Customizable Prompt Templates For Completion And Chat

via “prompt template management with variable substitution and formatting”

The agent engineering platform

Unique: Implements prompt templates as Runnable components with Pydantic-based input validation and partial binding support — templates can be composed, tested, and versioned independently of application code, and variable validation happens at template definition time rather than runtime

vs others: More structured than string formatting because it enforces input schemas and enables composition; more flexible than hard-coded prompts because variables can be bound dynamically at runtime
