Uh filter Claude Code plugin

A Claude Code mod that removes spoken filler words from your prompts, made for voice dictation.

• On send: stripsuh ,um ,uhm ,erm ,hmm ,mm (and their trailing commas) plus stutter repeats like "check check" or "where you where you" before the prompt reaches the model.
• In the terminal prompt box: dictated or pasted text is cleaned as it lands, and a filler you type disappears as soon as you type the space after it.
• Leaves alone: words like "album" or "uh-huh", common real doubles ("that that", "had had"), anything inside backticks or code blocks, pasted code, and slash commands.

To keep a literal "um" in a prompt, put it in backticks.

The desktop app draws its own prompt box, so there the cleanup happens only when you send.

The mod is one hooks module, hooks/register.ts, with two hooks:

• prompt.submit : rewrites the text of every prompt you send, removing fillers and stutter repeats. It skips slash commands and prompts Claude Code sends on its own. Sinceprompt.submit is also a call other plugins can make ($.prompt.submit ), prompts that other plugins submit pass through this cleanup too.
• prompt.edit : in the terminal prompt box, cleans text that lands in one go (dictation, a paste of plain prose) and drops a filler word when you type the space after it. Pasted code and anything inside backticks is left as is.

It reads no files, runs no commands, and sends nothing anywhere.
