# Jaccard

> Jaccard is an AI agent framework and managed backend. Built for long-horizon agents: progress survives pauses and interruptions, and tools run in an isolated sandbox.

Jaccard is in early access. Agents are taking on work that outlasts a single session: they run for hours and pause for people. You define an agent in Markdown and code, deploy it with `jaccard deploy`, and Jaccard runs it.

## How Jaccard works

- Define your agent. Deploy it. Write instructions and skills in Markdown. Add custom tools in code, then deploy on Jaccard.
- Run code in isolation. Define your sandbox once. Jaccard provisions it when your tools need it and reuses it within the session.
- Pause and resume. Wait for human approval or an external event. Pick up where the agent left off.

## The building blocks for production agents

- Durable execution: Preserve progress between steps. Resume after a pause or interruption.
- Sandboxes: Give your tools an isolated workspace to run code and work with files.
- Model choice: Choose the model that fits your agent.
- Channels: Connect the same agent to Slack and your own applications.
- Schedules: Run recurring tasks automatically, from daily reports to weekly reviews.
- Configuration in code: Configure your agent and its sandbox in code, versioned with your project.
