Memory & context

Stories

• Chroma Context-1: Training a Self-Editing Search Agent (Chroma Research)

  Chroma research post · Story page

  A search agent trained for answers that live across several documents rather than in one pass.

• Letta Code: A Memory-First Coding Agent (Letta)

  Letta blog · Story page

  A model-agnostic coding agent that researches a codebase to form memories and can rewrite its own system prompt.

• Letta Evals: Evaluating Agents That Learn (Letta)

  Letta blog · Story page

  An open-source framework for testing agents whose behavior changes as they accumulate context.

• EA-Graph: Artifact-Anchored Verification Memory for Coding Agents under Upstream Drift (arXiv)

  arXiv preprint · Story page

  EA-Graph anchors a coding agent's verification memory to the exact artifacts that supported each claim, and tracks evidence strength separately from freshness. When upstream code drifts or disappears, old claims get classified as affected or unprovable instead of quietly surviving as stale prose notes.

• Introducing Mods: Enabling Agents to Self-Improve through Harness-Level Adaptation (Letta)

  Letta blog · Story page

  Mods lets an agent extend and revise the Letta Code harness itself, not only its prompts, memory, or skills. It treats harness behavior as learnable state, building on Letta's versioned context store and self-editing memory tools.

• SafeCommit: Certifying When Memory-Grounded Agents May Safely Act (arXiv)

  arXiv preprint · Story page

  A risk-controlled gate between an agent's reasoning and its side-effectful actions when persistent memory may be stale or corrupted.
