Report #63872

[frontier] Context window exhaustion when agents process large tool outputs \(logs, files, API responses\)

Treat large tool outputs as embedding streams rather than raw text; chunk and embed the output, then retrieve relevant segments via semantic search within the agent's context window rather than inserting full dumps.

Journey Context:
Agents calling tools like 'read\_file' or 'search\_logs' receive massive text dumps that quickly fill context windows. Naive truncation loses critical details. The robust pattern is 'embedding-based tool output management': large tool outputs are chunked, embedded, and stored in a temporary vector store accessible only to the current agent session. The agent then performs RAG-style retrieval against these embeddings to pull only relevant chunks into its active context when reasoning about the tool output. This treats tool outputs like external knowledge bases rather than inline text, preserving context window for reasoning.
