Curtis kept seeing this warning every time he started soma:
Warning: Project tools/ directory contains custom tools. Custom tools have been
merged into extensions.
Move your extensions to the extensions/ directory.
Migration guide: https://soma.gravicity.ai/docs/updating
Documentation: https://soma.gravicity.ai/docs/extending
Press any key to continue...
His project had a .soma/tools/ directory. It contained Python scripts —
compare-pages.py, folder-audit.py, scrape-page.py, etc. Workflow tools
he uses while working on his client sites. Nothing about extensions.
The warning was wrong on every count it could be wrong on:
- Wrong target.
.soma/tools/was never a Soma extension convention. Soma’s extensions live in.soma/extensions/. Soma’s scripts live in.soma/amps/scripts/. - Wrong remediation. “Move your extensions to the extensions/ directory” would, in his case, move Python scripts into a directory designed for TypeScript extension code. The shapes don’t even match.
- Wrong audience. Soma never had this Pi-rename history. We inherited the warning code from upstream Pi, where it had once made sense for Pi-internal users migrating between Pi versions.
He’d been pressing any key to continue, every startup, for weeks. The fix was about ten lines of code to gut. We did that. But that wasn’t the interesting part.
The interesting part
The interesting part was: what should that interactive moment have been?
The warning had something good buried in it. It was a preflight prompt
— a hard pause before soma ran, where the user had to acknowledge
something. The mechanism was right. Only the content was wrong.
What’s a legitimate reason to interrupt a Soma startup?
When there’s a Soma update available.
We already had the plumbing. soma-statusline runs a periodic background
check (git fetch origin --quiet, see how far behind main HEAD is) and
caches the result in ~/.soma/config.json:
{
"updateAvailable": true,
"latestSummary": "feat(boot): preflight prompt for pending updates",
"updateCheckTs": 1714780000000
}
Zero network at boot. Just read the cache.
So we repurposed the prompt. Same mechanism, new content:
⬆ Soma update available— feat(boot): preflight prompt for pending updates
(c)ontinue (u)pdate now (s)kip this version
Three keys:
c(or Enter) — continue boot at the current version. Default action.u— runsoma updatesynchronously, then exit so you re-runsomawith the new code. One keystroke to upgrade.s— skip this update batch. Won’t re-prompt until newer commits arrive.
The skip is subtle. We persist skipUpdateUntilTs: <timestamp> to
~/.soma/config.json. Next boot, checkPendingUpdates only fires if
updateCheckTs > skipUpdateUntilTs — meaning new commits have arrived
since the last skip. You’re never stuck on a stale reminder. New work
comes in, the prompt fires again. You skip again, it stays quiet again.
Why this matters
Most agents don’t gate startup. They start, then maybe show a banner the user ignores. The banner is in the cached prompt prefix, so editing it is expensive. So nobody edits it. So nobody pays attention.
A modal preflight is different. It interrupts. It demands one keystroke. That keystroke is cheap to ask for — the user is already in their terminal, fingers on the keyboard, mind on the next task — and the information density is high: “your tool has new code, here’s the change, upgrade or skip.”
The pattern was hiding in plain sight under the misfiring warning. Pi had the right shape; we’d just inherited it pointing at the wrong target.
What also got fixed
While we were in the migrations file, we found a related bug. The
sentinel-based migration framework (introduced in v0.23.1 to flip
breathe.auto from true to false exactly once) was gated behind
if (status.needsMigration) — which only fires when the project’s
.soma/settings.json:version is older than the agent’s version.
Which means: if a user was on the current version when a migration
shipped (perhaps because their project was freshly initialized at the
new version, or they manually edited version in settings.json), the
migration never ran. The sentinel never recorded. The next time we
shipped a migration that did fire — for some other reason — the gate
would still skip. A dormant pile of “should have run but didn’t” was
accumulating.
We lifted the applyOnce() block out of the version gate. Now sentinel
migrations run on every boot. The first time, they apply (or detect
“nothing to do”) and stamp the sentinel. Every subsequent boot is O(1)
— the sentinel check returns early. No wasted work. And if the sentinel
isn’t there, we’re guaranteed to try, regardless of version state.
The shape
Sometimes the right move isn’t to remove what’s broken. It’s to keep the shape and replace what’s pointed at.
The interactive prompt was good UX. The content was wrong. We swapped the content. Same machinery, better signal.
There’s one of these in your codebase too. The deprecated-but-still-fires warning. The configuration that no one reads anymore. The startup banner that scrolls past. Each one is a moment of user attention, currently wasted. What would you put there if you took it seriously?
