Checks say what passing looks like

Improved

• Polished Settings with a unified single-column layout, title-only headers, and streamlined controls across every section.
• Simplified Model settings with live catalog search, helper setup upfront, and clear error states.
• Verification checks show expected vs. actual outcomes and guide the agent on how to satisfy failing tests.
• File formatting runs your project's local toolchains (such as Prettier, Ruff, or cargo fmt) before falling back to system binaries.
• Verification status accurately scores all required checks against declared criteria before marking work complete.
• The agent persists through required verification checks until tests pass.
