Unity Broken Refs Triage

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"
