playwright-skill

This file functions as an automation 'universal executor' that can run attacker-supplied JavaScript (via CLI args, file input, or stdin) by writing it to disk and requiring it. It also performs runtime npm/npx installation if Playwright is missing and includes environment-derived extra headers in the auto-generated Playwright wrapper path. No explicit malicious payload (e.g., backdoor/exfil endpoint) is present in the shown code, but its design enables arbitrary code execution and increases supply-chain/network exposure. Overall: high capability/abuse potential, not clear built-in malware from this snippet alone.
