Core Rules

1. Always Compare Multiple Sources

Never recommend based on one site. Check at least 3 sources:

• - Aggregators: Kayak, Google Flights, Rentalcars.com
• Direct: Hertz, Avis, Enterprise, Sixt, Europcar
• Budget: AutoEurope, DiscoverCars, local options

2. Factor Total Cost

Base price is misleading. Always calculate:

• - Insurance (CDW, theft, liability)
• Fuel policy (full-to-full vs prepaid)
• Airport fees and taxes
• Mileage limits and overage charges
• One-way drop-off fees
• Young/senior driver surcharges

3. Track User Preferences

Save and apply:

• - Preferred car class (economy, SUV, luxury)
• Insurance preferences (own coverage vs rental)
• Transmission preference (auto vs manual)
• Fuel type (petrol, diesel, electric, hybrid)
• Loyalty programs (Hertz Gold, Avis Preferred, etc.)

4. Monitor With Permission

When user explicitly requests an alert:

• - Ask how often they want updates
• Check prices at requested intervals
• Notify on significant drops (>15%)
• Track availability for high-demand dates
• User can disable alerts anytime

5. Match Solution to Duration

Duration	Best Option
1-7 days	Standard rental
1-4 weeks

Long-term rental or subscription |

| 1-6 months | Lease or subscription | | 6+ months | Lease, finance, or buy |

6. Location Intelligence

Prices vary dramatically by:

• - Airport vs city center (airport often 30-50% more)
• Country regulations (some require IDP)
• Local vs international companies
• Seasonal demand (holidays, events)

Car Rental Traps

• - Prepaid fuel trap → Often overpriced. Full-to-full policy is usually cheaper unless you genuinely cannot refuel before return.
• Basic insurance trap → CDW often has high excess (€1000+). Check if your credit card or travel insurance covers this.
• One-way fee surprise → Can be €100-500+. Always check before booking if picking up and dropping off in different locations.
• Manual transmission default → In Europe, cheapest options are often manual. Filter for automatic if needed.
• Mileage caps → Some "cheap" deals have 100km/day limits. Calculate your actual needs.
• Credit card hold trap → Some companies block €1000-3000 on your card. Debit cards often refused.

Comparison Framework

Rent vs Lease vs Buy

Factor	Short Rental	Long-term Lease	Buy
Duration	Days to weeks	Months to years	Permanent
Upfront cost

Low | Medium | High | | Monthly cost | Highest | Medium | Lowest (once paid) | | Flexibility | Maximum | Medium | Low | | Maintenance | Included | Usually included | Your responsibility | | Best for | Travel, occasional use | Temporary relocation, testing | Permanent need |

When to Consider Leasing

• - Relocating 3-12 months
• Testing a car before buying
• Don't want maintenance hassle
• Business use with tax benefits
• Credit score issues (easier than financing)

When Short-term Rental Beats Leasing

• - Less than 2-3 months total use
• Sporadic use (weekends only)
• Different car needs each time
• Peak season (leasing harder to find)

Alert Configuration

Users can set alerts for:

• - Price drop — Notify when price falls below threshold
• Availability — Notify when specific car becomes available
• Deal quality — Notify when total cost is in bottom 20% historically
• Comparison — Notify when better option found vs current booking

Alert frequency options:

• - Immediate (any change)
• Daily digest
• Weekly summary

Data Storage

All data is stored locally in ~/car-rental/ (created only with your permission):

• - memory.md — your preferences and active alerts
• searches/ — saved search configurations
• history/ — past rental price snapshots

You control everything:

• - View: Read any file in ~/car-rental/
• Delete: Remove files or the entire folder anytime
• No cloud sync, no external storage

Security & Privacy

Data that stays local:

• - All preferences and search history in ~/car-rental/
• No telemetry or cloud sync

When comparing prices:

• - Agent searches rental sites using your specified criteria (location, dates, car type)
• These search parameters are sent to rental sites (Kayak, Hertz, etc.) as part of normal searches
• No account credentials, payment info, or personal identifiers are shared

This skill does NOT:

• - Store payment information
• Make bookings on your behalf
• Access files outside ~/car-rental/
• Send data to any server we control
