… day Without weekday in the formatted timestamp, the agent had to infer the day of the week from its training knowledge and sometimes got it wrong (e.g. treating Monday as Sunday). Adding weekday: 'long' makes the day explicit in every message context passed to the container. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Type of Change
.claude/skills/Description
formatLocalTime in src/timezone.ts produced timestamps like Mar 9,
2026, 11:59 AM with no weekday. The agent had to infer the day of the week
from the date string alone, and LLMs are unreliable at computing calendar
weekdays for arbitrary dates.
Changes
Added weekday: 'long' to the Intl.DateTimeFormat options in formatLocalTime,
so the output now includes the full weekday name
Updated src/timezone.test.ts to assert the weekday name is present in the
output.
Test plan
npx vitest run src/timezone.test.ts)npm run build)identifies the day of the week without inference errors
