name	unity-broken-refs-triage
description	Use when prefabs/scenes show Missing Script or pink materials: triage broken script and asset GUID references and decide fix order.

Broken references triage

Discovery

1. get_broken_script_refs — Missing Script on prefabs/scenes
2. get_broken_asset_refs — any missing GUID refs (mats, controllers, …)
3. find_references — who still points at a deleted asset GUID/path
4. get_meta_for_asset — confirm GUID still exists for survivors

Fix order

1. Restore or reassign scripts (GUID in .meta must match YAML m_Script).
2. Fix materials/shaders (list_materials_using_shader).
3. Fix Animator/Timeline refs (list_animator_controllers, list_timeline_playables).
4. Re-run both broken-ref tools until empty.

Prompts

• "Which prefabs have missing scripts?"
• "List broken asset GUID references"
