How the agent did it
- Begin development with Claude on the Windows video utility.
- Switch exclusively to Codex during development.
- Build thumbnail and Preview Pane handlers for 10-bit videos.
The author built a Windows shell extension that renders thumbnails for 10-bit videos, addressing a capability they said Windows did not provide out of the box. They also built a Preview Pane Handler for those videos. The development began with Claude, then switched exclusively to Codex after the author found it had improved during the project.
The reported work extended beyond the C++ components. The author used AI coding for WIX installers, the product website, and Stripe integration. They also created a bespoke license generation system connected to checkout. These are separate delivered parts of the product described in the post, although the author did not explain their internal implementation or provide the prompts used.
The author believed they had written no C++ themselves. They did make minimal manual adjustments to the WIX installers and website. The post linked the product at ruptureware.com, but did not describe testing procedures or sales results. Who it's for: Developers exploring AI assistance across a Windows utility and its supporting distribution and payment components.
