architecture-blueprint-generator (github/awesome-copilot): a skill that writes a full architecture document for your codebase

This skill makes Claude read your codebase and write a Project_Architecture_Blueprint.md with its layers, components, data flow, patterns and diagrams.

Ask Claude to document the architecture of a project and this skill sends it through a long checklist. It detects the tech stack and architecture pattern from your files, then writes a blueprint covering components, layers, data, cross-cutting concerns, service communication, testing, deployment and how to extend the system.

SKILL.md sets eight options for the run: project type, architecture pattern, diagram type (C4, UML, flow, component or none), detail level, code examples, implementation patterns, decision records and extensibility focus. The skill bundles no scripts, and the result is one Markdown file.

Good for

Engineers who join a codebase and need a map of how it fits together
Tech leads who want an architecture reference for new contributors
Teams that want a baseline document before they refactor

What's in the skill

When it loads

Comprehensive project architecture blueprint generator that analyzes codebases to create detailed architectural documentation. Automatically detects technology stacks and architectural patterns, generates visual diagrams, documents implementation patterns, and provides extensible blueprints for maintaining architectural consistency and guiding new development.

3. Components and layers
Domain model, data access, mapping, caching and validation.
4. Data architecture
Security, errors, logging, validation and configuration.
5. Cross-cutting concerns
Boundaries, protocols, sync versus async, versioning and discovery.
6. Service communication
Patterns for .NET, Java, React, Angular and Python.
7. Stack-specific patterns

Questions

What does the skill do?

It makes Claude analyze a codebase and write one architecture document, Project_Architecture_Blueprint.md. The document covers technology stack, patterns, components, layers, data, cross-cutting concerns, communication, testing, deployment, extension points and a guide for new development.

How do I install it?

Use the install box above. The skill is a single SKILL.md file from GitHub's awesome-copilot collection, so a folder copy or the skills CLI command is enough.

What can I configure?

Eight settings: project type, architecture pattern, diagram type, detail level, and four on or off switches for code examples, implementation patterns, decision records and extensibility focus. Most default to auto-detect.

Which stacks does it know?

The project type options are .NET, Java, React, Angular, Python, Node.js, Flutter, other or auto-detect. SKILL.md has stack-specific sections for .NET, Java, React, Angular and Python.

Which diagrams can it make?

C4, UML, flow or component diagrams, or none. SKILL.md says diagrams must reflect the actual implementation, not a theoretical pattern, and without diagrams it writes text descriptions.

Does it need an API key?

No key is mentioned. The skill bundles no scripts.

Is it safe?

Claude reads project files to build the blueprint, so the code it reads is visible to your AI tool. The output is a new Markdown file. The awesome-copilot README says its customizations come from third-party developers, so read a skill before you install it.

Is it only for GitHub Copilot?

It lives in the github/awesome-copilot collection, which is built for GitHub Copilot. The skill itself is a plain SKILL.md, so it installs with the skills CLI like other skills.
