Each hook has a matcher, a pattern saying which tools or events it applies to. When Claude Code builds a summary of your hooks, it already stopped at limits on the number of hooks, their size and their arguments. It now has a fourth limit, on the combined length of all the matchers. Hitting any of these limits marks the summary as cut off.\n\n**Why**\n\nIf you have a very large hook setup, especially one with long matchers, its summary will be cut off sooner than before.\n\n- Area: Hooks\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
