Ecosystem Detection

Identify the ecosystem from project files:

• package.json → npm
• requirements.txt, pyproject.toml → pypi
• go.mod → go
• Cargo.toml → cargo
• pom.xml, build.gradle → maven
• *.csproj → nuget
• Gemfile → rubygems

Rules

• Use --format json for structured output when needed
• The script handles URL encoding automatically
• Use --all-versions to see recent version history
