Fails a pull request or a push to the default branch that carries AI session links or AI co-author lines.
Summary by CodeRabbit
Chores
Added an automated check for pull requests that flags specified AI-related links, attribution lines, and emoji in titles, descriptions, or commit messages. When a match is found, the check reports it and fails; otherwise, it reports that no matches were found. The check runs when pull requests are opened, edited, updated, or reopened, and when changes are pushed to the main branch.

distinguishable AI identities rather than provider-name substrings anywhere in a
co-author line; preserve detection of the other listed AI-generated markers and
ensure human attributions such as “Devin Smith <devin@example.com>” are not
rejected.

Walkthrough
The new GitHub Actions workflow checks pull request titles, bodies, and commit messages for configured AI-related patterns. It reports matches and fails when it finds one.
Changes: AI-line workflow check
Layer / File(s)
Summary
Workflow triggers and job setup .github/workflows/no-ai-lines.yml
The workflow runs on specified pull request events and pushes to main. It sets read-only permissions and provides event and repository values to the check.
Pattern detection and result .github/workflows/no-ai-lines.yml
The check scans pull request titles, bodies, and paginated commit messages. For pushes, it scans commit messages from the event payload. It fails pull requests with more than 250 commits and fails when it finds a configured match.
The check can miss some AI-attributed lines, such as generated-with lines for non-Claude tools and ChatGPT share links. It can also reject valid human co-author lines whose names contain a listed word. This is a CI-only check with no runtime impact, but the pattern should be tightened before merge so it enforces its stated purpose reliably.

Review details
Before / after behavior
observed — Modified behavior in .github/workflows/no-ai-lines.yml: Adds the no-ai-lines workflow, its pull-request and main push triggers, read-only permissions, and environment values for the repository, event, and pull-request number.
observed — Modified behavior in .github/workflows/no-ai-lines.yml: Adds a shell check that matches configured AI-related text case-insensitively, reports matching lines, and records a failure when a match is found.
observed — Modified behavior in .github/workflows/no-ai-lines.yml: For pull requests, fails if the commit count exceeds 250; otherwise checks the title, body, and paginated commit messages. For other workflow events, checks commit messages from the event payload. Exits unsuccessfully if any match was recorded, or reports that none were found.

Match generated lines for the listed AI tools.
Generated with Copilot and Generated by Gemini do not match this pattern. The workflow therefore accepts generated-with lines for tools already named in the co-author pattern. Include those tool names in the generated-line alternative.

Update the generated-line alternative in the banned pattern used by the workflow
so it matches generated-with/by lines naming the AI tools already listed in the
co-author alternative, including Copilot and Gemini.

Do not match human co-authors by name substring.
Co-authored-by: Devin Smith <devin@example.com> matches devin, even when the co-author is a person. The check then fails and asks the contributor to remove a valid attribution. Match distinguishable AI identities instead of arbitrary name substrings.

Match ChatGPT session links.
A chatgpt.com/share/<id> link identifies a shared ChatGPT conversation, but this pattern accepts it. (help.openai.com) Add the supported session-link formats to the pattern.
