72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a tight, well-organized, mostly actionable guide with executable Rust and a useful regeneration-safety table. Its weaknesses are the placeholder SDK-clients stub and the absence of an explicit validate-then-proceed checkpoint in the build/regenerate workflow.
Suggestions
Replace the placeholder "Available SDK Clients" stub with a concrete list of actual sub-clients and representative method signatures (or a pointer to where they are generated), so the guidance is complete rather than deferred.
Add an explicit validation/feedback step in the workflow, e.g. "After editing custom.rs, run `cargo build` and resolve any errors before invoking the command; after `fern generate`, diff the SDK surface and update custom.rs to match."
Remove the minor file-list redundancy between the Architecture block and the Regeneration Safety table by referencing one from the other, or fold the regeneration notes directly into the Architecture listing.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence — it jumps straight into file layout, executable Rust, and a regeneration-safety table without explaining what a CLI, Rust, or an SDK is. The only mild redundancy (Architecture file list vs. the Regeneration Safety table) presents the same files from two distinct angles, so every section earns its place. | 3 / 3 |
Actionability | The register()/client()/block_on() snippets and `cargo build`/`RUST_LOG=debug` commands are concrete and copy-paste ready, but the "Available SDK Clients" section is a placeholder stub — "(Sub-clients are derived from the API spec at generation time.)" — giving no actual sub-client or method names, which is the level-2 anchor of incomplete concrete guidance. | 2 / 3 |
Workflow Clarity | Steps are numbered and sequenced (edit custom.rs → register → build → run) and regeneration safety is discussed, but there is no explicit validation checkpoint or fix-and-retry feedback loop for the risky build/regenerate operations, which per the guidelines caps workflow clarity at 2. | 2 / 3 |
Progressive Disclosure | The skill is a single-purpose, self-contained overview organized into clearly labeled sections (Overview, Architecture, Adding a Custom Command, Regeneration Safety, Build & Test) with no nested or deep references and no bundle files to navigate, so the well-organized structure satisfies the level-3 anchor. | 3 / 3 |
