generate-tech-stack

Scan any project and generate a visual TECH_STACK.html page — light/dark theme, auto-adapting, zero config.

Works as a Claude Code skill, MCP server, or GitHub Copilot Extension.

Live demo → — generated from fastapi/full-stack-fastapi-template, unmodified.

(real CLI output, unscripted — static screenshot if you'd rather not autoplay)

What it produces

Every generated page contains:

Section	Description
Stat row	Total tools · Categories · AI Backends · Data Stores
Architecture diagram	Layered flow diagram (Consumer → API → AI/NLP → Data/Obs/Frontend)
Bar chart	Horizontal bars per category, colour-matched
Tool cards	One card per category; each tool shows a dot, name, description, and badge
Badge legend	Explains pip, dep, optional, core, deploy, ci, etc.
Footer	Project name · tool count · generation date
Guided tour	Spotlight walkthrough of every section, shown automatically the first time a report is opened; replay anytime with the ? button
Theme toggle	Sun/moon button next to the tour button switches between dark and light mode

Usage

pip (CLI + MCP server)

pip install generate-tech-stack-mcp

generate-tech-stack . TECH_STACK.html    # CLI: scan and write the report
generate-tech-stack-mcp                   # stdio MCP server

With pip installed, any MCP host config reduces to:

{
  "mcpServers": {
    "generate-tech-stack": { "command": "generate-tech-stack-mcp" }
  }
}

Claude Code

/generate-tech-stack

Run it from any project directory. The skill calls scripts/analyze.py and opens the result in your browser.

MCP (Claude Desktop, VS Code, Cursor, Zed, Windsurf, Continue)

pip install mcp

Add to your host's MCP config (replace the path with your actual home directory):

{
  "mcpServers": {
    "generate-tech-stack": {
      "command": "python3",
      "args": ["/home/<you>/.claude/skills/generate-tech-stack/mcp/server.py"]
    }
  }
}

Then ask: generate my tech stack or /generate-tech-stack.

MCP tools exposed:

• generate_tech_stack — scans a project, writes TECH_STACK.html, opens in browser
• list_tech_stack — returns a JSON summary, no file written

GitHub Copilot Extension

cd copilot
npm install
npm start        # listens on port 3000
ngrok http 3000  # expose for GitHub to reach

Register a GitHub App with Copilot Extension enabled, set the Agent URL to https://your-url/agent, and install it on your account. Then in Copilot Chat:

@generate-tech-stack /generate-tech-stack
@generate-tech-stack /generate-tech-stack /path/to/project

Command line (standalone)

python3 ~/.claude/skills/generate-tech-stack/scripts/analyze.py /path/to/project
# output: /path/to/project/TECH_STACK.html

# custom output path:
python3 scripts/analyze.py . ~/Desktop/TECH_STACK.html

analyze.py has no third-party dependencies — just Python 3.8+.

Design

Dark by default with a light-mode toggle (top-right corner, no persistence — resets to dark on reload). Fonts: IBM Plex Sans (body) + JetBrains Mono (code/badges), loaded from Google Fonts. Vanilla JS powers the guided tour and theme toggle only — everything else is plain HTML + CSS. Self-contained single file, opens in any browser offline.
