AI agents can drown when tool outputs get too large (AWS Strands context bloat fix)
YouTube ● Covered by 2 sources
AI agents fail when tool outputs are large because the model repeatedly re-reads the full response while generating the next steps. A 214KB tool output can make the agent’s answers get worse even with a larger context window. As a result, developers need fixes that control or trim tool output size rather than relying on bigger context limits.
Why it matters
An AWS developer advocate explains how agents break when tools return big outputs—like large log dumps—because the model keeps re-reading everything. The write-up highlights that a bigger context window doesn’t solve it, and a tool response of 214KB can make answers get worse.
