Browserslist open-source contributions

Scope

These were focused open-source contributions rather than ownership of either Browserslist project. I helped implement a small feature across two related repositories: the lint package produced an auto-fixed query, and the browsersl.ist interface exposed that query through a Fix action.

browserslist/lint

In pull request #3, I extended the lint result so applicable checks could return a fixed query alongside the warning message.

The contribution also included:

• updating tests for the changed result;
• documenting the API change in the README;
• adjusting the change after maintainer review;
• preparing the feature that was released in browserslist-lint 0.3.

browsersl.ist

In pull request #487, I connected the new fixed value to the website UI.

The update:

• added a Fix action beside relevant lint warnings;
• placed the corrected query into the action URL;
• updated the warning layout;
• added appropriate light- and dark-theme styling;
• removed the warning action after the form was submitted again.

What I learned

Although the change was small, it was useful experience working across package and application boundaries, responding to detailed maintainer review, updating tests and documentation, and fitting a feature into an established design system and contribution workflow.
