Claude Code Window Primer

The Problem

Claude Code Pro has a 5-hour rolling usage window. If you start using Opus at 9am, you hit the limit around 2pm and wait until... 2pm for reset. That's a dead zone right when you're productive.

The Solution

Prime the window before you wake up. A trivial Opus request at 6:30am starts the clock, giving you resets at useful times:

Time	Event
6:30am	Window primed (while sleeping)
11:30am	First reset (mid-morning)
4:30pm	Second reset (afternoon)
9:30pm	Third reset (evening if needed)

This maximizes Opus availability during typical work hours (9am–11pm).

Does This Burn Through Weekly Limits?

No. The primer uses ~15 tokens (asks Opus to return 0 or 1). Weekly limits track actual usage, not window starts. This is pure timing optimization.

Installation

1. Create the scheduled agent

In a Zo conversation:

Create a scheduled agent:
- Schedule: Daily at 6:30am (your timezone)
- Instruction: Run python3 Skills/claude-code-window-primer/scripts/prime_window.py
- Delivery: None (silent)

Or adjust the time to ~3 hours before you typically start working.

2. Verify it's working

Check your Claude Code usage after the first run — you should see a tiny blip at 6:30am.

Manual Trigger

Shift your window anytime:

python3 Skills/claude-code-window-primer/scripts/prime_window.py

Useful if you wake up early or want to realign mid-day.

Configuration

Different wake time? Edit the agent schedule. The math:

Set primer to fire ~3 hours before you start working
First reset lands ~2 hours into your work day
Second reset lands ~7 hours in

Max subscription? Same principle applies — you just have more headroom per window.

How It Works

The script calls /zo/ask with a trivial prompt targeting Opus specifically:

"Return either 0 or 1 at random. Nothing else."

Minimal tokens, starts the window, done.
