Conciseness

Dense with operational specifics (exact commands, flags, class names, file paths) and free of generic concept explanations; the explanatory prose present (e.g. historical model registry, single test_* method) justifies non-obvious gotchas rather than padding.

Actionability

Provides copy-paste-ready commands (`sentry django makemigrations <app_name> --empty`, `--migrations --reuse-db --create-db`), a full executable TestMigrations example, and concrete class/constant names (SafeRemoveField, DeletionAction.MOVE_TO_PENDING, SafeDeleteModel).

Workflow Clarity

Sequences are explicit with validation checkpoints — the 'After Generating' list includes sqlmigrate verification and local apply that catches unsafe ops, and column/model deletion are phased with explicit 'Deploy' gates between phases.

Progressive Disclosure

No bundle files exist, so the single self-contained SKILL.md is appropriately organized into clear sections (Commands, After Generating, Guidelines subsections, Resolving Merge Conflicts) with no nested-reference indirection.

Specificity

Lists multiple concrete actions — 'creating migrations, adding/removing columns or tables, adding indexes, or resolving migration conflicts' — matching the score-3 anchor rather than the single-domain score-2 anchor.

Completeness

Explicitly answers both what ('Generate Django database migrations for Sentry') and when ('Use when creating migrations...'), with an explicit 'Use when' clause satisfying the score-3 anchor.

Trigger Term Quality

Uses natural phrases users actually say ('creating migrations', 'adding/removing columns or tables', 'adding indexes', 'resolving migration conflicts') with good coverage across the skill's scope.

Distinctiveness Conflict Risk

The niche is sharply defined — Django migrations specifically for Sentry — making it unlikely to trigger for unrelated skills.
