We're building the eval infrastructure that makes AI agents safe to ship.
In 2024, teams started shipping AI agents faster than they could evaluate them. A model update would silently degrade quality. A new prompt would fix one persona while breaking another. Engineers found out via support tickets, not dashboards.
We'd seen this pattern before — in software testing, in ML validation, in every engineering discipline where "seems fine" wasn't good enough. The solution wasn't more manual testing. It was the right fixture.
A jig is a tool that holds a workpiece in exactly the right position so every operation is repeatable. Agent Jig is that fixture for your AI agent — it holds your agent still while you test it, every time, in CI, before your users see a single response.
AI agents are becoming load-bearing infrastructure. They handle customer support, process refunds, book appointments, write code. The quality bar is no longer "good enough for a demo" — it's "reliable enough to trust."
Agent Jig exists to make that bar measurable. Not "we think it's better" — five more scenarios passing, zero regressions, baseline locked.
We believe every team shipping an AI agent deserves a CI system that catches quality regressions before production. That's the future we're building toward.
Start evaluating free →Every eval produces a pass or fail. Score is a number, not a feeling. If you can't measure it, you can't improve it.
Eval scenarios are code. They should live in your repo, be reviewed in PRs, and evolve with your agent. YAML, not spreadsheets.
Running evals manually before a deploy is better than nothing. Running them automatically on every commit is the only thing that scales.
Your eval cases are plain YAML. Your agent is yours. Agent Jig is infrastructure — it should be replaceable if something better comes along.
Going forward is optional. Going backward is unacceptable. Every deploy should be provably no worse than the one before it.
Agent Jig is a developer tool. It fits in a terminal, in a config file, in a CI step. No dashboards required unless you want them.
