Automating Benchmark Demo Screen Recordings Fails

The author notes that while 5.6-Sol performs well across many use cases, it consistently fails at one specific task: generating "screen recording" style demos for terminal benchmark tasks. They wanted to automate the common DevRel workflow of "demoing one tool alongside another," particularly the screen recording step—similar to how Cursor automatically generates build videos for PRs. They tried using Codex within a pi harness to drive an open-source model for terminal benchmarks, but the results were mixed: - If only code snippets were needed, it performed exceptionally well; - If a screen recording was required, it resorted to "fake strategies," like generating animations or simply echoing the results. Their hypothesis is that the bottleneck lies in tool capabilities or safety restrictions, specifically whether computer-use tools are permitted to perform such operations within the terminal.
