Problem Statement

In the Claude Desktop Code tab, a link clicked in the transcript opens in the built-in Browser pane, and the next link to the same site replaces the page in that site's tab. That works well for GitHub PR links.

Jira Cloud links (https://<tenant>.atlassian.net/browse/KEY) never get that behavior: they always open in the system browser, even with links-in-preview enabled. The renderer bundle has a hardcoded list of hosts that are always sent to the system browser:

(^|\.)(slack\.com|linear\.app|notion\.(?:com|so)|zoom\.us|atlassian\.net)$|^(?:docs|drive|meet|calendar|mail|chromewebstore|chrome)\.google\.com$

No setting reaches it, and since the UI is loaded from claude.ai, it cannot be adjusted locally either.

For teams that track work in Jira, issue links show up in the transcript as often as PR links, so in a typical session half of the links open next to the session and the other half jump out to another app.

Proposed Solution

A setting (user and managed) listing hosts that may open in the Browser pane despite the default always-external list, so atlassian.net can be opted in. Tab reuse needs no change: the pane already reuses the open tab of the same origin, so each Jira link would replace the Jira tab the way GitHub links replace the GitHub tab.

Alternative Solutions

• Drop atlassian.net from the default list. Jira Cloud pages load fine in the pane when Claude's own browser tools open them, and the sign-in persists like GitHub's.
• Workarounds tried, none viable: there is no alternate Jira hostname that redirects to atlassian.net; a link through a redirect host opens in the pane but creates a new tab per click, because tab reuse matches the tab's current origin; the local ion-dist copy is only used offline/third-party, so patching it has no effect.

Priority

Medium - Would be very helpful

Configuration and settings

Use Case Example

1. Claude finishes a task and reports the PR and the Jira issue as links.
2. The PR link opens in the Browser pane, next to the session.
3. The Jira link opens a new tab in the system browser, so checking the issue means switching apps and back.

With the change, both open in the pane, one tab per site, each new link replacing the page in its site's tab.

Additional Context

Claude Desktop 2.7032.0 (Linux, deb), Code tab; links-in-preview enabled and the Browser pane opening GitHub links as expected.
