Conciseness

The ~220-line body is dense with non-obvious, decision-critical guidance (behavioral vs transport parity, security posture rules, drift accounting, pitfalls) and explains nothing Claude already knows about Django or DRF; the architectural framing that allauth keeps owning account flows is exactly the kind of context Claude lacks. Only one or two reassurance sentences ("This is normal, and it is the right place...") could be trimmed, which does not reach the 4 anchor's 'minor instances of over-explanation'.

Actionability

Quotes: "Add `allauth`, `allauth.account`, `allauth.headless` to `INSTALLED_APPS`", "`XSessionTokenSyncAuth`", "`HeaderJWTSyncAuth`", "`@sensitive_post_parameters`", "Return `NO_STORE_HEADERS` from `dmr.security` in `@modify`". Guidance names exact classes, settings keys, decorators, and an ordered 8-flow sequence, but provides no syntax examples for the dmr constructs it invokes (`Controller` with typed DTOs, `CookieSpec`, `external_path()`), delegating those to the external docs — fitting 'mostly executable guidance; concrete code or commands with minor gaps' rather than the 5 anchor's copy-paste-ready examples.

Workflow Clarity

Quotes: "Migrate one flow at a time, in this order, because later flows depend on being able to log in", "(required gate)", "then run the repository's checks", "Do not mark a flow done until linters pass, tests pass, the client is updated, and the report is updated", plus the Output Checklist. The sequence is explicit with rationale, two required gates act as checkpoints, validation is mandated per flow and at the finish gate, and a final checklist covers the complex process — matching the 5 anchor's explicit validation steps and checklists.

Progressive Disclosure

The body keeps procedure and policy in SKILL.md while all lookup tables (endpoint, MFA, social, auth-class, settings, serializer maps) live in the single one-level-deep reference [references/dj-rest-auth-to-dmr-map.md], which exists in the bundle, is clearly signaled in the required-docs list, and is pointed to twice more by name ("See the settings table in the local map", "See the auth table in the local map"). The reference chains no further files, and the split is appropriate for navigation — matching the 5 anchor.

Specificity

Quotes: "Migrate an existing Django auth API from dj-rest-auth to django-modern-rest", "moving account flows onto django-allauth headless", "rebuilding the transport layer with dmr controllers and auth classes", "replacing dj_rest_auth login/logout/registration/password/MFA/social views and their DRF serializers". Multiple specific concrete actions with comprehensive coverage of the migration scope, in third-person voice; the 4 anchor would require minor coverage gaps, which are absent.

Completeness

Quotes: "Migrate an existing Django auth API from dj-rest-auth to django-modern-rest..." (what) and "Use when replacing dj_rest_auth login/logout/registration/password/MFA/social views and their DRF serializers." (when). Both what and when are answered explicitly with concrete trigger phrases, matching the 5 anchor exactly; the 4 anchor's 'when could be more explicit' does not apply.

Trigger Term Quality

Quotes: "Django auth API", "dj-rest-auth ... dj_rest_auth", "login/logout/registration/password/MFA/social", "DRF serializers". Good natural keyword coverage including both the package and module spellings, but common synonyms such as the legacy "django-rest-auth" package name and "Django REST Framework auth" phrasings are missing, matching the 4 anchor rather than the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The description pins a named-source (dj-rest-auth) to named-target (django-modern-rest) migration niche with distinct triggers, so it is clearly distinguishable even from a sibling DRF-migration skill; minimal conflict risk, matching the 5 anchor.
