The current text contain repetitions and inconsistencies. Also, I think there are some cases where Jenkins CI doesn't have any added value (linter changes, adding GH actions scripts, doc generation tool updates, etc.) but it's still required today.

This PR suggests to list folders where the full Jenkins CI is actually needed. For changes outside of those critical folders, I think GH actions results would report all the relevant mistakes already.

/cc @nodejs/tsc

If this change is accepted, I can work on a PR to reflect this change on node-core-utils.

Unfortunately I think this will end up being very complicated. We absolutely need to run a full Jenkins CI on anything that touches a build file (e.g. any of the .gyp files including the ones in the root directory and tools/v8_gypfiles). Also other directories under tools such as gyp, icu, inspector-protocol, snapshot, etc. All of those contain either source or a tool that could break on any of the platforms that the Jenkins CI covers that are not available from GitHub.

No, it would miss things like (not exhaustive) tools/build-addons.js, tools/genv8constants.py, tools/js2c.py, tools/test.py, tools/v8_gypfiles

lgtm

platforms are only kept for seven days.

#### Useful CI jobs
A green GitHub Actions CI result is required. A passing

Yellow is also OK.

Oh, wait, GitHub Actions CI. Yeah, so maybe it is just green.

We've never required GitHub Actions CI be green before. This would be a big change in the process. I'm not opposed, necessarily, but I want to highlight this here so it doesn't escape notice.

Since this is getting approvals, I'm going to make my concerns with this explicit. Our CI requirements are already confusing, especially to newcomers to the project (who might just expect the GitHub actions to be sufficient), and this change introduces more complexity (which I think will be unavoidable with the current mix of stuff that lives in tools/). We do not require collaborators use node-core-utils, which means our rules should aim to be simple to follow.

If we do make changes it may be simpler to state when GitHub actions only is sufficient (e.g. in addition to documentation-only changes, add changes to .github, etc.).

Even "(except it only changes comments)" is not something I'm entirely comfortable with as it's perfectly possible to break code when changing comments, e.g. mismatched /* and */ in C/C++ which could always be inside #if def's so wouldn't necessary be caught in the actions CI.

I put it there because it was already in the rules – I didn't know about it before working on this PR, and I suspect most collaborators haven't heard of it either.

Hum OK, my aim was actually to simplify the requirements by allowing more PRs to land without going to the Jenkins full run (which is sometimes flaky and causes confusion to new contributors). But I get your point, we should try to improve the collaborator experience as well.
I was thinking we could make the boot assign the needs-ci label to the PRs that introduce changes to the listed files. Also, we can add another rule: "When in doubt, spawn a Jenkins CI" (which is already implicitly the case).

If we do make changes it may be simpler to state when GitHub actions only is sufficient (e.g. in addition to documentation-only changes, add changes to .github, etc.).

That's something I've considered, I'm not sure it'd be ideal in the long run though: I think most files that are being added to the repo are either not related with the build process, either inside one of the listed folders; that would make the list go out-of-date quicker than the current one. Anyway, if that's the way we decide to make it, the exception list would look something like that:

* `*.md`,
* `.eslintrc.js`,
* `benchmark/`,
* `doc/`,
* `tools/actions/`,
* `tools/doc/`,
* `tools/eslint-rules/`,
* `tools/node_modules/`,
* `tools/node-lint-md-cli-rollup/`,
* `tools/lint-*.*`,
* `tools/release.sh`,
* `tools/update-authors.js`
* `tools/osx-*.sh`

Adding the blocked label to avoid this to land too soon – I'd like to get more reviews, and to be sure this has consensus we can maybe wait for the next TSC meeting.

To the best of my knowledge, this all makes sense, is accurate and IMO doesn't complicate things.
