Does it support Django Rest Framework (DRF)?

Yes, it specifically looks for SerializerMethodField bottlenecks and suggests efficient alternatives like using annotations in the ViewSet queryset.

Will it report minor style issues?

No, this skill is strictly focused on performance. It prioritizes critical and high-impact issues like memory exhaustion and database lock contention, ignoring micro-optimizations that don't measurably improve speed.

How does this skill detect N+1 queries?

It traces the data flow from views and querysets through to templates or serializers, identifying where related fields are accessed inside loops without proper select_related or prefetch_related calls.

Can it suggest specific database indexes?

Yes, it analyzes fields used in filters and ordering operations on large tables and provides recommendations for adding single-field or composite indexes to the Django model Meta class.

Database Management

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

This skill empowers Claude to perform deep performance audits of Django applications, focusing on high-impact database optimizations. It systematically identifies N+1 query patterns in views and serializers, detects memory-intensive unbounded querysets, suggests missing database indexes, and flags inefficient write loops. Unlike generic linters, it emphasizes rigorous validation—tracing data flow and verifying data volume—to ensure that reported issues represent genuine bottlenecks that affect production performance and scalability.
