pp-fellow-stagg-ekgControl a Fellow Stagg EKG kettle over its local HTTP CLI. An agent skill from mvanhorn/printing-press-library.
Pp Fellow Stagg Ekg is an agent skill from mvanhorn/printing-press-library. Control a Fellow Stagg EKG kettle over its local HTTP CLI. Trigger phrases: start the kettle, set the kettle to 95, show kettle status, turn the kettle off, use fellow stagg ekg, run fellow stagg ekg.
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
npxgoFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Pp Fellow Stagg Ekg loads about 697 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 163 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.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, BashAutomated 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.

Run `npx skills add mvanhorn/printing-press-library --skill pp-fellow-stagg-ekg -a claude-code`. Or copy the skill folder (cli-skills/pp-fellow-stagg-ekg in mvanhorn/printing-press-library) into .claude/skills/pp-fellow-stagg-ekg in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mvanhorn/printing-press-library --skill pp-fellow-stagg-ekg -a codex`. Or copy the skill folder (cli-skills/pp-fellow-stagg-ekg in mvanhorn/printing-press-library) into .agents/skills/pp-fellow-stagg-ekg in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mvanhorn/printing-press-library --skill pp-fellow-stagg-ekg -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pp-fellow-stagg-ekg, .gemini/skills/pp-fellow-stagg-ekg, .github/skills/pp-fellow-stagg-ekg and .opencode/skills/pp-fellow-stagg-ekg in your project.
Going by SKILL.md and its folder, Pp Fellow Stagg Ekg needs the command-line tools its instructions call (npx and go). Our summary lists: Node.js. Its frontmatter pre-approves these tools: Read, Bash.
SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Pp Fellow Stagg Ekg is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 697 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
