Why is order-assistant telling customers items are out of stock?

Replaying order-assistant episodes · checking tool results

The agent isn’t hallucinating — its tool is lying to it. Every stock check calls inventory.lookup(), which started timing out when product_catalog crossed its 16 MB limit, and the timeout comes back as an empty array. The agent reads [] as “out of stock” and says so, politely and confidently. Since the object crossed the limit, 38% of its replies are false out-of-stock claims and task success fell from 91% to 64%. The side-by-side is below.

FAQ

Why not charge for events, hosts, or seats?

  • We want to incentivize, not punish, sending more data: the more data you send to Foam, the better your experience will be.
  • We want your entire team to benefit from Foam: the fewer barriers to that, the better off you’ll be.

Do I need to uninstall other observability tools?

No. Foam runs alongside your existing tools, and during installation it verifies they keep working exactly as they do today.

How long does installation take?

2 to 5 hours for all your services, depending on complexity. It’s all hands-off: Foam opens PRs to provide full observability, then runs test traffic to verify every signal is captured and enriched.

What if I do not currently capture the logs or spans to answer a question?

Foam opens a PR adding the missing signals, and once deployed, it can always answer that question going forward.

Does it guarantee continuous coverage after installation?

Yes. Foam keeps monitoring your services after installation, searching for new gaps and proposing PRs to close them.

Are you compliant?

Foam is SOC 2 Type 1 and GDPR compliant. Full details in our Trust Center.
