Lists multiple specific concrete actions: designing Django ORM models, handling silos, replication, relocation, foreign key type selection, and refactoring silo placement. These are concrete, domain-specific capabilities.

Clearly answers both 'what' (design Django ORM models following Sentry architectural conventions for silos, replication, relocation, and foreign keys) and 'when' (explicit 'Use when...' clause with multiple trigger scenarios, plus explicit exclusions for what it's NOT for).

Excellent coverage of natural trigger terms including 'add a Django model', 'create a model', 'new database table', 'store this data in the DB', 'I need to track Y', and 'model for [feature]'. These are phrases users would naturally say, covering both technical and casual variations.

Highly distinctive — scoped specifically to Django ORM models in the Sentry codebase, with explicit exclusions for Pydantic models, dataclasses, ML models, and Protobuf. This makes it very unlikely to conflict with other model-related skills.

The skill is mostly efficient and covers genuinely non-obvious Sentry-specific conventions, but some sections are slightly verbose — e.g., the soft delete and constraints sections explain Django concepts Claude likely knows, and phrases like 'The wrong way to think about it' add editorial weight without actionable value. Overall it respects Claude's intelligence but could be tightened by ~20%.

The skill provides a complete, executable model skeleton with correct imports, concrete field examples (FlexibleForeignKey vs HybridCloudForeignKey with exact syntax), a decision table for relocation scopes, and specific file path conventions. The guidance is copy-paste ready and leaves no ambiguity about what to write.

The skill clearly sequences the four design decisions that must be made before writing fields, explains their coupling, and provides an explicit post-design checklist (generate migration, wire outboxes, update exports). The 'After the model is designed' section acts as a validation checkpoint ensuring downstream steps aren't skipped.

The skill cleanly delegates to three other skills (generate-migration, hybrid-cloud-outboxes, hybrid-cloud-rpc) at the top and bottom, keeping the body focused on model design decisions. References are one level deep, clearly signaled, and contextually placed. For a standalone skill with no bundle files, the structure is well-organized with logical sections.
