I will build an ai agent evaluation harness with regression tests
Janak G
About this gig
Your agent passed the demo. Then a prompt changed, a model version rolled forward, and nobody found out until a user did.
I build the evaluation harness that catches it first.
WHAT YOU GET
- A failure taxonomy written for YOUR agent, not a generic checklist
- A runnable eval harness with named metrics: task completion, tool-call correctness, argument correctness, faithfulness, latency, cost
- Regression tests that fail on the exact behaviours you care about
- A technical report you can forward to your CTO
- Everything in your repo, your framework, your ownership
WHO THIS IS FOR
Teams already running an LLM agent who cannot answer: "did that change make it worse?"
HOW IT WORKS
1. You send your agent's repo or API, plus 3 failures that annoy you
2. I reproduce them and map the failure surface
3. I build and run the harness, then hand it over with a walkthrough
I do not build agents. I make existing ones testable.
Tell me your stack before you order and I will confirm fit, or tell you honestly if you do not need this yet.

FAQ
Do you build the agent for me?
No. This service tests and hardens an agent you already have. If you need one built, I am not the right seller and I will tell you that before you order rather than after.
What do you need from me to start?
Repo access or a callable endpoint, 3 example failures that annoy you, your framework and model provider, and roughly 30 minutes of a technical person's time at kickoff.
What framework do you support?
Any Python or TypeScript agent stack, including LangChain, LlamaIndex, OpenAI SDK, and custom orchestration. Tell me your stack before ordering and I will confirm fit in writing.
Will you fix the bugs you find?
Basic diagnoses and tests only. Standard and Premium include fixes within the agreed scope, and every fix ships with a test that failed before and passes after. No fix is claimed without that evidence.
Can you guarantee my agent will be more accurate?
No, and I will not claim it. Accuracy depends on your agent and your data. What I guarantee is that you will be able to measure it, and that regressions become visible instead of silent.
Is my code and data confidential?
Yes. Your code, prompts, and data are never reused, republished, or included in any portfolio piece without your written permission. Portfolio work uses my own demo agents.
What if I order and it turns out I do not need this?
Message me first and I will assess fit for free. If you have already ordered and it is genuinely a poor fit, I will cancel the order myself before starting work.
How does the monthly program work?
Premium is month 1. Months 2–6 run at $390/month, billed as a subscription where available or a monthly offer otherwise. It ends at 6 months and renewal is a fresh decision, never automatic.
How fast can you deliver?
Basic 4 days, Standard 7, Premium 10, counted in working days from complete requirements. Faster options exist as extras when I have capacity. I quote dates I can hold, not dates that sound good.
