## What it does

The skill walks your system and reports what is already there: Node.js 18 or newer, jq for parsing Claude output, GitHub CLI for GitHub integration. Anything missing comes with an install command for macOS or Linux, and it waits for your confirmation before running it. It asks which package manager you prefer — npm, pnpm, bun or yarn — and stores the answer for later skills.

Then it installs `cyrus-ai` with that manager and creates `~/.cyrus`. If `~/.cyrus/.env` already exists, the skill notes it and keeps the current values. One rule is baked in: never touch `.env` or any file under `~/.cyrus/` with `Read`, `Edit` or `Write` — only `Bash` with `grep` and `printf >>`, so secrets stay out of the conversation context. Worth remembering if you plan to fork the skill.

\`agent-browser` gets its own check, and only when you picked Linear, GitHub or Slack as an integration surface. Without it you go through manual setup steps, but nothing blocks. At the end you get a summary: what was found, what was installed, what is still missing.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-prerequisites -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cyrus-setup-prerequisites/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cyrus-setup-prerequisites/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-prerequisites -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cyrus-setup-prerequisites/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-prerequisites -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cyrus-setup-prerequisites/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cyrusagents/cyrus cyrus-setup-prerequisites
```

2. **Manually: put the files in place**
- File: `.github/skills/cyrus-setup-prerequisites/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-prerequisites -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cyrusagents/cyrus --path skills/cyrus-setup-prerequisites
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cyrus-setup-prerequisites/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup-prerequisites -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/cyrusagents/cyrus/tree/HEAD/skills/cyrus-setup-prerequisites/SKILL.md

## When to use it
- check Node.js, jq and gh versions before installing Cyrus
- install cyrus-ai through npm, pnpm, bun or yarn
- create ~/.cyrus without overwriting an existing .env
- find out whether agent-browser is available for automated integration setup
- get install commands for missing dependencies on macOS and Linux

## Example prompts
- check the Cyrus prerequisites and install cyrus-ai
- which package manager should I use for Cyrus?
- is agent-browser installed on this machine?

name: cyrus-setup-prerequisites
description: Check and install prerequisites for Cyrus — Node.js, jq, gh CLI, and the cyrus-ai npm package.

**CRITICAL: Never use `Read`, `Edit`, or `Write` tools on `~/.cyrus/.env` or any file inside `~/.cyrus/`. Use only `Bash` commands (`grep`, `printf >>`, etc.) to interact with env files — secrets must never be read into the conversation context.**

# Setup Prerequisites

Checks system prerequisites and installs `cyrus-ai`.

## Step 1: Detect Package Manager

If the user hasn't already specified their preferred package manager, ask:

> **Which package manager do you prefer?** npm, pnpm, bun, or yarn?

Store the answer for use in this and subsequent skills.

## Step 2: Check System Dependencies

Run the following checks and report results:

```bash
# Node.js >= 18
node --version

# jq (required for Claude Code parsing)
jq --version

# GitHub CLI (required for GitHub integration)
gh --version
```

For each missing dependency, provide the install command:

| Dependency | macOS | Linux/Ubuntu |
|-----------|-------|--------------|
| Node.js | `brew install node` | `curl -fsSL https://deb.nodesource.com/setup_22.x \| sudo -E bash - && sudo apt install -y nodejs` |
| jq | `brew install jq` | `sudo apt install -y jq` |
| gh | `brew install gh` | See https://github.com/cli/cli/blob/trunk/docs/install_linux.md |

If all dependencies are present, print a checkmark for each and continue.

If any are missing, offer to install them (detect OS via `uname`). Wait for user confirmation before installing.

## Step 3: Check for agent-browser (Optional)

If the user selected any integration surface (Linear, GitHub, Slack), check for `agent-browser`:

```bash
which agent-browser
```

**If installed**, ensure it's up to date:

```bash
npm update -g agent-browser
```

**If not found**, inform the user:

> `agent-browser` is optional but enables automated app creation for Linear/GitHub/Slack. Without it, you'll be guided through manual setup steps instead.
>
> Install with: `npm install -g agent-browser`

Do NOT block on this — it's optional. Note whether it's available for downstream skills.

## Step 4: Install cyrus-ai

Check if already installed:

```bash
which cyrus
```

If not found, install using the user's preferred package manager:

```bash
# npm
npm install -g cyrus-ai

# pnpm
pnpm install -g cyrus-ai

# bun
bun install -g cyrus-ai

# yarn
yarn global add cyrus-ai
```

Verify installation:

```bash
cyrus --version
```

## Step 5: Ensure ~/.cyrus directory exists

```bash
````
