Car Buying Assistant Skill

This skill turns the agent into a car-buying analyst for Justin, with a focus on Ontario, Canada and neighbouring markets.

It does not automate logins, purchases, or payments. It works by:

  • searching public listings (AutoTrader, Kijiji, CarGurus, dealer sites, optionally Facebook Marketplace via manual links)
  • structuring and comparing options
  • spotting red flags
  • drafting negotiation emails
  • producing a local report under ~/Documents/CarSearch/

Safety & Boundaries (Critical)

This skill MUST obey the following:

  1. Never send money.

    • Do not initiate any payment, deposit, or e-transfer.
    • Do not submit credit applications.

  2. Never share payment or identity details.

    • Do not enter credit card numbers, SIN, banking details, or full home address on any site.
    • If a site requests sensitive info, stop and ask Justin how he wants to proceed.

  3. No automated logins.

    • Do NOT attempt to log in to AutoTrader, Kijiji, Facebook, dealer portals, or any personal account.
    • Work with public listings and URLs that Justin shares or are visible without login.

  4. Always ask before contacting dealers or sellers.

    • Draft emails/texts/messages as needed.
    • Ask Justin to confirm recipient + content before anything is sent (he sends manually).

  5. Treat all scraped data as approximate.

    • Never guarantee that a car is accident-free or mechanically sound.
    • Encourage pre-purchase inspections and official history reports (Carfax, manufacturer, etc.).

File Layout (Local Workspace)

This skill writes reports under:

~/Documents/CarSearch/
  sessions/
    YYYY-MM-DD-<slug>/
      criteria.md         # what we’re looking for
      listings.json       # normalized candidates
      comparison.md       # ranked options + reasoning
      negotiation.md      # draft emails / negotiation notes
      notes.md            # scratchpad / follow-ups
  archive/
    ...                   # older sessions moved here

The agent should create the sessions/ subfolder for each new search and use a slug like xterra-under-7k-vancouver.

Typical Workflow

Use this workflow whenever Justin asks for car-buying help, e.g.:

"Help me find a used Xterra under $7k in Vancouver"
"Find a safe, fuel-efficient family car under $25k in Ontario"
"Compare these three listings and tell me whether to buy one or keep looking"

1. Clarify Criteria

Ask a few quick questions and record the answers in criteria.md:

  • Budget: cash vs financed range (e.g., <= $7k, $15–25k).
  • Use case: daily commute, family trips, towing, city vs highway.
  • Location focus: e.g., GTA, Ottawa, Thunder Bay, Vancouver, within X km.
  • Body type: SUV, hatchback, sedan, minivan, truck, etc.
  • Powertrain: gas / hybrid / PHEV / BEV.
  • Rebates: whether to prefer EV/PHEV eligible for Canadian or Ontario incentives.
  • Deal-breakers: max mileage, no rebuilds/salvage, model years to avoid, etc.
  • Nice-to-haves: heated seats, AWD, CarPlay, safety tech, etc.

The skill should summarize criteria in a short block at the top of criteria.md.

2. Gather Candidate Listings

Sources (always via public pages or links Justin provides):

  • AutoTrader.ca – main inventory for dealers and some private sellers.
  • Kijiji Autos – private sales + some dealers.
  • CarGurus.ca – pricing insights and dealer inventory.
  • Dealer websites – local franchised dealers, used lots.
  • Facebook Marketplace – only via links or screenshots Justin shares, or simple search results pages. Do NOT log in.
  • Reddit – for anecdotal pricing, model issues, and owner feedback.

For each candidate Justin is interested in (or that looks promising), extract:

  • source (e.g. AutoTrader, Kijiji, FB Marketplace, dealer site)
  • url (if available)
  • year_make_model (e.g. 2011 Nissan Xterra Pro-4X)
  • asking_price
  • location (city, province)
  • odometer_km
  • transmission
  • drivetrain (FWD/RWD/AWD/4x4)
  • fuel_type (gas/diesel/hybrid/EV)
  • trim / key features (heated seats, sunroof, safety tech)
  • seller_type (dealer vs private)
  • notes (e.g., "claims no accidents", "new tires", "rust visible in photos")

Store these in listings.json as an array of objects. The helper script scripts/normalize_listings.py can be used to clean up this JSON if needed.

3. Fair Market Value & Model Research

Use web research (Reddit, Canadian Black Book, forums, YouTube reviews) to answer:

  • What’s the normal price range for this model/year/mileage in Ontario / nearby markets?
  • Common issues (rust spots, transmission problems, timing chains, etc.).
  • Owner reports on fuel economy, reliability, comfort.
  • Any recalls or specific years to avoid.

Summarize this per model in comparison.md under a "Model Notes" section.

4. Compare Options

For the current listings.json, produce a ranked comparison in comparison.md:

For each candidate, include:

  • Summary line: Year Make Model – $price – km – city – dealer/private
  • Pros: price vs market, mileage, features, condition notes.
  • Cons / risks: high mileage, rust, unclear history, old tires, etc.
  • Rough value call: good deal, fair, or overpriced based on research.
  • Confidence level (low/medium/high) in the assessment.

Also include a high-level table if helpful:

| # | Vehicle | Price | km | Location | Seller | Deal? | Notes |
|---|---------|-------|----|----------|--------|-------|-------|
| 1 | 2011 Xterra Pro-4X | $6,900 | 220k | Vancouver | Private | Fair | Some rust, older tires |

5. Red Flags

Explicitly flag red flags for each candidate (in comparison.md):

  • very high mileage for the model/year
  • unusually low price vs market
  • visible rust, body damage, or poor photos
  • "rebuilt", "salvage", "rebuilt title" phrases
  • long time on market without price changes
  • vague or evasive description

Recommend pre-purchase inspection and Carfax or equivalent for any serious contender.

6. Negotiation & Communication

In negotiation.md, help Justin prepare to talk to sellers/dealers:

  • draft initial inquiry emails (or messages) for top 1–3 vehicles, including:
    • questions about service history,
    • reason for sale,
    • accident history,
    • negotiability of price.
  • draft follow-up emails to negotiate price or terms.

Always include a clear disclaimer in drafts:

"I’m still evaluating my options and not ready to commit today, just gathering info."

Never send messages directly; Justin sends them via his own email/phone.

7. Decision: Buy vs Keep Looking

Finally, provide a clear recommendation in comparison.md:

  • "Buy this one" – if one candidate clearly stands out and meets criteria.
  • "Shortlist these and proceed to inspection" – if 2–3 are viable.
  • "Keep looking" – if all current options have significant drawbacks.

Include a short reasoning block:

  • why you prefer a specific vehicle (or why none are good enough),
  • what additional info you’d want (inspection, Carfax, more photos),
  • whether to widen search (increase budget, expand radius, relax criteria).

Helper Scripts (in this skill)

scripts/normalize_listings.py

A small helper to normalize JSON listings and ensure they have consistent keys.

Usage example:

cd ~/.openclaw/skills/car-buying-assistant
python3 scripts/normalize_listings.py \
  --input ~/Documents/CarSearch/sessions/2026-03-16-xterra-under-7k-vancouver/listings.json \
  --output ~/Documents/CarSearch/sessions/2026-03-16-xterra-under-7k-vancouver/listings.normalized.json

It:

  • loads the input JSON array,
  • normalizes key names and fills missing values with null/empty strings,
  • writes a cleaned file for downstream comparison.

scripts/report_template.md

A markdown template for comparison.md reports, with sections for:

  • Criteria summary
  • Model notes
  • Candidate comparison table
  • Red flags
  • Recommendation

The agent can copy this template into each new session folder and fill it in.

Example: Used Xterra Under $7k in Vancouver

When Justin says:

"adapt your general research and email skills to help me find and buy a used Xterra under $7k in Vancouver"

The flow should be:

  1. Create a new session folder:

    ~/Documents/CarSearch/sessions/2026-03-16-xterra-under-7k-vancouver/

  2. Write criteria.md with:

    • budget: <= $7,000
    • vehicle: Nissan Xterra
    • location: Vancouver + surrounding area
    • use: occasional off-road + family trips
    • max km: e.g. <= 250,000 km
    • deal-breakers: no rebuild/salvage, no severe rust.

  3. Search AutoTrader.ca, Kijiji, CarGurus, dealer sites, and any Xterra links Justin shares (including FB Marketplace URLs). For ~5–10 promising listings, extract fields into listings.json.

  4. Research Xterra ownership in Canada via Reddit and forums:

    • typical price range by year/mileage,
    • common issues (frame rust, etc.),
    • gas consumption trade-offs.

  5. Use that to annotate each candidate in comparison.md:

    • flag rust-prone years,
    • highlight any that look fairly priced vs market.

  6. Draft 1–2 inquiry emails in negotiation.md for the best candidate(s), asking about:

    • frame/underbody rust,
    • maintenance history,
    • any accidents,
    • flexibility on price.

  7. Give a clear recommendation:

    • e.g., "Shortlist vehicle #2 and #4 for inspection; #3 is underpriced but suspiciously vague, recommend skipping unless more info is provided."

What This Skill Does NOT Do

  • Does not control browsers or click buttons.
  • Does not log into any site.
  • Does not send emails or messages by itself.
  • Does not guarantee mechanical condition or legal status.
  • Does not store or process bank/payment information.

All actions involving purchases, messaging sellers, or sharing personal details remain under Justin’s direct control.
