Unclear Whether the tengu_shiny_stardust gate controlling this behavior is switched on is unread and not stated by the finding.

What

Claude Code normally decides whether to load a tool's full details up front (eager) or defer/hide them until needed. A new branch in that decision logic makes a tool eager if it matches certain search criteria, on top of the existing rules that MCP (Model Context Protocol) tools are always loaded eagerly and tools explicitly flagged to defer stay deferred.

Why

Loading more relevant tools eagerly can make them available sooner without waiting for deferred loading, though whether this behavior is active depends on an internal setting that hasn't been confirmed either way.
