Author open-sources KYB v0.3.3 cross-session memory store
Understand this story
Alexander Panasenko has open-sourced KYB v0.3.3, which uses Git-backed shared storage to save operation records with versioning and lifecycle states (active, archived, retracted) for Claude Code, OpenAI Codex, and Google Antigravity, with the aim of preventing outdated notes from misleading agents into retreading rejected paths. This version was released on October 27, 2026 (commit 06f63b5). Panasenko said he did not run a controlled test comparing agents with and without KYB, so the time lost to outdated notes is only his personal recollection, not a measured saving after adoption. In v0.3.3, the export command is available in the CLI and over HTTP (GET /export), but is not an MCP tool; automatic injection of kyb context was only a proposal at the time, and this version's server does not provide it.

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.
