# Web workspace

> Work with projects, tool cards, slash commands, modes, attachments, and settings in the Fleet Prime Agent browser UI.

Start the workspace from the project directory you want the agent to work in:

```bash theme={null}
cd /path/to/your/project
fleet-agent
```

Open the printed URL (default `http://127.0.0.1:3000`).

## Projects and sessions

The workspace organizes sessions into projects bound to directories on disk. Create a project, browse to its directory, and every session you start in it runs with that working directory. Sessions persist after you close the tab; resume, rename, fork, or delete them from the session list. See [Sessions and projects](/fleet-prime-agent/concepts/sessions-and-projects).

## The composer

The composer is where you type requests and control the run:

* **Model picker** — choose the provider and model per session.
* **Thinking level** — `off`, `minimal`, `low`, `medium`, `high`, `xhigh`, or `max`.
* **Mode** — `agent` (default), `plan`, or `harness`. Plan mode tracks a plan with progress; you can execute or refine it.
* **Attachments** — attach files to the session for the agent to use.

## Tool cards

Every tool call renders as a dedicated card in the transcript:

* **IPython** — code cells with their output, backed by the session's persistent kernel.
* **Bash and Edit** — shell commands and file edits with diffs.
* **Plans and todos** — plan progress and task lists.
* **Subagents** — child agents spawned by the engine's recursive `rlm` workflow.
* **Questions** — interactive prompts you answer inline. Unanswered dialogs time out after 60 seconds.

Anything without a dedicated card falls back to a generic tool renderer.

## Slash commands

Type `/` in the composer for autocomplete over the engine's slash commands. Common ones:

* `/login` — add provider credentials.
* `/refine` — run the engine's self-improvement workflow over the session trajectory.

Autocomplete comes from `GET /api/chat/commands`; execution goes through `POST /api/chat/command`.

## Skills, prompts, and extensions

The engine's executable skills, prompt templates, and extensions are surfaced in the workspace through `GET /api/chat/resources`. They are engine features: install and author them the same way you would for a plain `prime-agent` install, and Fleet lists them per session.

## Workspace navigation

The workspace panel shows the file tree of the bound directory (`GET /api/workspace/tree`) with file previews (`GET /api/workspace/file`). Rebind the root directory from the UI (`POST /api/workspace/root`) or pick a directory with the built-in browser.

## Settings

**Settings** exposes the resolved engine settings and persists changes through the engine's settings manager (`GET`/`PATCH /api/chat/settings`). Provider management lives in **Settings → Providers**; see [Providers and models](/fleet-prime-agent/guides/providers-and-models).
