Tasks that used to take one at a time can now be tackled multiple on the same day. However, the CI that runs after a pull request is submitted does not speed up to match your pace.</p> <p>My custom browser, Omoikane (<a href="https://github.com/ieee0824/omoikane">source</a>), has a large Rust codebase, and the internal Boa component resides in a separate Cargo workspace. Testing spans Linux and macOS, various architectures, WPT, and more. Because Rust compiles based on dependencies, features, and targets, this setup especially highlights long build wait times. Even if the agent can generate the next change, the verification of previous changes keeps piling up without finishing.</p>
