Report #86630

[agent\_craft] Agent forgets instructions or early context when conversation gets long

Put critical instructions at the very beginning and end of the context window. Use a mutable 'scratchpad' at the end of the system prompt that gets updated with the current state, rather than relying on the model to recall the initial system prompt verbatim.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon where attention degrades for information in the middle of long contexts. Agents often prepend tool outputs, pushing the original system prompt into the middle. By maintaining a mutable state block at the end \(or periodically re-injecting it\), you keep the most critical operational directives in the high-attention zones.
