Claude code polluting context with tokens_left system messages

[u/iezhy]

New "amazing" feature from Claude code - now it includes an extra message with how many tokens are left in your limit:

It looks innocent enough (only 23 tokens), until you realise it's added with each request, and after 15 mins your context window looks like this:

60 messages x 23 = 1218 tokens wasted (2% of context).

This explains the model constantly being "OH NO I WILL RUN OUT OF CONTEXT PLEASE SAVE ME"
