What this skill does
C4 Architecture Documentation Workflow Generate comprehensive C4 architecture documentation for an existing repository/codebase using a bottom-up analysis approach. [Extended thinking: This workflow implements a complete C4 architecture documentation process following the C4 model (Context, Container, Component, Code). It uses a bottom-up approach, starting from the deepest code directories and working upward, ensuring every code element is documented before synthesizing into higher-level abstractions. The workflow coordinates four specialized C4 agents (Code, Component, Container, Context) to create a complete architectural documentation set that serves both technical and non-technical stakeholders.] Use this skill when Working on c4 architecture documentation workflow tasks or workflows Needing guidance, best practices, or checklists for c4 architecture documentation workflow Do not use this skill when The task is unrelated to c4 architecture documentation workflow You need a different domain or tool outside this scope Instructions Clarify goals, constraints, and required inputs. Apply relevant best practices and validate outcomes. Provide actionable steps and verification. If detailed examples are required, open resources/implementation-playbook.md. Overview This workflow creates comprehensive C4 architecture documentation following the official C4 model by: 1. Code Level: Analyzing every subdirectory bottom-up to create code-level documentation 2. Component Level: Synthesizing code documentation into logical components within containers 3. Container Level: Mapping components to deployment containers with API documentation (shows high-level technology choices) 4. …
