Just as a heads up @ARMmbed/mbed-os-maintainers (you administer the ciarmcom review bot I think?), this doesn't include any tool changes, only config changes to the library. So @ARMmbed/mbed-os-tools won't do a full code review on this unless otherwise requested.

you administer the ciarmcom review bot I think?

Yup.

@adbridge I'm confused as well as to why tools were poked for a review.

[bridadan]

@cmonr If I had to guess, there's some rule that says "poke tools team if any json is changed". There are some json files that are good to have a review (target.json, anything in /tools, etc).

@AdamZhang0124 Could you take a look at your PR's commit history? It looks as if you merged with master, which isn't supported by our release process.

Instead, to update a PR, you need to do a rebase.

@bridadan The rules for the tools team are:

"tools" : ["mbed-os-tools"],
"docs/design-documents/tools" : ["mbed-os-tools", "mbed-docs"],

So any changes under the tools directory will cause you to be tagged.

[bridadan]

@adbridge understood. Although the original changes have been removed, I remember there not being any changes under the tools or docs directories. Not a big deal, but just wanted to alert you in case the bot was having issues/rule mismatches.
