The Pointer Pattern: Handling Large Data
April 26, 2026 ยท View on GitHub
One of the most significant challenges in building autonomous agents is managing the context window of LLMs.
Large Payloads
When a tool returns a massive amount of data (e.g., >10KB), passing it directly to the LLM can result in truncated responses or loss of focus.
How it Works
The Pointer Pattern solves this issue by:
- Spillover Detection: The framework monitors tool outputs.
- Disk Persistence: Results exceeding a threshold are saved to a session-specific directory on disk.
- Pointers: The LLM receives a lightweight "pointer" (a unique ID and file path) instead of the full payload.
- On-Demand Retrieval: The agent can "read" specific chunks of the data using dedicated tools (e.g.,
read_pointer) only when needed.
