Conciseness

The body is dense and assumes Claude's competence — no basic Django/OpenAPI concept explanations, every rule is library-specific with exact names like 'parsed_body', 'Body[UserModel | None]', 'validate_responses'. It falls short of anchor 5 only through minor redundancy: roughly eight Review-checklist items restate Non-negotiable rules from the same document (parsed_* names, concrete_views subclassing, as_view ignoring throttling=/auth=, dmr.routing.path, dmr_rf/dmr_client), and the docs-loading bullets list the same llms.txt URL twice under 'index' and 'everything at once'.

Actionability

Fully concrete guidance throughout: executable code snippets ('class UserController(Controller[MsgspecSerializer]): def post(self, parsed_body: Body[UserModel]) -> UserModel', the APIError raise, the concrete_views path(...) routing), exact commands ('uv pip show django-modern-rest', 'python manage.py check', 'python manage.py dmr_export_schema <path>'), and precise names for parameters, settings, serializers, and fixtures. Not a 4 because there are no missing key details for the common cases the body covers; full correct/wrong examples are correctly delegated to the reference files.

Workflow Clarity

The 4-step Workflow is clearly sequenced with a concrete verification checkpoint (step 4: 'run python manage.py check, the project's type checker, and tests... run python manage.py dmr_export_schema <path> and review the diff') and a review checklist for complex work. It sits at 4 rather than 5 because the anchor-5 example includes an explicit error-recovery feedback loop ('If errors: fix and re-validate'), which this workflow omits — it states what to verify but not what to do when verification fails.

Progressive Disclosure

Clear overview with well-signaled, one-level-deep references: the Quick reference table maps each topic to a real bundle file (all seven references/*.md files exist, each linked with a rule count and topic description), the essential 'Non-negotiable rules' stay in SKILL.md while full rules with correct/wrong examples live one level deep, and reference files link only back to SKILL.md and to external docs rather than nesting further. Not a 4 because navigation is complete and nothing that belongs in a separate file is inlined.

Specificity

Concrete actions are enumerated: 'Write django-modern-rest (dmr) code with the recommended patterns, covering controllers, routers, typed DTOs with msgspec or pydantic, auth, throttling, error handling, OpenAPI, and tests' plus 'when reviewing dmr code for mistakes' — comprehensive coverage of the framework's areas with no notable gaps. Not a 4 because the anchor-4 example implies minor coverage gaps, while this lists the full surface (write and review across all major subsystems).

Completeness

Both what ('Write django-modern-rest (dmr) code with the recommended patterns, covering controllers, routers, typed DTOs...') and when ('Use whenever a project depends on django-modern-rest, imports `dmr`, or asks for a typed Django REST API, and when reviewing dmr code for mistakes') are explicit with concrete trigger phrases — a direct match for the anchor-5 example.

Trigger Term Quality

Triggers include the natural detection points users would actually hit: 'a project depends on django-modern-rest', 'imports `dmr`', 'asks for a typed Django REST API', and 'reviewing dmr code'. Both the package name and import alias (the domain's equivalent of a file extension) are present; no common natural phrasing is missing. Not a 4 because anchor 4 expects a few absent natural terms, and none are apparent for this domain.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: the package name 'django-modern-rest' and import name 'dmr' are unambiguous and unlike any sibling skill. Minor theoretical overlap exists only via the generic phrase 'typed Django REST API' (django-ninja could also match), but the dominant triggers are exact, keeping conflict risk minimal; not enough to drop to 4, which requires notable overlap with closely related skills.
