semantic-compression SKILL.md skillA
semantic-compression from muselinn/musepi is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Re-encode verbose prose into a dense telegraphic register — punctuation as connectives, label frames, verbless assertions — without losing normativity or precision. Use when compressing system prompts, tool/function descriptions, skill bodies, or agent instructions; reducing token count or context bloat; making documentation token-efficient for LLM input; or rewriting text in compressed notation.
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
# Semantic Compression Compression is **re-encoding, not word deletion**. Filtering function words out of an English sentence leaves a damaged English sentence (`System design: efficient process incoming data, multiple sources`). Instead re-frame each claim in a register whose grammar is punctuation and layout — then the function words have no work left and drop out on their own. Target texts are load-bearing: tool descriptions, system prompts, skills. A model executes them cold, with no author present to disambiguate. Compression that forces a guess is a bug, not a saving. ## Procedure 0. **Density gate — check before touching anything.** Two signals, in order: (a) are articles and copulas already near-absent? (b) compress one representative section and measure the token delta. Already in this register (house-style prompt, tool doc, spec) or delta under ~10%? **STOP. Report that it is already dense and keep the original.** Bullet length alone is a weak signal — API literals and enumerations inflate it. Measured on a real house-style tool prompt: 853 → 778 tokens (8.8%), while that pass silently dropped a `NEVER assume …` rule, a throw condition, and a `full-res` detail. On… …

How to install
mdr add muselinn/musepi/semantic-compression@sha256:11e5ee26fccf39d9The line at the top of this page pins the label git:20260823.eb76001, 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.
