# docker-destructive-guardrails

The skill makes the agent name exactly what will be deleted and get your confirmation before any destructive Docker command runs.

## What it does

The skill activates when you say "clean up", "start fresh", "wipe everything" or when the agent itself reaches for `docker rm`, `docker container prune`, `docker system prune`, `docker rmi`, `docker network prune`, `docker builder prune`, `docker context rm` and similar. Instead of deleting first, it lists what is lost and waits for your answer.

One carve-out exists: a container the agent created this session for testing and already stopped gets removed without a blocking question. `docker kill` and `docker container prune` do not qualify — prune always sweeps every stopped container on the host, not just the one you are cleaning up. `docker stop` removes nothing, but it interrupts a process and discards unpersisted state, so on containers the agent did not create it still asks first.

This is a behavioral guardrail, not a Dockerfile or Compose authoring skill. Destructive commands inside a Compose project belong to `docker-compose-patterns`. If the task is not about the Docker CLI, this skill stays out of the way.

## Requirements
- Works with: Docker

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install docker/skills docker-destructive-guardrails
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add docker/skills --skill docker-destructive-guardrails -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-destructive-guardrails/SKILL.md

## When to use it
- remove a container without losing data silently
- stop a stuck container and know what state goes with it
- clear the build cache without wiping tagged images
- delete unused networks and volumes on purpose
- tell the agent when container removal needs no confirmation

## Example prompts
- clean up Docker, but tell me what you're deleting first
- remove the stopped containers — what data do I lose?
- reset the build cache, just don't touch tagged images

name: docker-destructive-guardrails
description: Use this skill before running, or recommending, any Docker command that deletes, wipes, resets, or otherwise irreversibly changes state — even if the user just says to "clean up", "clear the cache", "start fresh", "wipe everything", "nuke it", "reset", "force remove", or "tear down" Docker resources. Covers generic Docker CLI destructive operations not owned by a more specific skill — `docker rm`, `docker rm -f`, `docker container prune`, `docker kill`, `docker system prune`, `docker rmi`/`docker image rm`, `docker image prune -a`, `docker network rm`, `docker network prune`, `docker builder prune`, `docker buildx rm`, `docker context rm`, and standalone (non-Compose) `docker volume rm`/`docker volume prune`. Also indexes destructive commands owned by other Docker skills (Compose, sandbox, Desktop). Core rule — state exactly what will be lost and get explicit confirmation first, except narrow, low-friction Tier 1 container cleanup.

# Docker Destructive Command Guardrails

## Overview

This skill provides the cross-product policy for handling destructive or irreversible Docker CLI operations: commands that delete data, remove resources, or otherwise cannot be undone. Use it whenever a task could reasonably lead to running one of these commands, even if the user never names the command directly. It covers the generic Docker CLI commands with no home in a more specific skill, and it indexes where other destructive commands (Compose, sandbox, Desktop) are documented.

## When to use this skill

Activate this skill when:

- The user asks to "clean up", "clear the cache", "start fresh", "wipe everything", "nuke it", "reset", "force remove", or "tear down" Docker resources without naming a specific command
- The agent is considering `docker rm`, `docker rm -f`, `docker container prune`, `docker kill`, `docker stop`, `docker system prune`, `docker rmi`, `docker image rm`, `docker image prune -a`, `docker network rm`, `docker network prune`, `docker builder prune`, `docker buildx rm`, `docker context rm`, or standalone (non-Compose) `docker volume rm`/`docker volume prune` as a fix for an unrelated problem (disk space, a stuck container, a stale network, a broken build cache, an old builder or volume)
- The user wants a cross-product overview of destructive commands across Docker skills
```
