Run One Task Per Conversation to Keep Context Clean and Rate Limits High
Letting a single Claude Code session sprawl across hundreds of messages feels productive but actually works against you. Your context window fills with noise from earlier tasks, responses become less consistent, and your rate limits take a bigger hit than they need to.
The fix is a habit, not a command: one task, one conversation.
When you finish a task, start fresh.
# Finish task one, exit, open a new session
claude
# ... complete task one ...
exit
claude
# clean context, consistent output — task two starts fresh
You get three concrete wins from this discipline:
- Context stays focused on the current problem so Claude doesn't get pulled in old directions
- Output quality stays consistent instead of drifting as the thread grows longer
- Rate limits stretch further because each session does one focused job
The model doesn't get worse over long threads. The context window just gets noisier, and noise is expensive.
One task per conversation is the simplest habit you can build to keep Claude Code performing at its best.

When Claude starts referencing files you've since deleted, remembering old code you've already changed, or getting confused by contradictory instructions from a long session — type /clear to wipe the slate clean. Unlike /compact which preserves context, /clear gives you a true fresh start without restarting the CLI.
Not every task needs deep reasoning. Type /fast to switch Claude Code into fast mode — same model, faster output — for quick edits, simple questions, and routine changes. Toggle it off when you need Claude to think harder on complex problems.
Long sessions eat through your context window as conversation history piles up. Type /compact to summarize the conversation so far and reclaim space — keeping Claude's understanding of what you're working on while freeing up room for more work.
