AI Assistant Plugins

Dockerman publishes a plugin that bundles the dockerman-cli skill. The plugin is a convenience guide, not an authoritative API contract. It may lag the installed CLI; assistants must prefer live dockerman --help, dockerman schema, and observed JSON output.

Claude Code install

In Claude Code:

/plugin marketplace add mandocker/skills
/plugin install dockerman

That registers the marketplace at github.com/mandocker/skills and installs the dockerman plugin into your user scope. Claude Code picks up the skill on the next session — no restart, no config edit. The skill is namespaced as dockerman:dockerman-cli.

To verify:

/plugin list

You should see dockerman enabled. Try a prompt like "List my running containers" and Claude should reach for dockerman container list.

Codex plugin install

Codex uses its own plugin marketplace command, not Claude Code's /plugin marketplace ... slash command. First register the Dockerman marketplace in Codex:

codex plugin marketplace add mandocker/skills

Then open Codex and run:

/plugins

In the plugin UI, open the Dockerman marketplace, then install and enable the Dockerman plugin. Start a new session after installing. The plugin loads the dockerman-cli skill and triggers automatically on Docker, Compose, Kubernetes, kubectl, container, image, and volume prompts.

If your Codex version does not expose the plugin UI yet, upgrade Codex first; this page only documents the plugin marketplace install path.

What you get

This repository provides a single skill, dockerman-cli, which covers:

• A pushy SKILL description so the assistant triggers it on Docker / Compose / Kubernetes / kubectl prompts even when the user does not say "dockerman".
• Guidance for the main command groups. The installed CLI's top-level map also includes network, volume, host, system, and hub; dockerman --help is authoritative.
• Critical output-shape notes — for example that dockerman k8s pod list returns { forbidden, items, truncated } with flattened fields (.name, .namespace, .restarts, .status), not the kubectl-shaped metadata.* tree.
• The two k8s scoping rules that catch every first attempt: --cluster is required when no cluster is selected, and pod list without --namespace returns only the default namespace (silently misses kube-system).
• Destructive-action guidance. container restore requires confirmation; container backup itself does not require -y.
• A jq cookbook (references/output-parsing.md) for projecting JSON output without flooding context.

Update or remove

Claude Code:

/plugin update dockerman
/plugin uninstall dockerman

Updates pull the latest version from the marketplace's plugin.json. The plugin lives at ~/.claude/plugins/ — uninstalling removes it cleanly.

Codex:

codex plugin marketplace upgrade dockerman

To remove the marketplace:

codex plugin marketplace remove dockerman

Pin to a specific revision

For Claude Code, append @<git-ref> (branch, tag, or commit SHA) to the marketplace URL:

/plugin marketplace add mandocker/skills@v1.0.0
/plugin install dockerman

For Codex, append @<git-ref> to the marketplace source:

codex plugin marketplace add mandocker/skills@v1.0.0

Use this when you want a reproducible setup for a team — every member gets the same revision until you bump the pin.

Claude Code team setup

To auto-install for everyone on a project, add the marketplace to .claude/settings.json at the repo root:

{
  "extraKnownMarketplaces": {
    "dockerman": {
      "source": {
        "source": "github",
        "repo": "mandocker/skills"
      }
    }
  }
}

Teammates running /plugin install dockerman will see it under the registered marketplace without having to add it themselves.

Other agents

The skill files live at github.com/mandocker/skills/tree/main/skills/dockerman-cli. Any agent harness that reads Claude-style skill files (Cursor, the Anthropic Agent SDK, etc.) can clone the repo and point at that path directly.
