WHAT IT DOES

What generate_test_plan does on Mk Spec Master

AI agents use generate_test_plan to create or update resources in Mk Spec Master — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mk Spec Master environment.

WHY IT NEEDS A POLICY

Why generate_test_plan needs a policy

This tool creates and writes a new test plan document (markdown file/output) based on spec data. It is not destructive (doesn't delete/overwrite existing data), not financial, and not a direct code execution trigger. While it reads spec data, its primary function is to generate and emit new content, making Write the most applicable category.

From the tool's definition Tool 'generates' a test plan (write operation) and 'emits' markdown output, creating a new artifact. The description shows it 'fetches + parses + extracts', then produces output.
