Tiered error handling - Four levels: Warning, Error, Critical, Security - Implemented automated responses appropriate to each level - Prevented infinite loops in error handling #### 4. Improved progress tracking - Checklist-style execution plan for standard and critical tasks - Visual progress indicators (✅⏳⬜) for long-running work - Simplified reporting rules for lightweight tasks with concise 1–2 sentence summaries instead of fixed-interval updates #### 5. Strengthened quality management - Introduced a stepwise verification process - Improved handling of linter errors - Enhanced type safety #### 6. GPT-5 optimization - Prompt design to maximize GPT-5 capabilities - Execute more instructions without contradictions - Improved adherence to custom instructions #### 7. Simplified documentation structure - Removed detailed examples of technology stacks - Removed directory structure examples - Focused the document on the update history #### 8. Slash command conventions - Added explicit rules for treating `/`-prefixed inputs as executable commands - Clarified that the assistant should not modify command files - Ensured only explicitly provided arguments are passed to slash commands, leaving other parameters to command defaults ## Version 2 (2025-03-01) ### Highlights #### 1.
