Quality

Content

53%Weight 40%Scale 1-5

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 well-organized, self-contained instruction set with a sensible six-step workflow and a defined report format, but it leans descriptive rather than executable — tools are named without invocations and checkpoints are implicit. Trimming the persona padding and adding concrete commands would lift actionability and workflow clarity.

Suggestions

Add concrete executable commands for the tools already named, e.g. a full `jscpd --min-tokens 50 <path>` and `ast-grep` invocation example, instead of 'Run duplication detection tools with appropriate parameters'.

Trim persona padding ('expertise spans multiple programming languages with deep knowledge of...') and generic bullets like 'Provide actionable recommendations, not just criticism' — Claude already knows to do these.

Make workflow checkpoints explicit, e.g. how many files to sample for naming analysis, and a verification step such as spot-checking flagged anti-patterns before reporting them.

DimensionReasoningScore

Conciseness

The persona framing ("deep knowledge of software architecture principles and best practices") and generic bullets ("Provide actionable recommendations, not just criticism") are padding Claude does not need, though the responsibility lists themselves are substantive — fitting 'mostly efficient but includes some unnecessary explanation' rather than the heavily padded level 2.

3 / 5

Actionability

There are concrete touches ("`ast-grep` for structural AST matching", "--min-tokens 50"), but most guidance stops short of executable commands — "Run duplication detection tools with appropriate parameters" names the tool without an invocation, matching 'some concrete guidance but incomplete' rather than the copy-runnable level 4.

3 / 5

Workflow Clarity

The six-step workflow is coherently sequenced, but checkpoints are only implicit and steps like "Analyze naming conventions by sampling representative files" give no sampling criteria, matching 'steps listed but validation gaps'; it is above level 2 because the sequence itself is complete and sensible.

3 / 5

Progressive Disclosure

The skill is self-contained with no bundle files and no buried references, organized into clear responsibilities, workflow, report-format, and guidelines sections — good structure with only minor organization gaps (the inline examples block and ~65-line body keep it below the lean level-5 case).

Description

88%Weight 40%Scale 1-5

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

A strong description: it states four concrete capabilities in third person and includes an explicit, specific 'Use when...' clause with two natural trigger conditions. Its only weaknesses are missing common synonyms (e.g., 'code smells', 'code quality') and minor overlap risk with general code-review skills.

DimensionReasoningScore

Specificity

"Analyzes code for design patterns, anti-patterns, naming conventions, and duplication" lists four distinct concrete analysis actions with comprehensive coverage, matching the level-5 anchor; the level-4 anchor would imply only partial coverage with gaps.

5 / 5

Completeness

It explicitly answers what ("Analyzes code for design patterns, anti-patterns, naming conventions, and duplication") and when with two concrete trigger phrases ("Use when checking codebase consistency or verifying new code follows established patterns"), matching the level-5 anchor exactly rather than the level-4 'when could be more specific' case.

5 / 5

Trigger Term Quality

"codebase consistency", "established patterns", and "duplication" are natural user phrasings, but common synonyms like "code smells", "code quality", or "best practices" are absent, fitting the level-4 anchor rather than full synonym-level coverage.

4 / 5

Distinctiveness Conflict Risk

The pattern-analysis niche ("design patterns, anti-patterns, naming conventions, and duplication") is clearly distinguishable, but it overlaps with general code-review and code-quality skills, fitting 'mostly distinct; minor overlap risk' rather than minimal conflict risk.
