c4-container

Expert C4 Container-level documentation specialist. Synthesizes Component-level documentation into Container-level architecture, mapping components to deployment units, documenting container interfaces as APIs, and creating container diagrams. Use when synthesizing components into deployment containers and documenting system deployment architecture.

Quality

Content

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 templates for C4 Container documentation but lacks actionable workflow guidance. It tells Claude what the output should look like without explaining how to synthesize components into containers. The templates are helpful but placeholder-heavy, and there's no validation process for ensuring documentation accuracy.

Suggestions

Add a concrete step-by-step workflow for synthesizing components into containers (e.g., '1. Identify deployment boundaries from K8s manifests, 2. Group components by container, 3. Document interfaces...')

Include validation checkpoints such as 'Verify all components are mapped to exactly one container' or 'Confirm API specs match actual endpoints'

Replace placeholder templates with at least one fully worked example showing a real component-to-container synthesis

Remove generic 'Use this skill when' boilerplate that doesn't add value for Claude

Dimension	Reasoning	Score
Conciseness	The skill contains useful templates but includes some unnecessary explanation (e.g., 'Use this skill when' sections that are generic). The templates themselves are reasonably efficient but could be tighter.	2 / 3
Actionability	Provides templates and examples but they are placeholder-heavy rather than executable. The Mermaid diagram and OpenAPI spec are good starting points but require significant customization. Missing concrete step-by-step instructions for actually synthesizing components into containers.	2 / 3
Workflow Clarity	No clear workflow sequence for the synthesis process. The skill describes what outputs should look like but doesn't explain how to get there. Missing validation steps for verifying container documentation accuracy or completeness.	1 / 3
Progressive Disclosure	References 'resources/implementation-playbook.md' for detailed examples, which is good. However, the main content is somewhat monolithic with templates that could be split into separate reference files. The structure is present but not optimally organized.	2 / 3

Description

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 well-structured skill description with strong specificity and completeness, clearly defining both capabilities and usage triggers. The main weakness is the heavy reliance on technical C4 modeling jargon, which may not match how users naturally request this type of work. Users might say 'document my system architecture' rather than 'synthesize components into deployment containers'.

Suggestions

Add natural language trigger terms users might actually say, such as 'architecture documentation', 'system design docs', 'deployment diagrams', or 'how services connect'

Include file type or artifact mentions if applicable (e.g., 'PlantUML', 'Mermaid diagrams', '.puml files') to improve trigger matching

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'Synthesizes Component-level documentation into Container-level architecture', 'mapping components to deployment units', 'documenting container interfaces as APIs', and 'creating container diagrams'.	3 / 3
Completeness	Clearly answers both what (synthesizes component docs into container architecture, maps components, documents interfaces, creates diagrams) and when ('Use when synthesizing components into deployment containers and documenting system deployment architecture').	3 / 3
Trigger Term Quality	Includes domain-specific terms like 'C4', 'Container-level', 'Component-level', 'deployment units', 'APIs', and 'container diagrams', but these are technical jargon. Missing natural user phrases like 'architecture docs', 'system design', or 'deployment documentation'.	2 / 3
Distinctiveness Conflict Risk	Very specific niche targeting C4 Container-level documentation specifically, with clear distinction from Component-level or Context-level C4 work. The explicit C4 model reference and Container-level focus make it unlikely to conflict with other documentation skills.	3 / 3
