What problem does it solve? New or undocumented codebases lack architecture documentation, forcing developers to reverse-engineer system structure manually. This Skill detects the repository type, deploys matching architecture templates into .claude/architecture/, and populates only the missing files by analyzing the actual source code. ## Core Features & Use Cases - Stack Detection: Identifies repo type across .NET API, ASP.NET Framework/MVC, Angular (Nx/standard), React, JS libraries, Spring Boot, Python (Django/FastAPI/Flask), and VSTO add-ins. - Deployment Context Capture: Runs a gated questionnaire covering hosting, CI/CD, secrets, Entra ID authentication, and rollback, writing architecture-deployment.md only after explicit APPROVED confirmation. - Template Population: Composes an 8-file architecture set (overview, call chains/flows, reference, data, integrations, security, decisions) with Mermaid diagrams, filling every section from source files and marking unknowns with ⚠ markers instead of guessing. - Use Case: After cloning a legacy .NET Framework + Angular solution, run the architect skill to generate a complete architecture documentation set — including per-project runtime versions, middleware pipelines, and an Entra ID auth model — without writing any docs by hand. ## Quick Start Ask the AI to populate the architecture docs for this repository by analyzing the codebase and filling in the missing architecture files.
