Security tools

102 tools in curated categories (Network, Web testing, OSINT, Linux, Forensics, SOC, Cloud, Containers, AI Security). Each tool opens an end-to-end manual: what it is, when to use it, Kali Linux notes, help/man style commands, installation, examples, and important limits. Authorized use only.

Command syntax lives in Commands (merged with this toolkit by category).
