We're releasing the first major addition to the Harbor task format: multi-step tasks.

A multi-step task runs an agent through a sequence of ordered steps against a single, shared environment. Each step has its own instruction and verifier.

Multi-step tasks are helpful when implementing long-horizon tasks with early stopping conditions, testing continual learning methods like memory, and observing an agent's ability to build on its prior work.

```text theme={"system"}
task.toml
environment/
  Dockerfile
steps/
  step-one/
    instruction.md
    workdir/
      setup.sh
      ...
    tests/
      test.sh
    solution/
      solve.sh
  step-two/
    instruction.md
    ...
tests/
  test.sh
```

Install Harbor 0.5.0 or newer to use multi-step tasks:

```bash tab="uv" theme={"system"}
uv tool install "harbor>=0.5.0"
```

```bash tab="pip" theme={"system"}
pip install "harbor>=0.5.0"
```

Learn more in the [multi-step tasks documentation](/core-concepts/tasks/multi-step), or have your coding agent guide you through the process of creating a multi-step task by downloading our `create-task` skill:

```bash theme={"system"}
npx skills add harbor-framework/harbor --skill create-task
```

We're excited to see the multi-step tasks Harbor users build!
