WHAT IT DOES

What create_prompt_basis does on Advanced Prompting Engine

AI agents use create_prompt_basis to create or update resources in Advanced Prompting Engine — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Advanced Prompting Engine environment.

WHY IT NEEDS A POLICY

Why create_prompt_basis needs a policy

This tool creates or generates structured prompt engineering artifacts (a 'basis' framework). This is a reversible write operation—it produces new data structures without executing external code, deleting data, or moving money.

From the tool's definition Tool name 'create_prompt_basis' indicates creation ('create') of a prompt basis artifact. The server description mentions 'generates a principled construction basis' and 'guide the creation of structured' outputs, suggesting the tool constructs and modifies…
