c4-component
Build C4 Component Documentation
Teams often struggle to turn code-level notes into clear C4 component architecture. This skill guides Claude, Codex, and Claude Code to group code elements into components, document interfaces, and create Mermaid diagrams.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "c4-component" from https://skillstore.io/skills/sickn33-c4-component.md and its manifest at https://skillstore.io/api/skills/sickn33-c4-component/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "c4-component". A team provides c4-code docs for authentication controllers, token services, and user repositories.
Expected outcome:
The skill returns an authentication component summary with boundaries, responsibilities, interfaces, dependencies, and relationship diagram notes.
Using "c4-component". An architect asks how payment code, database access, and API clients should be grouped.
Expected outcome:
The skill proposes payment-facing components, explains boundary choices, and marks uncertain ownership decisions for review.
Using "c4-component". A documentation owner needs a component index for one application container.
Expected outcome:
The skill produces a master index outline with component names, descriptions, document links, and relationship summaries.
Security Audit
SafeThe static alerts are false positives caused by inline Markdown backticks, fenced examples, C4 terminology, and one public documentation link. No evidence of command execution, system reconnaissance, data exfiltration, or prompt-injection intent was found in SKILL.md. The remaining concerns are documentation clarity issues, not security issues.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Prepare Architecture Docs
Turn scattered code-level notes into a consistent component document for review.
Plan Refactoring Boundaries
Group related files into components before planning ownership or modularization changes.
Maintain System Documentation
Create component indexes and relationship notes for onboarding and audits.
Try These Prompts
Use the c4-component skill to document one component from these c4-code notes. Include purpose, features, interfaces, dependencies, and diagram guidance.
Use the c4-component skill to group these c4-code files into logical components. Explain each boundary and list the files inside each component.
Use the c4-component skill to identify component interfaces, protocols, operations, dependencies, and external systems. Flag any inferred details for review.
Use the c4-component skill to create component documentation and a master index for this container. Include diagram notes and unresolved questions.
Best Practices
- Provide current c4-code files and known container boundaries before requesting synthesis.
- Ask for boundary rationale when several component groupings are possible.
- Review generated diagrams against real dependency paths before publication.
Avoid
- Using the skill without source documents or repository context.
- Mixing component diagrams with deployment, infrastructure, or system context concerns.
- Treating inferred interfaces as verified API contracts.
