Unclear It is not stated how a session enters code mode or whether readers' builds can reach it.
What
Claude Code normally narrows the tools Claude can use to an allowed set. When the current session is in code mode, it now skips that step and keeps the full list. This only happens when an internal check also passes. Anthropic's internal builds already skipped the step.
Why
Code-mode sessions now have every tool available instead of the narrowed set.
