What
Each command validated from a skill's preamble now gets its own tool-use ID rather than sharing the caller's, so results and permissions no longer collide between them.
Details
IDs take the form parent id + :preamble- + index; the Bash tool finds that marker in the id and recovers the parent id from the text before it.
The separate :inner suffix keeps its existing meaning.
Evidence
:preamble-
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
