Jinja2 Template Support in the Playground

[mmabrouk]

Problem Statement

The playground currently treats prompts as plain text with simple variable substitution. Users cannot use conditional logic that is common in production prompt engineering workflows.

Proposed Solution

We are adding Jinja2 template support to the playground. This will allow users to:

• Use conditional statements (e.g., check if a variable is empty or contains specific text)
• Apply filters and transformations (e.g., uppercase, lowercase, truncate)
• Use template blocks for better prompt organization

Prompt Type Configuration
The type of prompt (plain text or Jinja2) will become part of the prompt schema. When you save a prompt with Jinja2 templates, the schema will store this information.

SDK Support
The SDK will provide helper functions to format prompts according to their type. For Jinja2 prompts, the SDK will handle template rendering before sending to the LLM.
