REPLACING LLM DATE MATH WITH DETERMINISTIC SCRIPTS TO IMPROVE CALENDAR ACCURACY
Summary from the TLDR Dev newsletter
LLMs like Claude frequently fail at date math, causing calendar errors in tools like gcalcli. Offloading calculations to deterministic scripts ensures accuracy. Developers can eliminate hallucinations and create reliable, repeatable AI workflows by updating CLAUDE.md instructions to execute code instead of manual reasoning.
