Show HN: AJX – Find out where AI agents get stuck using your product

AJX is an open-source skill and CLI for agent usability testing that lets you test how AI agents use your website, CLI, SDK, API, or developer tool, recording the attempt, checking the result, and showing where the product made the task harder. It reports elapsed time, retries, and token usage where the harness exposes it, and produces a report connecting each proposed product change to supporting events plus a timeline of forks, blocks, waits, and recoveries. It supports local or Docker execution, comparison across harnesses and models, and CI runs via `ajx ci` that write JSON and JUnit results.
