Summary

Left alone, GLM 5.2 produces only basic frontend designs. When you give it a Claude Code skill with design-system guidance, the UI gets much better. The lesson is that packaged context (skills) can make up for a model's weak default style.

Key points

• GLM 5.2's default frontend output is basic.
• Adding a frontend design skill with design-system guidance greatly improves the result.
• Claude Code skills package reusable instructions or context that the model loads when needed.
• Compare with the Devin Desktop output made without a skill (previous post) to see the difference.
