Active·★ 17·NOASSERTION·Updated 2026-10-17

Lockkeeper is a local skill router and prompt-injection firewall designed for AI coding agents. It efficiently routes tasks to a small, relevant set of skills, reducing context window size and enhancing tool choices, while also scanning skills and tool calls for security threats.
