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.

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 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 |

Implementation
22%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is essentially a template shell with no substantive content about C4 Container-level documentation. It lacks any concrete guidance on mapping components to deployment units, documenting container interfaces, or creating container diagrams. The instructions are generic platitudes that could apply to any skill.
Suggestions
Add concrete examples of Container-level documentation output, including a sample container diagram in Mermaid/PlantUML and example API interface documentation
Define a specific workflow: 1) Identify deployment units from components, 2) Map component boundaries to containers, 3) Document inter-container APIs, 4) Generate container diagram
Replace generic instructions with C4-specific guidance: what makes a good container boundary, how to document container responsibilities, required metadata for container interfaces
Either populate the sub-skill links with real content or remove placeholder references that don't exist
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is relatively brief but includes generic boilerplate ('Clarify goals, constraints, and required inputs') that doesn't add value. The 'Use this skill when' and 'Do not use this skill when' sections are tautological and waste tokens. | 2 / 3 |
Actionability | The skill provides no concrete guidance on C4 Container-level documentation. Instructions are entirely abstract ('Apply relevant best practices', 'Provide actionable steps') with no executable examples, specific commands, or actual documentation patterns. | 1 / 3 |
Workflow Clarity | No clear workflow is defined for synthesizing Component-level docs into Container-level architecture. The instructions are vague directives without sequencing, validation steps, or any process for creating container diagrams or mapping components. | 1 / 3 |
Progressive Disclosure | References to sub-skills and implementation-playbook.md suggest structure, but the links appear to be placeholders (generic names like 'container-name.md'). The main content provides no useful overview before pointing elsewhere. | 2 / 3 |
Total | 6 / 12 Passed |
