+"""Seed the packaged install/uninstall skill into the user's store at setup time.
+
+A user who wants memU gone says "uninstall memU" — not "read SKILL.md and follow
+its uninstall section". An agent whose context holds no route to the packaged
+guide improvises, and an improvised teardown deletes too much (the store) or too
+little (the bridging task). Retrieval is a channel that can carry that route: if
+the root ``SKILL.md`` sits in the store as a ``skill``-track recall file, a bare
+"uninstall memU" can surface it on *any* host sharing the store — including hosts
+whose instruction file was never patched, or was hand-edited since.
+
+So setup plants it once. The seed is the packaged ``SKILL.md`` verbatim: its
+frontmatter is already the recall-file convention (``name``/``description``), its
+description already names the triggers ("install, set up, integrate, remove, or
+uninstall memU"), and that description is exactly what gets embedded — the
+retrieval surface. Committing through ``commit_results`` makes reseeding an
+upsert: a later install refreshes the stored copy instead of stacking a twin.
+
+The mirror under ``~/.memu/skill/`` is written too, for the same reason bridging
+mirrors everything: the agent's working medium is markdown on disk, and a seeded
+file the self-evolve loop cannot see is a file it would recreate or contradict.
