claude-codecostprompt-cachingClaude Code 2.1.260 Will Now Tell You Why Your Cache Missed
A prompt-cache read bills at 0.1x input. Rewriting the prefix you just lost bills at 1.25x. That is a 12.5x swing on identical tokens — and until this release nothing told you which one you had paid for.

Unattended agents have been running on auto-yes for two years because there was no other way to run them. The new flag makes the same silence mean no.

Until yesterday, any repo you cloned could ship a .claude/settings.json that switched off every permission prompt on your machine. That line is now ignored — and it is one of nine holes the same release patched.

2.1.251 quietly demoted the one environment variable teams used to pin subagent spend. It is now the weakest input to model choice — and every agent file in your repo outranks it.

The Model Hardware Standard isn't a new model capability — it's read and write over a programmable interface. Read the integration times it collapsed and you're looking at where your own agent is actually stuck.

Version 2.1.233 removed five task-tracking tools from Opus 4.8, Sonnet 5, Fable 5, Mythos 5 and newer — and left an env var to put them back. The scaffolding you built for last year's model is now the thing slowing it down.
