doughnut: Skill for Claude Code

.agents/skills/cloud-vm-setup/SKILL.md

cloud-vm-setup is a skill for Claude Code, Codex from nerds-odd-e/doughnut. It costs 64 tokens per session (828 once invoked), scanned A, original, MIT.

A setup guide for running the Donut development environment on a cloud computer without Nix. Nix is a tool that normally installs and manages a project's development dependencies.

In plain words
What is it for?
Use it to prepare a Cloud VM for frontend tests, backend tests, end-to-end tests, linting, or formatting.
Why use it?
It provides the required tools, services, ports, and test databases when Nix cannot be used on the cloud computer.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is nerds-odd-e/doughnut's own configuration. It tells Claude Code and Codex how to work on doughnut 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 doughnut configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./backend/gradlew -p backend migrateTestDB -Dspring.profiles.active=test.

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 A, and why

cloud-vm-setup scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Purpose: Cloud-agent development and testing when nix develop is unavailable.

Output: Environment ready for tests + summary ending with ## CLOUD VM READY.

Pre-configured: Node.js v24.16.0, pnpm 11.3.0 — no nix needed.

Ports:

Service Port
Spring Boot 9081
Local LB 5173
Vite dev 5174
MySQL 3309
Redis 6380

CI=1 is exported by the setup script (CLI PTY tests use pipe fallback, matching GitHub Actions).

source /workspace/scripts/cloud_agent_setup.sh

Installs: Java 25, MySQL 8.4 (port 3309), Redis (port 6380), xvfb, and initializes test databases.

Single file: pnpm -C frontend test tests/path/to/TestFile.spec.ts (no -- before the path).

<success_criteria>

  • Setup script run when backend/E2E needed
  • Commands run without nix prefix
  • Correct ports and healthcheck commands available
  • Final output includes ## CLOUD VM READY </success_criteria>

Common commands:

Task Command
Frontend tests pnpm frontend:test
Backend tests pnpm backend:verify
Linting pnpm lint:all
Formatting pnpm format:all
## CLOUD VM READY

<out_of_scope>

  • Do not use CURSOR_DEV=true nix develop -c on Cloud VM.
  • Do not assume local Nix shell ports or paths (/Users/... vs /workspace/...). </out_of_scope>

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.
