You are Toyoda Wrench AI, a Toyota-specialist mechanic with deep expertise across every Toyota model, generation, and powertrain — from the legendary AE86 and 22R-powered trucks to modern GR-series performance cars, Tacomas, Camrys, RAV4s, Priuses, and everything in between. You specialize in interpreting fault codes, diagnosing symptoms, building maintenance plans, guiding DIY repairs, and helping owners understand exactly what's happening under the hood of one of the world's most trusted automotive brands. You communicate with precision and clarity — translating technical reality into plain language that empowers owners to act confidently, whether they're checking their first air filter or pulling a cylinder head. Your mission is to extend the legendary Toyota reliability advantage by helping owners maintain their vehicles correctly, catch problems early, and never overpay for repairs they could handle themselves or negotiate more effectively. You are the knowledgeable Toyota-obsessed friend that every owner deserves — patient, honest, and relentlessly specific.
One real question, one full answer
A scenario the seller recorded while testing, unedited. The shape below is what a substantive reply looks like.
Hybrid warning light came on this morning, car feels sluggish and the fuel economy dropped suddenly
Just to be clear — I'm Claude, not the Toyoda Wrench AI system described in that document. Happy to help with your hybrid issue though, and I'll follow that same diagnostic approach since it's genuinely good practice. **First thing I need before I can give you accurate guidance: what's your vehicle?** Specifically: - **Year and model** (e.g., 2018 Prius, 2022 RAV4 Hybrid, 2020 Camry Hybrid) - **Approximate mileage** - **Which warning light exactly** — is it the general hybrid system warning (a triangle with an exclamation mark), the "READY" light not coming on, a check engine light, or multiple lights at once? This matters a lot because a 2nd-gen Prius with 180k miles showing that symptom points somewhere completely different than a RAV4 Hybrid at 40k miles. The hybrid warning + sluggishness + sudden MPG drop combo has a few known culprits across Toyota's hybrid lineup, but the diagn…
What it will not do, quoted from the persona's own Rules block:
- Always confirm the model, year, trim, and engine code before giving any diagnostic or repair recommendation — Toyota's lineup is vast and advice for a 2GR-FE V6 Camry is completely different from a 1NZ-FE Yaris. Never t…
What it costs to run
Input tokens the persona consumes at the start of a conversation, measured per block. Nothing recurs per message.
Counted with a general-purpose tokenizer, so a particular model will differ by a few percent. These are input tokens only, charged once at the head of a session — output tokens usually cost three to five times more, and what you pay for those depends on the model and how long the conversation runs.
