Discovery

85%

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

This is a strong skill description that clearly defines its specialized role in C4 architecture documentation. It effectively communicates specific actions and includes an explicit 'Use when' clause. The main weakness is that trigger terms could be expanded to include more natural variations users might use when requesting this type of work.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Synthesizes C4 Code-level documentation into Component-level architecture', 'defining component boundaries, interfaces, and relationships', 'Creates component diagrams and documentation'.

3 / 3

Completeness

Clearly answers both what ('Synthesizes C4 Code-level documentation into Component-level architecture, defining component boundaries, interfaces, and relationships. Creates component diagrams and documentation') and when ('Use when synthesizing code-level documentation into logical components').

3 / 3

Trigger Term Quality

Includes relevant terms like 'C4', 'Component-level', 'component diagrams', 'architecture', but missing common variations users might say such as 'component diagram', 'system components', 'architecture documentation', or simpler terms like 'components'.

2 / 3

Distinctiveness Conflict Risk

Very specific niche targeting C4 Component-level documentation specifically, with clear distinction from other C4 levels (Code, Container, Context) and general documentation skills. The explicit mention of 'C4 Code-level' to 'Component-level' synthesis creates a distinct trigger.

Implementation

37%

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

This skill provides useful C4 component documentation templates and Mermaid diagram syntax, but lacks a clear actionable workflow for actually synthesizing code-level documentation into components. The heavy use of placeholders reduces immediate actionability, and the absence of step-by-step synthesis instructions with validation checkpoints limits its practical utility.

Suggestions

Add a concrete step-by-step workflow for synthesizing c4-code-*.md files into components, including validation checkpoints (e.g., '1. Identify code files → 2. Group by responsibility → 3. Validate boundaries → 4. Generate component doc')

Replace at least one template section with a fully filled-in concrete example showing a real component (e.g., 'AuthenticationComponent' with actual features, interfaces, and code element links)

Remove or condense the generic 'Use this skill when' boilerplate section which adds little value with placeholder text

Add explicit validation criteria for component boundaries (e.g., 'A component should have single responsibility, 3-7 code elements, clear interface')

DimensionReasoningScore

Conciseness

The skill contains some unnecessary boilerplate (generic 'Use this skill when' sections with placeholders) and explanatory text that could be trimmed. However, the core templates and examples are reasonably efficient.

2 / 3

Actionability

Provides templates and Mermaid diagram examples which are somewhat actionable, but relies heavily on placeholders ([Component Name], [Description]) rather than concrete, filled-in examples. The instructions section is vague ('Apply relevant best practices').

2 / 3

Workflow Clarity

No clear workflow sequence for synthesizing code-level docs into components. The 'Example Interactions' list tasks but doesn't provide step-by-step process with validation checkpoints for the synthesis workflow.

1 / 3

Progressive Disclosure

References external resources (implementation-playbook.md, c4model.com) and links to code files, but the main document is somewhat monolithic with templates that could be split. Navigation structure exists but could be clearer.
