Lists multiple specific concrete security actions: authentication, authorization, CSRF protection, SQL injection prevention, XSS prevention, and secure deployment configuration. These are concrete, actionable security domains.

Describes WHAT (security best practices for Django) but completely lacks a 'Use when...' clause or any explicit trigger guidance for WHEN Claude should select this skill. Per rubric guidelines, missing explicit trigger guidance caps completeness at 2, and this has no 'when' component at all.

Contains relevant technical terms (CSRF, SQL injection, XSS, Django) that security-focused users would use, but missing common variations like 'security audit', 'vulnerability', 'secure coding', or English equivalents that users might naturally say.

Django-specific focus provides some distinctiveness, but could overlap with general web security skills, Python security skills, or other framework security skills. The security topics listed are common across many web frameworks.

The skill is comprehensive but includes some unnecessary explanations (e.g., comments like '# CRITICAL: Never use True in production' and verbose section introductions). Some sections could be tightened, though most code examples are lean.

Provides fully executable, copy-paste ready code examples throughout. Each security topic includes concrete Python/Django code with proper imports, settings configurations, and implementation patterns.

While individual security configurations are clear, there's no explicit workflow for implementing security holistically. Missing validation steps for verifying security configurations are properly applied (e.g., how to test CSRF is working, how to verify headers are set).

Content is well-organized with clear sections and a summary checklist, but it's a monolithic document (~400 lines) that could benefit from splitting detailed topics (API security, file uploads, CSP) into separate reference files with links from the main skill.
