Having a "Recovery Mode"/"Safe Boot" flag to disable our configurations (or progressively enable) to see how claude code responds would be nice. Sometimes I get worried some old flag I set is breaking things. Maybe the flag already exists? I tried Claude doctor but it wasn't quite the solution.

For instance:

Is Haiku supposed to hit a warm system-prompt cache in a default Claude code setup?

I had `DISABLE_TELEMETRY=1` in my env and found the haiku requests would not hit a warm-cached system prompt. E.g. on first request just now w/ most recent version (v2.1.118, but happened on others):

w/ telemetry off - input_tokens:10 cache_read:0 cache_write:28897 out:249

w/ telemetry on - input_tokens:10 cache_read:24344 cache_write:7237 out:243

I used to think having so many users was leading to people hitting a lot of edge cases, 3 million users is 3 million different problems. Everyone can't be on the happy path. But then I started hitting weird edge cases and started thinking the permutations might not be under control.
