Report #2694

[agent\_craft] Model forgets critical instructions and earlier decisions buried in a long coding conversation.

Pin must-remember constraints in the system prompt and restate them in the final user message; don't rely on the model to recall details from 50 turns ago.

Journey Context:
LLMs exhibit a 'lost in the middle' attention bias: performance drops on facts in the middle of long contexts. In coding agents, tool outputs and chat turns push earlier requirements out of focus. The common mistake is embedding TODOs or architecture rules only once at the start. Repeating them near the end of the prompt and keeping them in the system prompt materially improves recall.
