Quality

Content

85%

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

This is a well-crafted, highly concise Rust style guide that respects Claude's existing knowledge and focuses on non-obvious, Rust-specific conventions. Its main strength is extreme token efficiency through table-based formatting. The primary weakness is that actionability could be improved with a few short executable code examples demonstrating the less intuitive patterns (e.g., conversion naming, newtype usage).

Suggestions

Add 1-2 brief executable code examples for the less obvious patterns like conversion naming (as_/to_/into_) or newtype usage to boost actionability.

DimensionReasoningScore

Conciseness

Extremely lean and efficient. Uses tables for maximum information density, avoids explaining concepts Claude already knows, and explicitly acknowledges Claude's existing Rust knowledge in the closing line. Every token earns its place.

3 / 3

Actionability

Provides concrete naming patterns and specific alternatives (e.g., `OnceLock` over `lazy_static!`), but lacks executable code examples. The guidance is specific but presented as terse rules rather than copy-paste ready code snippets that demonstrate the patterns in context.

2 / 3

Workflow Clarity

This is a reference/style-guide skill, not a multi-step workflow skill. For its purpose (code style lookup), the organization into clear categorical sections with table format makes finding and applying individual rules unambiguous. No destructive or batch operations are involved.

3 / 3

Progressive Disclosure

For a concise reference skill under 50 lines with no need for external references, the content is well-organized into logical sections (Naming, Data Types, Strings, Error Handling, etc.) with a quick reference summary. The structure supports easy scanning and discovery.

Description

89%

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 has strong trigger term coverage and clear 'when to use' guidance, making it effective for skill selection. Its main weakness is that it reads more like a keyword dump than a structured capability description—it lacks explicit concrete actions (the 'what it does' is implied through keywords rather than stated as actions). The inclusion of Chinese keywords is a nice touch for multilingual support.

Suggestions

Add explicit capability statements before the keywords, e.g., 'Provides guidance on Rust naming conventions, code formatting with rustfmt, linting with clippy, and code review best practices.'

DimensionReasoningScore

Specificity

The description names the domain (Rust code style/best practices) and mentions some actions implicitly (naming, formatting, linting, code review), but does not list concrete specific actions like 'enforce naming conventions', 'run clippy checks', or 'format code with rustfmt'. It reads more like a keyword list than a capability description.

2 / 3

Completeness

It explicitly answers 'when' with 'Use when asking about Rust code style or best practices' and provides the 'what' domain through the keyword list. The 'Use when...' clause is present and clear, satisfying the completeness requirement.

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms including tool names (clippy, rustfmt), common user phrases (code style, best practice, naming convention, code review), specific sub-topics (variable naming, function naming, type naming), internal codes (P.NAM, G.FMT), and even Chinese equivalents (命名规范, 代码风格, etc.).

3 / 3

Distinctiveness Conflict Risk

The description is clearly scoped to Rust-specific code style and best practices, with distinct triggers like 'clippy', 'rustfmt', 'P.NAM', 'G.FMT' that are unlikely to conflict with general coding skills or other language-specific skills.
