## What it does

The skill orchestrates an end-to-end Cyrus installation. It walks through prerequisite checks for package managers like npm or pnpm, connects Claude authentication, and configures webhook endpoints. Next, it configures issue trackers and chat platforms such as Linear, GitHub, and Slack.

Browser automation handles UI forms to save manual clicking. The skill prefers `claude-in-chrome` MCP tools because they reuse existing login sessions. If those tools are missing, it falls back to the Playwright-based `agent-browser` binary with an isolated Chrome profile, or provides manual guided instructions.

Direct reads and edits of `~/.cyrus/.env` are strictly blocked. This precaution keeps API tokens and secrets out of the conversation context. All updates happen through visible `Bash` commands that require explicit user approval.

## Requirements
- Works with: GitHub, Linear, Slack

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cyrusagents/cyrus --skill cyrus-setup -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/SKILL.md

## When to use it
- set up Claude Code as a background task runner
- configure integrations for Linear, Slack, GitLab, and GitHub
- automate web credential entry using Playwright or claude-in-chrome
- store API credentials in ~/.cyrus/.env without exposing them in context

## Example prompts
- Run /cyrus-setup to configure Cyrus for Linear and GitHub
- Use cyrus-setup to guide me through the Slack integration

# Cyrus Setup

One-command setup for self-hosted Cyrus. This orchestrator walks you through everything needed to run Claude Code as a background agent from Linear, Slack, and GitHub.

## CRITICAL Rules

### Never Read or Write ~/.cyrus/.env Directly

**FORBIDDEN:** Do NOT use `Read`, `Edit`, or `Write` tools on `~/.cyrus/.env` or any file inside `~/.cyrus/`. This file contains secrets (API keys, tokens, signing secrets). All interaction with this file MUST go through `Bash` commands (`grep`, `printf >> ...`, etc.) which the user can see and approve. Never read its contents into the conversation context.

### Browser Automation

The goal of browser automation in this skill is to **reduce sign-in and setup fatigue** — the agent navigates web UIs, fills forms, and scrapes credentials so the user doesn't have to do it all manually.

**Three modes, in order of preference:**

1. **`claude-in-chrome`** (preferred when available) — if the user is running Claude Code and has the `claude-in-chrome` MCP extension connected, use it. This has the huge advantage of using the user's existing Chrome with all their signed-in sessions (Linear, Slack, GitHub). Check availability by seeing if `mcp__claude-in-chrome__*` tools exist.
2. **`agent-browser` CLI** — a standalone Playwright-based binary invoked via `Bash`. Requires launching a **fresh Chrome profile** with remote debugging enabled (the user will need to sign in to services in that profile). Check with `which agent-browser`.
3. **Manual guided flow** — the user follows the agent's step-by-step instructions and does the clicks themselves. Always available as Path B in each sub-skill.

**Determining which mode to use:**

1. First, check if `claude-in-chrome` MCP tools are available in the current session. If yes, use those — no setup needed.
2. If not, check `which agent-browser`. If installed, launch a fresh Chrome profile (see below).
3. If neither is available, ask the user: install `agent-browser`, or follow manual instructions?

**`agent-browser` setup — fresh Chrome profile:**

`agent-browser` needs a Chrome instance with remote debugging enabled. Launch one with an isolated profile:

```bash
# Find an open port
for port in $(seq 9222 9322); do
  if ! lsof -i :"$port" > /dev/null 2>&1; then
    echo "Open port found: $port"
    break
  fi
done
```

```bash
# Create a fresh profile directory
mkdir -p ~/.cyrus/chrome-profile
```

```bash
# Launch Chrome with remote debugging (runs in background)
# macOS:
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --remote-debugging-port=<port> \
  --user-data-dir="$HOME/.cyrus/chrome-profile" &

# Linux:
google-chrome --remote-debugging-port=<port> \
  --user-data-dir="$HOME/.cyrus/chrome-profile" &
```

```bash
````
