Expert C4 Component-level documentation specialist. Synthesizes C4 Code-level documentation into Component-level architecture, defining component boundaries, interfaces, and relationships. Creates component diagrams and documentation. Use when synthesizing code-level documentation into logical components.
Write, edit, or review chapters of an arc42 architecture documentation. Use when user says 'write arc42', 'update the architecture documentation', 'fill out chapter 5', 'arc42 chapter', 'architecture docs', or 'document our building blocks'. Do NOT use for ADRs (use document-decision — ADRs belong inside arc42 chapter 9) or user-facing feature docs (use document-feature).
Research a codebase and create architectural documentation describing how features or systems work. Use when the user asks to: (1) Document how a feature works, (2) Create an architecture overview, (3) Explain code structure for onboarding or knowledge transfer, (4) Research and describe a system's design. Produces markdown documents with Mermaid diagrams and stable code references suitable for humans and AI agents.
C3 architecture toolkit. Manages architecture docs in .c3/ directory. Operations: onboard, query, audit, change, ref, sweep. Triggers: /c3, architecture questions when .c3/ exists, C3 docs management. Classifies intent from request, loads operation-specific reference, executes. <example> user: "adopt C3 for this project" assistant: "Using c3 to onboard this project." </example> <example> user: "where is auth in the C3 docs?" assistant: "Using c3 to query the architecture." </example> <example> user: "add a new API component" assistant: "Using c3 to orchestrate the change." </example>
When the user wants to create or update a README.md file for a project. Also use when the user says "write readme," "create readme," "document this project," "project documentation," or asks for help with README.md. This skill creates absurdly thorough documentation covering local setup, architecture, and deployment.
One-stop skill for the project architecture center — draft new architecture documents, refresh existing ones, or conduct an architecture health check. Automatically determine the mode based on user input: `new` (draft)/ `update` (refresh to latest code status)/ `check` (review without modification, generate issue list). The `check` mode has three sub-objectives: consistency within a single feature design, alignment between design and code, and consistency among multiple documents under `codestable/architecture/`. Single-target rule — only modify one document or check one target at a time. Trigger scenarios: User says "fill in an architecture doc", "draft an architecture document", "refresh the architecture directory", "write down this module structure", "conduct an architecture check", "is the design internally consistent?", "does the plan match the code?", "are there conflicts among several documents in the architecture folder?", or when an architecture action is required before proceeding during the feature-design / feature-acceptance / implement phases.
Creates an Architecture Decision Record following the Nygard format to document significant technical decisions, their context, and consequences. Use when making technical choices that affect system architecture, technology selection, or development patterns.
C4 model architecture visualization and documentation
Generate an ARCHITECTURE.md file for a codebase following matklad's principles. Use when asked to "write an architecture doc", "create ARCHITECTURE.md", "document the architecture", "explain the codebase structure", "write a codemap", or when onboarding contributors to a project. Based on https://matklad.github.io/2021/02/06/ARCHITECTURE.md.html and modeled after rust-analyzer's architecture doc.
Apply or draft TOGAF-aligned enterprise architecture artifacts using ADM phases, four architecture domains, baseline-to-target analysis, governance, and migration planning.
Create well-structured RFCs and technical proposals for software projects. Use this skill whenever the user wants to write an RFC, technical proposal, design doc, architecture doc, or system design overview. Also trigger when the user says things like "write an RFC", "I need to propose a new system", "create a technical proposal", "document the architecture", "write up the design", "I need a design doc", or "explain the system architecture in a doc". Even if they just say "RFC", "design doc", or "arch doc", use this skill. Covers both RFCs (proposing what to build) and architecture docs (documenting an existing codebase).
Create a comprehensive inventory of a codebase. Map structure, entry points, services, infrastructure, domain models, and data flows. Pure documentation—no opinions or recommendations. Use when onboarding to an unfamiliar codebase, documenting existing architecture before changes, preparing for architecture reviews or migration planning, or creating a reference for the team. Triggers on requests like "map this codebase", "document the architecture", "create an inventory", or "what does this codebase contain".
