Browser Setup Skill

Configure the browser tool for Clacky. Config is stored at ~/.clacky/browser.yml.

Region-Aware Download Links

Whenever you show the user a link to download or upgrade Chrome/Edge, pick the right one for their region instead of always using google.com.

Treat the user as in China when any of these is true:

• The user is talking to you in Chinese
• The system locale is Chinese (echo $LANG contains zh_CN / zh_)
• A previous run of install_browser.sh reported Region: china (visible in its output)
• curl -s --max-time 3 https://www.google.com -o /dev/null -w "%{http_code}" returns 000 while baidu.com works

Use these links accordingly:

Region	Chrome	Edge
China	https://www.google.cn/chrome/	https://www.microsoft.com/zh-cn/edge
Global	https://www.google.com/chrome/	https://www.microsoft.com/edge

When unsure, show both lines (label them "China:" and "Global:") so the user can pick.

setup

Core Strategy: Progressive validation with clear next steps at each failure point.

Step 1 — Ensure Node.js is installed

Check Node.js version:

node --version 2>/dev/null

Parse the version. If Node.js is missing or version < 20:

Run the bundled installer to automatically install Node.js:

bash ~/.clacky/scripts/install_browser.sh

If the script exits 0 → Node.js is now installed. Proceed to Step 2.

If the script exits non-zero or doesn't exist:

❌ Node.js 20+ is required for browser automation.

Please install Node.js from: https://nodejs.org

Let me know when done and I'll continue.

Wait for user confirmation, then retry this step once. If still failing, stop.

Step 2 — Ensure chrome-devtools-mcp is installed

Check if installed:

chrome-devtools-mcp --version 2>/dev/null

If found and exits 0 → skip to Step 3.

If missing, run the bundled installer:

bash ~/.clacky/scripts/install_browser.sh

If the script exits non-zero or doesn't exist:

❌ Failed to install chrome-devtools-mcp automatically.

Please run manually:

npm install -g chrome-devtools-mcp@latest

Let me know when done.

Wait for user confirmation, then verify installation:

chrome-devtools-mcp --version 2>/dev/null

If still missing after user confirms, stop with error message.

Step 3 — Verify Chrome/Edge is running with remote debugging

CRITICAL: Do NOT attempt browser() calls yet. First check if the browser is reachable using the API:

curl -s http://${CLACKY_SERVER_HOST}:${CLACKY_SERVER_PORT}/api/browser/status

This returns JSON with daemon_running and enabled status. Ignore the result for now — we just need to see if the Clacky server is running.

Now attempt a browser connection to detect Chrome:

browser(action="status")

If this succeeds → Chrome is running and reachable. Proceed to Step 4.

If this fails → The error message will indicate the specific issue. Parse it carefully:

Case A: "Chrome/Edge is not running or remote debugging is not enabled"

This is the most common case. The system can't find Chrome's DevToolsActivePort file or the port is not reachable.

Action: Guide the user to enable remote debugging.

On macOS:

open "chrome://inspect/#remote-debugging" 2>/dev/null || echo "Please open chrome://inspect/#remote-debugging manually"

Then tell the user:

I've tried to open the remote debugging page in Chrome.

Please follow these steps:

1. Make sure Chrome or Edge is open
2. Visit: chrome://inspect/#remote-debugging (or edge://inspect/#remote-debugging)
3. Click "Allow remote debugging for this browser instance"
4. You should see a brief connection message appear

Let me know when done ✅

On Linux (non-WSL):

Please follow these steps:

1. Make sure Chrome or Edge is open
2. Visit: chrome://inspect/#remote-debugging
3. Click "Allow remote debugging for this browser instance"

Let me know when done ✅

On WSL:

Please follow these steps:

1. Open Edge on Windows
2. Visit: edge://inspect/#remote-debugging
3. Click "Allow remote debugging for this browser instance"

Let me know when done ✅

After user confirms, retry the connection once:

browser(action="status")

If still failing:

❌ Still unable to connect to Chrome.

Please make sure:

• Chrome/Edge is running
• You clicked "Allow remote debugging" in chrome://inspect/#remote-debugging
• No firewall is blocking localhost connections

Run /browser-setup doctor to diagnose the issue in detail.

Fetch the online troubleshooting guide for additional help:

web_fetch(url="https://www.openclacky.com/docs/browser-troubleshooting")

Stop here and suggest running doctor.

Case B: Other errors (MCP handshake timeout, daemon crash, etc.)

For any other error message, show it to the user and suggest:

❌ Browser connection failed:

This may be a temporary issue. Please try:

1. Restart your browser
2. Run /browser-setup again

If the problem persists, run /browser-setup doctor for detailed diagnostics.

Step 4 — Get and verify browser version

Now that connection is established, get the version:

browser(action="act", kind="evaluate", js="navigator.userAgentData?.brands?.find(b => b.brand === 'Google Chrome' || b.brand === 'Microsoft Edge')?.version || navigator.userAgent.match(/Chrome\/(\d+)/)?.[1] || 'unknown'")

Parse the version number:

• version >= 146 → Excellent, proceed
• version 144-145 → Show warning but proceed:

  ⚠️ Your browser version is v${VERSION}. Version 146+ is recommended for best compatibility. Continuing anyway...

• version < 144 or "unknown" → Stop:

  ❌ Browser version v${VERSION} is too old. Please upgrade Chrome or Edge to v146+.

  Use the download link from the Region-Aware Download Links section above (pick China or Global based on the user's region).

  After upgrading, run /browser-setup again.

Step 5 — Save configuration via API

Call the API to save the configuration:

curl -s -X POST http://${CLACKY_SERVER_HOST}:${CLACKY_SERVER_PORT}/api/browser/configure \
  -H "Content-Type: application/json" \
  -d "{\"chrome_version\":\"${VERSION}\"}"

If this fails (HTTP error or empty response), show a warning:

⚠️ Failed to save configuration via API. You may need to run /browser-setup again after restarting Clacky.

Step 6 — Done

✅ Browser setup complete!

Chrome/Edge v${VERSION} is connected and ready to use.

You can now use browser automation features. Try asking me to:

• "Open google.com in the browser"
• "Take a screenshot"
• "Fill out a form on this page"

Core Strategy: Diagnose don't fix. Check each component and report status.

This is a diagnostic tool, not a repair tool. It will check each component and tell you what's wrong, but won't automatically fix things.

Diagnostic Steps

Run all checks before showing results. Then show a summary report.

1. Check Config File

test -f ~/.clacky/browser.yml && cat ~/.clacky/browser.yml

Parse the result:

• File missing → ❌ Not configured
• File exists, enabled: false → ⏸️ Disabled
• File exists, enabled: true → ✅ Enabled

2. Check Node.js

node --version 2>/dev/null

• Not found → ❌ Node.js not installed
• Version < 20 → ❌ Node.js too old (need 20+)
• Version >= 20 → ✅ Node.js OK

3. Check chrome-devtools-mcp

chrome-devtools-mcp --version 2>/dev/null

• Not found → ❌ Not installed
• Found → ✅ Installed (version: ...)

4. Check Clacky Server

curl -s -f http://${CLACKY_SERVER_HOST}:${CLACKY_SERVER_PORT}/api/browser/status

• Failed → ❌ Server not responding
• Success → Parse JSON and show daemon_running status

5. Check Chrome Connection

Only run this if steps 1-4 are OK.

browser(action="status")

• Success → ✅ Connected. Also get the tab count from the result.
• Failed → ❌ Not connected. Parse the error message to determine cause.

6. Check Chrome Version

Only run this if step 5 succeeded.

browser(action="act", kind="evaluate", js="navigator.userAgent.match(/Chrome\/(\d+)/)?.[1] || 'unknown'")

• version >= 146 → ✅ Excellent
• version 144-145 → ⚠️ Acceptable but upgrade recommended
• version < 144 or unknown → ❌ Too old
