[synthesis] Agent edits the wrong file after search tools return massive truncated results that exclude the most relevant matches

Enforce strict depth and result limits on search tools \(e.g., grep -r -n --include=\*.py \| head -n 30, find -maxdepth 3\), and require agents to narrow the search scope iteratively rather than broadly.

Journey Context:
Agents often use grep or find to locate code. Searching for a common term across a large repo returns thousands of lines. The tool truncates the output, cutting off the actual target file which might be deep in the directory tree. The agent then myopically focuses on the top results \(often tests or configs\), editing the wrong file. People assume broad searches are efficient. The tradeoff is missing a deeply nested file vs. maintaining a manageable observation space. The right call is iterative narrowing: forcing the agent to search within specific directories first prevents context truncation and ensures the agent's attention is on relevant code.
