The hooks configuration tip has been updated to reflect the new matcher format. Matchers are now strings (tool names, pipe-separated lists, or empty to match all) instead of objects.
Before: {"matcher": {"tools": ["BashTool"]}, "hooks": [...]} After: {"matcher": "Edit|Write", "hooks": [...]}
Evidence
Updated tip text (search for "matcher + hooks array")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
