The content is lean and efficient. It assumes Claude knows Django, migrations, and Python. Every section provides only the specific Sentry-relevant details (e.g., `db_default` instead of `default`, `SafeDeleteModel`, `historical_silo_assignments`) without explaining basic concepts.

Provides concrete, executable commands (`sentry django makemigrations`, `bin/update-migration`), specific class/method names (`SafeRemoveField`, `DeletionAction.MOVE_TO_PENDING`), exact file paths (`src/sentry/db/router.py`), and copy-paste ready bash commands. Every guideline is specific and directly usable.

Multi-step processes (deleting columns, removing models) are clearly sequenced with numbered steps and explicit deploy checkpoints between phases. The 'After Generating' section includes a validation step (`sqlmigrate` to verify SQL, `migrate` to trigger safety checks). The two-phase model removal process has clear phase boundaries with deploy gates.

For a skill with no bundle files, the content is well-organized with clear section headers (Commands, After Generating, Guidelines with subsections). The length is appropriate — not monolithic — and each section is focused. No external references are needed given the scope, and the structure supports quick scanning.

Lists multiple specific concrete actions: generating Django database migrations, creating migrations, adding/removing columns or tables, adding indexes, and resolving migration conflicts.

Clearly answers both 'what' (generate Django database migrations for Sentry) and 'when' (explicit 'Use when' clause covering creating migrations, adding/removing columns or tables, adding indexes, resolving migration conflicts).

Includes strong natural keywords users would say: 'Django', 'migrations', 'columns', 'tables', 'indexes', 'migration conflicts', 'Sentry'. These are terms developers naturally use when working with database schema changes.

Highly distinctive due to the combination of 'Django', 'Sentry', and 'database migrations' — this is a clear niche that is unlikely to conflict with other skills. The Sentry-specific scoping further reduces overlap risk.
