TheoMemory vs Mem0 — honest tradeoffs
Mem0 is a category leader in agent memory. TheoMemory is the memory layer of the Theo ecosystem. Honest comparison of what each one does best.

Memory and Context: the unidirectional rule that holds it together
Memory → Context, never the reverse. Four design rules (D1–D4) from cross-validating 12 production implementations — and the failure mode each one prevents.

Five stages of gradual context compaction
Compacting the whole context at 50% is wasteful. Waiting until 99% triggers Context Rot. The middle path is a five-stage pipeline that stops at the first stage that resolves the pressure.

Progressive disclosure: how to give an agent 200 tools without breaking it
Frontloading every tool schema works up to 10 tools. After that, accuracy collapses. Progressive disclosure inverts the default — Anthropic reports 134K → 8.7K tokens and 49% → 74% accuracy on Opus 4.

The five components of an agent memory system
A memory layer is not just a vector store. The taxonomy that emerges from production implementations and the CoALA paper is five components — Store, Write, Recall, Dream, Auxiliary LLM — and they cooperate in a continuous loop.
