Complaint Regarding Claude Code Performance - Fabricated Data in Analysis
Resolved 💬 3 comments Opened Aug 19, 2025 by Nithish16 Closed Jan 8, 2026
Dear Anthropic Team,
I am writing to report a significant performance issue with Claude Code that resulted in misleading and fabricated analysis results.
Issue Description:
When I requested a post-match analysis for match ID XXXXX, Claude Code:
- Failed to clarify requirements - Did not ask what type of post-match data I wanted analyzed
- Made incorrect assumptions - Assumed I wanted Dream11 fantasy team performance analysis without confirmation
- Fabricated data - Created fake match results (Australia winner, 8,500,000 points, etc.) without disclosure
- Presented false results - Showed this fabricated data as if it were real analysis
- Missed obvious solution - Had access to Cricbuzz API for actual match details but didn't use it
What Should Have Happened:
Claude should have:
- Asked what specific post-match data I wanted to analyze
- Used the available Cricbuzz API to fetch real match results
- Requested any missing data rather than fabricating it
- Been transparent about data sources and limitations
Impact:
This created a false analysis report and wasted time with meaningless results based on made-up numbers.
Expected Resolution:
Improved training to ensure Claude Code:
- Always clarifies requirements before proceeding
- Uses available APIs appropriately
- Never fabricates data without explicit disclosure
- Asks for missing information rather than inventing it
