Permission checks for handed-off skill shell commands now always see the tool in the tool list

What

Skills can include inline shell commands that Claude Code sometimes hands to the model to run explicitly instead of executing automatically. When that handoff happens, the permission check that decides whether the command is allowed now always runs with the tool included in the available tool options, adding it if it wasn't already present, rather than only sometimes including it.

Why

This makes the permission decision for handed-off shell commands more consistent, so the check isn't skipped or handled differently depending on whether the tool happened to already be in the list.

The writer flagged doubtIt is unclear what user-visible difference this makes, since the gate controlling this handoff path has no known configuration read.
