+            Review this PR focusing on:
+            1. Accuracy - technical content is correct for the Mapbox APIs and SDKs referenced
+            2. Skill structure - each skill has a valid frontmatter block (name, description, triggers, content) matching the schema in CONTRIBUTING.md
+            3. Clarity - guidance is actionable and unambiguous; code examples are complete and runnable
+            4. Consistency - tone, formatting, and depth match existing skills in the repo
+            5. Scope - skills stay focused on their stated topic; no unnecessary overlap with other skills
+
+            Do NOT suggest adding more skills beyond what the PR introduces.
+            Do NOT flag minor prose style preferences as issues.
+
+            Provide detailed inline comments for specific issues.
