Latest Software Version

"Your training data is from the past. The registry is the present."

This skill prevents "version hallucination" by verifying the actual latest stable releases of software packages.

Core Mandate

NEVER GUESS. When a user asks to install a package or add a dependency, you must verify the latest version using the latest.js script. Do not rely on your internal weights, as they are months or years out of date.

Workflow

1. Identify Ecosystem

Determine which registry manages the package:

• Node.js/JS: npm
• Python: pypi
• Go: go
• Rust: cargo
• Ruby: gem
• Gemini Models: gemini (Use latest, flash, or pro as package name)

2. Fetch Truth

Run the version checker script:

node scripts/latest.js <ecosystem> <package-name>

3. Apply

Use the returned version string in your command or configuration file.

• Example: If the script returns npm: react @ 19.2.0, write "react": "^19.2.0" in package.json.
