# Isolated sandboxes. Spawn an agent, get a PR.

Every task gets its own sandbox with its own services. Nothing an agent does can reach production. Tasks run in parallel and overnight - your backlog moves without waiting for a free sprint slot.

## Features

### Its own everything

A session gets a fresh checkout and its own services, never a share of yours. When the session closes, the sandbox goes with it.

Ask your agent: "Spawn an agent to fix the broken mobile menu." (MCP tools: `task_agent`, `get_agent_session`)

### Pull requests, not surprises

Every change arrives as a pull request with a live preview. Nothing merges itself, your team stays the gate.

Ask your agent: "Which branch did the agent push to?" (MCP tools: `get_agent_session`)

### Idle costs you nothing

Run several at once and leave them overnight. An idle session snapshots its workspace and releases the sandbox, then picks up where it left off when you reply.

Ask your agent: "Analyze repo against bugs #423, #424, #425 and write a report." (MCP tools: `task_agent`, `list_agent_sessions`)

### Talk to your codebase over MCP

Hand off tasks and ask questions from your IDE or any MCP platform. The sandbox knows your repo.

Ask your agent: "Start an agent to add rate limiting to the api." (MCP tools: `task_agent`)

### Pick the model

Choose which model handles each workflow. Routine tasks run cheap, heavyweight models work where they earn it.

Ask your agent: "Which models can I run agents on?" (MCP tools: `list_agent_models`)

### Custom agents

Define your own agents with their own triggers and playbooks. Your team decides what runs itself next.
