After an agent has analyzed a payments service, the team wants to compare two refactoring approaches: extracting a ledger module versus introducing an event queue. Tried one after the other in the same session, the second attempt keeps referencing changes and conclusions from the first. What is the best approach?

Answer: B — Use fork_session from the analyzed baseline to create two independent branches, one for each approach

fork_session creates independent branches from a shared analysis baseline, so each approach starts from the same understanding without inheriting the other's work. Reverting files (a) leaves the first attempt in the conversation, fresh sessions (c) pay for the analysis twice, and asking the agent to disregard context (d) doesn't remove it.
