MGS1102: this review provider does not implement that op
magus called one of the four reserved review ops and the wired spell does not export it.
[MGS1102] review provider: publish_review is not implemented by this spell, so
nothing was sent
Why
A review provider is a spell exporting up to four reserved function names -
find_review, review_threads, publish_review, reply_review. A spell may
implement a subset, and that is stated in the contract rather than tolerated:
a host with no comment API can still take a review body, so a missing op means
that provider lacks the capability, not that the spell is broken.
What matters is that a missing op means two different things depending on the direction of the call, and magus treats them differently:
- On a READ -
review_threadsagainst a host with no comment API - an absent op answers nothing, and nothing is the truth. The surface renders no conversation and says why. - On a WRITE -
publish_review- an absent op answering nothing would be read as success. The caller marks every draft published, publish only ever considers unpublished drafts, and the remarks are gone permanently. So a write to an op nobody implemented is an error, and this is that error.
That asymmetry is the whole reason the code exists. A tolerated silence is safe for a question and unsafe for an act.
Fix
- Check which spell is wired.
magus\review.provider(...)in your magusfile names it; the ops it exports are what magus can call. - Export the op, if the host supports it. See Authoring spells for the shape of a provider op and the parameters each reserved name receives.
- Use a different surface for that act. Where a provider cannot publish, magus will not fabricate a path that appears to - the remarks stay drafts and stay yours.
