Select environment: › 🔧 Sandbox (edit and test) 🚀 Production (view and deploy versions) ``` Best for: When you're exploring options **Skip prompt and go straight to sandbox** ```bash theme={null} $ lua persona sandbox # No prompt - opens sandbox menu immediately ``` Best for: Quick edits during development **Skip prompt and go straight to production** ```bash theme={null} $ lua persona production # No prompt - opens production menu immediately ``` Best for: Fast deployments, automation \##Complete Workflow ```bash theme={null} lua persona sandbox ``` Select "Edit persona" → Opens your editor with current persona ```bash theme={null} lua chat ``` Select Sandbox mode to test persona ```bash theme={null} lua persona sandbox ``` Select "Create version" → Uploads persona as new version ```bash theme={null} lua persona production ``` Select "Deploy persona version" → Choose version and confirm deployment ## Environment Modes **Local Development & Testing** ``` ? Select environment: 🔧 Sandbox (edit and test) ``` **Actions:** * 👁️ View full persona * ✏️ Edit persona * 📦 Create version (push to production) * 📋 List versions **Storage:** Code (`LuaAgent` in `src/index.ts`) **Use for:** * Writing and editing persona * Testing before deployment * Iterating on personality **Version Management & Deployment** ``` ? Select environment: 🚀 Production (view and deploy versions) ``` **Actions:** * 👁️ View persona versions * 🚀 Deploy persona version **Storage:** Server API **Use for:** * Deploying tested versions * Rolling back if needed * Viewing version history ## Channel-Aware Personas Personas can be split per channel using an object form. The previous string form keeps working — adopt the object form only when a channel needs its own phrasing. ```typescript theme={null} new LuaAgent({ // Original string form — still works everywhere persona: 'You are a helpful assistant for Acme Corp.', }); ``` ```typescript theme={null} new LuaAgent({ // Split per channel persona: { base: 'Shared persona that applies to all channels.', voice: 'Speak naturally, no markdown, no bullet lists. Keep replies under two sentences.', text: 'Use markdown headers and bullet lists where helpful.', }, }); ``` **Resolution rules:** * `voice` channel → uses `voice` if defined, else `base`. * `text` (chat) channel → uses `text` if defined, else `base`. * A channel-agnostic operation (e.g. `lua init` source write, the agent description fallback) flattens all defined branches. **Common patterns:** * **Voice-only override** — Keep your existing string persona, add `voice` only when voice needs different phrasing: ```typescript theme={null} persona: { base: 'You are a helpful assistant for Acme Corp...', voice: 'Speak conversationally. Avoid lists and code blocks.', } ``` * **Voice-only persona** — A voice agent that only needs a voice prompt: ```typescript theme={null} persona: { voice: 'Speak conversationally. Confirm orders before placing them.' } ``` Pushing a voice-only persona (no `base`, no `text`) now correctly applies on the server. `lua sync --pull` round-trips the object form back to your source file with all channel branches preserved. The `PersonaText` type is exported from `lua-cli` if you need it in your own typings. ## Writing Great Personas ### Structure Template ```yaml theme={null} persona: | You are [ROLE] for [COMPANY].
