Gmod Agent Plugins — Development skill for Claude Code

gmod-agent-plugins

A cross-agent plugin marketplace for Garry's Mod GLua development. Plugin packages are structured so both Claude Code and Codex can consume the useful parts.

Marketplace files

• .claude-plugin/marketplace.json is the Claude Code marketplace. It includes the lspServers declaration that launches each project's pinned .tools/bin/glua_ls.exe.
• .agents/plugins/marketplace.json is the Codex marketplace. Codex consumes the bundled skills via each plugin's .codex-plugin/plugin.json.

Codex does not consume Claude's `lspServers` field, so this plugin is skills-only in Codex for now. Native Codex CLI LSP support is tracked in [openai/codex#8745](https://github.com/openai/codex/issues/8745).

Plugins

Plugin	Description	Required binary
`glua-lsp`	GLua language server setup and tooling workflows for .lua files	glua_ls from the latest Pollux12/gmod-glua-ls GitHub release

Claude Code install

From inside Claude Code:

/plugin marketplace add AmyJeanes/gmod-agent-plugins
/plugin install glua-lsp@gmod-agent-plugins

Each plugin's README documents which external binaries it needs.

Codex install

From Codex CLI, add this repository as a local marketplace and install the plugin:

codex plugin marketplace add C:\path\to\gmod-agent-plugins
codex plugin add glua-lsp@gmod-agent-plugins

Start a new Codex session after installing so the bundled skills are visible.

Project-scoped install

To have collaborators on a specific project be auto-prompted to install these plugins, add to that project's `.claude/settings.json`:
