Keep the review attached to the artifact and the next action.

“Looks good” in a chat is convenient. A specific comment attached to
the right version of the right screen is useful.
/carbon-feedback creates a scoped CARBON Feedback Loop
around an artifact: a URL, image, document, API, code surface, or other
review target.
Ask for the feedback you
need
Suppose you want a product owner to review a cancellation
explanation. Give the reviewer the artifact, the relevant context, and
the question: does this accurately describe what happens to access and
billing?
The feedback should return as durable context the agent can use, not
a vague instruction to rewrite everything. Fix-and-retest work needs to
retain which version was reviewed and what changed afterward.
The local user can respond in a protected HTML workspace. For
external reviewers, CARBON includes a self-hosted server path with
reviewer and queue workflows. Deployment to your own private environment
or public HTTPS host is an explicit choice; the command does not
silently send artifacts to a managed public service.
Keep the invitation scoped
/carbon-feedback prepare a local review of the cancellation screen; ask about wording, consequences, and recovery; do not send invitations yet
Rich email invitations link to a review workspace. They should not
promise that every mail client can safely run an embedded form. Sharing,
recipients, expiration, and access need deliberate configuration.
The value is continuity: the developer's question, the reviewer's
answer, and the resulting investigation stay connected.
Feedback becomes part of the quality record instead of one more
comment everybody remembers differently.
