add-statusbar	Add a macOS menu bar status indicator for NanoClaw. Shows a ⚡ icon with a green/red dot indicating whether NanoClaw is running, with Start, Stop, and Restart controls. macOS only.

Add macOS Menu Bar Status Indicator

Adds a persistent menu bar icon that shows NanoClaw's running status and lets the user start, stop, or restart the service — similar to how Docker Desktop appears in the menu bar.

macOS only. Requires Xcode Command Line Tools (swiftc).

Phase 1: Pre-flight

Check platform

If not on macOS, stop and tell the user:

This skill is macOS only. The menu bar status indicator uses AppKit and requires swiftc (Xcode Command Line Tools).

Check for swiftc

which swiftc

If not found, tell the user:

Xcode Command Line Tools are required. Install them by running:

xcode-select --install

Then re-run /add-statusbar.

Check if already installed

launchctl list | grep com.nanoclaw.statusbar

If it returns a PID (not -), tell the user it's already installed and skip to Phase 4 (Verify).

Phase 2: Apply Code Changes

Initialize skills system (if needed)

If .nanoclaw/ directory doesn't exist yet:

npx tsx scripts/apply-skill.ts --init

Apply the skill

npx tsx scripts/apply-skill.ts .claude/skills/add-statusbar

This copies src/statusbar.swift into the project and records the application in .nanoclaw/state.yaml.

Phase 3: Compile and Install

Compile the Swift binary

swiftc -O -o dist/statusbar src/statusbar.swift

This produces a small (~55KB) native binary at dist/statusbar.

Create the launchd plist

Determine the absolute project root:

pwd

Create ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist, substituting the actual values for {PROJECT_ROOT} and {HOME}:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.nanoclaw.statusbar</string>
    <key>ProgramArguments</key>
    <array>
        <string>{PROJECT_ROOT}/dist/statusbar</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
    <key>EnvironmentVariables</key>
    <dict>
        <key>HOME</key>
        <string>{HOME}</string>
    </dict>
    <key>StandardOutPath</key>
    <string>{PROJECT_ROOT}/logs/statusbar.log</string>
    <key>StandardErrorPath</key>
    <string>{PROJECT_ROOT}/logs/statusbar.error.log</string>
</dict>
</plist>

Load the service

launchctl load ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist

Phase 4: Verify

launchctl list | grep com.nanoclaw.statusbar

The first column should show a PID (not -).

Tell the user:

The ⚡ icon should now appear in your macOS menu bar. Click it to see NanoClaw's status and control the service.

• Green dot — NanoClaw is running
• Red dot — NanoClaw is stopped

Use Restart after making code changes, and View Logs to open the log file directly.

Removal

launchctl unload ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist
rm ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist
rm dist/statusbar
rm src/statusbar.swift
