Register, add, or update existing custom Simulink block libraries and configure block policy and knowledge index.

One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
I am looking at the custom library management menu in my configured project. I selected option (b) to update my block policy. What skill should be loaded?

The instructions your model reads when the skill loads.
Register or update custom Simulink block libraries so the agent prefers them over built-in blocks during model building.
.slx files to an existing library configurationbuilding-simulink-models routes here via the policy gate (gatePass: false)found: false — that means no custom libraries are configured and the user hasn't asked for them.slx library file) → use building-simulink-models skill with model_edit directly. This skill only registers existing libraries; it cannot create library content.configuring-block-policysimulink-curating-library-kgDo this FIRST and ALONE — no other tool calls in the same message.
Call library.settingsLookup() — returns a struct with resolved absolute paths:
found — whether a libraries file was located (satk-libraries.json or legacy reuse-libraries.json)enabled — whether custom libraries are configuredgatePass — whether the gate is satisfieddataRoot — absolute path to the directory containing .satk/kgIndexPath, librariesPath, policyPath — absolute paths to data filesInterpret the result:
found: false → no custom libraries configured. Do NOT proceed with setup unless the user explicitly asked. Return control to the calling skill.gatePass: true, found: true → all data files present and KB populated. Offer management menu (below).gatePass: false, found: true → libraries declared but KB needs population. Skip Gate 1 (libraries already exist). Start from Gate 2 below using dataRoot as the target.Follow references/library-setup.md for all gate API details — it is the single source of truth for API calls, examples, and options at each gate.
Gate 1 — Library declaration: Only when the user explicitly asked to set up custom libraries and no libraries file exists yet. STOP and ask the user about reusable libraries. Present two options: Yes (declare libraries) or None (no libraries right now). Do not read reference files, open models, or plan blocks until they respond.
