skills

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.

Use this skill when writing or reviewing Taiga UI schematics migrations. Covers: analyzing API changes between major versions, choosing the right migration utility, writing tests with snapshots, and avoiding common pitfalls. Invoke whenever asked to add, fix, or review a migration in projects/cdk/schematics/.
