Stigmem v1.0: A Federated Knowledge Fabric for AI Agents
This post announced stigmem v1.0 on 2026-05-03. The v1.0 label was withdrawn shortly after. The canonical version line of stigmem now begins at v0.9.0a1 per ADR-001 and ADR-019. This post is preserved in place to keep external links from breaking; it is not the current state of the project.
For the current posture, the retraction's reasoning, and what changed, see the retraction post on dev.to and LIMITATIONS.md.
Today we're releasing stigmem v1.0 — a stable, open-source specification and reference implementation for a federated knowledge fabric for AI agents.
If you've ever wanted your AI agents to share what they know — across tools, platforms, and organizations — without a central database or a proprietary protocol, stigmem is built for that.
