Anthony Gregis's Claude Code plugins.

Ships one plugin today:

Plugin	Language server	Extensions
elixir-ls	ElixirLS	.ex, .exs, .eex, .leex

Install

In Claude Code, add this repo as a marketplace and install the plugin:

/plugin marketplace add https://github.com/anthonygregis/gregis-plugins
/plugin install elixir-ls@gregis-plugins

That's it — restart Claude (or /reload-plugins) and the LSP tool will work in any Elixir project.

Prerequisite: language_server.sh (from ElixirLS) and elixir must be on your PATH in the shell you launch Claude from. See elixir-ls/README.md for install instructions.

What this gives Claude

The LSP tool exposes nine operations against your Elixir code:

• goToDefinition / goToImplementation
• findReferences
• hover
• documentSymbol / workspaceSymbol
• prepareCallHierarchy / incomingCalls / outgoingCalls

Plus real-time diagnostics for everything Claude edits.

How it works

Each plugin in this marketplace is a thin manifest. Claude Code itself implements the LSP wire protocol — JSON-RPC framing, lifecycle, request routing — and exposes it as the built-in LSP tool. The plugin just tells Claude which binary to launch for which file extensions.

Contributing

PRs welcome. Per-plugin notes live next to each plugin (e.g. elixir-ls/README.md).
