What it does
Cdrf Expert is an agent skill from vintasoftware/django-ai-plugins. Expert guidance for Django REST Framework class-based views using Classy DRF (https://www.cdrf.co). Use when selecting or debugging APIView, GenericAPIView, concrete generic views, mixin combinations, or ViewSet/GenericViewSet/ModelViewSet behavior; tracing method resolution order (MRO); understanding which method to override (create vs performcreate, update vs performupdate, destroy vs performdestroy, getqueryset, getserializerclass); and comparing behavior across DRF versions. Do not use for function-based…
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/class-selection-matrix.md`, `references/lifecycle-and-overrides.md` and `references/mro-debugging-playbook.md`).
It sits in Backend & APIs, covering Backend development, GraphQL and Debugging. It works with Django, FastAPI, Flask and GraphQL. The repository describes itself as: A collection of AI Skills specialized in Django Backend development.
When your agent uses it
- Debugging APIView
- Concrete generic views
- Mixin combinations
- ViewSet/GenericViewSet/ModelViewSet behavior
Example prompts
- “/cdrf-expert”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- If cdrf.co is unavailable, state that limitation and fall back to DRF official docs and installed source code.
- If the user cannot provide DRF version, provide a version-agnostic path and clearly mark assumptions.
- If multiple override points appear valid, recommend the narrowest hook first and explain tradeoffs.
What it can do on your machine
Read from SKILL.md and the folder at commit b8af268. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
cdrf.co
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cdrf Expert loads about 859 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 156 tokens; SKILL.md has 343 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 343 words (~859 tokens).
“Map the user request to one or more categories:”
- name
- cdrf-expert
Files
SKILL.md and 4 other files (references) in skills/cdrf-expert of vintasoftware/django-ai-plugins.
