✨ PR Review

The PR adds a new automation to label PRs authored by Claude or with Claude as a co-author. The implementation looks mostly sound but has regex pattern issues that could affect matching accuracy.

2 issues detected:

🐞 Bug - Applying case-insensitive regex patterns to already lowercased strings is redundant and potentially error-prone.

Details: The regex pattern uses case-insensitive character classes [Cc]laude after already converting the string to lowercase. This redundancy could cause unexpected matching behavior or inefficiency.
File: docs/downloads/automation-library/integrations/claude_code/label_claude_code_by_co_author.cm (14-14)

🐞 Bug - The current pattern may not match all legitimate co-author line formats used in practice.

Details: The regex pattern for detecting co-author lines may be too restrictive and could miss legitimate variations of the "Co-authored-by" format, such as different casing or spacing patterns commonly used in Git commits.

✨ PR Review

The PR adds automation to detect Claude-authored or co-authored PRs and apply labels. The implementation has improved from previous versions, but still contains a pattern matching issue that could result in false positives.

1 issues detected:

🐞 Bug - Substring matching without word boundaries will match unintended usernames containing "claude".

Details: The author matching pattern will match any username containing "claude" as a substring, potentially causing false positives for users like "claudesmith", "mcclaude", or "claudenova".
