AI AGENT

An AI Agent That Handles Multi-Step Tasks Autonomously

Send one prompt and the AI plans, executes, and verifies. The ReAct pattern lets it run code, generate files, search the web, and complete research tasks end-to-end.

Reasoning + Acting — AI completes tasks on its own

The AI Agent uses the ReAct (Reasoning + Acting) pattern, alternating between thinking, acting, and observing to handle complex tasks. A cloud Linux sandbox sits behind it — Python code is generated, executed, and the next step is chosen from the result, all in one conversation. The same agent can also be invoked from real-time character chat as a background sub-agent, so the voice conversation keeps flowing while heavier research or code execution runs behind the scenes. Free tier on Gemini Flash-Lite (10/day); top-tier models (Claude / GPT / Gemini Pro, etc.) on paid plans.

Autonomous task planning

Given a goal, the agent breaks it down into steps and orders them itself.

Code generation and execution

Writes Python code, runs it instantly in a cloud Linux sandbox, and folds results plus generated files back into the conversation.

Tool integration

Combines custom tools (web search, API calls, etc.) to complete the task.

Visible progress

Thought / Action / Observation streams live so you can see exactly what the agent is doing.

Background sub-agent from character chat

During real-time voice chat, the character can hand off heavy work to the agent in the background — they reply briefly, and the deeper result is appended to the chat once it's ready.

Basic usage

1

Open AI Chat

Launch "AI Chat" from the sidebar. The agent lives as a mode inside AI Chat.

2

Turn on agent mode

Toggle the ReAct mode switch at the top of the chat screen to switch from normal chat to the agent.

3

Pick model and tools

Choose the AI provider (Anthropic / OpenAI / DeepSeek, etc.) and the custom tools the agent can call.

4

Send one prompt

The agent plans, executes, and formats results on its own. Thought / Action / Observation streams live so you can see what it does.

Pairs with other features

The AI agent shines when combined with AI Chat, custom tools, and the Linux runtime — that's where it does real work.
