c4-container
tessl i github:sickn33/antigravity-awesome-skills --skill c4-containerExpert 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.

Implementation
38%This skill provides useful templates for C4 Container documentation but lacks a clear actionable workflow for actually performing the synthesis task. It describes the output format well but doesn't guide Claude through the process of analyzing components and mapping them to containers. The templates are placeholder-heavy rather than providing concrete executable examples.
Suggestions
- Add a numbered workflow sequence: 1) Identify deployment boundaries, 2) Group components by deployment unit, 3) Document container interfaces, 4) Validate mappings against infrastructure configs, 5) Generate diagrams
- Replace placeholder templates with one concrete, realistic example showing a complete container documentation (e.g., a real 'User Service' container with actual endpoints)
- Add validation checkpoints such as 'Verify each component is assigned to exactly one container' and 'Confirm API specs match actual implementation'
- Move the OpenAPI template to a separate reference file and keep only a brief example in the main skill
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill contains useful templates but includes some unnecessary explanation (e.g., 'Use this skill when/Do not use this skill when' sections are generic). The templates themselves are reasonably efficient but could be tightened. | 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 contain [bracketed placeholders] rather than concrete, copy-paste-ready examples with realistic data. | 2 / 3 |
Workflow Clarity | No clear workflow sequence for synthesizing components into containers. The skill describes what to document but not how to perform the synthesis process step-by-step. Missing validation checkpoints for verifying container mappings are correct. | 1 / 3 |
Progressive Disclosure | References external resources like 'resources/implementation-playbook.md' and component documentation links, but the main content is somewhat monolithic. The structure exists but API specification template could be in a separate file given its length. | 2 / 3 |

Activation
77%This is a well-structured description that clearly articulates specific capabilities and includes an explicit 'Use when' clause. The main weakness is the heavy reliance on technical C4 terminology that users may not naturally use when requesting help, and potential overlap with other architecture documentation skills.
Suggestions
- Add more natural trigger terms users might say, such as 'architecture diagrams', 'deployment docs', 'system containers', or 'how services connect'
- Clarify distinction from other C4-level skills (Component, Context) by emphasizing the specific deployment/container focus more prominently in trigger terms
| 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 documentation, 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 some relevant terms like 'C4', 'Container-level', 'deployment containers', 'container diagrams', but uses technical jargon that users may not naturally say. Missing common variations like 'architecture docs', 'system diagrams', or 'deployment documentation'. | 2 / 3 |
Distinctiveness Conflict Risk | The C4 Container-level focus provides some distinction, but could overlap with other architecture documentation skills or general C4 skills. The term 'deployment' and 'architecture' are fairly common across documentation tools. | 2 / 3 |
