C4 Code

This generates C4 code-level documentation by analyzing directories and extracting function signatures, class hierarchies, dependencies, and data flows. You point it at a codebase and it outputs structured docs with method signatures, file locations, and dependency graphs. Works across paradigms: it'll use class diagrams for OOP code, flowcharts for functional pipelines, and module structures for procedural stuff. Honestly most useful when onboarding to unfamiliar code or documenting complex components where you need the internal structure mapped out. The template is comprehensive but might be overkill for simple utilities. Pairs well with the other C4 agents if you're doing full architecture documentation.
