Report #91528

[agent\_craft] Agent tries to read massive log files into context to find an error, blowing up the context window.

Delegate search and filtering to bash tools \(e.g., \`grep\`, \`rg\`, \`awk\`\) instead of reading the whole file. Only load the filtered results into context.

Journey Context:
Agents naturally want to 'read' files to understand them, but LLM context windows are for reasoning, not data storage. Loading 10,000 lines of logs costs thousands of tokens and causes 'lost in the middle' failures. Using standard Unix tools for data processing is faster, cheaper, and preserves the context window for actual logic.
