The content is lean and efficient, assuming Claude knows Django basics. No unnecessary explanations of what CSRF or XSS are—just what to configure and why it matters for production.

Every section provides copy-paste ready code snippets with concrete settings, environment variable patterns, and specific commands like `python manage.py check --deploy`. The JavaScript CSRF example is executable.

Clear numbered sections with a logical progression from critical settings to verification. The checklist provides explicit validation steps, and the `check --deploy` command serves as a built-in verification checkpoint before deployment.

Well-organized with clear sections, a summary checklist, and a reference to an external verifier. Content is appropriately scoped for a single SKILL.md without needing deep nesting or excessive external references.

Lists multiple specific concrete security topics: CSRF, CORS, security middleware, ALLOWED_HOSTS, secrets management, and common misconfigurations. These are concrete, actionable areas rather than vague abstractions.

Clearly answers both what (security essentials covering CSRF, CORS, middleware, etc.) and when ('Use when building or reviewing Django apps before production deployment, or when a security audit flags issues'). Explicit trigger guidance is provided.

Includes natural keywords users would say: 'Django', 'CSRF', 'CORS', 'security', 'ALLOWED_HOSTS', 'secrets management', 'production deployment', 'security audit'. These cover both technical terms and common user scenarios.

Highly distinctive with clear niche: Django-specific security. The combination of 'Django' + 'security' + specific security concepts (CSRF, CORS, ALLOWED_HOSTS) creates a unique trigger profile unlikely to conflict with general security or general Django skills.
