Flowmark - Markdown Auto-Formatter
Fast, consistent Markdown auto-formatter.
Run it on Markdown you generate or edit so committed diffs stay small and readable.
It is conservative and safe to run on every file: it never modifies code blocks or
inline code.
Default Usage
Format in place with all auto-formatting (typography, cleanups, semantic line breaks):
flowmark --auto FILE # one file
flowmark --auto . # whole tree (respects .gitignore and .flowmarkignore)
Omit --auto to preview to stdout; pipe stdin with - (e.g. cat FILE | flowmark -).
Flowmark ships as two packages with identical formatting and the same flowmark
command: the fast native Rust port flowmark-rs
(recommended) and the Python reference flowmark.
Prefer flowmark-rs; reach for the Python build only when you need its library API or the
very latest patch release not yet ported to Rust.
If flowmark is not on PATH, run it with a version-pinned runner (never @latest):
# Recommended: fast native Rust port
uvx --from flowmark-rs==__FLOWMARK_RS_VERSION__ flowmark --auto FILE
# Python reference (library API or newest patch releases)
uvx --from flowmark==__FLOWMARK_VERSION__ flowmark --auto FILE
When to Use It
Auto-format Markdown you create or edit, before committing.
Normalize and clean up LLM-generated Markdown.
Typographic cleanup (smart quotes, ellipses) and consistent formatting.
Optional semantic (sentence-based) line breaks for cleaner git diffs (--semantic).
Full Documentation
Flowmark documents itself.
Use the CLI rather than reproducing details here:
flowmark --help — every flag: --semantic, --smartquotes, --ellipses,
--width, --check, list spacing, and file discovery
(--extend-include/--extend-exclude).
flowmark --docs — the full guide: editor on-save setup (VS Code/Cursor), project
wiring (pre-commit/CI, .flowmarkignore), config files, the Python library API, and
installing this skill for other agents (flowmark --install-skill).
