One long Claude Code thread vs parallel sessions, what's actually better for your workflow and where each one falls apart

# מהמקור

Would be curious about how you interact with Claude Code in reality. Is it one long thread or parallel sessions? Long single thread: Pros: - Claude remembers the whole history of all the decisions - It's cheaper, caches better Cons: - It takes longer, everything is done sequentially one task at a time - More context is gathered, old constraints are forgotten or summarized but hopefully evicted when not needed anymore Parallel sessions or worktrees: Pros: - Faster because independent pieces of work are done at once - Each session has its focus on one particular thing Cons: - Conflicts while joining all the work
