Report #1508

[agent\_craft] Agent forgets system instructions or tool schemas in long sessions

Move critical operational instructions and tool schemas to the END of the prompt, or periodically re-inject them after context compaction, rather than relying solely on the initial system prompt.

Journey Context:
As conversation history grows, the initial system prompt gets pushed into the 'middle' of the context window. LLMs exhibit a 'lost in the middle' attention pattern where they heavily weight the beginning and end of the context, ignoring the middle. Keeping the most critical operational constraints at the very end \(or re-appending them\) ensures they remain in the high-attention zone, preventing tool misuse or instruction forgetting.
