FlowDeck provides an official Claude Code plugin (preferred because it enforces FlowDeck usage and blocks Apple CLI tools). If you can’t use plugins, you can add the FlowDeck skill directly.

Option 1 (Preferred): Install the Plugin

/plugin marketplace add flowdeck-studio/flowdeck-plugin
/plugin install flowdeck@flowdeck-plugins/flowdeck
Restart Claude Code after installing the plugin.

What It Does

Once installed, Claude Code will automatically:
  1. Use flowdeck commands instead of xcodebuild, xcrun simctl, etc.
  2. Follow the FlowDeck debug loop (run app, attach logs, capture screenshots)
  3. Block attempts to use Apple CLI tools directly

What the Skill Does

If you add the FlowDeck skill instead of the plugin, it teaches the agent to use FlowDeck for iOS/macOS build, run, test, and debug workflows instead of Apple CLI tools. It also standardizes project discovery and simulator management so the agent can operate with fewer retries.
The skill does not prevent the agent from sidetracking to xcodebuild or simctl. The plugin enforces that behavior.

Option 2: Add the Skill (No Plugin)

mkdir -p .claude/skills/flowdeck
curl -sSL https://raw.githubusercontent.com/flowdeck-studio/flowdeck-plugin/main/skills/flowdeck/SKILL.md -o .claude/skills/flowdeck/SKILL.md

System Skill (Applies to All Projects)

mkdir -p ~/.claude/skills/flowdeck
curl -sSL https://raw.githubusercontent.com/flowdeck-studio/flowdeck-plugin/main/skills/flowdeck/SKILL.md -o ~/.claude/skills/flowdeck/SKILL.md
AI agents should use the context -> init workflow for reliable builds:
# 1. Discover project structure
flowdeck context --json

# 2. Initialize with discovered settings
flowdeck init -w MyApp.xcworkspace -s MyApp -S "iPhone 16"

# 3. Run commands without parameters
flowdeck build   # Uses saved settings
flowdeck run     # Uses saved settings
flowdeck test    # Uses saved settings

Example Prompts

Just ask Claude Code to work with your iOS/macOS project:
"Build and run my app on an iPhone 16 simulator"
"Run the unit tests and fix any failures"
"Take a screenshot of the current simulator state"
"Run the app and check logs to understand why the login screen isn't working"

Uninstall

/plugin uninstall flowdeck
