How to use the Architecture Blueprint Generator agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The architecture-blueprint-generator is an agent skill, a set of instructions that an AI agent reads and follows when you ask it for help. When installed, it tells the agent how to examine a software project's files, dependencies and folder layout, then write a Project_Architecture_Blueprint.md document describing how the code is built. This guide explains what the skill does, how to install it, how to trigger it, and what to check in the output before you rely on it.
Architecture Blueprint Generatorgithub/awesome-copilot · MIT Download the skill Quick start
- 1Download the ZIP. Download the architecture-blueprint-generator skill as a ZIP from this page.
- 2Unzip into a skills folder. Extract it into ~/.claude/skills/ for all projects, or into the project's .claude/skills/ folder for one project.
- 3Or upload it in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the ZIP.
- 4Open the project. Open the codebase you want to document and confirm the agent can read its files.
- 5Ask for a blueprint. Request an architecture blueprint in plain language, optionally naming a diagram type and detail level.
- 6Review the output. Check the generated Project_Architecture_Blueprint.md against the real code and correct anything wrong.
What the skill makes the agent do
The skill's job is to have the agent analyze a codebase rather than a written description of one. It directs the agent to look at project and configuration files, package dependencies and import statements, framework conventions, build and deployment configuration, and folder organization.
The document it asks for covers the technology stack, architectural patterns, layers and dependency rules, core components, data architecture, cross-cutting concerns such as authentication, error handling, logging and configuration, and how services communicate. It also asks the agent to note circular dependencies or layer violations it finds.
- Detects technology stacks and architectural patterns, or uses ones you specify
- Can produce C4, UML, flow or component diagrams, or text-only descriptions if you choose None
- Documents implementation patterns and extension points for new development
- Can be set to a high-level, detailed, comprehensive or implementation-ready level of detail
Install the architecture-blueprint-generator skill
Download the skill as a ZIP file from this page. The skill is a single file, SKILL.md, and it contains no code to install. You have two ways to add it to your agent.
For Claude Code, unzip the download into ~/.claude/skills/ to make it available across your projects, or into a project's .claude/skills/ folder to make it available only in that project. In the Claude apps, open Settings, go to Capabilities, and upload the skill under Skills.
- Personal install: unzip into ~/.claude/skills/
- Project install: unzip into the project's .claude/skills/ folder
- Claude apps: Settings → Capabilities → Skills, then upload the ZIP
Trigger the skill with a natural request
You do not need special syntax. Open the project you want documented, make sure the agent can read its files, and ask in plain language for an architecture blueprint or architectural documentation of the codebase. The skill's instructions tell the agent to produce a file named Project_Architecture_Blueprint.md.
Be specific about what you need. Saying which diagram style you want, such as C4 or UML, and how detailed the document should be, helps the agent match the output to your purpose.
- Example: 'Analyze this project and write an architecture blueprint as Project_Architecture_Blueprint.md.'
- Example: 'Create a C4 diagram set and a high-level blueprint of this codebase.'
- Example: 'Document the layers and dependency rules, and note any layer violations.'
Configure the output
The skill file defines configuration variables near the top of SKILL.md. They control the primary technology, the architectural pattern (or Auto-detect), the diagram type (C4, UML, Flow, Component or None), and the detail level (High-level, Detailed, Comprehensive or Implementation-Ready).
Several true/false settings control whether the document includes sample code to illustrate patterns, detailed implementation patterns, architectural decision records, and an emphasis on extension points. Leave the defaults as Auto-detect if you are not sure what the project uses.
- PROJECT_TYPE: Auto-detect, .NET, Java, React, Angular, Python, Node.js, Flutter or Other
- ARCHITECTURE_PATTERN: Auto-detect, Clean Architecture, Microservices, Layered, MVVM, MVC, Hexagonal, Event-Driven, Serverless, Monolithic or Other
- DIAGRAM_TYPE: C4, UML, Flow, Component or None
- DETAIL_LEVEL: High-level, Detailed, Comprehensive or Implementation-Ready
Check the output before you rely on it
The blueprint is generated from the agent's reading of the code, so it can be incomplete or wrong. Treat it as a draft. Compare the diagrams and layer descriptions against the actual folders and imports, and have an experienced team member review anything used for onboarding or architectural decisions.
Because the output describes what the agent found, it is most useful as a starting point for understanding a system you did not write.
- Spot-check every layer and dependency claim against the real imports
- Confirm the security, logging and data access descriptions with the team that owns the code
- Note any gaps the agent reports, since missing parts are often the least visible
Safety notes: scripts and network
The skill runs no scripts and uses no network connection, according to its description. It is a set of written instructions. The agent does need the ability to read the project files, which means anything in the folders it can access may be read as part of the analysis.
Before you point an agent at a codebase that contains secrets or confidential material, check what the agent is permitted to read in your setup, and review the generated document before sharing it, since it may describe configuration and security details.
- Runs scripts: no
- Uses network: no
- Requires an AI agent that can read the project files
What people use it for
- Taking over an unfamiliar codebase and getting a structured overview of its layers and components
- Generating written architecture documentation for a team from the actual code
- Preparing onboarding material for new developers
- Checking a codebase for layer violations and circular dependencies as a starting point for review
- Documenting extension points so new features follow the existing design
Frequently asked questions
Is the architecture blueprint generator skill free?
The skill is published under the MIT licence, which permits use, modification and redistribution under its terms. Check the licence file in the repository for the full text. The agent you run it with may have its own costs.
What do I need to use the architecture-blueprint-generator skill?
You need an AI agent that can read your project files. The skill itself contains no code to install, and it does not run scripts or use the network.
How do I install the architecture-blueprint-generator skill?
Download the ZIP from this page and unzip it into ~/.claude/skills/ for all projects, or into a project's .claude/skills/ folder. In the Claude apps, upload it under Settings → Capabilities → Skills.
Can the skill generate diagrams?
Yes. The skill's configuration can set the diagram type to C4, UML, Flow or Component, or to None for text-only descriptions. Diagrams are generated from the agent's reading of the code, so verify them.
Is the generated blueprint accurate?
Not guaranteed. The output comes from the agent's reading of the code and may be incomplete or wrong. It should be checked by a person, especially before it is used for onboarding or architecture decisions.
How is this different from manually writing architecture docs?
The skill drafts documentation from the actual code quickly, which saves time on a first version. Manual documentation involves human judgment about intent and history that the agent can only infer from the files.

Our verdict
This skill suits developers taking over an unfamiliar codebase, teams that want written architecture documentation based on the real code, and architects preparing onboarding material. It is a poor fit if the agent cannot read the project, or if you need a verified, audited architecture review, since the output must be checked by a person.
