[synthesis] Agent instruction-following degrades silently in long sessions without explicit context overflow errors

Implement a dynamic context budget for tool error outputs; compress or summarize non-fatal errors before re-inserting them into the context window, and monitor the ratio of error-tokens to system-prompt-tokens.

Journey Context:
Teams monitor for hard context limit errors \(HTTP 400\) but miss the gradual displacement of the system prompt. When an agent encounters non-fatal API errors \(e.g., 429s, partial data\), the lengthy stack traces or retry logs consume context tokens. The model still responds, but its adherence to the original system instructions degrades because the attention mechanism is dominated by recent, noisy error text. Standard token counting doesn't reveal this; you must track the semantic density of the context window.
