Summary by Sourcery

Split PR title validation into separate workflows for semantic checks and spelling checks, adjusting triggers and permissions for safer execution.

New Features:

  • Introduce a dedicated spellcheck_title workflow to validate PR title spelling on pull_request events.

Enhancements:

  • Update the check_pr_title workflow to use pull_request_target with reduced permissions and a new semantic pull request action.
  • Simplify the original title-check workflow by moving spelling validation into its own workflow.

Summary by CodeRabbit

  • Chores
    • Pull request validation now uses a streamlined workflow to check that titles follow the project’s required format.
    • Added automated spelling checks for pull request titles, helping identify misspelled words before changes are reviewed.
    • Validation runs across relevant pull request updates and avoids interrupting checks for excluded pull requests.
    • Checks now use read-only access and run more efficiently, improving the reliability and security of title validation.

Reviewer's Guide

Splits the PR title validation into two workflows: a semantic title check running under pull_request_target with reduced permissions and a separate spelling check workflow running under pull_request, while switching the semantic check action implementation and tightening runner/permissions.

File-Level Changes

Change Details Files
Refactor the PR title validation workflow to use pull_request_target with a semantic title check action and more restricted permissions.
  • Change workflow trigger from pull_request to pull_request_target for title validation events.
  • Rename job from lint to main and add a descriptive job name for validating PR titles.
  • Switch runner image from ubuntu-latest to ubuntu-slim for the main job.
  • Reduce job permissions from statuses: write to pull-requests: read.
  • Replace the conventional-pr-title GitHub Action with amannn/action-semantic-pull_request pinned to a specific commit hash.
.github/workflows/check_pr_title.yml
Extract PR title spellchecking into its own workflow that runs on pull_request events with label-based opt-out.
  • Create a new spellcheck_title.yml workflow triggered on pull_request events including label changes and edits.
  • Limit workflow execution to changes to the spellcheck_title.yml file via paths filter.
  • Define a spellcheck job that runs on ubuntu-slim and respects a skip check PR title label via an if condition.
  • Check out the pull request head ref and repository using a pinned actions/checkout version.
  • Install aspell via apt and run a spellcheck script on the PR title using a project-specific dictionary file, failing the job on misspellings.

Hey - I've found 1 issue, and left some high level feedback:

  • The spellcheck_title workflow is restricted to changes in .github/workflows/spellcheck_title.yml via paths, so it will not run for normal PRs that only change code or titles; consider removing the paths filter if you want title spellchecking to apply to all PRs.
  • The workflow name spellcheck_title.yml is slightly confusing since name is shown in the Actions UI; consider using a descriptive name like Spellcheck PR title instead of the filename.

## Overall Comments
- The `spellcheck_title` workflow is restricted to changes in `.github/workflows/spellcheck_title.yml` via `paths`, so it will not run for normal PRs that only change code or titles; consider removing the `paths` filter if you want title spellchecking to apply to all PRs.
- The workflow name `spellcheck_title.yml` is slightly confusing since `name` is shown in the Actions UI; consider using a descriptive name like `Spellcheck PR title` instead of the filename.

**issue (bug_risk):** The `paths` filter restricts the spellcheck workflow to PRs that modify the workflow file itself, which likely defeats the purpose.

If you want this workflow to validate titles on all relevant PRs (except those explicitly skipped), remove the `paths` restriction or expand it so that typical code or documentation changes also trigger the job.

📝 Walkthrough

Walkthrough

The PR separates semantic pull request title validation from spelling validation. The existing workflow uses a read-only semantic title check. A new workflow uses Aspell and a project dictionary to detect title spelling errors.

Changes

PR title validation

Layer / File(s) Summary
Semantic title validation
.github/workflows/check_pr_title.yml
The workflow supports pull_request_target and path-filtered pull_request events. A read-only main job invokes the pinned semantic pull request title action.
Title spelling validation
.github/workflows/spellcheck_title.yml
A dedicated workflow checks pull request titles with Aspell and the project dictionary. It skips labeled pull requests, checks out the head repository, and fails when misspellings are found.

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

Mergeability Score: 🟡 Moderate · up to d569f

Semantic title validation still does not run when a pull request title is edited, allowing an invalid title to remain accepted until another qualifying event; workflow changes may also trigger duplicate semantic checks. This bounded merge-readiness issue should be fixed or explicitly accepted before merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Remove the paths filters from both title-validation workflows.

Each filter allows the workflow to run only when its own workflow file changes. As a result, normal pull requests—including title-only edits—skip semantic or spelling validation. Remove the paths entries from this workflow and .github/workflows/spellcheck_title.yml so title checks run for all intended pull request events.
