Best Hydrogen Prompts For Work-Pattern Analysis
Hydrogen gets better fast when the prompt includes a time window, a comparison target, and a clear metric or question type.

Takeaway 1
Prompt quality improves more from structure than from length.Takeaway 2
A time window and a comparison target are usually enough.Takeaway 3
Loose prompts force Hydrogen to spend time narrowing the scope for you.1
What good prompts usually include
The best prompts are narrow enough to compare something real and broad enough to leave room for interpretation.
Time window
Required
Hydrogen needs scope before analysis.
Comparison
Better
Compare periods instead of asking for a vague summary.
Output style
Clear
Ask for summary, likely driver, or next step.
Prompt formula
Time window + comparison target + metric/theme + output style is usually enough.
A time window
A comparison target
One or two metrics or themes
A clear output style such as summary, pattern, or likely driver

Three prompt templates worth reusing
You do not need a long prompt. You need a prompt with a stable frame.
Sample prompt quality by structure
Illustrative score for how much useful context the prompt gives Hydrogen.
Sample data
Compare my fatigue and active minutes over the last 14 days versus the previous 14.
Summarize my strongest work-pattern shift this week and explain what probably changed.
Show my lowest-energy window on workdays and tell me whether it repeats.

What to avoid
Prompts like "How am I doing?" or "Tell me everything about my fatigue" force the system to ask follow-up questions because the scope is too loose.
Avoid vague prompts
Replace How am I doing? with Compare my last 14 days against the previous 14 and show the strongest repeated work-pattern shift.
