Three steps help manage it: spot the symptoms (slow responses, lower quality outputs), check usage with the /context command, then fix it using either /clear to start fresh or /compact to compress the context while preserving valuable session history. The rule of thumb: don't argue with a degraded session, reset it. ## Full article daily.dev links to this article rather than hosting it.
