[synthesis] Agent reasoning degrades after reading large boilerplate files

Implement token-budget-aware tool outputs; always summarize, extract specific lines, or use search/grep rather than catting entire files into the context window.

Journey Context:
Agents often read entire generated files \(e.g., lockfiles, bundled JS, large CSVs\) to find a single value. The LLM context fills with low-signal data, causing the model to 'forget' instructions or hallucinate due to attention dilution. Developers assume more context is better, but LLMs suffer from the 'lost in the middle' phenomenon where crucial reasoning is overshadowed by boilerplate. Extracting specific lines preserves the context window for high-signal reasoning and accurate instruction following.
