docker

A set of instructions for building and running applications in Docker, a tool that packages software with its required environment.

In plain words
What is it for?
Use it to containerize applications, create multi-stage Docker images, configure Docker Compose services, and plan container-based deployments.
Why use it?
It helps make applications behave more consistently across computers and deployments. It also guides image optimization and multi-container setups.

Command for Cursor

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 438 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/docker

Docker containerization, multi-stage builds, Docker Compose, and container best practices. Used for containerizing applications, optimizing images, or designing container-based architectures.


⚠️ CURSOR OUTPUT CONTRACT

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `docker-developer`** | Skills: `clean-code, bash-linux, deployment-procedures, server-management`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

Required Behavior

  1. Read the agent's full instructions from .windsurf/agents/docker-developer.md (or .cursor/rules/agents/docker-developer.mdc)
  2. Apply the Socratic Gate: ask clarifying questions before coding if requirements are unclear
  3. Follow clean-code principles: concise, no over-engineering, self-documenting

$ARGUMENTS


🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `docker-developer`** | Skills: `clean-code, bash-linux, deployment-procedures, server-management`

Task

Containerize applications with Docker for development and production.

Steps:

  1. Dockerfile Design

    • Base image selection
    • Multi-stage build
    • Security hardening
    • Layer optimization
  2. Compose Setup

    • Service definitions
    • Network configuration
    • Volume mounts
    • Health checks
  3. Optimization

    • Image size reduction
    • Layer caching
    • Build context
    • .dockerignore
  4. Security

    • Non-root user
    • Read-only filesystem
    • Secret management
    • Scanning

Usage Examples

/docker containerize Node.js app
/docker optimize image size
/docker setup Docker Compose for dev
/docker harden container security
/docker build multi-arch images
/docker setup CI/CD with Docker
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docker is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 438 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
