YouTrack App Builder

Required Environment

Verify these requirements once near the start of the session before using this skill for YouTrack app work.

Requirement	How to verify
Node.js `>= 20.18.0`	Run `node --version`. Node is required because both scaffolding and app management run through Node-based CLIs and npm scripts.
npm	Run `npm --version`. Use the version bundled with Node.js `>= 24`, unless the app project declares a stricter version.
npx	Run `npx --version`. Use the version bundled with npm, unless the app project declares a stricter version.
`create-youtrack-app` CLI	Run `npx @jetbrains/create-youtrack-app@latest --help`. If it cannot run, read references/cli-setup.md.
`youtrack-app` CLI	Run `youtrack-app --help`. If missing, read references/cli-setup.md. Commands that contact YouTrack also require a target host (`YOUTRACK_HOST`) and token (`YOUTRACK_TOKEN`; `YOUTRACK_API_TOKEN` is also supported). If token variables are not in environment then read the article on how to obtain the token and instruct the user: Manage Permanent Tokens. Never print token values.

If required tooling is missing and cannot be installed in the current environment, ask the user before continuing with a reduced local-only workflow.
