The repo distributes three ways — the Claude Code plugin, the symlinked
library for Crush/Pi/OpenCode, and claude.ai, which has no fetch path at all —
and treated every skill as belonging to all of them. claude.ai is not a fourth
host to mirror: gitea-ci, playwright and web-shot have no shell and no cluster
there, so a flat mirror installs skills that can never fire and degrades
selection for the ones that can.
Every SKILL.md now carries `surfaces:`, defaulting to [claude-code, library];
dream, own-the-task and grill-me add `chat`, matching what is actually
installed on claude.ai today. Claude Code accepts the extra key —
`claude plugin validate` passes and the skills still load.
bin/check-surfaces validates values, not just presence, because the failure
mode here is silent: a wrong surface removes a skill from a harness rather than
erroring. install.sh links only skills whose surfaces include `library`, and a
source that declares nothing at all is treated as foreign and linked as-is —
Anthropic's official set has no reason to know this convention. doctor's
missing-link check skips non-library skills for the same reason.

~/.agents/skills was a single link straight at this checkout. That encoded an
assumption nobody had stated — that this checkout is the only source of skills
on the host. On flamingo it was not: Crush's directory held Anthropic's
official set, and the only way to install this library was to move that set
aside. A capability loss dressed up as a tidy-up.
The canonical location becomes a real directory of per-skill symlinks, fed by
the checkout plus anything in SKILLS_EXTRA_SOURCES. Harnesses keep their one
directory link, so the count is N + one per harness rather than N x harnesses,
which is what #23 was actually about.
The three requirements #27 named, each with a test:
- collisions are logged with both paths and the checkout wins, never resolved
in silence;
- removing a skill from a source prunes its link;
- anything in the managed directory that is not our symlink is reported and
left in place — the installer does not delete content it did not create.
doctor learns the same model: sources are recorded at ~/.agents/skills-sources,
a link into a configured source is healthy, a link into an unknown one is not,
and the old count check becomes a per-skill check because a per-skill layout
can lose one skill without changing any total. The pre-#27 wiring is named as
legacy rather than reported as damage. count_skills needed find -L; without it
symlinked skill directories count as zero.
Verified live on koala: migrated in place to 42 per-skill links, then a second
source added a 43rd alongside them, then a re-run without that source pruned it
back to 42. Only doctor finding throughout was the genuine stale plugin.
