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 | $0.00074 | $0.00401 |
| Opus 5.5 | $0.00030 | $0.00160 |
| Sonnet 5.5 | $0.00015 | $0.00080 |
| Haiku 4.5 | $0.00007 | $0.00040 |
Grade A, and why
docker-guide 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 7d 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 Coding Guidelines
Build small, reproducible Docker images with explicit runtime permissions and validated health behavior.
Essentials
- Build optimization - Multi-stage builds, small base images (alpine/distroless), see references/multi-stage-builds.md
- Security - Least privilege, externalize secrets (never in images), see references/security.md
- Configuration - Externalize config via env/volumes, pin versions, see references/production-config.md
- Quality - Use BuildKit and hadolint, see references/production-config.md
Gotchas
- Multi-stage builds need explicit
COPY --from=<stage>: forgetting it copies the whole heavy stage into the final image ENTRYPOINT+CMDinteract:CMDprovides default args toENTRYPOINT; overridingCMDfromdocker rundrops them, not appends
Progressive disclosure
- Read references/multi-stage-builds.md - Load when creating production images or optimizing build process
- Read references/security.md - Load when hardening images or handling secrets
- Read references/production-config.md - Load when adding health checks or configuring for orchestration
- Read references/docker-compose.md - Load when defining multi-service local development environments
What ships with it
8 files 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.

docker-guide is a skill published in the GitHub repository xonovex/platform (6 stars, last pushed 5d ago), licensed MIT. It adds 74 tokens to every session and 401 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-08.

harbor
CLI toolkit for managing containerized LLM services. Use when the user wants to start, stop, configure, or manage AI/LLM services like Ollama, Open WebUI, llama.cpp, vLLM, LiteLLM, ComfyUI, and 250+ others. Triggers on requests to "run a model", "start ollama", "set up an LLM", "configure harbor", "manage services"…
agentbox-info
Spin up isolated sandboxes ("boxes") for coding agents, run them in parallel, queue background runs with -i, and push commits safely through the host relay. Use when the user wants to run Claude Code / Codex / OpenCode in a sandbox, start more boxes, attach to a running box, or otherwise operate the agentbox CLI on…
04-security
A security and operations guide for deploying Dify, an open-source platform for building AI applications, in production.
agentbox
Fork the current agent session into a new VM or local Docker container with all the project files, agent settings and session teleported into.
deployment
Use when taking an app from source to live: choosing the deploy target from requirements (Hetzner+Coolify vs Vercel vs a third), then wiring container → CI → registry → host with build secrets, healthchecks and rollback. NOT one platform's mechanics (that is coolify, vercel, railway, render), NOT the Dockerfile alone…
docker
Use when authoring or auditing a Dockerfile, shrinking a bloated image, hardening a container that runs as root, picking a base image, or wiring a Compose dev loop with hot reload. NOT CI builds or deploy-to-host (that is deployment), NOT k8s autoscaling (that is scaling), NOT app-level injection or secrets-in-code…
