+DEVIATION: Tool Files Use Vanilla JavaScript (.js)
 ================================================================================
+Reasoning: Standalone utility tools (screen-capture, screen-record, user-alert)
+  designed as reusable browser-side modules. Vanilla JS allows direct browser
+  execution without build step. Tools are self-contained utilities, not critical
+  business logic. Conversion to TypeScript not necessary at current maturity.
+Affected Files:
+  - /tools/screen-capture/index.js (246 LOC)
+  - /tools/screen-record/index.js (165 LOC)
+  - /tools/user-alert/index.js (196 LOC)
+Implications:
+  - Loss of type safety on tool internals (no IDE autocomplete, no .ts checks)
+  - Tools cannot be used in strict TypeScript environments without @ts-ignore
+  - Maintenance slightly harder as tool complexity grows
+Standards Violated:
+  - LANGUAGE: TypeScript (Frontend & Backend) → Using vanilla JS instead
+Adopted: 2026-01-14
+Review Date: 2026-03-01
+Triggers for Conversion:
+  - Tools grow beyond 250 LOC each
+  - Tools need to interact with backend types
+  - Tool suite grows to >5 tools
+  - Performance optimization requires bundling
