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 | $0.00025 | $0.00445 |
| Opus 5 | $0.00013 | $0.00222 |
| Sonnet 5 | $0.00005 | $0.00089 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
docker-management 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 6d 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 Management
Use this for container lifecycle operations, Compose stacks, image builds, logs, disk cleanup, and Dockerfile review.
First Checks
docker --version
docker compose version
docker info
If Docker is not running, stop and report that instead of guessing.
Common Tasks
| Task | Command |
|---|---|
| Running containers | docker ps |
| All containers | docker ps -a |
| Logs | docker logs --tail 100 <name> |
| Follow logs | docker logs --tail 100 -f <name> |
| Shell | docker exec -it <name> /bin/sh |
| Inspect | docker inspect <name> |
| Stats | docker stats --no-stream |
| Compose status | docker compose ps |
| Compose logs | docker compose logs --tail 100 |
| Disk usage | docker system df |
Debugging Flow
- Identify the failing container or service.
- Check status and exit code with
docker ps -aordocker compose ps. - Read logs from the failing service only.
- Inspect env, mounts, ports, healthcheck, restart policy, and network.
- Reproduce with the smallest command or Compose service.
- Fix the image/config and rebuild.
Dockerfile Review
Check for:
- Pinned base image and runtime versions.
- Multi-stage builds for compiled/bundled apps.
- No secrets in
ARG,ENV, layers, or copied files. - Non-root runtime user.
- Small runtime image and explicit healthcheck where useful.
- Dependency install before source copy when caching matters.
Cleanup Safety
Never run destructive cleanup without checking impact:
docker system df
docker image prune
docker container prune
Ask before docker system prune -a --volumes; it can remove data and rebuild caches.
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-management is a skill published in the GitHub repository metaspartan/cybara (26 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 445 once invoked, about $0.0001 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 2026-08-30.
