align-colons
AlignmentProse aligns the : separator across dict literals, Args: blocks.
Auto-Fix Rules
Auto-fix rules rewrite source as part of prose format and surface as Severity::Format diagnostics under prose check. Each rule resolves a layout question Prose can answer mechanically (alignment columns, alphabetization order, blank-line counts, collection layout, trailing-comma presence) and emits an Edit list the Pipeline applies between rules. Auto-fix rules never report a violation the binary won't itself resolve.
align-comparisons
AlignmentProse aligns comparison operators vertically across the operands of a multi-line and-chain or or-chain.
align-equals
AlignmentProse aligns the = separator across consecutive single-target assignments and annotated function-parameter defaults.
align-imports
AlignmentProse aligns the import and as keywords across consecutive import statements.
align-match-case
AlignmentProse aligns the post-pattern : across single-expression case bodies inside a match statement.
alphabetize
OrderingProse alphabetizes import siblings, dict-key blocks, and
blank-lines
FormattingProse normalizes
call-layout
FormattingProse explodes a keyword-expressible call carrying more than the inline-argument cap to one keyword argument per line.
collection-layout
FormattingProse splits list, tuple, dict, and set literals into one-entry-per-line layout once they overflow their width, or a dict crosses an entry-count cap.
docstring-expand
DocsProse expands a one-line
docstring-frame
DocsProse drops a multi-line
docstring-wrap
DocsProse wraps multi-line
import-layout
FormattingProse splits an over-budget from ... import ... into a run of repeated-prefix statements packed to the import budget.
signature-layout
FormattingProse normalizes function signatures to one line or one parameter per line, gated by line length and inline-parameter count.
strip-align-padding
FormattingProse strips padding from
strip-trailing-commas
FormattingProse removes trailing commas from inside single-line collections.
unused-future-annotations
FormattingProse removes from __future__ import annotations lines that no longer carry their weight on the target Python version.
