ci: post ESLint's findings on the lines a pull request adds as review comments - #67
Conversation
… comments A pull request from a branch of this repository that changes src/, the ESLint config, package.json or this workflow runs ESLint with the lint script's pattern on its head, and each finding on an added line becomes a review comment. The job never fails and is not a required check; the build job's lint step is unchanged. Forks and Dependabot are skipped, since their token cannot post a review. CONTRIBUTING.md describes it.

**Untrusted lint code gets write access**
When a same-repository pull request changes ESLint configuration or a dependency to execute attacker-controlled JavaScript, the ESLint action runs that JavaScript while receiving `GITHUB_TOKEN` with `pull-requests: write`, allowing it to make unauthorized pull-request API changes, including altering reviews or comments.
Run head-controlled linting without the write token, and keep credentialed comment posting in a step that does not execute pull-request-controlled code.

**ESLint comments are skipped or stale**
When a pull request has more than 300 changed files with all matching paths after the first 300, or reverts its last matching file after a run has posted comments, the `paths` filter skips the workflow, so the first case gets no ESLint comments and the second leaves findings from the earlier run visible.
Remove the `paths` filter so the workflow runs on pull-request updates and can post or reconcile comments.

**Dependabot findings are not posted**
When a maintainer triggers an event on a Dependabot pull request from a branch in this repository, the actor check admits the job, which runs the pull request's packages and ESLint config, but the pull request's read-only token prevents reviewdog from posting findings.
Gate the job on the pull request author and skip Dependabot pull requests, rather than relying on who triggered the event.

**Retargeted PRs retain stale comments**
When a maintainer changes a pull request's base branch, the workflow does not run on `edited`, so reviewdog never recalculates or removes the old review comments; after retargeting, comments remain associated with the previous base's added-line diff.
Include the `edited` pull-request event so reviewdog can refresh comments after a base-branch change.

The workflow now runs on every pull request from a branch of this repository. edited is added for a change of base branch, so the comments follow the new diff. A title or body edit skips the job, and its run takes a concurrency group of its own, so it cannot cancel a lint run in progress. The job's comment gave the wrong reason for skipping Dependabot: the permissions key raises a Dependabot run's token, so it could post. Dependabot changes manifests and never a line under src/, and skipping its runs keeps a newly bumped ESLint package from running with this token.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Keep skipped Dependabot runs out of the lint concurrency group.
If a maintainer starts lint on a Dependabot pull request and Dependabot updates that pull request before lint finishes, the new workflow run cancels the maintainer’s run. The job condition then skips the new run, so neither run posts findings. Give Dependabot-triggered runs a unique group, as this expression already does for title- and body-only edits. GitHub applies this concurrency setting to workflow runs, not only to jobs that pass their conditions. (docs.github.com)
