Use cases:

before git commit — check staged changes for neuro-slop
post-commit — check the last commit
manual run on a file / line range
pre-commit hook (if the user wires it into .git/hooks/pre-commit)

The skill picks which rule layer to apply (writer / prose-edit / essay-write) based on file path. Default routing is illustrative; configure your own path patterns — see references/routing.md:

fiction project files (e.g. fiction/*.md, novels/**/*.tex) → fiction layer (prose-edit)
non-fiction project files (e.g. essays/*.md, longreads/*.md) → non-fiction layer (essay-write)
generic prose / notes → base writer
code files (.py, .js, .ts, …) → skipped silently
