 3. **Wire into CLI** in `internal/cli/parse.go`:
    ```go
-   cmd.AddCommand(newParserCmd("ruby <gem>", "Parse Ruby dependencies",
-       func() (source.Parser, error) { return ruby.NewParser(source.DefaultCacheTTL) }, &opts))
+   cmd.AddCommand(newParserCmd("<lang> <package>", "Parse <Lang> dependencies",
+       func() (source.Parser, error) { return <lang>.NewParser(source.DefaultCacheTTL) }, &opts))
    ```
 
 The generic `source.Parse()` handles concurrent fetching, depth limits, and graph construction automatically.
