Evaluate Agent Outputs With Full Visibility Into the Memory That Drove Them

Agent eval frameworks score outputs without knowing which memory the agent retrieved. A bad output might mean a bad model, a bad prompt, or bad memory — but eval can't tell. MemoryLake links every output to the memory used, so evaluation actually identifies root causes.

The problem: agent evaluation without memory context is blind

The eval framework flagged 12% of outputs as low quality. You don't know if the model failed, the prompt failed, or the retrieved memory failed. Without memory context per evaluation, fixing the right thing is guesswork.

How it works for memory-aware eval

  1. Connect — Wire MemoryLake into your eval pipeline.
  2. Structure — Each generated output records the memory used.
  3. Reuse — Eval analysis shows memory-retrieval failures separately from generation failures.

Who this is for

Engineering teams running agent evaluation pipelines who need to attribute failures correctly to fix the right thing — and where current eval treats memory as a black box.
