Two messages that helped when a skill was called by a name it no longer uses are gone:\n\n- Unknown-skill error: when Claude asks for a skill that does not exist, the error no longer suggests \"a skill from the user's claude.ai account\" under that skill's former namespace. It still suggests a close match, meaning a name that differs by at most two characters. It may now also add text built from plugin load errors and the list of enabled plugins.\n\n- Skill permission prompt: the \"renamed\" case is removed. When checking whether to ask you, the Skill tool no longer looks for an allow rule that names a skill's former name. It used to say that a rule like `Skill(old)` covers the skill's old name, give the new name, and tell you to add `Skill(new)` to allow it without asking.\n\n**Why**\n\nIf your permission rules still name a skill by its old name, Claude Code no longer tells you to update them, so you may be asked for permission without an explanation. When a plugin's skill fails to load, the unknown-skill error can now tell Claude about plugin loading problems instead of only saying the skill is unknown.\n\n- Area: Skills\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5"}
