Every agent tool stores memory in its own shape, and every week someone builds another one. None of them can read the others. Observability had the same problem until OpenTelemetry gave everyone one data model to share. A tour of today's memory formats, the proposals that already exist, and what a shared spec could look like.
That's four different shapes, and none of them can read the others. A lesson your CI agent learns stays in whatever wrote it. Your editor agent can't read it, and neither can the next tool you try.
Each format is reasonable on its own. Together, they rebuild the same small idea again and again: a note an agent left for its future self, stored at some address, true for a while.
