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 | $0.00093 | $0.01042 |
| Opus 5 | $0.00046 | $0.00521 |
| Sonnet 5 | $0.00019 | $0.00208 |
| Haiku 4.5 | $0.00009 | $0.00104 |
Grade A, and why
docker-docs 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.
How it starts
The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Docker
Docker is a platform for developing, shipping, and running applications in containers. Containers package code with all dependencies, ensuring consistent behavior across environments.
Version: Docker 28.x (Engine) / Docker Compose v2

Core Concepts
- Image: Read-only template with code, libraries, and dependencies
- Container: Running instance of an image with its own filesystem, network, and process space
- Dockerfile: Text file with instructions to build an image
- Docker Compose: Tool for defining multi-container applications
- Registry: Storage for images (Docker Hub, private registries)
- Volume: Persistent storage that survives container removal
- Network: Virtual network for container communication
- BuildKit: Modern build backend with caching, parallelism, and multi-platform support

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-docs is a skill published in the GitHub repository pledgeandgrow/pledge-skills (10 stars, last pushed 1mo ago), licensed MIT. It adds 93 tokens to every session and 1,042 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.
