# Startup Skills: Julien Thibeaut > Every skill by Julien Thibeaut in the index, with a line saying when to use each one. I index these, I do not host them. Every entry points at the original author's repo and carries a source byline. ## Entries (6) - [Baseline UI](https://github.com/ibelick/ui-skills/tree/main/skills/baseline-ui) by Julien Thibeaut: Use when UI code needs a fast cleanup of spacing, hierarchy and typography. - [Create DESIGN.md](https://github.com/ibelick/ui-skills/tree/main/skills/create-design-md) by Julien Thibeaut: Use when a product's design language needs documenting as a DESIGN.md for agents. - [Fixing accessibility](https://github.com/ibelick/ui-skills/tree/main/skills/fixing-accessibility) by Julien Thibeaut: Use when adding forms, dialogs or controls, or checking a page against WCAG. - [Fixing motion performance](https://github.com/ibelick/ui-skills/tree/main/skills/fixing-motion-performance) by Julien Thibeaut: Use when a transition drops frames and the cause is layout or compositing. - [Improve UI](https://github.com/ibelick/ui-skills/tree/main/skills/improve-ui) by Julien Thibeaut: Use when refining an interface means written plans for another agent, not direct edits. - [Fixing metadata](https://github.com/ibelick/ui-skills/tree/main/skills/fixing-metadata) by Julien Thibeaut: Use when share previews look wrong or new pages ship without meta tags. ## Links - [Page](https://startupskills.dev/ibelick): the same list, for a person. - [The whole index](https://startupskills.dev/llms.txt): all 189 entries. - [Skills index](https://startupskills.dev/skills): every skill, with search.
