Reviewer's guide (collapsed on small PRs)Reviewer's GuideRefactors the CLI parser auto-detection helper to delegate format detection to the shared auto_detect_parser utility instead of duplicating the parser selection loop, ensuring consistent behavior with the rest of the package and future parser additions.

Warning Review limit reached
More reviews will be available in 52 minutes and 19 seconds. Learn how PR review limits work. Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file). ⌛ How to resolve this issue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

**suggestion (performance):** Re-evaluate iterating over all sample_lines instead of a small subset for auto-detection.
This now scans all of `sample_lines` instead of a fixed first 5, which may be costly if `sample_lines` is large and `auto_detect_parser` is expensive. If `sample_lines` can grow large, either reintroduce a fixed subset (e.g., `sample_lines[:5]`) or guarantee that `sample_lines` is already bounded to a reasonable size upstream.

The
_get_parserhelper insrc/log_analyzer_cli/cli.pyreimplemented the parser-selection loop inline: it iteratedget_all_parsers()and for each parser checked the first 5 sample lines withparser.can_parse(line). Theparserspackage already exportsauto_detect_parser(line)which does exactly this same loop (and iterates all parsers, not just the first match). Replace the inline loop withauto_detect_parser(line)so the CLI's format detection goes through the same code path as the rest of the package and future parser additions automatically become visible to the CLI.Tests: the 11 pre-existing
