Claude Code updates fork behavior to reduce subagent costs

By PulseAugur Editorial · [1 sources] ·

Claude Code has introduced a new 'fork' subagent type that inherits the conversation and prompt cache, significantly reducing costs by allowing subsequent agents to read from the cache rather than re-processing the entire prompt.
