Overview

Topic chip for a running development preview server. Unlike GithubPrChannel there is no external webhook source — the chip is populated by AI Agents (or humans) calling preview_attach/preview_detach MCP tools, one for each ./bin/dev they spin up alongside a worktree.

#default_label ⇒ Object

Chip fallbacks rendered immediately on attach, before the user has interacted with the chip. The label prefers the caller-supplied "Preview #42" style override and falls back to a localized default; the link is always the preview URL.

#handle(event:, payload:) ⇒ Object

PreviewChannel has no external event source — preview_attach/detach mutate the channel directly. The base handle would raise NotImplementedError, so override with an explicit no-op.
