| name | marketplace-handoff |
| description | Decide when a purchasing question has stopped being about the product and become a question about a specific marketplace, and hand it to that marketplace's dedicated plugin instead of answering it here. Use mid-workflow when a comparison, price check or delivery question narrows to one named marketplace. The roster of which marketplaces have plugins is maintained in the shopping plugin's marketplace-plugins skill, not here. |

Marketplace handoff
procurement-tools is the generalist ecommerce research plugin: intake, specs,
cross-vendor comparison, evaluation, recommendations, preference memory. It is
deliberately marketplace-agnostic, and it should stay that way.
This skill is the boundary rule. It does not carry a list.
The rule
Hand off when the answer depends on the marketplace rather than on the
product:
| Stays here | Hands off |
|---|
| What should I buy for this purpose | What does this cost on Amazon |
| Which of these three is better value | Is this ASIN in stock, and when does it arrive |
| What spec do I actually need | Which seller is behind this listing |
| Is it worth the upgrade | Does the price include a coupon I have to tick |
The test: could the answer change if the same product were sold somewhere else?
If yes, it is a marketplace question.
Why not just answer it here
The knowledge that makes a marketplace answer correct is specific and
volatile — which fetch route reaches it, which of its fields lie, how its filter
grammar composes, what its delivery promise is conditional on, which facts only
render to a signed-in session. Encoding any of that here would make it stale
within months and wrong for every other marketplace.
If no plugin covers the marketplace, say so rather than improvising. A
guessed fetch route or an unqualified delivery date produces a confident wrong
answer, which is worse than "not covered yet".
Where the roster lives
The maintained list of marketplace plugins — which exist, what each covers, how
to install them — is the marketplace-plugins skill in the
shopping plugin.
It is deliberately in one place. Do not restate it here; a second copy goes
stale and then contradicts the first.
If shopping is not installed, the roster at time of writing was amazon-us
(Amazon.com US) and aliexpress-israel-skills (AliExpress Israel) — but check
the live list rather than trusting that sentence.
Carrying the answer back
When a marketplace plugin answers, bring its caveats back into the
purchasing decision rather than flattening them into a number. A delivery date
that is non-Prime, a ZIP that could not be confirmed, a price that excludes an
untickable coupon — each of those changes a comparison, and each disappears if
you record only the figure.
Say which plugin produced the figure, so the recommendation carries its
provenance.
