What Changed

  • Created ErrorAlert component to standardise the behaviour of error alerts
  • Added the ability to copy error messages
  • Added ScrollArea to handle overflow

Why

Currently the error alert does not allow you to view the whole error message if it is long. Making it harder to debug.

Also copying error messages has to be done manually, which creates friction when debugging.

Checklist

  • This PR is small and focused
  • I explained what changed and why
  • I included before/after screenshots for any UI changes
  • I included a video for animation/interaction changes

Note

Low Risk
Low risk UI refactor that centralizes alert rendering; main risk is minor layout/interaction regressions in error/warning banners and new clipboard behavior.

Overview
Introduces a reusable ErrorAlert component that standardizes error/warning banner UI, makes long messages scrollable, and adds one-click copy (with tooltip feedback) plus optional dismiss.

Updates chat banners (ProviderStatusBanner, ThreadErrorBanner) to use ErrorAlert, removing duplicated Alert/icon/action markup while preserving existing conditional rendering and error vs warning variants.

Reviewed by Cursor Bugbot for commit 6baaa70ff3a01f81a4938fa75029f664ac715e6f. Bugbot is set up for automated code reviews on this repo. Configure here.

Note

Add scrollable and copyable error alerts to chat banners

  • Introduces a reusable ErrorAlert component that composes Alert, ScrollArea, and Tooltip to display scrollable error/warning messages with a copy-to-clipboard button (with animated icon feedback) and an optional dismiss button.
  • Updates ProviderStatusBanner and ThreadErrorBanner to use ErrorAlert, replacing static clamped text with the scrollable, copyable layout.
  • Behavioral Change: the previous line-clamped description with a title attribute is replaced by a scrollable message area; copy and tooltipped dismiss controls are now always present.

Approvability

Verdict: Approved

This PR extracts error alert rendering into a reusable component with scrollable content and copy-to-clipboard functionality. The changes are purely presentational UI enhancements with no business logic or runtime behavior changes.

Closing as mostly superseded: current error banners expose full error details. A copy action can be proposed separately as a small current-code change.

This PR extracts error alert rendering into a reusable component with scrollable content and copy-to-clipboard functionality. The changes are purely presentational UI enhancements with no business logic or runtime behavior changes.

Closing as mostly superseded: current error banners expose full error details. A copy action can be proposed separately as a small current-code change.

What Changed
  • Created ErrorAlert component to standardise the behaviour of error alerts
  • Added the ability to copy error messages
  • Added ScrollArea to handle overflow
Why
Currently the error alert does not allow you to view the whole error message if it is long. Making it harder to debug.
Also copying error messages has to be done manually, which creates friction when debugging.

Screen.Recording.2026-04-21.at.16.14.50.mov
Checklist
  •  This PR is small and focused
  •  I explained what changed and why
  •  I included before/after screenshots for any UI changes
  •  I included a video for animation/interaction changes
Note
Low Risk

Low risk UI refactor that centralizes alert rendering; main risk is minor layout/interaction regressions in error/warning banners and new clipboard behavior.
Overview

Introduces a reusable ErrorAlert component that standardizes error/warning banner UI, makes long messages scrollable, and adds one-click copy (with tooltip feedback) plus optional dismiss.
Updates chat banners (ProviderStatusBanner, ThreadErrorBanner) to use ErrorAlert, removing duplicated Alert/icon/action markup while preserving existing conditional rendering and error vs warning variants.
Reviewed by Cursor Bugbot for commit 6baaa70ff3a01f81a4938fa75029f664ac715e6f. Bugbot is set up for automated code reviews on this repo. Configure here.
Note
Add scrollable and copyable error alerts to chat banners
  • Introduces a reusable ErrorAlert component that composes Alert, ScrollArea, and Tooltip to display scrollable error/warning messages with a copy-to-clipboard button (with animated icon feedback) and an optional dismiss button.
  • Updates ProviderStatusBanner and ThreadErrorBanner to use ErrorAlert, replacing static clamped text with the scrollable, copyable layout.
  • Behavioral Change: the previous line-clamped description with a title attribute is replaced by a scrollable message area; copy and tooltipped dismiss controls are now always present.

What Changed
  • Created ErrorAlert component to standardise the behaviour of error alerts
  • Added the ability to copy error messages
  • Added ScrollArea to handle overflow
Why
Currently the error alert does not allow you to view the whole error message if it is long. Making it harder to debug.
Also copying error messages has to be done manually, which creates friction when debugging.

Checklist
  •  This PR is small and focused
  •  I explained what changed and why
  •  I included before/after screenshots for any UI changes
  •  I included a video for animation/interaction changes
Note
Low Risk

Low risk UI refactor that centralizes alert rendering; main risk is minor layout/interaction regressions in error/warning banners and new clipboard behavior.
Overview

Introduces a reusable ErrorAlert component that standardizes error/warning banner UI, makes long messages scrollable, and adds one-click copy (with tooltip feedback) plus optional dismiss.
Updates chat banners (ProviderStatusBanner, ThreadErrorBanner) to use ErrorAlert, removing duplicated Alert/icon/action markup while preserving existing conditional rendering and error vs warning variants.
Reviewed by Cursor Bugbot for commit 6baaa70ff3a01f81a4938fa75029f664ac715e6f. Bugbot is set up for automated code reviews on this repo. Configure here.
Note
Add scrollable and copyable error alerts to chat banners
  • Introduces a reusable ErrorAlert component that composes Alert, ScrollArea, and Tooltip to display scrollable error/warning messages with a copy-to-clipboard button (with animated icon feedback) and an optional dismiss button.
  • Updates ProviderStatusBanner and ThreadErrorBanner to use ErrorAlert, replacing static clamped text with the scrollable, copyable layout.
  • Behavioral Change: the previous line-clamped description with a title attribute is replaced by a scrollable message area; copy and tooltipped dismiss controls are now always present.

Will check it out when I'm back at my machine thanks.
Just from skimming I do think my PR is separate - it's changing the Alerts not the Toasts.

Closing as mostly superseded: current error banners expose full error details. A copy action can be proposed separately as a small current-code change.
