What it does
Env Check is an agent skill from ericboy0224/learn-docker-and-k8s. Check if the system is ready for the Learn Docker & K8s game. Verifies Docker, Docker Compose, kubectl, kind, disk space, and port availability. Use when the user asks about requirements, setup, or environment issues.
Its SKILL.md is about 360 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 Container orchestration and Containers. It works with Docker and Kubernetes. The repository describes itself as: Interactive AI-driven game to learn Docker, Linux, networking & Kubernetes. Open in Claude Code or Cursor, type 'let's play'.
When your agent uses it
- The user asks about requirements
- Environment issues
Example prompts
- “/env-check”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit da325b6. 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:
dockerbash
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.docker.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Env Check loads about 358 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 151 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.
- NoteRuns commands with sudoSKILL.md:28
not running → "Start Docker Desktop" or `sudo systemctl start docker`
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 151 words (~358 tokens).
“Run the environment check script and report results to the player in a friendly way:”
- name
- env-check
- argument-hint
- [--full]
