What

Claude Code hides secrets such as keys by replacing them with [REDACTED]. For one kind of signed key, the start of the key was hidden but the long remainder after it, beginning eyJ, could stay visible. Claude Code now hides that remainder too.

Why

Secrets are less likely to leak into transcripts and logs.
