+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Expand Talk to Savings with eight additional read-only AI SDK tools for accounts, categories, recurring transactions, anomalies, uncategorized transactions, period comparison, fixed-cost forecasting, and savings-rate explanations.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Agent registers all eight new read-only tools and returns compact trace summaries without raw/private fields
+- [x] #2 Metadata and data-quality tools return scoped, sanitized accounts, categories, and uncategorized transaction insight
+- [x] #3 Period, savings-rate, recurring, fixed-cost forecast, and anomaly tools compute deterministic aggregates
+- [x] #4 Convex tests cover each new tool and mocked ask() registration
+- [x] #5 Focused tests, targeted lint, build, and full lint status are documented
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add failing coverage for all eight read-only savings insight tools and ask() registry
+2. Implement scoped/sanitized internal Convex queries and deterministic finance helpers
+3. Register the tools in savingsChat.ask and add compact trace summaries
+4. Verify focused tests, targeted lint, build, and document full-lint blockers
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Implemented eight new read-only tools in convex/savingsChat.ts: accounts, categories, recurring patterns, anomalies, uncategorized transactions, period comparison, fixed-cost forecast, and savings-rate explanation.
+Verification: npx vitest convex/savingsChat.test.ts --run --reporter=dot passed (17 tests).
+Verification: npx eslint convex/savingsChat.ts convex/savingsChat.test.ts src/pages/SavingsChatPage.tsx passed.
+Verification: npm run build passed with existing Vite chunk-size warning.
+Full npm run lint still fails on unrelated existing files: convex/bank/comdirectProvider.ts, convex/bank/config.ts, src/components/import/TanAwaitDialog.tsx, several react-refresh only-export-components files, and src/pages/SettingsPage.tsx; warnings also remain in generated Convex files and React Hook Form/TanStack Table locations.
+
+Hardened compare_periods snapshots to omit category IDs while keeping existing summarize_spending output compatible. Re-ran focused Vitest, targeted ESLint, and build successfully after this change.
