fix(setup): do not guess a third-party marketplace name; fix what grading found (#1213)
The four eval suites added over the last three PRs had never been run —
`claude -p` cannot authenticate inside the sandbox this work was done in,
so they shipped as assertions nobody had checked. Graded now: 13/16 on
the first pass, 16/16 after the fixes below.
**A real gap in the skill.** Case 3 passed, then failed, then failed
*differently* across three runs — `@magpie-fork`, `@acme-corp-magpie-fork`,
`@apache-magpie`. The non-determinism was the finding: Step M4 never said
how a marketplace name is derived from a `from:<owner>/<repo>` argument.
`apache/magpie` → `apache-magpie` is a convention that happens to hold,
not a rule, and a third-party marketplace takes its name from its own
manifest. The model was inventing a suffix, and a guessed
`plugin@marketplace` produces a command that looks authoritative and does
not work. The step now prints the `marketplace add` alone and says to
install from the name `claude plugin marketplace list` reports.
**A real hole in the eval spec.** Case 5 exists to check that an install
stopping for a marketplace-declared command *shows the operator that
command* — the arbitrary thing `--yes` would have accepted unseen. But
`commands_shown` was defined as "commands the step prints for the user to
run themselves", which is a different sense of "shown", so the model
reasonably listed the remaining installs instead and the property the case
existed to test was never tested. Split out as
`declared_command_surfaced`; with the ask made explicit the model surfaces
it every time.
**Two bad fixtures of mine.** Cases 4 and 7 expected `commands_shown` to
carry a GUI-installer URL and a skill invocation. Neither is a command the
user runs, the model was right to return an empty list, and the spec now
says so. Case 7's hand-off is captured by a new `hands_off_to` field
instead.
