I'm 21 days into building in public on dev.to. Three different threads I joined this week started in completely different places — one was a Welcome Thread first-comment about agent design, one was an X-driven side conversation about memory and sycophancy, one was a same-day launch post from a solo dev in Accra shipping his own memory API.
All three converged on the same gap. Every agent memory API I touched this week — including the one I build against in my own stack — is missing the same field: a lifecycle state.
The default model
Store → retrieve → delete. That's the entire API surface for most agent memory services. Mem0, Zep, Letta, OpenAI's Assistants memory, the new AgentRAM, the userMemories layer I work with directly. Three verbs, plus search, plus tenancy.
The model handles "this fact exists" beautifully. It handles "remove this fact" beautifully.
