What it does
Pu is an agent skill from srid/emanote. Provision and drive a pu box — an Incus container used as a clean Linux host for CI, builds, and evidence capture. Use when you need to run something on a fresh remote box instead of the user's machine: nix run a build, run CI against a real host, capture screenshots/video off-machine, or reproduce on a pristine environment. Covers create/connect/scp/destroy, running remote commands, copying artifacts back, and the no-egress failure mode. Triggers on "pu box", "spin up a box", "run this on a box", "ephemeral…
Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Linux. The repository describes itself as: Emanate a structured view of your plain-text notes.
When your agent uses it
- You need to run something on a fresh remote box instead of the users machine: nix run a build
- Run CI against a real host
- Capture screenshots/video off-machine
- Reproduce on a pristine environment
Example prompts
- “pu box”
- “spin up a box”
- “run this on a box”
- “/pu”
What it can do on your machine
Read from SKILL.md and the folder at commit 9d01037. 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:
nixsshscp
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.github.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
Pu loads about 822 tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 273 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.

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.

When should I use Pu?
Pu fits situations like: you need to run something on a fresh remote box instead of the users machine: nix run a build; run CI against a real host; capture screenshots/video off-machine; reproduce on a pristine environment.
How do I install Pu in Claude Code?
Run `npx skills add srid/emanote --skill pu -a claude-code`. Or copy the skill folder (.agents/skills/pu in srid/emanote) into .claude/skills/pu in your project. Claude Code loads it when a task matches its description.
How do I install Pu in Codex?
Run `npx skills add srid/emanote --skill pu -a codex`. Or copy the skill folder (.agents/skills/pu in srid/emanote) into .agents/skills/pu in your project. Codex loads it when a task matches its description.
Can I use Pu in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add srid/emanote --skill pu -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pu, .gemini/skills/pu, .github/skills/pu and .opencode/skills/pu in your project.
What does Pu need to run?
Going by SKILL.md and its folder, Pu needs the command-line tools its instructions call (nix, ssh and scp).
Does Pu access the network?
SKILL.md names 1 domain. In commands or code: api.github.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Is Pu safe to install?
Our automated static check of SKILL.md flagged 1 warning(s): mentions a credentials file (ssh keys, cloud or package-manager tokens). Read the flagged lines before installing; the check is not a guarantee either way.
What licence does Pu use?
Pu has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Pu use?
About 822 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Pu?
Skills that share tags, products or a category with Pu: Configuring Horizon (coollabsio/coolify, 63k stars), K8s Security Policies (Cybereason-Public/owLSM, 280 stars), Apple Container Test Runner (RustPython/RustPython, 22k stars) and Update .NET OS Packages (dotnet/core, 22k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
