Typescript Expert

Build and manage pages, elements, components, and styles in Webflow Designer. Use when adding sections, creating layouts, building elements, inspecting or updating components, viewing what's inside a component, restructuring pages, creating new pages, previewing page structure, styling elements, or managing component properties. Building, styling, and inspecting run headlessly against an explicit page ID — no Designer connection needed. Designer is required for `designer_tool` actions (reading/switching the page open on canvas, interactively selecting an element, creating page folders, opening a component's canvas view) and for `element_snapshot_tool` visual previews.

PostHog developer CLI and repo tooling reference. Use when the user mentions hogli, asks about repo CLI tools, bin scripts, Makefiles, how to run/build/test/lint, or any dev environment commands.
