Please add a metals-lsp plugin to the official claude-plugins-official marketplace, following the same pattern as kotlin-lsp, jdtls-lsp, etc.

Root Cause

Please add a metals-lsp plugin to the official claude-plugins-official marketplace, following the same pattern as kotlin-lsp, jdtls-lsp, etc.

Code Example

{
  "name": "metals-lsp",
  "description": "Scala language server (Metals) for code intelligence and refactoring",
  "version": "1.0.0",
  "lspServers": {
    "metals": {
      "command": "metals",
      "extensionToLanguage": {
        ".scala": "scala",
        ".sbt": "sbt",
        ".sc": "scala"
      },
      "startupTimeout": 120000
    }

Summary

Please add a metals-lsp plugin to the official claude-plugins-official marketplace, following the same pattern as kotlin-lsp, jdtls-lsp, etc.

Plugin config (proven working locally)

{
  "name": "metals-lsp",
  "description": "Scala language server (Metals) for code intelligence and refactoring",
  "version": "1.0.0",
  "lspServers": {
    "metals": {
      "command": "metals",
      "extensionToLanguage": {
        ".scala": "scala",
        ".sbt": "sbt",
        ".sc": "scala"
      },
      "startupTimeout": 120000
    }
  }
}

Prerequisites

  • Metals must be installed and on PATH (https://scalameta.org/metals)
  • Metals speaks standard LSP over stdio by default (no --stdio flag needed)
  • Tested with Metals 0.11.2 on macOS

File types

  • .scala — Scala source files
  • .sbt — sbt build files
  • .sc — Scala scripts / Ammonite

Community plugin process

If there is a community plugin submission process separate from the official marketplace, please document it — the current docs don't mention one. Happy to contribute this upstream if there's a path to do so.

extent analysis

TL;DR

Add the metals-lsp plugin configuration to the claude-plugins-official marketplace by following the existing pattern used for other language server plugins like kotlin-lsp and jdtls-lsp.

Guidance

  • Review the plugin configuration provided in the issue to ensure it matches the requirements for the claude-plugins-official marketplace.
  • Verify that the Metals language server is installed and available on the PATH, as it is a prerequisite for the metals-lsp plugin.
  • Check the documentation for the claude-plugins-official marketplace to see if there is a separate process for submitting community plugins, as this may be an alternative path for adding the metals-lsp plugin.
  • Test the metals-lsp plugin with different file types (.scala, .sbt, .sc) to ensure it works as expected.

Example

No code snippet is provided as the issue already includes a working plugin configuration example.

Notes

The solution assumes that the claude-plugins-official marketplace follows a similar pattern for adding new plugins as it does for existing plugins like kotlin-lsp and jdtls-lsp. If this is not the case, additional guidance may be needed.

Recommendation

Apply workaround: Document and follow any existing community plugin submission process for the claude-plugins-official marketplace, or contribute the metals-lsp plugin configuration upstream if a separate process is available. This approach allows for the addition of the metals-lsp plugin while following established procedures.
