Running Templates in PromptPlan: Validation, Rendering, and Output

Execution flow

When you run a template, PromptPlan:

1. Validates required fields
2. Replaces placeholders with provided values
3. Builds final prompt text
4. Executes the run
5. Stores output and metadata in run history

Validation behavior

Before execution, PromptPlan checks:

• required fields are present
• select values are valid options
• inputs follow field constraints

Run output

Each run returns:

• generated output text
• model used (if available)
• timestamp
• input values snapshot

Example

Template body:

Write a concise brief for {{audience}}.
Context:
{{source_text}}

Input values are merged at run time, creating one final prompt instance.
