Platform Detector

Detect platforms and runtimes (Oryx-style detection). Answers: "What tech stack is this?"

Detects Node.js, Python, Rust, Go, .NET, Java, Ruby, PHP with version information and confidence levels. Based on Microsoft Oryx's marker-file detection patterns.

Usage

CLI

python platform_detector.py <project_path>
python platform_detector.py <project_path> --json
python platform_detector.py <project_path> --output platforms.json

MCP

drydock_platforms(project_path: str) -> str

Returns platform detection results as JSON.

Example Output

{
  "project_path": "/path/to/my-project",
  "project_name": "my-project",
  "platforms": [
    {
      "platform": "Python",
      "version": "3.11",
      "confidence": "high",
      "marker_files": [
        "pyproject.toml",
        "requirements.txt",
        "setup.py"
      ],
      "version_source": "pyproject.toml"
    },
    {
      "platform": "Node.js",
      "version": "18.0.0",
      "confidence": "high",
      "marker_files": [
        "package.json",
        "package-lock.json"
      ],
      "version_source": "package.json"
    }
  ],
  "is_multi_platform": true

Detection Patterns

Drydock detects platforms by looking for marker files:

Python

• pyproject.toml
• setup.py
• requirements.txt
• Pipfile
• .python-version

Version detection from: pyproject.toml, setup.py, .python-version

Node.js

• package.json
• package-lock.json
• yarn.lock
• pnpm-lock.yaml
• .nvmrc or .node-version

Version detection from: .nvmrc, .node-version, package.json engines field

Rust

• Cargo.toml
• Cargo.lock
• rust-toolchain.toml
• rust-toolchain

Version detection from: rust-toolchain, Cargo.toml

Go

• go.mod
• go.sum

Version detection from: go.mod

.NET

• .csproj
• .sln
• app.config
• web.config

Version detection from: .csproj TargetFramework

Java

• pom.xml
• build.gradle
• .java-version

Version detection from: pom.xml, build.gradle

Ruby

• Gemfile
• .ruby-version

Version detection from: .ruby-version, Gemfile

PHP

• composer.json
• composer.lock

Version detection from: composer.json

Confidence Levels

• high: Multiple marker files found, version confirmed
• medium: Marker files found, version uncertain or missing
• low: Single marker file, could be false positive

Options

Flag	Type	Default	Description
project_path	positional	required	Path to project root
--json	flag	false	Output as JSON
--output, -o	string	stdout	Output file path
