Should concurrent tool execution be allowed?

[khushalsagar]

Since tool execution is async, multiple tools can be invoked in parallel. We should define whether that's expected behaviour that the site author should be expected to handle. I think yes, there will be enough cases where that makes sense and parallel execution will be a perf boost.

We can consider an annotation to indicate if a tool should be executed serially if there's cases where site authors need that guarantee.

yes it should be allowed and shouldn't be our concern

all these tools are regular functions at the end of the day, so the author of them should take into account that they can be called in quick succession (i.e. before the first one completed).

i don't think this proposal needs to be concerned with userland architectural decisions like that

all tools will essentially be awaited (or callback-style, whatever we go with in the end). the tool author can block until previous tool calls finish if they must.
