C4 Code Level: [Directory Name]
Generate C4 Code Documentation
Codebases lack consistent, structured documentation at the code level. This skill creates comprehensive C4 code-level documentation with function signatures, class hierarchies, and visual diagrams.

Test it
Using "C4 Code Level: [Directory Name]". Analyze the src/api directory and create C4 Code-level documentation
Expected outcome:
Complete documentation including function signatures with parameters and return types, class definitions with methods, dependency lists, and a Mermaid class diagram showing the API layer structure.
Using "C4 Code Level: [Directory Name]". Create a data pipeline diagram for the ETL transformers
Expected outcome:
Mermaid flowchart showing the data transformation pipeline from raw input through validation, transformation, normalization, and aggregation stages to final output.
Security Audit
SafeThis is a prompt-only documentation skill with no executable code, network access, or external dependencies. Static analysis found zero security issues. The skill provides templates and guidance for creating C4 code-level documentation using Mermaid diagrams.

What You Can Build
Document New Code Modules
When adding new features to a codebase, generate C4 code documentation to maintain consistent documentation standards for the new modules.
Onboard New Team Members
Create comprehensive code documentation for unfamiliar parts of the codebase to help new developers understand the structure quickly.
Prepare Code for Handoff
Generate complete code documentation before transferring ownership of modules between teams or contractors.
Try These Prompts
Analyze the src/auth directory and create C4 code-level documentation showing all functions, their signatures, and dependencies.
Document the service layer code with complete class hierarchies, interface implementations, and a Mermaid class diagram.
Analyze the ETL pipeline in src/pipeline and create a data flow diagram showing all transformation functions and their composition.
Document the entire handlers package including all structs, methods, function dependencies, and create both a module structure diagram and a function dependency graph.
Best Practices
- Always include complete function signatures with all parameter types and return types
- Use consistent naming conventions across all documentation elements
- Include actual file paths and line numbers for code references
Avoid
- Creating documentation without reviewing actual source code
- Using overly complex diagrams for simple code structures
- Omitting dependency information that developers need to understand the code
