Documentation

README

Excerpt

Compress the target file. Preserve all meaning. Reduce tokens.

Rules:

Drop: articles (a/an/the), filler (just/really/basically), hedging, pleasantries.
Fragments OK. Short synonyms (big not extensive, fix not implement a solution).
Arrows for causality (X → Y).
Abbreviate common terms (DB/auth/config/req/res/fn/impl/env/deps).
Preserve EXACTLY: code blocks, URLs, file paths, commands, headings, dates, versions, technical terms.
Only compress prose. Never touch code.

This is the opening of the README. Read the full README on GitHub.
