I think it helps, but it’s not the same as getting a notification for a
commit you’ve just made.

You can use ‘--display-missing’:

--8<---------------cut here---------------start------------->8---
$ guix weather --display-missing $(guix package -I |cut -f1)
computing 295 package derivations for x86_64-linux...
looking for 365 store items on https://ci.guix.gnu.org...

  95.6% substitutes available (349 out of 365)

  16.3 requests per second
  'https://ci.guix.gnu.org/api/queue?nr=1000' returned 504 ("Gateway Time-out")

Substitutes are missing for the following items:
  /gnu/store/0yjlganb3rw7jp1vw8hbpbbqf1myhmr2-sysstat-12.4.0
  /gnu/store/qnqny5gj6qrg5z1sa4wkcs6858mysvn4-emacs-strace-mode-0.0.2-1.6a69b4b

  […]
--8<---------------cut here---------------end--------------->8---

But then that doesn’t allow you to distinguish between failed builds,
things that are not built yet, and “dependency-failed” builds.

‘guix publish’ could perhaps somehow expose failed builds.  And then we
could improve ‘guix weather’ to find about failed dependencies (sort of
like ‘-c’ does actually).

Yeah, somehow.  :-)
