The record

Purpose: Monostyle is a framework for linting and style-checking documentation against a style guide.
Change-focused checks: Its tools check new or changed content, which the README says makes them fast and allows tools that can have false positives.
Version control: The README says SVN is supported and Git support is experimental.
Customization: The README says Monostyle is not ready-made and its tools and data require customization.
Parser: Monostyle includes its own reStructuredText parser.
Spelling tools: The tools documentation lists checks for spelling, word choice, compounding, abbreviations, homophones, and possessive forms.
Markup and style checks: Listed checks include heading hierarchy, indentation, keyboard shortcut conformity, markup structure, line length, and wrapping.
Natural-language checks: The tools documentation lists limited grammar linting, passive voice detection, article checking, and repeated-word detection.
Project-specific use: The README says Monostyle is customized for the Blender manual.
Setup requirement: When using SVN, the command-line client tools need to be installed.
Spell-check setup: Spell checking requires building a dictionary, and the README says users must confirm its initial build if the dictionary file is missing.
Autofix: The README lists an autofix option that applies autofixes and also updates the working copy for external changes.
Build limitation: The README says running Monostyle does not replace building with Sphinx, and markup errors can cause false negatives.
License: The repository displays a GPL-3.0 license.
