PR Review Summary

⚠️ Found 2 critical compilation errors that must be fixed before merging.

The Go 1.26 upgrade looks good overall, but there are invalid uses of the new() builtin. While Go 1.26 enhanced new() to accept non-constant type expressions, it still requires type arguments, not values or function calls.

Invalid syntax: new() called with a value instead of a type

The expression new(true) is invalid Go syntax. The new() builtin function requires a type as its argument, but true is a boolean literal/value, not a type. This code will fail to compile with an error like "cannot use true (untyped bool constant) as type in argument to new".

The field ParallelToolCalls is of type *bool, so the correct approach would be:

t := true
m.ParallelToolCalls = &t

Or use a helper function that returns *bool. Even though Go 1.26 enhanced the new() builtin to accept non-constant expressions, those expressions must still be type expressions, not value literals.

Invalid syntax: new() called with fmt.Sprintf expression instead of a type

The expression new(fmt.Sprintf("Maximum iterations (%d) reached", e.MaxIterations)) is invalid Go syntax. The new() builtin accepts only a type expression (e.g., new(string)), not a value-producing function call. fmt.Sprintf() returns a string value, not a type. This will fail to compile.

The correct approach would be:

title := fmt.Sprintf("Maximum iterations (%d) reached", e.MaxIterations)
Title: &title,

Or use the acp.Ptr() helper function if available (as seen elsewhere in the codebase):

Title: acp.Ptr(fmt.Sprintf("Maximum iterations (%d) reached", e.MaxIterations)),

Looking at line 753 in the same file, you correctly use &title for string pointers.
