Hi @m-shaka, could you please check this?

Hi @k2tzumi! Can you review this, you too?

q: Does the bundle size change every time?
Or does it change only when a specific file is changed?

Should I integrate workflow jobs when importing into #3491? Should we keep them separate? I am pondering.

it change only when a specific file is changed is right.

Only when a core file is changed.

Should I integrate workflow jobs when importing into #3491? Should we keep them separate? I am pondering.

I have limited knowledge about it, sorry.

[k2tzumi]

I want to run a job only when a core file is changed, can I identify the core file?
Also, will the number of target core file types increase or decrease frequently?

[EdamAme-x]

I think there will be little or no increase or decrease in the core file.
So it is a good idea to measure when it should be changed.

[EdamAme-x]

I would like to keep this as a TODO/NOTE as it seems a bit difficult to implement.

what happen, DDoS...?

[EdamAme-x]

hi @yusukebe, this pr should be ready.

[k2tzumi]

Looks good to me!

[m-shaka]

Sorry for being late. Great work!

It would be nicer if you could see a unit(like KB or MB) of bundle size, but it's OK to add it later

Agreed!
We will add custom metrics later, so it seems like a good idea to add them at that time.

[yusukebe]

LGTM!
