ci: add no-ai-lines check by ricardofrantz · Pull Request #28 · openfluids/linstabpy

ricardofrantz · 2026-11-02T21:42:44Z

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
- Pull request titles, descriptions, and commit messages—as well as commit messages pushed to the main branch—are now checked for configured AI-related markers.
- When a marker is found, the automated check reports the affected text and fails.
- Pull requests with more than 250 commits also fail the check because not all commits can be reviewed.

Match specific AI co-author identities.
Cover generated lines for the added AI tools.

Inline comments:
Review comments at @.github/workflows/no-ai-lines.yml:
- Line 29: Update the `banned` pattern so the co-author rule matches known AI
identities or email addresses rather than arbitrary name substrings such as
“devin”; preserve the existing detection of other banned AI attribution formats.
- Line 29: Update the generated-line alternative in the `banned` pattern to
recognize supported AI tool names, including ChatGPT and Gemini, so “Generated
with” and “Generated by” lines using those names are caught. Preserve the
existing matching behavior and tool coverage in the co-authored-by alternative.

Walkthrough

Adds a GitHub Actions workflow that checks pull request titles, bodies, and commit messages, plus commit messages on pushes to main, for configured AI-related patterns. It reports matches and fails the job if it finds any. Pull requests with more than 250 commits also fail.

Changes: AI-related line checks

Layer / File(s)	Summary
Workflow triggers and matcher setup `.github/workflows/no-ai-lines.yml`	The workflow defines triggers and permissions, provides GitHub context, and configures a case-insensitive matcher for AI-related patterns.
Content checks and result reporting `.github/workflows/no-ai-lines.yml`	For pull requests, the workflow checks titles, bodies, and paginated commit messages. It rejects requests with more than 250 commits. For pushes to `main`, it checks commit messages from the event payload. The workflow reports matches and fails if it finds any.

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

Change: Feature

Merge Risk: Low · up to db559

The check is mergeable with follow-up, but its matcher should be tightened because it can both reject legitimate co-authors and miss common AI-related content.

Architecture risk: Low · up to db559

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

Architecture concerns
No architecture-level concerns identified.

Review details

Before / after behavior

observed — Modified behavior in .github/workflows/no-ai-lines.yml: Adds the no-ai-lines workflow, triggered by specified pull request events and pushes to main, with read-only repository and pull-request permissions.
observed — Modified behavior in .github/workflows/no-ai-lines.yml: Adds an Ubuntu job that supplies GitHub context through environment variables and configures patterns for detecting AI-related lines.
observed — Modified behavior in .github/workflows/no-ai-lines.yml: Adds a case-insensitive matcher that reports matching lines and records a failure without immediately stopping further checks.
observed — Modified behavior in .github/workflows/no-ai-lines.yml: For pull requests, checks the title and body, rejects requests with more than 250 commits, and checks paginated commit messages. For pushes, checks commit messages from the event payload.

Full details: Title check

Explanation

The title "ci: add no-ai-lines check" matches the main change. The PR adds a GitHub Actions workflow that fails pull requests or pushes to main when commits or text contain AI session links, AI co-author lines, or generated-with lines. The title names the change type and the new check, so it is specific and clear.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Description check

Explanation

The description states the purpose in one sentence: it fails a pull request or a push to the default branch that carries AI session links or AI co-author lines. It does not follow the repository template. It lacks the Summary paragraph, the Changes list, the Verification section with commands, the Checklist, and the Related issues section. The description is short but gives the core intent, so it is mostly incomplete rather than off-topic.

Resolution

Expand the description to follow the repository template. Add a Summary paragraph that explains what the workflow checks and why. Add a Changes list with the workflow file .github/workflows/no-ai-lines.yml and its behavior. Add a Verification section that shows how the workflow was tested, such as a test PR or a local run. Complete the Checklist items that apply. Add a Related issues or context entry, or state that none exists. Keep the SPDX header from the template.

Cover ChatGPT and Gemini shared links.

A PR body or commit message containing only a ChatGPT or Gemini shared link can pass the workflow because the pattern recognizes only Claude session links. Update the workflow pattern. No corresponding script or test file exists at this head.

Match specific AI co-author identities.

The new devin alternative also matches Co-authored-by: Devin Smith <devin@example.com>. The workflow then rejects a commit that credits a human. Match known AI identities or email addresses instead of arbitrary substrings.

Cover generated lines for the added AI tools.

Generated with ChatGPT and Generated by Gemini do not match the generated-line alternative. These lines therefore pass despite the documented check. Extend that alternative to cover the supported AI tools.
