Review Docker and container security audit patterns. An agent skill from IgorWarzocha/Opencode-Workflows.

  • Auditing secrets in layers
  • SKILL.md covers Secrets in Images (Critical), Port Exposure, Non-Root User and Multi-Stage Builds, plus 4 more sections
  • Runs Shell scripts from its folder; calls rg, docker and jq; needs AWS_SECRET_ACCESS_KEY and API_KEY
  • Tasks that involve Containers

What it does

Security Docker is an agent skill from IgorWarzocha/Opencode-Workflows. Review Docker and container security audit patterns. Use for auditing secrets in layers, port exposure, and non-root users. Use proactively when Dockerfile or docker-compose.yml is present. Examples: - user: "Audit this Dockerfile" → check for secrets in ENV/ARG and non-root USER - user: "Review docker-compose ports" → find accidentally exposed databases - user: "Check for secrets in image history" → audit layers and build artifacts - user: "Optimize Docker security" → implement multi-stage builds and minimal…

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/scan.sh`).

It sits in DevOps & Cloud, covering Containers. It works with Docker. The repository describes itself as: An ever evolving repository of Opencode workflow examples that might enhance your experience with it. I only left the stuff that actually works. YMMV.

When your agent uses it

  • Auditing secrets in layers
  • Tasks that involve Containers

Example prompts

  • “Audit this Dockerfile”
  • “Review docker-compose ports”
  • “Check for secrets in image history”
  • “/security-docker”

Requirements

  • Node.js
  • A Bash shell
  • Docker
  • A credential in API_KEY
  • A credential in AWS_SECRET_ACCESS_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 6444ec4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • rg
    • docker
    • jq
    • trivy

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • AWS_SECRET_ACCESS_KEY
    • API_KEY
    • POSTGRES_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Security Docker loads about 1.6k tokens when it runs. Until then it costs about 158 tokens; SKILL.md has 131 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~158
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 131 words (~1,553 tokens).

“Security audit patterns for Docker and container deployments covering secrets in images, port exposure, user privileges, and compose security.”

Security Docker fits situations like: auditing secrets in layers; tasks that involve Containers.

How do I install Security Docker in Claude Code?

Run `npx skills add IgorWarzocha/Opencode-Workflows --skill security-docker -a claude-code`. Or copy the skill folder (agents/security-reviewer/.opencode/skill/security-docker in IgorWarzocha/Opencode-Workflows) into .claude/skills/security-docker in your project. Claude Code loads it when a task matches its description.

How do I install Security Docker in Codex?

Or copy the skill folder (agents/security-reviewer/.opencode/skill/security-docker in IgorWarzocha/Opencode-Workflows) into .agents/skills/security-docker in your project. Codex loads it when a task matches its description.

Can I use Security Docker in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add IgorWarzocha/Opencode-Workflows --skill security-docker -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/security-docker, .gemini/skills/security-docker, .github/skills/security-docker and .opencode/skills/security-docker in your project.

What does Security Docker need to run?

Going by SKILL.md and its folder, Security Docker needs a shell for the scripts in its folder, the command-line tools its instructions call (rg, docker, jq and trivy) and credentials named AWS_SECRET_ACCESS_KEY, API_KEY and POSTGRES_PASSWORD. Our summary lists: Node.js; A Bash shell; Docker; A credential in API_KEY; A credential in AWS_SECRET_ACCESS_KEY.

Does Security Docker access the network?

SKILL.md contains no URLs. Its commands use docker, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Security Docker safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Security Docker use?

No licence was found for Security Docker or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Security Docker use?

About 1.6k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Security Docker?

Skills that share tags, products or a category with Security Docker: Iron Proxy Gateway for NanoClaw (nanocoai/nanoclaw, 31k stars), GreptimeDB Dev Docker Image (GreptimeTeam/greptimedb, 6.7k stars), Senior DevOps Toolkit (maslennikov-ig/claude-code-orchestrator-kit, 259 stars) and LangBot Deployment Guide (langbot-app/LangBot, 18k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
