Kage
Kage is a git-native verification layer for coding agent memory that checks every claim against your code to prevent hallucinations and stale facts.

What is Kage?
Kage is an open-source tool that provides verified memory for AI coding agents. It stores agent memories as plain Markdown files in your git repository and continuously verifies each memory against the actual codebase. Memories with hallucinated citations or stale references are rejected on write or withheld from recall, ensuring agents act only on trustworthy information.
