agent-hive: Skill for Claude Code

.github/skills/docker-mastery/SKILL.md

docker-mastery is a skill for Claude Code, Codex from tctinh/agent-hive. It costs 33 tokens per session (2,559 once invoked), scanned C, original, no licence file.

A set of practices for working with Docker containers, including diagnosing failures, writing Dockerfiles, configuring multi-container tests, optimizing images, and deploying containers.

In plain words
What is it for?
Use it when debugging container failures, creating Docker images, writing Docker Compose configurations, improving image size, or deploying containerized applications.
Why use it?
It helps address the common setup, testing, size, and deployment problems that arise when software runs in containers.

Skill for Claude CodeCodex

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

This is tctinh/agent-hive's own configuration. It tells Claude Code and Codex how to work on agent-hive itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-hive configures →

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 C, and why

docker-mastery scanned grade C 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 1mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

RUN apt-get update && apt-get install -y git && rm -rf /var/lib/apt/lists/*

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.
