80%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A dense, practical reference: executable code throughout, concern-oriented tables, and proper offloading of protobuf/testing detail into real reference files. Its main gaps are the absence of an explicit sequenced workflow with validation checkpoints for Build/Review modes, and some duplication between the topical sections and the 'Common Mistakes' table.
Suggestions
Add a short numbered Build-mode workflow (write proto → generate code → implement server with interceptors + health → test with bufconn) with a verification checkpoint after codegen and after implementation, which would raise workflow clarity.
De-duplicate guidance between the topical sections and the 'Common Mistakes' table — keep the table to mistakes not already covered above (e.g., drop the reflection/deadline rows repeated verbatim) to recover token budget.
In the Testing section, show one inline bufconn test skeleton (setup → call → assert status code) so the core validation loop is visible without opening references/testing.md.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean — tables, short code, and rationale clauses that justify non-obvious rules ('a raw `error` becomes `codes.Unknown`, telling the client nothing actionable') rather than padding. Not a 5 because of noticeable redundancy: reflection, deadlines, raw errors, bare types, and health checks each appear in both their section and again in the 'Common Mistakes' table. Not a 3 because no section teaches concepts Claude already knows. | 4 / 5 |
Actionability | Copy-paste-ready code for server setup with chained interceptors, GracefulStop-with-timeout shutdown, a complete interceptor function, a fully-specified grpc.NewClient call with retry/load-balancing JSON, and status.Errorf error mapping — plus install commands and a concern→package quick reference table. Coverage spans the common cases; nothing is pseudocode. Not a 4 because there are no missing key details. | 5 / 5 |
Workflow Clarity | The Body's sections imply a build order (proto → server → client → errors → streaming → testing) and 'Modes' state intent, but there is no explicit sequence for Build mode and no validation checkpoints beyond a general recommendation to test error status codes. Matches anchor 3: sequence present but implicit, checkpoints missing. Not a 4 because a newcomer to a 'Build mode' task gets no ordered steps with verify points; not a 2 because the topic organization itself is coherent and each section's guidance is self-contained. | 3 / 5 |
Progressive Disclosure | SKILL.md is a well-structured overview carrying core guidance, with deep material correctly offloaded to one-level-deep references that both exist and are clearly signaled at their point of use ('[Proto & code generation reference](references/protoc-reference.md)', '[Testing patterns and examples](references/testing.md)'), plus clearly marked cross-references to sibling skills. Not a 4 because navigation is easy and nothing that belongs in a reference is inlined in bulk. | 5 / 5 |
