Jev is now on the Lovable AI Gateway and it's free to try.
From now through Sunday, 9/27 23:59 UTC, it's free to build AI-powered features with Jev.
Go see what you can ship.
An error string is not an error contract.
Separate transport failure, provider rejection, policy denial, and business conflict. Typed errors let the harness retry, escalate, or stop without guessing from prose.
What decision is your loop making from a message it had to interpret?
Validate the read again before the write.
The target can change while the agent plans. Recheck its version at commit and reject stale intent before it overwrites a newer decision.
Where can your agent act on state that no longer exists?
Review the behavior delta before release.
Show what changed across prompts, tools, permissions, memory rules, and stop conditions. The code diff can stay clean while the agent gains a new path to production.
Which control change is invisible in your current review?
Retry is not one decision.
Transient, throttled, conflicting, and permanent failures need different control paths. Classify the error before spending another call on the same action. Some runs should wait. Some should reconcile. Some should stop.
Which failures does your loop retry blindly?
Escalation is an artifact, not an alert.
Send the blocker, attempted actions, current state, evidence, and exact decision needed to one named owner. A red notification without context only transfers confusion.
What does your operator receive when the loop gives up?
A model swap should not rewrite the production contract.
Permissions, tool semantics, output shape, and release criteria should survive a provider change. When the model owns those rules, portability exists only in the architecture slide.
Which invariant would fail if you changed models today?
Four AI builders. One prompt. Built live.

No polished demos. Just live building.

A useful trace should not become a secret leak.
Redact credentials and sensitive fields before telemetry leaves the run. Keep the decision evidence, identifiers, and error class without copying the risky payload into every log sink.
What should never cross your observability boundary?
Loved hearing @AlexCinovoj share what makes the @Lovable Discord community special, especially the real experiences and insights coming directly from @Lovable Champions. 💙
More than a community, it feels like a place where builders genuinely learn, experiment and grow together.

A sandbox still needs a fencing token.
A stale worker can outlive its lease and write after a replacement starts. Require a current token at commit so the old owner cannot mutate the new run's state.
What prevents a late writer in your system?
Your agent queue needs a refusal mode.
When arrivals exceed safe capacity, slow admission or shed work deliberately. Accepting everything creates stale context, late side effects, and retries against decisions that already changed.
Where does your queue apply backpressure?
Partial success needs its own receipt.
Record what completed, what failed, and which side effects remain uncertain. A binary pass or fail hides the exact boundary a retry needs to resume safely.
What does your harness return when only half the work lands?
