docker.shrink_container

docker.shrink_container is a skill for Claude Code from gpsaggese/helpers. It costs 14 tokens per session (96 once invoked), scanned A, original, Apache-2.0.

A Docker optimization skill that proposes ways to make a project's Docker container smaller and faster without changing what it does. Docker containers package an application and its environment for consistent running.

In plain words
What is it for?
Use it to review a project directory, suggest container-size and speed changes, and state the expected improvement and behavior-preservation check for each proposal.
Why use it?
Large or slow containers take more storage, time, and resources to build or start. The skill focuses on possible improvements while checking that existing behavior is preserved.

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.shrink_container 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 it actually says

Goal

  • Act as an expert in Docker
  • Given a directory <TARGET> with a project, propose solutions to make its Docker container faster and smaller without changing its functionality

Verification

  • Confirm each proposed change preserves the container's existing functionality
  • Confirm each proposal states its expected size or speed improvement
Changes

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.
