Does it support Django Rest Framework (DRF)?

Yes, it specifically checks for SerializerMethodField patterns and other common DRF bottlenecks that cause performance degradation in API endpoints.

How does this skill detect N+1 queries?

It traces data flow from the QuerySet in the view through to loops in templates or serializers to verify if related data triggers additional database round trips.

Can it identify missing database indexes?

Yes, it searches for fields used in WHERE and ORDER BY clauses on large tables that lack 'db_index=True' or entries in the model's Meta.indexes.

Does it offer automatic code fixes?

It provides specific, validated code recommendations such as adding select_related, prefetch_related, or converting loops to bulk operations.

How does it minimize false positives during reviews?

The skill follows a strict 'research-first' approach, requiring confirmation of data volume and hot path execution before reporting any performance issue.

Audits Django codebases to identify and fix critical performance bottlenecks like N+1 queries and unbounded querysets.

The Django Performance Review skill empowers Claude to perform deep, evidence-based performance audits on Django applications. It focuses on identifying high-impact issues that cause real-world scaling problems, such as N+1 queries, memory-exhausting unbounded querysets, missing database indexes, and inefficient write loops. Unlike basic linters, this skill follows a rigorous research-first approach, tracing data flow from views to templates and serializers to ensure every finding is validated and actionable before being reported.
