Quality

Content

87%

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

The body is concise, highly actionable, and well-structured with executable code and a clear file map. Its main gap is the absence of explicit validation/error-recovery checkpoints in the build-and-test workflow.

Suggestions

Add an explicit validation step after 'cargo build' (e.g., 'If the build fails, check that custom.rs method names still match the regenerated SDK surface') to create a feedback loop.

Include a brief 'verify your command works' checkpoint with an expected output example between building and running.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence (no preamble on what a CLI or Rust is); code, tables, and the file map each earn their place with minimal padding.

3 / 3

Actionability

Provides a complete, copy-paste-ready register() Rust example plus concrete bash commands ('cargo build', 'multi-url-environment-reference list-items') and an exact SDK client type table.

3 / 3

Workflow Clarity

Steps are clearly sequenced (edit custom.rs -> use SDK clients -> patterns -> auth -> build and test), but there is no explicit validation checkpoint or error-recovery feedback loop, so it sits at anchor 2 rather than 3.

2 / 3

Progressive Disclosure

Content is well-organized into clearly headed sections (Overview, Architecture, numbered steps, Regeneration Safety, Build & Test) with easy navigation and nothing that needs to be split out; no bundle files are required.

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 clearly identifies the skill's domain and distinguishes it via a specific project name, but lacks explicit 'when to use' trigger guidance and natural-language trigger terms. It would benefit from a 'Use when...' clause.

Suggestions

Add an explicit 'Use when...' clause (e.g., 'Use when extending the multi-url-environment-reference CLI with custom commands').

List a couple more concrete actions (e.g., 'register, build, and test custom commands') to lift specificity from 2 to 3.

Include natural-language trigger terms users would say rather than only the project name and 'co-generated SDK' jargon.

DimensionReasoningScore

Specificity

Names the domain and a concrete action ('author custom commands for the multi-url-environment-reference CLI using the co-generated SDK') but does not enumerate multiple specific actions, so it stops at anchor 2.

2 / 3

Completeness

It clearly states what the skill does but provides no 'Use when...' trigger guidance, which caps completeness at 2 per the rubric guidelines.

2 / 3

Trigger Term Quality

Terms like 'custom commands' and 'CLI' are relevant, but the project name 'multi-url-environment-reference' and 'co-generated SDK' are technical and miss the common natural-language variations a user would actually say.

2 / 3

Distinctiveness Conflict Risk

The highly specific project name 'multi-url-environment-reference CLI' carves out a clear niche, making it unlikely to trigger for the wrong skill.
