A Claude Code marketplace + plugin for building, testing, and deploying Lua AI agents directly from inside your Claude Code session.

Install

/plugin marketplace add lua-ai-global/claude-code-lua-plugin
/plugin install lua-agent-builder@claude-code-lua-plugin
/reload-plugins

Then /lua-auth to authenticate (email + OTP, or paste an existing API key from admin.heylua.ai), and /lua-doctor to verify the full environment.

Once it's on the official Anthropic marketplace, install will simplify to:

/plugin install lua-agent-builder@claude-plugins-official

What's inside

This repo is a marketplace catalog that ships one plugin:

Plugin	Description
lua-agent-builder	The full Lua agent toolchain — 14 slash commands, 5 subagents, 9 hooks, MCP server with 5 read-only platform tools

See plugins/lua-agent-builder/README.md for the plugin's own docs (layout, hooks list, slash commands, design rationale).

Quick walkthrough

After install + /lua-auth:

/lua-architect I want to build a refund-handling agent
   → drafts a plan: persona, primitives, integrations, build order
/lua-init       → scaffolds project, asks for name + org + model
/lua-new tool refund_lookup
   → spawns lua-skill-builder, scaffolds + compiles + tests
/lua-test       → exercises the tool in sandbox
/lua-deploy     → ships to production with a single permission gate

For a fuller end-to-end walkthrough see the plugin's README and /lua-doctor (5-step environment diagnostic).

Safety contracts

The plugin enforces several gates that show up at install time via /lua-doctor Step 5:

• §3.3 deploy gate — bare lua deploy is denied at the permissions layer; defense-in-depth via the confirm-deploy.mjs PreToolUse hook.
• --auto-deploy block — denied at permissions + blocked at the hook layer.
• §3.7 single-permission contract — each slash asks at most one prompt (multi-step diagnostic slashes use the documented x-lua-multi-step: true opt-out).
• Credential isolation — API key never enters the Claude conversation transcript; /lua-doctor Step 4 uses an authenticated metadata probe (lua agents --json --ci), not a key-printing command.

See plugins/lua-agent-builder/SECURITY.md for the disclosure path and a fuller scope statement.

Contributing

Issues and PRs welcome. The plugin has 16 structural lint scripts that catch known regression classes — if your change adds a new bug class, the right fix is usually "add a lint guard so the next person doesn't repeat it." See plugins/lua-agent-builder/scripts/lint-*.mjs for examples.
