Class: PromptObjects::Universal::ModifyPrompt

Inherits:
Primitive show all
Defined in:
lib/prompt_objects/universal/modify_prompt.rb

Overview

Universal capability for POs to modify their own or other POs' markdown body (prompt). This enables self-modification of behavior, learning, and identity. Note: This does NOT modify the frontmatter (capabilities, etc.) - use add_capability for that.
