What it does
Onboard is an agent skill from justxor/claude-code-pro-course. Проводит онбординг нового разработчика в проект - обзор архитектуры, запуск, ключевые потоки и первая задача. Используй, когда просят объяснить проект, ввести в курс дела или помочь новичку.
Its SKILL.md is about 270 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 Agent Workflows. The repository describes itself as: Claude Code PRO — полный курс и гайд на русском: CLAUDE.md, settings, skills, subagents, hooks, MCP, плагины, CI. 8 лабораторных, библиотека промптов и готовый starter-kit. Здесь…. The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/onboard”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash(git log:*), Bash(ls:*)
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Одним абзацем: что это за продукт и для кого.
- Карта: дерево ключевых директорий (до 15 строк) с пояснением каждой.
- Запуск: установка, dev, тесты, один тест — проверь по CLAUDE.md/package.json/Makefile.
- Главные потоки: 2–3 ключевых сценария (например, «запрос → ответ», «фоновая задача») — путь по файлам.
- Грабли: неочевидные места, соглашения, то, что легко сломать.
- Кто что знает: по git log — самые активные авторы по областям (только имена из истории).
- Первая задача: предложи 3 небольшие задачи для знакомства (good first issue), от простой к сложной.
What it can do on your machine
Read from SKILL.md and the folder at commit 685e438. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBash(git log:*)Bash(ls:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Onboard loads about 267 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 109 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 passed
The automated check found no risky patterns in SKILL.md.
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.

Can I use Onboard 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 justxor/claude-code-pro-course --skill onboard -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/onboard, .gemini/skills/onboard, .github/skills/onboard and .opencode/skills/onboard in your project.
What does Onboard need to run?
