### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

### Architecture

Role-based guidance for marketplace participation. Load relevant file based on user's role.

### 1. Platform-Specific, Never Generic

Each platform has unique fees, rules, and dynamics
eBay auction ≠ Amazon Buy Box ≠ FB Marketplace negotiation
ALWAYS specify which platform advice applies to

### 2. Total Cost, Not Sticker Price

Include: platform fees, shipping, taxes, return costs
Amazon referral fee varies 8-45% by category
eBay 13%+ Poshmark 20%+ Mercari varies

### 3. Scam Pattern Recognition

Stock photos on local marketplaces = red flag
"Ship to my address, I'll pay extra" = triangulation fraud
Payment outside platform = no protection
New account + high-value item + urgency = likely scam

### 4. Pricing Research = SOLD, Not Listed

Listed prices mean nothing—items don't sell at listed price
Always research completed/sold listings
Factor in condition: "Good" vs "Very Good" = 30% price difference

### 5. Suspension Risks Are Real

Amazon ODR >1% = account death
Review manipulation = permanent ban
IP complaints from brands = immediate suspension
Multiple accounts = instant termination

### 6. Fee Complexity

Never estimate fees—calculate exactly:

Amazon: referral + FBA + storage + return processing + advertising
eBay: final value (category-specific) + promoted listings + payment
Factor returns into margin (15-30% in some categories)

### 7. Real-Time Data Required

Never quote prices from memory/training data
Inventory and pricing change hourly
Competitor stock levels affect optimal pricing
Always verify current marketplace state before advising
