## What it does

This skill covers the operational half of Docker Agent. It explains how to invoke `docker agent run` against a local config, an alias, or a registry reference, how much autonomy to hand the agent over tool calls, and why a run dies. Published by docker under Apache-2.0. It assumes the `agent.yaml` already exists.

There are four `--safety` modes. `strict` asks before every tool call, `balanced` auto-approves safe ones and asks about the rest, `restricted` auto-approves safe calls and denies everything else, and `autonomous` approves all of it — the same as `--yolo`. For anything unattended, such as cron or CI, take `restricted`, so an unexpected tool call fails closed instead of running unreviewed. You can bake a mode into an alias, though an explicit flag on the command line overrides it.

The `--sandbox` flag runs the agent inside an isolated microVM managed by the `sbx` CLI, which is a separate prerequisite you install and configure first. Network access is default-deny: only the model provider, `models.dev`, and hosts the toolset resolver can infer are open, so a third-party API usually needs an entry added with `docker agent sandbox allow`. One caveat worth knowing — a local stdio MCP server runs as a host process outside the VM, so treat it as trusted. Sandboxes also persist and get reused across runs from the same workspace, so a clean VM every time is not what you get. `--worktree` cannot be combined with `--remote` or `--sandbox`.

## Requirements
- Works with: Docker

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-agent-run -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/docker-agent-run/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/docker-agent-run/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-agent-run -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/docker-agent-run/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-agent-run -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/docker-agent-run/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install docker/skills docker-agent-run
```

2. **Manually: put the files in place**
- File: `.github/skills/docker-agent-run/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-agent-run -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/docker/skills --path skills/docker-agent-run
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/docker-agent-run/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-agent-run -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/docker/skills/tree/HEAD/skills/docker-agent-run/SKILL.md

## When to use it
- pick an approval mode for an unattended agent run
- keep an agent's file edits inside a separate git worktree
- let a third-party API through the sandbox network policy
- work out why the agent cannot see an API key
- register a short alias instead of a long config path

## Example prompts
- run the agent from ./agent.yaml in restricted mode
- why can't my sandboxed agent see my API key
- add api.example.com to the sandbox allowlist

name: docker-agent-run
description: Use this skill when running a Docker Agent with `docker agent run`, choosing a safety/approval mode, using the `--sandbox` isolation flag, setting up aliases, or troubleshooting a run (missing credentials, worktrees). Even if the user just says they want to "run my agent", "make my agent auto-approve tool calls", "run this agent safely", or "why can't my agent see my API key", this skill applies. Covers `--safety` (strict/balanced/restricted/autonomous), `--yolo`, `--sandbox` and its network allowlist, `--worktree`, `docker agent alias`, and `docker agent doctor`.
license: Apache-2.0
compatibility: Requires the docker-agent CLI plugin (Docker Desktop 4.63+, or standalone via Homebrew/GitHub releases). Sandbox mode (`--sandbox`) additionally requires the `sbx` CLI. Verified against docker-agent as shipped with Docker CLI 29.7.2.

# Docker Agent: Running and Operating Agents

## Overview
This skill owns the operational side of Docker Agent: invoking `docker agent
run` against a local config, an alias, or a registry reference; choosing how
much autonomy the agent gets over tool calls; isolating it in a sandbox VM;
and diagnosing why a run fails. It assumes the `agent.yaml` already exists —
see Related skills for authoring it.

## When to use this skill
Activate this skill when:
- The user wants to run an agent interactively or headlessly (`--exec`).
- The user is choosing or debugging `--safety`, `--yolo`, or approval behavior for tool calls.
- The user wants to isolate an agent's shell/filesystem access with `--sandbox`, or hit a sandbox network-policy error.
- The user wants a reusable shortcut (`docker agent alias`), a scoped git worktree (`--worktree`), or is debugging credentials/model availability (`docker agent doctor`).

## Do not use this skill when
Do not use this skill when:
- The task uses standalone `sbx run/create/stop/rm` rather than
  `docker agent run --sandbox` — use `docker-sandboxes-lifecycle`.
- The task is standalone `sbx policy` or `sbx secret` configuration — use
  `docker-sandboxes-network-credentials`. Establish which CLI is in use
  before recommending commands when the request only says "my sandbox".
- The task is writing or editing the `agent.yaml` itself (models, toolsets, sub_agents) — use `docker-agent-config`.
