Review Pr

Highcharts PR Review

Use this skill when reviewing a PR, branch diff, staged diff, or selected files.

Inputs

• Optional scope: file paths, commit range, or branch.
• If no scope is provided, review git diff and git diff --staged.
• If PR metadata is available, review labels/tags and the PR description before reviewing code.

Checklist

1. Read context first:

• CODE_REVIEWS.md
• CONTRIBUTING.md
• repo-guidelines.md
• ts/DOCLETS.md
• samples/README.md
• test/readme.md

2. Check PR metadata when available:

• Verify labels/tags are correct.
• Review the PR description against CONTRIBUTING.md#writing-content-for-the-changelog.
• Confirm changelog labels/product tags are present when needed, and that the first paragraph is suitable changelog text.

3. Verify correctness:

• Edge cases, null/undefined handling, backward compatibility, API consistency.

4. Verify performance and size:

• Avoid O(n^2) loops in hot paths, avoid extra redraw/reflow, keep bundle/core impact low.

5. Verify docs/doclets/types:

• New/changed options and public types should have doclets and type coverage.
• Flag undocumented behavior changes.
• For doclet wording and style, apply the api-ref-tone skill.

6. Verify tests:

• Require unit/regression tests.
• Prefer adding to existing test files.
• If not automatable, require a manual test plan.

Output format

For each finding:

• Severity: Critical | High | Medium | Low
• Location: path:line
• Issue
• Suggestion

Then provide:

1. Verdict: Ready / Needs changes / Needs discussion
2. Blocking issues
