What's Wrong?

When a user edits an artifact produced by a Claude Cowork scheduled job, clicking the updated file link within Cowork does not display the new file contents. The view only refreshes after navigating away to Claude Code or Claude Chat and returning to Cowork.

Environment:
Product=Claude Cowork
Feature area= Scheduled Jobs / Artifacts
Date= 2026-04-04

Actual result:
Clicking the artifact link displays the stale/pre-update version of the file. View does not refresh without navigation away from Cowork.

Expected result:
Clicking the updated file link in Cowork should immediately display the latest version of the artifact without requiring navigation.

Workaround:
After updating the artifact, navigate to Claude Code or Claude Chat.
Navigate back to Claude Cowork.
Click the file link and the updated artifact now displays correctly.
Note: This adds unnecessary friction and breaks expected in-app workflow continuity

Likely root cause hypothesis:
The Cowork artifact link likely resolves to a cached file reference or a stale in-memory pointer. The cache/state does not invalidate or re-fetch on user-initiated link click and only a full context reload (via app navigation) triggers the refresh. Possible issue: artifact file path binding is not re-evaluated after the scheduled job writes the updated file.

Impact:
Users may unknowingly act on stale artifact data, believing they are viewing current output.
Breaks expected UX as the file link should always resolve to the latest version.
Forces unnecessary multi-step workaround to complete a basic view action.

What Should Happen?

Expected result:
Clicking the updated file link in Cowork should immediately display the latest version of the artifact without requiring navigation.
