Port Scanner

The Port Scanner skill performs fast, configurable TCP and UDP port scanning on IP addresses or hostnames you specify, with service detection and version fingerprinting powered by an Nmap integration. Scan common ports only, a custom range, or all 65535 ports depending on depth required. For each open port the skill identifies the running service (SSH, HTTP, FTP, MySQL, etc.) and attempts to determine the software version, which is cross-referenced against a CVE database to flag known vulnerabilities associated with that version. Results are displayed as a clean table with port, state, service, version, and risk level. Scan timing presets (fast, normal, thorough, stealthy) balance speed against detection risk. Reverse DNS resolution maps IPs to hostnames automatically. Output can be saved as a structured JSON report for integration with ticketing or compliance systems. The skill operates only on targets you explicitly authorize with a confirmation prompt. It pairs with the Vulnerability Scanner skill to create a full external reconnaissance and assessment pipeline. Requires Nmap installed on the host system.
