+## Consolidated skill location
+
+Task [#16](https://git.sendico.io/tech/sxchnge/issues/16) consolidates all four
+repository skills under `.agents/skills/`. UX Design and UX Observability moved
+without content changes; root policy links and this record now use that location.
+The old root `skills/` directory is removed. Validation compares moved content
+byte-for-byte, checks all four skill paths and updated UX links, and runs
+`git diff --check`. No runtime tests are needed for this move.
