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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01148 |
| Opus 5 | $0.00046 | $0.00574 |
| Sonnet 5 | $0.00018 | $0.00230 |
| Haiku 4.5 | $0.00009 | $0.00115 |
Grade A, and why
container-manager-swarm 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Docker Swarm Orchestration
Domain-typed control of a Docker Swarm cluster through the container-manager-mcp server. These operate the cluster control plane (services + nodes) and must be aimed at a swarm manager node.
When to use
- Inventory swarm nodes (role/availability/status) and services (image/replicas/ports).
- Create a replicated service, or remove one.
- Initialize a swarm or make a node leave it.
When NOT to use
- Single-host container/image lifecycle or
exec/logs →container-manager-lifecycle. - Plain
docker-composestacks (non-swarm) →cm_compose_operationsin the lifecycle skill. - Kubernetes →
container-manager-kubernetes-operations, not these tools. If the target is a Kubernetes cluster,cm_swarm_operations action=list_nodes/list_servicesare the wrong tools entirely — they only understand Docker Swarm's control plane, not the Kubernetes API.
Prerequisites & environment
Connect via the mcp-client skill against the container-manager-mcp MCP server.
Cluster reads/writes MUST target a swarm manager — pass its host alias.
| Variable | Required | Notes |
|---|---|---|
CONTAINER_MANAGER_TYPE |
optional | docker (Swarm is a Docker feature) |
CONTAINER_MANAGER_HOST |
optional | Default manager alias (else pass host explicitly) |
Call cm_list_hosts to see aliases; a swarm-manager alias is required for
list_nodes / list_services / create_service / remove_service.
Tools & actions
| Condensed tool | Actions |
|---|---|

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

container-manager-swarm is a skill published in the GitHub repository Knuckles-Team/container-manager-mcp (5 stars, last pushed 12d ago), licensed MIT. It adds 91 tokens to every session and 1,148 once invoked, about $0.0005 per session on Opus 5. 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.
