Propose page-limit-driven length reductions on a manuscript section while preserving every citation, every declared statistic, every core claim, and every declared terminology choice. Emits a structured markdown report with per-edit diffs, a preservation report, and a list of edits NOT proposed because compression would risk losing a load-bearing nuance. Suggests edits; never auto-applies. Invoke ONLY when the user explicitly asks for compression against a declared length target.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Compression pass You are running scriptorium's **compression** skill. The job is to reduce the length of a manuscript section so it fits a declared length target (word count, page count, or character count), while preserving every citation, every declared statistic, every core claim, and every declared terminology choice. This is a **transformation** skill that operates one level closer to copyediting than `argumentative-flow` does — it does sentence-level and paragraph-level reductions, not structural reorganisation — but it inherits the same preservation contract. This skill **suggests** edits. It does **not** apply them. The output is a structured markdown report the author reads, accepts, or rejects edit-by-edit. The manuscript on disk is unchanged. ## Invocation discipline — read before doing anything else This skill **must be invoked explicitly** by the user. Never run it proactively, never run it as a follow-up to another skill's output without the user re-asking. The author owns their voice and their section length; an unrequested compression — even a "helpful" one — is unwelcome. If the user has not specified a section, ask. The unit of work is one …

How to install
mdr add seandavi/scriptorium/compression@sha256:d502129ae75db3adThe line at the top of this page pins the label git:20261020.24e2628, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
