Flowmark

Fast, consistent Markdown auto-formatter for typographic cleanup, normalization, and clean semantic line breaks. Use when creating, editing, or cleaning Markdown; formatting LLM-generated docs; adopting Flowmark in a repository; adding Markdown format scripts or commit hooks; or replacing Prettier or another Markdown formatter.

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.

Format Markdown

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 -).

Use flowmark when it is already on PATH. Otherwise use the fast Rust port with a version-pinned uvx runner (never @latest):

uvx --from flowmark-rs==0.3.2 flowmark --auto FILE

The Python reference remains available when its library API or a newer unported patch is required:

uvx --from flowmark==0.7.3 flowmark --auto FILE

Adopt Flowmark in a Repository

If this skill came from flowmark --skill, run the same runner with --install-skill from the project root to materialize the complete bundle. Then, for a repository-wide migration, Makefile wiring, .flowmarkignore, commit hooks, CI policy, and disabling Prettier or other competing Markdown formatters, read project-setup.md in full before editing.

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: configuration, file discovery, editor setup, the Python library API, and installing this skill (flowmark --install-skill).
