Problem

The system prompt includes the timezone but not the full date with day of week. This leads to agents frequently getting the day of week wrong when doing calendar/schedule lookups.

Current:

## Current Date & Time
Time zone: America/New_York

Proposed

Include the full formatted date with day of week:

## Current Date & Time
Thursday, February 5, 2026 4:01 PM EST (America/New_York)

Or at minimum:

## Current Date & Time
Thursday, 2026-02-05 16:01 EST (America/New_York)

Why

• Agents (especially Claude) have unreliable mental calendar math
• The day of week is important for schedule context (e.g., "Tuesday is Marketing Day")
• Running date at the start of every session is a workaround but adds latency and token cost

This should be a simple addition to the runtime info injection.
