BGforge Claude Code Plugins

Claude Code plugin marketplace for Infinity Engine and classic Fallout modding languages.

bgforge-mls-lsp

Code intelligence for Fallout SSL, WeiDU (BAF/D/TP2), and related modding languages. Provides completion, hover, go-to-definition, diagnostics, formatting, symbols, rename, and inlay hints.

Supported languages:

Language	Extensions
Fallout SSL	.ssl, .h
WeiDU BAF	.baf, .slb
WeiDU D	.d
WeiDU TP2	.tp2, .tpa, .tph, .tpp

Not all features are available for all languages. BAF has the smallest feature set (completion, hover, formatting, inlay hints). SSL and D have the richest.

The plugin includes a skill that teaches Claude to use LSP tools proactively when working with these file types.

Installation

1. Install the language server:

   npm install -g @bgforge/mls-server

2. Add the marketplace:

   /plugin marketplace add BGforgeNet/claude-bgforge-tools
   

3. Install the plugin:

   /plugin install bgforge-mls-lsp@bgforge-tools
   

4. Exit and relaunch claude (LSP servers require a restart).

To verify, ask Claude about a symbol in a .ssl, .baf, .d, or .tp2 file. If it uses LSP tools (hover, go-to-definition) instead of grepping, the plugin is working.

Troubleshooting

• "Executable not found in $PATH" - install the server: npm install -g @bgforge/mls-server
• "No LSP server available" - restart Claude Code after installing the plugin
• Server not starting - verify with bgforge-mls-server --stdio (should hang waiting for input; Ctrl+C to exit)
