name: Comment with mypy_primer diff
on:
# pull_request_target gives us access to a write token which we need to post a comment
# The presence of a write token means that we can't run any untrusted code (i.e. malicious PRs),
# which is why this its own workflow. Github Actions doesn't make it easy for workflows to talk to
# each other, so the approach here is to poll for workflow runs, find the mypy_primer run for our
# commit, wait till it's completed, and download and post the diff.
pull_request_target:
# Since modular typeshed, mypy primer doesn't check third party stubs. Till that is changed,
# only run it on stdlib changes to avoid false confidence and wasted CI minutes.
