Purpose & Capability
The name/description (browser health check / auto-repair) align with the included script and SKILL.md. The script inspects a local OpenClaw config (~/.openclaw/openclaw.json), probes localhost CDP ports, and offers to start/kill/restart services — all coherent with diagnosing browser/CDP issues.
ℹ
Instruction Scope
Instructions stay focused on browser health: checking status, querying http://127.0.0.1:<port>/json endpoints, and restarting or killing local processes. Two items to note: (1) the SKILL.md example uses exec("openclaw gateway restart") inside Python, which is a coding error (exec executes Python, not shell) — this is a bug, not exfiltration; (2) the post-fix actions include running system commands (taskkill, openclaw gateway restart) which are expected for repair but are privileged actions the user should expect before enabling automatic fixes.
✓
Install Mechanism
There is no install spec (instruction-only plus a single Python script). Nothing is downloaded or written by an installer during skill install.
✓
Credentials
The skill requests no environment variables, no external credentials, and only reads a local configuration file (~/.openclaw/openclaw.json). That local config access is reasonable for a tool that needs to inspect OpenClaw browser settings.
✓
Persistence & Privilege
The skill is not always-enabled and uses the platform defaults for invocation. The only privileged actions are local repair steps (taskkill, restarting gateway) which are gated behind the --fix flag or explicit repair instructions — appropriate for this purpose.
Assessment
This skill appears to do what it says: local diagnostics of the OpenClaw browser/CDP setup. Before installing or running with automatic fixes enabled, consider: (1) The script reads ~/.openclaw/openclaw.json — review that file if you care about what configuration is inspected. (2) If you run the script with --fix or follow SKILL.md repair steps, it may run system commands that kill processes (taskkill) or restart the OpenClaw gateway — these are destructive to local processes and require appropriate privileges. (3) Some repair commands in SKILL.md are Windows-specific (netstat -ano, taskkill) and the find/kill logic may not work on Linux/macOS as-is. (4) The SKILL.md contains a small coding mistake (using exec("openclaw gateway restart") in a Python snippet) — the intent is to run the shell command, but that snippet will not work as shown. Recommendation: run the health check in non-fix/diagnostic mode first to see reported issues, inspect the detected PID/process before allowing automated kills, and ensure the skill is only used on machines where you trust restarting/killing processes is acceptable.

Like a lobster shell, security has layers — review code before you run it.
