CLAUDE_CODE_SKIP_PROMPT_HISTORY
What
The check that decides whether a prompt is too sensitive to save now sees the actual pasted text, not just a flag saying a paste happened, so a command with a secret pasted into it can be kept out of history. Only text pastes are inspected. Setting CLAUDE_CODE_SKIP_PROMPT_HISTORY still disables history entirely.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
