Use this skill when migrating a Taiga UI project to a new major version. Before starting, confirm with the user which major versions are involved (e.g. v4 → v5). Substitute the source version as CURRENT_MAJOR and the target version as NEXT_MAJOR throughout this workflow. Also invoke when running migration schematics, handling migration TODOs left after `ng update` or `nx migrate`, asked to fix TODOs, clean up migration notes, resolve deprecation warnings, or work with @taiga-ui/legacy package. Follow the complete migration workflow: gather context, prepare environment, run schematics, review changes, handle TODOs, and troubleshoot common issues. Resolve every actionable TODO only when the surrounding code proves the fix is safe; otherwise inspect more context or ask the user before changing behavior, templates, styles, or scripts.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
