AI Agent Has Amnesia. Mine Keeps Receipts

Alexander Panasenko describes KYB (Know Your Business), his open-source Git-backed store that keeps versioned records with lifecycle states (active, archived, retracted) so coding agents across Claude Code, Codex and Antigravity can query current state, history or a time slice separately instead of trusting stale Markdown notes. Pinned to KYB v0.3.3 (commit 06f63b5, October 27, 2026), the piece covers write-time versus event-time limits, deadline reminders, and a small qualitative survey of five internal agents, with no controlled benchmarks.
