Conciseness

The 1570-line body pads heavily: 59 code blocks each repeat full import headers (HTTPStatus, msgspec, Controller, MsgspecSerializer re-imported dozens of times), and every rule carries a near-complete "Wrong" twin of the "Correct" example where a 2-3 line diff would convey the same. This is noticeably verbose with many padded sections (anchor 2); it avoids anchor 1 because there is no explanation of concepts Claude already knows, and it falls short of anchor 3's "mostly efficient" given the sheer volume of duplicated boilerplate.

Actionability

Nearly every rule gives copy-paste-ready wrong/correct Python pairs with docs links (e.g. the `@validate`→`@modify` rewrite, the `RedirectTo` open-redirect fix, the `RemoteAddr(runs_before_auth=...)` throttling diff), which is close to anchor 5. Minor gaps hold it at anchor 4: the schemathesis section offers no executable code ("Correct: use `schemathesis`. Check its official docs"), and two "Wrong" snippets contain unrelated bugs (undefined `exc` in the endpoint-body-handling example; `dmr_rf` used in the plain `RequestFactory` example), which muddies the contrast.

Workflow Clarity

This is a best-practice catalog rather than a multi-step pipeline, and its sections progress through an application's concerns in a sensible build order (Installing → Controllers → Redirects → Routing → Error handling → Validation → Auth → Throttling → Testing → Middleware → Configuration → Structure → OpenAPI), each rule stating an unambiguous do/don't with explicit "Limitations" caveats. It sits at anchor 4 (clear, minor gaps) rather than 5 because no section gives validation/verification checkpoints for the riskier flows it touches (e.g. nothing says how to verify a schema after disabling response validation in production), and it stays above anchor 3 since no listed practice is ambiguous.

Progressive Disclosure

There are no bundle files at all: all ~25 rules across 14 topic areas live inline in one 1570-line SKILL.md, and the body's only pointers are external docs URLs. Structure exists (clean topic headers, per-rule headings, "Limitations" callouts), but large self-contained topic clusters (routing, testing, error handling) clearly belong in separate reference files — matching anchor 3 ("content that should be separate is inline") rather than anchor 2, since headers and navigation are present, and short of anchor 4, which expects most bulk content moved out with well-signaled references.

Specificity

The description names the domain ("DMR code") but the actions are entirely generic — "write the best code possible", "all the recommended best practices", "avoiding common mistakes" name no concrete capability (controllers, routing, error handling, testing, etc.). It matches anchor 2 ("Names the domain but actions are minimal or generic"); it does not reach anchor 3 because no specific action is listed, and it is above anchor 1 only because the DMR domain is named.

Completeness

The 'what' is vague ("best DMR code", "best practices", "common mistakes" say little about actual output) and the 'when' is completely absent — no "Use when..." or equivalent trigger guidance, which caps completeness at 3 per the guidelines, and the vague 'what' pushes it to anchor 2. It is above anchor 1 because a recognizable intent (write DMR code correctly) is present.

Trigger Term Quality

The only keyword is the abbreviation "DMR" — the full names "django-modern-rest", "Django", "REST", "API", or "controller" never appear, so a user saying "django REST API" or "django-modern-rest" would not naturally match. This is one minimal, jargon-only keyword, matching anchor 2 ("One or two generic keywords; missing the natural phrases users say") rather than anchor 3, which requires genuinely relevant keyword coverage.

Distinctiveness Conflict Risk

"DMR code" is a narrow niche that would rarely fire for unrelated skills — mostly distinct with only minor overlap risk against general Django/REST skills (anchor 4). It falls short of anchor 5 because there are no explicit distinct trigger phrases, and the unexpanded abbreviation "DMR" could collide with other meanings of that acronym.
