What's Wrong?

Description:
Claude Code in VS Code periodically shows a prompt saying I need to purchase more Fable 5 usage credits. However, my weekly Fable 5 usage is at only 3% — far below the 50% plan-included cap during the current promotional window (extended through July 19).

The strange part: I never actually purchase anything. When I click the prompt, it opens my browser with my claude.ai session already logged in. Just opening the browser session is enough — Claude Code immediately resumes working with Fable 5, with no purchase or any other action on my part.

This suggests an entitlement/session sync issue: Claude Code seems to lose or fail to refresh my Fable 5 entitlement locally, and opening the claude.ai session in the browser refreshes the auth token, restoring access.

What Should Happen?

Expected behavior:
No credit purchase prompt should appear while Fable 5 usage is within the plan-included allowance. If the local entitlement/session needs refreshing, Claude Code should handle it silently instead of showing a misleading purchase prompt.

Error Messages/Logs

Actual behavior:
A "purchase more credits" prompt appears repeatedly despite usage at 3% of the weekly limit, and simply opening the claude.ai browser session (no purchase) restores Fable 5 access.

Steps to Reproduce

Steps to reproduce:

1. Use Claude Code in VS Code with Fable 5 as the model, on a paid plan within the promotional window
2. Work normally over time (weekly Fable usage well below 50% — mine is at 3%)
3. Periodically, a prompt appears asking to purchase more Fable 5 credits
4. Click the prompt → browser opens with claude.ai session → close it without buying anything
5. Claude Code resumes working with Fable 5 normally

Is this a regression?

Yes, this worked in a previous version

Last Working Version

Yes. When Fable 5 was first restored on subscription plans (around July 1), this did not happen — I used Fable 5 in Claude Code (VS Code) normally, within the plan-included allowance, and never saw the "purchase more credits" prompts. The prompts started appearing more recently, even though my weekly Fable 5 usage remains far below the included limit (currently at 3%). I'm not sure of the exact Claude Code version where the behavior changed, but it worked correctly in whatever version I was running in early July.
