Comprehensive project architecture blueprint generator that analyzes codebases to create detailed architectural documentation.

  • Works in 12 steps: Architecture Detection and Analysis → Architectural Overview → Architecture Visualization → …

What it does

Architecture Blueprint Generator is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. 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.

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Diagrams. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Tasks that involve Diagrams

Example prompts

  • “/architecture-blueprint-generator”

Requirements

  • Python 3
  • Node.js

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Architecture Detection and Analysis
  2. Architectural Overview
  3. Architecture Visualization
  4. Core Architectural Components
  5. Architectural Layers and Dependencies
  6. Data Architecture
  7. Cross-Cutting Concerns Implementation
  8. Service Communication Patterns
  9. Technology-Specific Architectural Patterns
  10. Implementation Patterns
  11. Testing Architecture
  12. Deployment Architecture

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Architecture Blueprint Generator loads about 3.3k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 1,225 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
