Quality

Content

50%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body delivers concrete, executable Rust guidance and a useful regeneration-safety table, but it is undercut by a stubbed SDK-clients section, some redundancy between the example and Key Patterns, and missing build-time validation steps. It is solidly competent but not fully complete.

Suggestions

Replace the empty "Available SDK Clients" section with the actual sub-client list (or a pointer to a generated reference) so the guidance is complete.

Remove the Key Patterns duplication of client()/block_on() or fold it into the main example to tighten token use.

Add a validation checkpoint in Build & Test, e.g. run `cargo build` then `cargo test` and how to diagnose common compile errors against a changed SDK surface.

DimensionReasoningScore

Conciseness

The body is mostly lean, but the "Key Patterns" section re-demonstrates client() and block_on() already shown in the step-1 code example, and the parenthetical about sub-clients adds little, so it could be tightened.

2 / 3

Actionability

The register() example and build commands are concrete and executable, but the "Available SDK Clients" section is a stub ("Sub-clients are derived from the API spec at generation time") with no actual client listing, leaving a key detail incomplete.

2 / 3

Workflow Clarity

Steps are sequenced (edit custom.rs → use SDK clients → key patterns → regenerate → build), but there are no validation checkpoints or error-recovery guidance for the build/test phase.

2 / 3

Progressive Disclosure

Content is well-sectioned but monolithic in a single file with no one-level-deep references; with no bundle files present everything is inline rather than split into navigable references.

Description

57%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description identifies a clear, specific niche but tells only half the story — it says what the skill does without saying when to invoke it. Adding an explicit "Use when..." clause and more natural trigger terms would lift the weaker dimensions.

Suggestions

Add an explicit trigger clause, e.g. "Use when extending the server-url-templating-api-single-base-url CLI with user-authored commands or wiring into its SDK."

Include natural user-facing keywords (e.g. "custom CLI commands", "SDK client", "add a command") alongside the technical identifier.

Optionally enumerate concrete actions (register a command, call SDK methods, preserve code across regeneration) to reach specificity 3.

DimensionReasoningScore

Specificity

The phrase "author custom commands for the ... CLI using the co-generated SDK" names a concrete domain and a single action, but lists only one action rather than multiple specific concrete actions, so it stops short of a 3.

2 / 3

Completeness

It states what the skill does ("author custom commands") but provides no "Use when..." trigger guidance, which caps completeness at 2 per the rubric guidelines.

2 / 3

Trigger Term Quality

Natural-ish terms like "custom commands" and "CLI" appear, but the highly technical identifier "server-url-templating-api-single-base-url" and "co-generated SDK" are jargon, missing common user-facing variations.

2 / 3

Distinctiveness Conflict Risk

The extremely specific CLI identifier "server-url-templating-api-single-base-url" carves a clear niche, making it unlikely to trigger for the wrong skill.
