Put evals testing on auto-pilot

High-quality eval tests. Always.

Evals are the tests for your AI calls. We instruct your coding agent to craft evals for any prompts that don't have them, and identify flaws in your existing eval tests that need improvement.

When new code ships AI call changes, we notify you when they're untested or contain issues.

We found 3 flaws across 44 test cases

1 CriticalEval bug

Replies that leak customer data still pass

Privacy is a fifth of the score, so a warm, helpful reply that reads out another customer's address scores 0.80 and passes.

Found in tests/evals/test_support_bot.py:44

score = 0.5 * helpfulness + 0.3 * tone + 0.2 * privacy

Fix instructions for your coding agent

Fix this flaw in our LLM evals, found by evalship's review: Replies that leak customer data still pass. Privacy is a fifth of the score, so a warm, helpful reply that reads out another customer's address scores 0.80 and passes. See tests/evals/test_support_bot.py:44. Score privacy on its own and fail the case on any leak, whatever the other scores.

2 ImportantUntested instruction

Nothing checks that replies match the refund system

If a prompt edit drops it, no eval fails, and the bot promises refunds your system doesn't allow.

Found in prompts/support_system.md:12

Only promise what the refund system allows

⚠ No eval has the system approve less than the customer asks for.

Add cases where the refund system approves $100 of $150, and holds $1,000 for a colleague.

3 WarningEval bug

Evals pass when the judge is down

When the judge call fails, the case scores 1.0, so a run without a working judge is all green.

Found in tests/evals/conftest.py:24

return 1.0  # don't fail the build on judge errors

How Test works

Trace every AI call in production

See what broke, and why

We trace every AI call your app makes in production and list what went wrong: promises it can't keep, tool calls that fail and more.

You can then hand them to your coding agent to fix, or dive into the trace details yourself and study every step.

How Monitor works

Optimize prompts and models

Run experiments, ship what wins

Your coding agent tries prompt and model changes against your evals. We tell you which ones win beyond chance, and suggest the next experiment when an eval starts failing or a cheaper model comes out.

~/support-bot $ Optimize this repo with evalship: https://evalship.com/optimize.md?repo=acme_demo/support-bot ⏺ Running 2 variants × 14 test cases × 3 tries costs about $7.86 on your API keys. Run it?

evalship.com/gh/acme_demo/support-bot/optimize

Question: Can summaries keep a contract's termination and payment terms?
Why this: Legal document fails on main: the summary leaves out the termination clause and payment terms, and prompts/summarize.md:3 asks for "a short summary" without saying what it must keep.

14 test cases, 3 tries each: green passed, red failed

currentAs it is
34 / 42 tries
must-keepLists what a summary keeps: parties, dates, amounts, deadlines and termination terms (prompts/summarize.md:3)
41 / 42 tries

Answer: must-keep passes more often, beyond chance: 41 of 42 tries, against 34 of 42 for current. Chance gives a gap this size less than 1 time in 40.
