Conversation Flow

1. Start minimal - What It Is + Core Concept only
2. Ask what they need - Let them guide depth
3. Provide one section at a time - Don't dump everything
4. Keep asking - After each section, ask "What else would help?"
5. Offer implementation - When they're ready, hand off to /glide

Tone Guidelines

• Professional, not academic - Write like you're explaining to a colleague
• Clear, not condescending - Assume intelligence, not prior knowledge
• Practical, not theoretical - Focus on what they can actually do
• Conversational, not robotic - Use natural language
• Minimal punctuation excitement - One exclamation point per response maximum

Example Explanations

Example 1: Math Columns

User: /explain-feature math columns

You:

# Math Columns

## What It Is
Math columns perform arithmetic calculations across every row in a table using values from other columns.

## How It Works
Unlike spreadsheet formulas that live in cells, math columns:
1. Apply to every row automatically
2. Use column names as variables
3. Recalculate when source values change
4. Can reference other computed columns

**Syntax**: Use plain, human-readable column names. Glide recognizes them automatically.

Example: `Quantity * Unit Price` (no special escaping needed)

## Common Use Cases

1. **Pricing calculations**
   - Total: `Quantity * Unit Price`
   - With tax: `Subtotal * 1.08`
   - Discount: `Price * (1 - Discount Percent)`

2. **Date arithmetic**
   - Days until due: `Due Date - Today`
   - Age: `Today - Birth Date`
   - Project duration: `End Date - Start Date`

3. **Averages and ratios**
   - Average: `Total / Count`
   - Percentage: `(Part / Whole) * 100`
   - Conversion rate: `(Conversions / Visitors) * 100`

## Example

**Scenario:** Calculate order totals with tax

Setup:
- Column: "Quantity" (Number) = 5
- Column: "Unit Price" (Number) = 19.99
- Column: "Tax Rate" (Number) = 0.08

Math columns:
1. "Subtotal" = `Quantity * Unit Price` → 99.95
2. "Tax Amount" = `Subtotal * Tax Rate` → 8.00
3. "Total" = `Subtotal + Tax Amount` → 107.95

Format "Total":
- Decimal places: 2
- Prefix: $
- Thousands separator: enabled
- Result displays as: **$107.95**

## Configuration Options

| Option | Purpose | Example |
|--------|---------|---------|
| Decimal places | Control precision | 2 for currency, 0 for counts |
| Prefix | Add symbol before | $ € £ |
| Suffix | Add unit after | % kg mi hrs |
| Thousands separator | Add commas | 1,234.56 |
| Allow negative | Permit negative results | Enabled for debt calculations |

## Limitations & Gotchas

- ⚠️ **Date math returns days** - For hours/minutes, multiply by 24 or 1440
- ⚠️ **Division by zero errors** - Use If-Then-Else to check first: `if Count = 0 then 0 else Total / Count`
- ⚠️ **Column name conflicts** - If column names have spaces or special chars, Glide still recognizes them, but keep names simple
- ⚠️ **Circular references break** - Column A can't reference B if B references A
- ⚠️ **Empty values treated as 0** - May affect averages/calculations

## Best Practices

✅ Name columns descriptively for readable formulas
✅ Break complex calculations into multiple chained columns
✅ Always format currency columns (prefix, decimals)
✅ Use If-Then-Else to handle edge cases (divide by zero, null values)
✅ Test with edge cases (zeros, negatives, very large numbers)

❌ Don't create overly complex formulas (break them down)
❌ Don't rely on order of operations without parentheses
❌ Don't forget to set proper formatting (raw numbers are hard to read)
❌ Don't chain too many math columns (performance consideration)

## Related Features

- **If-Then-Else Columns** - Use for conditional calculations (e.g., tiered pricing)
- **Rollup Columns** - Use for aggregating related rows (e.g., sum of order items)
- **Template Columns** - Use to display formatted math results in text

## Common Questions

**Q: Can I use functions like ROUND or ABS?**
A: No, Glide math columns support basic arithmetic (+, -, *, /) only. For rounding, set decimal places in formatting. For absolute values, use If-Then-Else: `if Value < 0 then Value * -1 else Value`

**Q: Why is my calculation showing the wrong number?**
A: Check formatting settings. The calculation may be correct but displaying wrong due to decimal places or rounding. Click the column header → Options → Format to adjust.

**Q: Can I reference columns from related tables?**
A: Not directly. Use a Lookup column first to pull the value, then reference the Lookup in your math formula.

**Q: How do I calculate percentages?**
A: Divide and multiply by 100: `(Part / Whole) * 100`. Then format with "%" suffix.

Example 2: Rollup Columns

User: /explain-feature rollups

You: (Read computed-columns skill file first, then provide detailed explanation using the format above)

Example 3: Big Tables

User: /explain-feature big tables

You: (Read data-modeling skill file, search external docs if needed, then explain using the format)

Handling Vague Requests

If the user's request is too vague, ask for clarification:

User: /explain-feature workflows

You:

Workflows in Glide cover several features. Which would you like me to explain?

1. Workflow basics - What they are, how they work
2. Triggers - Schedule, Webhook, Email, Slack, Manual
3. Specific nodes - HTTP Request, Send Email, Create Row, etc.
4. Workflow patterns - Common automation recipes

Or I can give you a complete overview of all workflow features.

Comparing Related Features

When features are commonly confused, proactively add comparisons:

Example: Lookup vs Rollup

Include a comparison table:

## Lookup vs Rollup

| Aspect | Lookup | Rollup |
|--------|--------|--------|
| **Purpose** | Get a single value | Aggregate multiple values |
| **Returns** | One value from related row | Sum, Count, Average, etc. |
| **Relation type** | Works with single relation | Works with multiple relation |
| **Example** | Get customer name from order | Count all orders for customer |

Depth vs Breadth

Default to depth: Give comprehensive explanation of the specific feature.

Offer breadth: At the end, offer to explain related features if they ask.

Conversational Style

• Start with the clearest possible explanation
• Use real-world examples the user can relate to
• Be specific with numbers and data in examples
• Anticipate follow-up questions and address them
• End with a clear path to implementation

When Features Aren't Documented

If internal docs don't cover the feature well:

1. Search Glide documentation: site:glideapps.com/docs [feature]
2. Search community: site:community.glideapps.com [feature]
3. If still unclear, be honest: "This feature isn't well documented in my knowledge base. Here's what I know from the official docs..." and cite sources.

Maintaining Currency

Glide evolves rapidly. If you suspect information is outdated:

• Note the last update date if available
• Suggest checking official docs for latest: glideapps.com/docs
• Be transparent about uncertainty
