The Terminal chips on /download were static. Clicking one now copies the visible command and replaces the label with Copied to clipboard for 1.5s. Co-authored-by: Cursor <cursoragent@cursor.com>

ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a focused, single-page marketing enhancement that adds click-to-copy behavior to existing CLI commands while preserving their content and channel selection. Its browser-only clipboard handling, status feedback, and styling are isolated and low risk, with no API, deployment, security, billing, or product-default changes. You can add or adjust custom eligibility rules. Learn more. |

Clipboard API writeText promise ordering concurrent writes specification
💡 Result:
<search_synthesis>
The Clipboard API's writeText() method does not guarantee strict ordering for concurrent writes, and the specification does not mandate a queueing system to ensure that multiple, near-simultaneous calls are processed sequentially [1][2][3]. Key technical aspects include: 1. Specification Behavior: According to the W3C Clipboard API specification, writeText() performs its operations by queuing a task on the "clipboard task source" [1][3]. When multiple writeText() calls are initiated, the browser's underlying implementation generally processes these as independent requests to the system clipboard [4]. Because these tasks are queued, they may compete for the same system resource [4]. 2. Race Conditions: There is no formal specification requirement for a global lock or a serialized request queue across concurrent writeText() calls [1][3]. Consequently, if multiple writes occur in rapid succession, the final state of the clipboard is effectively a race condition—it will reflect whichever write operation completes last at the system level [4]. 3. Promise Resolution: The returned Promise for each writeText() call resolves once that specific operation has successfully updated the clipboard [5][3]. If one write operation is superseded by a subsequent one, the promise for the first operation may still resolve successfully, even though its data was overwritten immediately afterward [4]. 4. Best Practices: Due to this lack of implicit ordering, developers are advised to manage concurrency at the application level [6]. A common practice is to maintain a local "in-progress" flag or disable UI elements (e.g., a copy button) until the returned promise settles, thereby preventing overlapping write requests [6]. In summary, because the API interacts with a shared system-level resource without an application-level request queue, concurrent writeText() calls can result in non-deterministic outcomes [4]. Relying on promise resolution order is not a robust strategy for ensuring data integrity on the clipboard [4].

Serialize clipboard writes.
copyCliLine starts a new navigator.clipboard.writeText() call for each click without waiting for an existing call. The Clipboard API does not guarantee completion order for concurrent writes. If two writes complete out of order, the earlier command can overwrite the clipboard, copied label, and live-region update for the later click.
Disable the buttons while a write is pending, or serialize the write operations.

What Changed
Terminal install chips on
/downloadare now buttons. Click copies the visible command and replaces the chip label withCopied to clipboardfor 1.5s, then restores the command.Why
The chips were static
<code>. Getting them into a terminal meant selecting by hand. The chip is the control, so confirmation replaces its label — the same swap this product uses on copy buttons (Copy prompt→Copied) and the same click-the-command pattern as create.t3.gg. Clipboard payload stays the original command viadata-command, including nightly$env:...(never stripped as a prompt).Scope

A trailing
Copiedsuffix was rejected: it treats the chip as a snippet-plus-badge instead of a button whose label is the command. A separate copy icon was rejected: the user asked to click the command.Blast Radius
