Prompt submission is the moment you send a prompt, before Claude works on it. That check now applies an extra test to each mod, so some mods that counted before are no longer counted.\n\n**Why**\n\nThis may change when sending a prompt waits for hooks to run.\n\n- Area: Plugins\n- Names: `prompt.submit`, `UserPromptSubmit`\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
