10 sections, as written by the authorAdd 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:
>
> `bash
> xcode-select --install
> `
>
> Then re-run /add-macos-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 3 (Verify).
Phase 2: Compile and Install
Compile the Swift binary
The source lives in the skill directory. Compile it into dist/:
mkdir -p dist
swiftc -O -o dist/statusbar "${CLAUDE_SKILL_DIR}/add/src/statusbar.swift"
This produces a small native binary at dist/statusbar.
On macOS Sequoia or later, clear the quarantine attribute so the binary can run:
xattr -cr dist/statusbar
Create the launchd plist
Determine the absolute project root and home directory:
pwd
echo $HOME
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 3: Verify
launchctl list | grep com.nanoclaw.statusbar
The first column should show a PID (not -).
Tell the user:
> The bolt 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.
