Overview
Who it's for
FrontierHarness Eval
Engineers choosing or building a coding-agent harness.I Have Been Clawed
Developers and teams using AI agents who want to learn from real failures.Problem
FrontierHarness Eval
It's hard to tell how much of an agent's cost and quality comes from the harness rather than the model.I Have Been Clawed
Agent failures are scattered across social posts and blogs, so the lessons get lost.Solution
FrontierHarness Eval
A controlled evaluation where every run uses the same model, hardware and fresh checkpoint, so only the harness changes.I Have Been Clawed
A source-linked index of incidents with damage categories, severity and takeaways.What makes it unique
FrontierHarness Eval
All 360 trials start from the same fresh checkpoint restore to avoid warm-cache bias, and you can run it on your own harness.I Have Been Clawed
Every incident is tied to a source, with an archived copy and a stated lesson.
