Lean and efficient — exact file paths and commands with no explaining of concepts Claude already knows; even the note that 'the compiler guides you' is actionable rather than filler.

Copy-paste-ready commands (bin/generate_personhog_proto.sh, pnpm run generate:personhog-proto, cargo build -p personhog-replica) and exact file paths to edit at every layer.

Clearly sequenced Step 0 through Step 4 with an upfront eligibility gate ('If the table is not listed above, stop'), an explicit verify step (cargo build/test), and a final checklist covering batch/database operations.

SKILL.md is an overview with well-signaled, one-level-deep references to real files (database-indexes.md, proto-conventions.md), each linked inline where relevant.

Lists multiple concrete actions — 'eligibility checks, proto definition, code generation for Python and Node.js clients, Rust implementation (storage trait, postgres queries, service handler, router wiring), and index compatibility validation' — rather than vague language.

Explicitly answers both what it does (full enumerated scope) and when to use it via a 'Use when...' clause with three concrete triggers.

Natural trigger phrases a user would say are present: 'adding a new gRPC endpoint to personhog', 'migrating a Django ORM query to personhog', 'extending the personhog service API'.

Narrowly scoped to the personhog service and its specific migration paths, making it unlikely to trigger for unrelated skills.
