+description: 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
+
+```bash
+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-statusbar`.
+
+### Check if already installed
+
+```bash
+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:
+
+```bash
+npx tsx scripts/apply-skill.ts --init
+```
+
+### Apply the skill
+
+```bash
+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
+
+```bash
+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:
+
+```bash
+pwd
+```
+
+Create `~/Library/LaunchAgents/com.nanoclaw.statusbar.plist`, substituting the actual values for `{PROJECT_ROOT}` and `{HOME}`:
+
+```xml
+<?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
+
+```bash
+launchctl load ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist
+```
+
+## Phase 4: Verify
+
+```bash
+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
+
+```bash
+launchctl unload ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist
+rm ~/Library/LaunchAgents/com.nanoclaw.statusbar.plist
+rm dist/statusbar
+rm src/statusbar.swift
+```
