What
When Claude Code auto-repairs (coerces) a tool call's raw input before checking it against the tool's expected schema, it now records structured diagnostics about that repair: a shapeClass describing the input's shape, whether the repaired input actually passed validation, and a resultNote with more detail.
Why
This gives more precise information about why a tool call's input needed fixing, instead of only a simple pass/fail result, which should help diagnose tool-input problems.
