CodeRabbit writes a summary into the pull request description and rewrites it on every review. Its wording on #82 fails the prose lint (SemicolonUsage, RestatementMarkers), and an edit to it is lost on the next review.

lint-prose.sh now drops the block between CodeRabbit's auto-generated comment markers before linting the description. Only a block closed by a marker of its own kind is dropped. After an opening marker with no closing one, the rest of the description is still linted. The block's lines are blanked, so Vale's line numbers still match the description, and a trailing carriage return is dropped first so CRLF descriptions match too.

Checks

Run against a description through MERGE_REQUEST_DESCRIPTION:

Description Result
Clean text, then a CodeRabbit block with findings Passes
A finding before the block Fails
A finding after the block Fails, on the line it has in the description
CRLF line endings, then a CodeRabbit block with findings Passes. The version before this fix fails
An opening marker with no closing one Fails
An unclosed block, then a closed block of another kind, with a finding between them Fails. The previous version passes
A closed release notes block, then a closed tweet message block, both with findings Passes

Run on both mawk and gawk. shellcheck passes.

CodeRabbit writes a summary into the pull request description and rewrites
it on every review, so its wording can fail the lint on a push that changed
no prose. Nobody here can fix it for good, because the next review undoes the
edit. The block between its markers is now dropped before linting. A block
missing its closing marker is still linted.

Walkthrough

Before linting merge request descriptions, the script filters closed CodeRabbit-generated comment blocks. It normalises marker matching for carriage returns, preserves line numbers, and retains content from an unmatched opening marker.

Changes: Merge request prose linting

Layer / File(s) Summary
Filter generated comment blocks
.gitlab/scripts/lint-prose.sh
The script strips trailing carriage returns before matching markers and blanks the lines of each closed block. If a closing marker is missing, the description remains unchanged from the opening marker onward.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: Low · previous review 641c9

Merge request descriptions with a closed CodeRabbit block are now excluded from prose lint, and findings after the block keep their original line numbers. In the unusual case of an unclosed block followed by a different closed block, authored text between them is silently skipped. The risk is small and limited to the lint check, so the PR can merge with a follow-up.

Review comments at @.gitlab/scripts/lint-prose.sh:
- Line 134: Update the auto-generated comment filtering rule in the script’s awk
flow to emit a blank line for each removed line instead of skipping it,
preserving original line positions for Vale diagnostics while continuing to
exclude the block’s text.
- Line 132: Update both generated-comment marker patterns in the awk script to
accept an optional carriage return before the end of the line, so CRLF input
still matches both markers and preserves the existing block-handling behaviour.

A description edited on GitHub can end its lines in CRLF. With the carriage
return in place neither marker matched, and the summary was linted again.
Each line now loses a trailing carriage return first. The summary's lines are
blanked instead of removed, so the line numbers Vale reports after it match
the description.

Any CodeRabbit closing marker ended the block, so a release notes block left
open was closed by the next block's marker, and the text between the two was
blanked instead of linted. The opening marker's kind is now recorded, and only
a closing marker of the same kind ends the block.
