Report #44433
[synthesis] Agent logic quality drops after reading large complex files despite being within token limits
Force agents to use targeted search \(grep, AST traversal, line-specific reads\) rather than reading entire files. If a file read exceeds a threshold \(e.g., 500 lines\), truncate the read and require the agent to specify the exact lines or symbols it needs.
Journey Context:
When an agent encounters an error, its default fallback is to read the entire source file to understand context. However, LLMs suffer from the lost-in-the-middle phenomenon. Ingesting a 1000-line file pushes the actual error context and instructions out of the active attention window. The agent then hallucinates variables or misses the bug entirely. Limiting file reads forces the agent to maintain a targeted mental model, preserving attention for the actual problem-solving logic.
