Diagnose why a program crashed on this machine, from a systemd-coredump core dump. Use when a process has segfaulted, aborted, or otherwise dumped core, when asked why an application crashed or disappeared, or when a "Process crashed:" desktop notification is acted on. Triggers: crash, segfault, SIGSEGV, SIGABRT, core dump, coredumpctl, "why did X crash", "X keeps crashing", backtrace symbolization. Covers reporting a confirmed Omarchy bug upstream — see reporting.md.

Reporting a Crash Upstream to Omarchy

Read this only after concluding that a crash is genuinely Omarchy's to fix.

Is it even Omarchy's bug?

Be strict here. Omarchy is a configuration layer over Arch Linux, so a crash inside a third-party application — a file manager, a browser, a GNOME or Qt library — is almost always an upstream bug in that project, not in Omarchy.

Omarchy's sphere of control is roughly:

  • the omarchy-* commands
  • the Quickshell shell and its plugins
  • the Hyprland and terminal configuration it ships
  • its themes
  • its install and migration scripts
  • how it packages and configures what it installs

A crash in a program Omarchy merely installs is not an Omarchy bug unless Omarchy's own packaging or configuration is implicated.

If it is not Omarchy's, say so and stop. Suggesting the right upstream project is useful; filing there yourself is not part of this.

Three conditions, all required

  1. It is a verified bug in Omarchy's sphere, established on evidence. Issues are for verified bugs only. An "is this even a bug?" belongs on the Discord at https://omarchy.org/discord; a feature idea belongs in GitHub Discussions under Suggestions.
  2. The user has explicitly agreed. Show them the exact title and body you propose, and wait for a yes. Never file unprompted.
  3. The machine can file itgh auth status must succeed. If gh is missing or unauthenticated, do not install or authenticate it. Say so, and hand the user the finished text to submit themselves.

Search before filing

A duplicate issue costs a maintainer more time than no report at all.

gh search issues --repo omacom/omarchy "<program> crash"
gh issue list --repo omacom/omarchy --state all --search "<signal> <program>"

Search on the crashing program, the signal, and distinctive symbols from the backtrace — not on the wording of the title you were about to write.

gh search issues accepts only open or closed for --state, and errors on anything else. Leaving it off searches both, which is what you want here.

Include closed issues. A matching issue closed as fixed, when the crash still reproduces on a current system, is a regression — and reporting that is worth far more than another duplicate.

Adding to an existing report

If a plausible match comes back, read it properly first:

gh issue view <number> --repo omacom/omarchy --comments

Confirm it is genuinely the same failure. The same program crashing is not the same bug if the trigger or the stack differs.

If it is the same, add to that issue rather than opening a new one — but only when you have something the thread does not already contain: a different reproduction, a symbolized stack where it has none, a narrower trigger, a version where it regressed.

A comment that only says the bug happens to you too is noise. If that is all you have, tell the user so and file nothing.

gh issue comment <number> --repo omacom/omarchy --body "..."

Filing a new issue

Only when the search turns up nothing that matches:

gh issue create --repo omacom/omarchy --title "..." --body "..."

Include what happened, what was expected, steps to reproduce, system details from omarchy version, and diagnostics from omarchy debug --no-sudo --print (which also writes /tmp/omarchy-debug.log; the interactive omarchy debug can upload it and print a shareable URL worth including).

gh cannot attach media. If a screenshot would help, save one and give the user the path to drag into the web form.

Signing

End the issue or comment with a line naming the model and agent harness that produced it, so a human reader knows it was machine-authored:

Filed by <model name> via <agent harness>.

Use your actual model and harness names. If you are not certain of them, say so plainly rather than inventing a version string.
