What's Wrong?

Description:
I'm experiencing an issue where the "Recent activity" panel in Claude Code
is displaying work from sessions I didn't perform.

What I'm seeing:
In my Recent activity for the Ambassador-Scoring project, I see:

• 12h ago: check bot error (correct - this is mine)
• 12h ago: CMC URL Column Fix (correct - this is mine)
• 14h ago: Debugging Python Web Scraper with Selenium and BeautifulSoup (NOT mine)

Expected behavior:
The recent activity should only show activities from my own sessions in
this project.

Environment:

• Platform: macOS (Darwin 24.6.0)
• Project: Ambassador-Scoring
• Working directory: /Users/user/Desktop/dev/Ambassador-Scoring

Additional context:
The incorrect activity appears to be from a completely different project
(Python web scraping), while my actual project is related to bot commands,
CMC, and leaderboards. When I asked Claude about it, it confirmed having
no record of working on any web scraper in this repository.

This suggests either:

1. Activities are being mixed between different users/sessions
2. There's a caching issue mixing activities from different projects
3. The activity tracking is incorrectly associating external activities

with my current workspace
