A new tool called Hc addresses a common pain point for engineers: losing shell command history when servers are ephemeral. Instead of relying on local `.bash_history` files, it creates a centralized, permanent repository for every keystroke, preserving complex one-liners long after the original server is destroyed.

The tool works by capturing terminal sessions at the connection gateway level, requiring no agents on target machines. It reconstructs activity from raw recording files, providing a high-fidelity log of all commands and outputs. This passive approach builds a personal knowledge base without touching remote host configurations.

Hc features a multi-tenant architecture, automatically categorizing history by project or organization tags defined at the gateway. This isolates work for different clients, preventing noise when searching for specific solutions. The search interface stays in the command line, turning your entire history into a grep-friendly database.
