WHAT IT DOES

What ollama_create_template does on Promethean OS MCP

WHY IT NEEDS A POLICY

Why ollama_create_template needs a policy

This tool creates or updates templates, which is a Write operation. It modifies data structures reversibly (templates can be updated or replaced), so it does not qualify as Destructive. The severity is medium because malicious template creation could affect downstream processes (e.g., code generation, configuration injection), but the blast radius depends on how these templates are consumed.

From the tool's definition Tool description states: 'Create or update a template (s-expr text stored verbatim)'. The verbs 'create or update' indicate reversible modification of data, and templates are configuration/data artifacts.
