What it does
Docker Mastery is an agent skill from tctinh/agent-hive. Use when working with Docker containers — debugging container failures, writing Dockerfiles, docker-compose for integration tests, image optimization, or deploying containerized applications
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud, covering Containers. It works with Docker.
When your agent uses it
- Working with Docker containers — debugging container failures
- Writing Dockerfiles
- Docker-compose for integration tests
- Image optimization
Example prompts
- “/docker-mastery”
Requirements
- Node.js
- Docker
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Check the image (what's installed?)
- Check mounts (what host files are visible?)
- Check environment variables (what config is passed?)
- Check the Dockerfile (how was it built?)
What it can do on your machine
Read from SKILL.md and the folder at commit b3f11c0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dockerdocker-composenodenpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
POSTGRES_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Docker Mastery loads about 2.6k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 984 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:223
.env
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 984 words (~2,634 tokens).
“Docker is a platform for building, shipping, and running applications, not just isolation.”
