Context management determines what each agent knows. Shared context enables collaboration—all agents see the same task description and objectives. Isolated context prevents information leakage and reduces noise—a specialist doesn't need another specialist's working notes. Context summarization compresses information for handoffs, preserving essentials while reducing tokens. Context pruning removes irrelevant information as orchestrations progress. Good context management balances agents having enough information to work effectively with not being overwhelmed by irrelevant details.
