What is docker-expert?

A Docker specialist for building images and running groups of containers with Docker Compose. It also examines container security and production deployment choices.

It reviews or rewrites Dockerfiles and Compose files, including multi-stage builds, image slimming, security hardening, and orchestration.

It helps reduce oversized images, slow builds, fragile container setups, and avoidable security risks. It is not for Kubernetes, CI/CD pipelines, or cloud-provider container services.

Token cost

What it costs to keep this loaded

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	$0.00125	$0.02932
Opus 5.5	$0.00050	$0.01173
Sonnet 5.5	$0.00025	$0.00586
Haiku 4.5	$0.00013	$0.00293

Security

Grade A, and why

docker-expert scanned grade A with 1 finding 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 today.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
