# 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 Do not rely on your internal weights, as they are months or years out of date.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:
```bash
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`.

## Supported Registries
*   **NPM**: `registry.npmjs.org`
*   **PyPI**: `pypi.org`
*   **Go Proxy**: `proxy.golang.org`
*   **Crates.io**: `crates.io`
*   **RubyGems**: `rubygems.org`
