Conciseness

The body is lean, assumes competence, and includes zero explanation of concepts Claude already knows, but the "apply every release, never skip one" imperative is stated roughly four times ("apply all of it", "Never skip a release", "oldest first", "Apply one release at a time"). Fits anchor 4 (minor instances that could be trimmed) rather than 5's "every token earns its place".

Actionability

Fully executable guidance throughout: exact commands ("uv pip show django-modern-rest", "python manage.py dmr_export_schema <schema-path>"), specific lock/requirements file names, a version-range-to-file table, and a versioned llms.txt URL pattern. Copy-paste ready and covers the common cases.

Workflow Clarity

Clear sequence (find versions → bump dependency → apply each prompt oldest-first → verify → report) with explicit validation checkpoints (type checker, tests, "diff the output against the previous schema: only intended changes should appear", symbol search with the completion criterion "none is left") and a stop-and-ask escape hatch. The batch migration even gets a feedback loop, matching the anchor for clear sequence with explicit validation and error recovery.

Progressive Disclosure

The SKILL.md is a concise overview and the heavy per-release migration prompts are split into one-file-per-release in references/, clearly signaled by a linked table; all three referenced files exist and match the links. Pre-0.13 guidance points to external release notes rather than nesting files, so references are exactly one level deep with easy navigation.

Specificity

"Upgrade a project to a newer django-modern-rest (dmr) release" and "Applies the official migration prompt of every release in between, in order" name several concrete actions. Not 5 because coverage has minor gaps (e.g., the verification steps central to the skill go unmentioned); not 3 because it goes well beyond naming the domain with 1-2 generic actions.

Completeness

Explicitly answers both questions: what ("Upgrade a project to a newer django-modern-rest (dmr) release... Applies the official migration prompt of every release in between, in order") and when ("Use when bumping... or when asked to migrate...") with three concrete trigger phrases, in third-person voice. Matches the anchor-5 example structure exactly.

Trigger Term Quality

"bumping the django-modern-rest version", "dependency update breaks imports from `dmr`", and "migrate to a new dmr release" give comprehensive natural trigger phrasings with synonyms (upgrade/bump/migrate) plus both the full package name and its abbreviation. No natural term a user would say is missing for this domain.

Distinctiveness Conflict Risk

A clear niche scoped to a single named package's version upgrades with distinct triggers (bump/migrate/broken imports of `dmr`); virtually no overlap risk with any other skill. Clearly matches the anchor for a distinct niche with minimal conflict risk.
