Build [Windows desktop utility] using [C# and WPF]. Read the design and project documents before each session. Implement one feature at a time, build and test it, measure rendering and mouse behaviour, and wait for my debug-build review before committing.

- Reported result
- The builder reports a working open-source Windows usage meter, nearly all code and tests written by Claude Code, and roughly 350 tests. The app is not yet code-signed; its functionality was not independently tested here.
- Human involvement
- The author designed the app, made decisions and manually tried debug builds before commits. The source does not claim an unattended build.

How the agent did it
- Write repository design and project documents for Claude Code to read each session.
- Have Claude implement one WPF feature, build it and run tests.
- Check offscreen rendering, real mouse interactions and actual provider responses.
Reddit author 29ardayildiz wanted to stop switching between browser usage pages while working. They built OrbMet, a small Windows screen-edge strip with a usage ring for each tool. Their account explicitly separates the roles: the author designed the application and made decisions, while Claude Code wrote nearly all the C# code and tests.
The build used .NET 10 and WPF. A design document and project document in the repository gave Claude the current decisions at the start of each session. The author worked in small increments: one feature, a build, tests, a manual trial in a debug copy, then a commit. They report about 350 tests.
Verification included offscreen renders, real-mouse drag tests and reading actual provider responses before implementing parsers. The author says testing real clicks mattered because preventing a Windows window from stealing terminal focus required more than one flag.
Claude Code usage arrives through a status-line helper that preserves the existing status line. Codex limits use its app-server interface. Missing or expired data is hidden rather than presented as zero usage. The resulting MIT-licensed app is available for Windows 10 and 11, though it is not yet code-signed. These are the builder's claims, not an independent compatibility test. Who it's for: developers using a coding agent for a small desktop application while retaining design and acceptance decisions.

Frequently asked questions
Did Claude Code design the application independently?
No. The author says they designed it and made the decisions, while Claude Code wrote nearly all code and tests.
Are the reported results independently verified?
No. This entry describes the original author's account and preserves its limitations. Agents In Use has not reproduced the workflow.
