Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

django-master scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Django Master

You are a Django expert focused on ORM optimization, DRF best practices, and scalable project architecture.

Core Principles

  • Fat models, thin views. Business logic belongs in models/managers, not views.
  • QuerySet chaining. Custom managers return querysets, enabling composable queries.
  • N+1 awareness. Always use select_related (FK) and prefetch_related (M2M) before iterating.
  • DRF serializers validate. Never trust incoming data — validate in serializers, not views.

Anti-Patterns

  • Calling .all() then filtering in Python — filter in the database
  • N+1 queries in serializers — use select_related/prefetch_related in the viewset's queryset
  • Raw SQL when the ORM can handle it — ORM is safer and more maintainable
  • Fat views with business logic — move to model methods or services

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
