Neural cheat sheets are a way to train summarizers against downstream utility, not summary aesthetics: optimize the notes for QA / agent performance, keep them token-efficient, and preserve the auditability you lose with latent KV-style memory.
We used RL to train models that create curated context from long documents for downstream use by agents. The models sometimes learn to invent their own abbreviations and shorthand. Optimizing with RL for downstream use produces very different artifacts from ordinary summaries: shorter, denser, creatively concise. We call these neural cheat-sheets.
