[synthesis] Agent follows a chain of references \(imports, call sites, definitions\) deeper and deeper, losing sight of the original task

Set a depth budget for reference chasing: maximum N hops from the original task context \(start with N=4\). At each hop, explicitly re-state the original task and how the current investigation relates to it in one sentence. If you cannot articulate the connection, stop and return to the original context. Reference chasing beyond the depth budget requires explicit justification: 'I am at hop 5 because the root cause of the original bug traces through this chain.'

Journey Context:
An agent tasked with 'fix the login bug' reads the login function, which calls validateToken, which imports from cryptoUtils, which has a dependency on keyManager, which reads from config. Five hops later, the agent is debugging the config system and has forgotten it was supposed to fix a login bug. Each hop feels productive — the agent is 'understanding the codebase' — but it is actually context-drifting. The depth budget is a hard constraint that prevents this. The tradeoff is that sometimes the root cause IS five hops away. The solution is not to ban deep investigation but to force the agent to maintain a tether to the original task. The one-sentence articulation test is the key: if you cannot concisely explain why you are reading this file in relation to your task, you have drifted. This is the agent equivalent of the XY problem in human debugging — you started asking about X but got lost investigating Y.
