What Setup Custom Libraries does

Setup Custom Libraries registers or updates existing Simulink block libraries so agent-assisted model building can prefer them over built-in blocks. Use it to add `.slx` libraries, configure block policy, and populate the knowledge index for declared libraries.

Setup Custom Libraries is cataloged under AI Engineering on DirSkills. Setup Custom Libraries comes from a repository tagged agent-skills, claude-code, codex-plugin, engineering-agents and github-copilot.

Excerpt

Setup Custom Libraries

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 (gatePass: false)
Never invoke when found: false — that means no custom libraries are configured and the user hasn't asked for them

When NOT to Use
