Setup Custom Libraries

Register or update custom Simulink block libraries so the agent prefers them over built-in blocks during model building.

When to Use

• User asks to set up, register, add, or configure custom libraries
• User wants to add new .slx files to an existing library configuration
• User says "setup custom libraries", "add my library", "configure libraries", "add a new library file"
• building-simulink-models routes here via the policy gate

When NOT to Use

• Only configuring block exclusions or parameter protection (libraries already declared) → configuring-block-policy
• Only curating block descriptions/categories (libraries already declared) → curating-library-kg

Workflow

Do this FIRST and ALONE — no other tool calls in the same message.
