The Problem
You just spent 10 minutes crafting the perfect prompt. It worked beautifully.
Next week, you need something similar. Where did you save that prompt? You didn't.
So you start from scratch. Again. And again. And again.
The waste: You're solving the same problem repeatedly instead of building on what works.
The solution: A prompt library. Systematic. Organized. Reusable.
What Is a Prompt Library?
A collection of proven prompts organized by task.
Not a random document of things you tried once. A curated library of what actually works.
✓ Think of it like
- A recipe box (tested recipes you return to)
- A style guide (standards you reference)
- A template library (starting points you customize)
✓ What it contains
- Prompts that consistently produce good results
- Notes on when to use each one
- Versions as you improve them
- Context about why they work
✗ What it doesn't contain
- Every prompt you've ever tried
- Experiments that didn't work
- One-off prompts for unique situations
Why You Need One
| Without a library | With a library |
|---|---|
| Start from scratch every time | Copy, customize, run (30 seconds) |
| Forget what worked last time | Build on past successes |
| Waste time re-solving solved problems | Focus time on new challenges |
| Inconsistent quality across projects | Consistent quality every time |
💡 The compounding effect
Each prompt you save makes future work faster. After 6 months, you have templates for 80% of your common tasks.
How to Organize Your Library
Simple structure that scales.
Option 1: By task type
Option 2: By project phase
Option 3: By audience level
💡 The rule: Pick what matches your workflow. Don't overthink it. Start simple. Reorganize later if needed.
What to Include in Each Entry
Every prompt in your library should have:
| Element | What it is | Example |
|---|---|---|
| Prompt text | The actual prompt | "Create a learning objective for [topic]..." |
| Use case | When to use this | "Use for technical training with measurable outcomes" |
| Variables | What to customize | [topic], [audience], [context] |
| Example output | What good looks like | "By the end of this module, technicians will..." |
| Version | Track improvements | "v2.1 - Added Bloom's verb requirement" |
| Success rate | How often it works | "Works 8/10 times without refinement" |
Minimal version (if you're in a hurry): Just save the prompt text and use case. You can add the rest later.
Template Patterns for Common Tasks
Here are starter prompts to add to your library. Customize for your context.
Learning Objectives
Variables to customize: [topic], [audience], [context]
Scenario Development
Variables to customize: [topic], [role/level], [workplace environment], [problem], [skill]
Assessment Questions (Multiple Choice)
Variables to customize: [learning objective]
Versioning Your Prompts
Prompts improve over time. Track that.
Version numbering system:
- v1.0 - First working version
- v1.1 - Minor refinement (added detail, clarified wording)
- v2.0 - Major change (new requirement, different approach)
Example evolution:
"Create a learning objective for customer service training."
"Create a learning objective for customer service training. Use a measurable action verb. Focus on de-escalation skills."
"Create a learning objective for [topic] training aimed at [audience]. Requirements: Use a measurable action verb from Bloom's taxonomy. Include the context: [specific situation]. Focus on performance, not just knowledge. Output only the objective."
What to note when you update:
- Date of change
- What you changed
- Why you changed it
- Success rate before vs. after
When to Add a Prompt to Your Library
Not every prompt belongs in your library.
| Add it if... | Don't add if... |
|---|---|
| ✓ You'll use this type of prompt again | ✗ One-off for a unique situation |
| ✓ It consistently produces good results (80%+ success rate) | ✗ Experimental—not sure if it works yet |
| ✓ You spent time refining it to work well | ✗ Produces inconsistent results |
| ✓ Others on your team could use it | ✗ Too specific to be reusable |
💡 The test
If you'd want this prompt available next week, save it now.
Starting Your Library Today
Don't wait for the perfect system. Start now.
| When | What to do | Time |
|---|---|---|
| Day 1 | Create structure: folder/doc with 3-5 category headers | 5 min |
| Week 1 | Add your 3-5 most-used prompts with use cases | 15 min |
| Month 1 | Refine as you use; save improved versions | Ongoing |
| Month 6 | You have 15-20 proven prompts; 80% coverage | Done |
Key Takeaways
- Stop starting from scratch. A prompt library compounds—each saved prompt makes future work faster.
- Start simple, build gradually. 5 minutes to create structure, 15 minutes to add first prompts.
- Track versions. Prompts improve over time—document what changed and why.
- Only save proven prompts. 80%+ success rate = worth keeping. Experiments stay out until they work consistently.
