Omarchy
ProbeLabs65 findings · 95 requirementsA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.
diagnose-crash: the documented gdb line silently leaves the crashing program's own frames unsymbolized (needs -iex, not -ex)

Original report
What's wrong?
diagnose-crash (shipped in omarchy-settings, at /usr/share/omarchy/default/agents/skills/diagnose-crash/SKILL.md) tells the agent to symbolize a core like this (installed 4.0.3-1, lines 62-64; identical at current quattro HEAD):
DEBUGINFOD_URLS="https://debuginfod.archlinux.org" \
gdb -q <executable> "$core" \
-batch -ex 'set debuginfod enabled on' -ex 'bt'gdb asks "Enable debuginfod for this session? (y or [n])" during startup, before any `-ex` runs. In -batch there is no terminal to answer it, so it is auto-answered N:
Enable debuginfod for this session? (y or [n]) [answered N; input not from terminal]
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit.The later -ex 'set debuginfod enabled on' does re-enable debuginfod, so shared-library frames still symbolize — but the main executable's debug info was already looked up and abandoned during startup, and gdb never retries it. The frames that are lost are exactly the ones belonging to the program that crashed, while libc/GLib frames come back fine.
That is the worst possible split: the stack reads as "this program ships no debug symbols" when Arch does publish them and a single word (-ex → -iex) fetches them. The skill's own prose then steers the agent into that conclusion — "Many packages publish no debug symbols. When frames stay unresolved, say so — never invent function names to fill the gap." A session diagnosing a WebKitWebProcess SIGABRT hit precisely this: the documented line returned bare ?? frames for the crashing program's own frames and nearly produced a "no debug symbols for WebKit" report.
Reproduction
Crashing program /bin/bash — its debug info is on Arch's debuginfod server. Fresh $HOME per run (cold cache), gdb 17.2:
As documented (`-ex`):
$ H=$(mktemp -d)
$ env HOME=$H DEBUGINFOD_URLS="https://debuginfod.archlinux.org" \
gdb -q -batch -ex 'set debuginfod enabled on' -ex run -ex 'bt' \
--args /bin/bash -c 'kill -SEGV $$'
Enable debuginfod for this session? (y or [n]) [answered N; input not from terminal]
Debuginfod has been disabled.

Control — it is not a cache artifact. Re-running the documented (-ex) form against the now-warm cache, same $HOME: still 8 frames, still the same 3 ??, and 0 downloads — debuginfod is never consulted for the executable, cache or no cache.
What I expected
The documented command should symbolize the crashing program. Only the startup-time lookup is affected, so -iex (which runs before gdb's debuginfod prompt) is the whole difference.

### What's wrong?
`diagnose-crash` (shipped in `omarchy-settings`, at `/usr/share/omarchy/default/agents/skills/diagnose-crash/SKILL.md`) tells the agent to symbolize a core like this (installed 4.0.3-1, lines 62-64; identical at current `quattro` HEAD):
```bash
DEBUGINFOD_URLS="https://debuginfod.archlinux.org" \
gdb -q <executable> "$core" \
-batch -ex 'set debuginfod enabled on' -ex 'bt'
```
`gdb` asks **"Enable debuginfod for this session? (y or [n])" during startup, before any `-ex` runs.** In `-batch` there is no terminal to answer it, so it is auto-answered **N**:
```
Enable debuginfod for this session? (y or [n]) [answered N; input not from terminal]
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit.
```
The later `-ex 'set debuginfod enabled on'` does re-enable debuginfod, so **shared-library frames still symbolize** — but the main executable's debug info was already looked up and abandoned during startup, and gdb never retries it. The frames that are lost are exactly the ones belonging to the program that crashed, while libc/GLib frames come back fine.
That is the worst possible split: the stack reads as *"this program ships no debug symbols"* when Arch does publish them and a single word (`-ex` → `-iex`) fetches them. The skill's own prose then steers the agent into that conclusion — "Many packages publish no debug symbols. When frames stay unresolved, say so — never invent function names to fill the gap." A session diagnosing a `WebKitWebProcess` SIGABRT hit precisely this: the documented line returned bare `??` frames for the crashing program's own frames and nearly produced a "no debug symbols for WebKit" report.
### Reproduction

Verified: with `-iex` every frame symbolized and the executable's debug info was downloaded. A one-word change; the rest of the block is fine. (`set debuginfod enabled on` in a gdbinit would work too, but that is a persistent side effect a diagnosis skill should not create — one of gdb's own messages from this run is literally "To make this setting permanent, add 'set debuginfod enabled off' to .gdbinit".)
Worth also noting in the skill text: an unresolved frame in a stripped *system library* and an unresolved frame in the *crashing program* have different causes, and only the second one is a trap this snippet sets.
