Add debug info in AI chat (#15758)
## 🐛 Critical Bug Fix ### Cost Calculation Error (1000x undercharge) - **Fixed**: Cost conversion utility was calculating credits at 1/1000th of actual value - **Before**: `cents * 10` ❌ - **After**: `(cents / 100) * DOLLAR_TO_CREDIT_MULTIPLIER` ✅ - **Impact**: Users were being undercharged by 1000x - Example: 0.75 cents should = 7,500 credits - Bug calculated it as 7.5 credits --- ## 🎯 Code Centralization & DRY ### Unified Cost Calculation - Centralized all cost conversions to use `convertCentsToBillingCredits` utility - Refactored 3 different implementations into 1 single source of truth - Files updated: - `ai-billing.service.ts` - `agent-streaming.service.ts` (2 usages) **Before** (multiple implementations): ```typescript // Wrong implementation const credits = cents * 10; // Verbose implementation const costInDollars = costInCents / 100; const creditsUsed = Math.round(costInDollars * DOLLAR_TO_CREDIT_MULTIPLIER); ``` **After** (unified): ```typescript const creditsUsed = Math.round(convertCentsToBillingCredits(costInCents)); ``` --- ## ✨ UI Component Refactoring ### RoutingDebugDisplay.tsx - **Reduced from 118 lines to 34 lines** (71% reduction) - Extracted `renderTimingRow` helper to eliminate 15 repetitive JSX blocks - Added `formatTokenBreakdown` helper for token display logic - Much easier to add new debug metrics **Before**: 15 nearly-identical blocks of repetitive JSX **After**: Clean, DRY implementation with reusable helpers --- ## 🧹 Code Quality Improvements ### Removed Debug Code - Removed `console.log` accidentally left in `RoutingStatusDisplay.tsx` ### Cleaned Up Comments (18+ removed) Removed redundant comments that stated the obvious: - ❌ "Calculate routing cost if we have token usage" - ❌ "Send the updated routing status with execution metrics to the client" - ❌ "Count tool calls in the response" - ❌ "AI SDK's LanguageModelUsage uses inputTokens/outputTokens" - And 14+ more... Kept meaningful comments: - ✅ "Timing is optional, ignore errors" (explains catch block) - ✅ Type definition grouping comments --- ## 📊 Statistics **Files Modified**: 10 - `convert-cents-to-billing-credits.util.ts` (fixed formula) - `ai-billing.service.ts` (use centralized utility) - `agent-streaming.service.ts` (use utility, remove comments) - `agent-execution.service.ts` (remove comments) - `ai-router.service.ts` (remove comments) - `RoutingStatusDisplay.tsx` (remove debug code) - `RoutingDebugDisplay.tsx` (major refactor) ⭐ - `isDebugModeState.ts` (new file) - `DataMessagePart.ts` (type extensions) - `useClientConfig.ts` (debug mode support) **Impact**: - Lines removed: ~130 (redundant code + comments) - Lines added: ~45 (helper functions) - **Net reduction**: ~85 lines - **Bug fixes**: 1 critical (1000x cost error) - **Centralizations**: 3 locations now using shared utility - **Major refactors**: 1 UI component (71% reduction) --- ## ✅ Verification - ✅ All linter checks pass - ✅ All tests pass (`ai-billing.service.spec.ts` verified) - ✅ No `any` types in affected code - ✅ No TODO/FIXME markers --- ## 🎯 Principles Applied 1. ✅ **Fix Root Causes, Not Symptoms** - Fixed utility function, then used it everywhere 2. ✅ **DRY (Don't Repeat Yourself)** - Centralized cost calculation and UI rendering 3. ✅ **Single Source of Truth** - One place for cost conversion formula 4. ✅ **Code as Documentation** - Removed comments that repeated what code says 5. ✅ **Composability** - Created reusable helper functions 6. ✅ **Type Safety** - Maintained strict typing throughout
