# Claude Code History Analyzer - Fixed Version
|
||||
# Key fixes:
|
||||
# 1. Simplified jq syntax (remove != null checks)
|
||||
# 2. Better error handling for empty results
|
||||
# 3. Validate temp files before JSON generation
|
||||
# 4. More robust file processing
|
||||
|
||||
# Parse arguments
