Unclear What permissionCard controls and what the wrapping helper (B_t) actually does are not specified in the finding.
What
Tool-permission prompt info can now include an optional structured card (with a question, lines, and values) shown when the permission decision reason is a safety check or similar, there's no matched ask-rule, and no denial-limit fallback applies. The card content comes from the tool's own permissionCard callback.
The generic addon-tool factory now includes a permissionCard property in the tool definition it builds, and wraps the finished tool object with a helper before returning it, so addon tools can supply this card.
Why
This gives you a clearer, structured explanation (instead of plain text) when Claude Code asks permission to run a tool for safety reasons, and extends that capability to addon tools.
