Activates for any bug bounty, penetration testing, or vulnerability research request. Triggers on: "start recon on [target]", "check for IDOR/SSRF/XSS on [endpoint]", "map attack surface for [domain]", "write a HackerOne/Bugcrowd report", "help me find vulns in this API", "create a PoC for this vulnerability", "enumerate subdomains", "scan for open ports", "chain these vulnerabilities", or any request involving ethical hacking, web/API security testing, red-teaming, or responsible disclosure.
