# output-hygiene Surface pass over text an agent wrote. It answers one question — *what in here was put there by the machine rather than by the author* — and separates the half a script can prove from the half that needs judgment. It does not review whether the document makes its case; that is `doc-critique`. There is no cryptographic watermark in Claude's text output, and this skill does not pretend to remove one. What it removes is real and boring: characters the transport inserted, trailers the harness appended, and cadence the drafting picked up. ## How to respond 1. **Name the target medium before reading a word of the text.** Markdown document, plain text, commit message, code comment, web form, CSV. The medium decides whether a class is a defect at all: a curly apostrophe is correct in Markdown prose and a bug in a commit message; an em dash is punctuation in an essay and a tell at four per paragraph. State the medium in the first line of the report. 2. **Run the script first, and read its output before reading the draft.** It localizes every mechanical finding, so the model pass only has to look at prose. ``` python3 ${CLAUDE_SKILL_DIR}/scripts/scrub.py <path> --medium <medium> --json ``` In non-Claude IDEs the same file is at a plain relative path: `python3 scripts/scrub.py <path> --json`. Pass the medium from step 1 — `markdown` (the default), `html`, `plaintext`, `commit`, `code`, `csv` — because it decides whether typographic punctuation is repor
