docker is a cursor rule for Cursor from lacymorrow/paperclip-hub. It costs 0 tokens per session (407 once invoked), scanned A, original, MIT.

Docker guidelines explain how to build, configure, secure, and run Docker containers, which package software and its dependencies into portable units.

In plain words
What is it for?
Use them when writing Dockerfiles, managing images and dependencies, setting environment variables, configuring services, and preparing production containers.
Why use it?
They help avoid oversized or insecure images, unreliable builds, missing configuration, and differences between development and production.

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.

Security

Grade A, and why

docker 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 yesterday.

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 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.
