definition with the task structure
    # In a full implementation, this would eval the code safely

    nil
  end
end

#parse_agent_code(code) ⇒ Object

Parameters:

  • Ruby agent code

Returns:

  • Agent definition structure
