Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ppi-scheduler scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPI Scheduler

Caveat: this skill is one author's playbook + 5-scenario stress test. Verify state fees / CPO terms / EV credits / dealer practices against current sources before quoting numbers to a dealer or making financial decisions. Not tax, legal, or financial advice. last_verified: 2026-05-18 (Phase 3C sub-skill split from orchestrator)

Narrow helper: book a mobile PPI on one or more final candidates before signing. Defers the full inspector directory + form-field gotchas to ../orchestrator/references/ppi_booking.md.

When To Use

  • Buyer has 1-4 used-car final candidates and wants mechanical sign-off
  • Buyer asks for a mobile inspector recommendation by region
  • Need PARALLEL booking strategy across 2-4 dealers same day
  • Need brand-specific PPI scope (Subaru CVT, Toyota hybrid, etc.)
  • Post-PPI walk vs proceed decision

When NOT To Use

  • New car off the truck under factory bumper-to-bumper - PPI is rarely cost-justified; skip
  • CARFAX history review only (no mechanical) - delegate to carfax-pdf-review
  • General CPO benefits eligibility - delegate to cpo-eligibility

Mobile PPI Services by Region

Region Service Price Notes
NY / NJ / CT Lemon Protector $139+ lemonprotector.com, dispatched tri-state
CA / Bay Area YourMechanic $150-200 App-based, ASE-certified
CA / SoCal Lemon Squad $175 Mobile, fast scheduling
Multi-state Pep Boys Mobile $150 Variable quality by region
Multi-state Carchex Mobile Inspection $190 Insurance-grade reports
Local fallback Yelp top-rated ASE shop $100-200 Best for brand specialists

For Subaru / Toyota / Honda hybrid powertrains: prefer brand-specialist shop over generic mobile when one is within 15 miles. Specialists catch CVT seepage, head gasket weep, inverter coolant level that generic miss.

Parallel Booking Strategy (2-4 Candidates Same Day)

Per orchestrator gotcha P1: when there are 2-4 final candidates and the buyer plans to commit within 24-48 hours, stagger PPIs on a SINGLE day to compress the decision window.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
