Help User Set Up Claude Code Window Priming

What This Does

Claude Code Pro/Max plans have a 5-hour rolling usage window. This skill sets up an automated early-morning ping to start that window while you sleep, so resets happen during your productive hours instead of mid-evening.

Example with 6:30am primer:

• 6:30am: Window starts (you're asleep)
• 11:30am: First reset (mid-morning)
• 4:30pm: Second reset (afternoon)
• 9:30pm: Third reset (evening if needed)

Without priming, your first real usage at 9am means resets at 2pm and 7pm — less aligned with typical work patterns.

Step 1: Clarify the Details

Ask the user:

• Wake time: When do they typically start working? (Default: 9am)
• Primer time: Suggest 2.5-3 hours before their wake time for optimal alignment
• Timezone: Confirm their timezone for scheduling

Step 2: Set Up the Automation

Create a scheduled agent that makes a trivial Opus call:

Use tool create_agent with:
- rrule: FREQ=DAILY;BYHOUR=6;BYMINUTE=30 (adjust for their timezone)
- instruction: "Make a single trivial call to Claude Opus: ask it to return either 0 or 1 at random. This starts the 5-hour rolling window. No response needed."
- delivery_method: silent (or "none")

Step 3: Confirm Setup

Tell them:

> Your Claude Code window primer is set for [TIME]. You can test, edit, or delete this automation in the Agents tab. > > How it helps: Your 5-hour windows will now reset at [RESETTIME1] and [RESETTIME2] — better aligned with your work hours.

Key Tips

• Weekly limits unchanged: This only optimizes when resets happen, not total weekly usage
• Minimal cost: Each primer is ~10 tokens — negligible against your usage
• Adjust as needed: If your schedule changes, edit the agent timing

Technical Note

The primer works because Claude Code's rate limit is based on a rolling 5-hour window from your first usage. By making that first usage happen early, subsequent resets align better with active work hours.
