Comment Thread
A thread pinned to a clause or a cell: Enter sends, @ opens the people you can mention, your own comments can be edited or deleted, and resolving folds the thread to one line. CommentsPanel lists every thread with All, Open, Resolved and Mine.
The decision inside it
An agent's reply always says AI
A model's comment is marked AI next to its name, never only by its avatar, so people always know which replies a person wrote.
When to use it
Use Comment Thread for discussion pinned to one thing (a clause, a cell, a frame) with replies, @mentions and resolve. Use CommentsPanel beside a document to list every thread with Open, Resolved and Mine filters. For a chat between people and an agent, use the chat components.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Comment Thread for this.
Install it: npx shadcn@latest add @layro/comment-thread
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/comment-thread.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
Usage
import { CommentThread, type Comment } from "@/components/ui/comment-thread";
export function ClauseComments({ comments, reply, resolve }: { comments: Comment[]; reply: (body: string) => void; resolve: (done: boolean) => void }) {
return (
<CommentThread
anchor="Clause 4.2"
comments={comments}
currentUserId="michael"
mentionable={[{ id: "olivia", name: "Olivia Martinez" }, { id: "sarah", name: "Sarah Anderson" }]}
onReply={reply}
onResolve={resolve}
/>
);

Props
Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.
| Prop | Type | Notes |
|---|---|---|
commentsrequired | Comment[] | Oldest first. The first comment opens the thread. |
resolved | boolean | Folded to the first comment with a "Resolved" summary. |
mentionable | MentionablePerson[] | Who @ can mention. |
currentUserId | string | You, for Edit and Delete on your own comments. |
anchor | string | What the thread is attached to, shown above it ("Clause 4.2"). |
onReply | (body: string) => void | Send a reply. Without it there is no reply box. |
onResolve | (resolved: boolean) => void | Resolve (true) or reopen (false). Without it there is no Resolve button. |
onEdit | (id: string, body: string) => void | Save an edited comment. |
onDelete | (id: string) => void | Delete a comment. |
look | Look | Layered rests the thread in a tray with Resolve in the strip below. Default layered. |
placeholder | string | The reply box's placeholder. Default "Reply…". |
