WHAT IT DOES

What skillsmp_install does on Skillsmp

WHY IT NEEDS A POLICY

Why skillsmp_install needs a policy

Installing a skill writes new data or configurations to a namespace (global, project, or sandbox). This is a reversible write operation (skills can be uninstalled/removed), not inherently destructive, financial, or code execution. Medium severity because installing to a global namespace could affect all users or projects on the system.

From the tool's definition 'Install a skill to specified namespace' — installs/creates a skill in a target namespace
