Claude Context
Claude Chat Drift
If your Claude chats are getting long, the quality can start dropping off. Not because Claude is broken, but because of how context windows work.
Back to resourcesEvery Claude conversation has a limit to how much it can hold in its memory at once.
When you understand that, long-chat drift starts to make a lot more sense.
Context Windows
A context window is the amount of information Claude can actively work with at one time.
That includes your messages, Claude's replies, files, instructions and the details that have built up throughout the conversation.
The longer the conversation gets, the more Claude has to carry.
The Whiteboard
Think of it like a whiteboard.
At the start of a chat, the whiteboard is clean and Claude is working with everything clearly in front of it.
The longer the conversation goes, the more the board fills up. And when it is full, older information starts to get fuzzy.
Signs Of Chat Drift
That is when responses get vaguer.
That is when Claude starts to drift from the task.
That is not a bug. That is the context window doing exactly what it is designed to do.
Reset The Chat
Instead of pushing through a degrading chat, reset it.
Before you close the conversation, ask Claude to summarise the work in a way that a fresh Claude can understand.
Then copy the response, open a new chat and paste it in.
You are back to a clean whiteboard with the full picture still intact.
The Chat Reset Prompt
Paste this before you start a fresh chat:
Summarise everything we've covered: what we worked on, what's been decided, what worked, what the next step is. Write it so that a fresh Claude with no prior context can pick up exactly where we left off.
Final Thought
I use this constantly now.
When a chat starts drifting, do not keep forcing it. Preserve the context, start fresh and keep moving.
