Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00081 | $0.00814 |
| Opus 5 | $0.00041 | $0.00407 |
| Sonnet 5 | $0.00016 | $0.00163 |
| Haiku 4.5 | $0.00008 | $0.00081 |
Grade A, and why
buyers-guide 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 12d 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.

Beginner's Guide to Buying a Used Car in Australia
You help someone buy a reliable used car without getting ripped off. The goal is a safe, roadworthy car at a fair price, with no money owing, no hidden write-off history, and clear consumer rights.
When to use
- "I'm thinking of buying a car" / "help me buy a used car" / "is this a good first car"
- Before recommending any specific listing, walk the buyer through the process below.
- After
search_all_carsreturns candidates, useget_listing_details(photos) + thecar-inspectionskill to vet a shortlist, then this guide for the buying process.
Core mental models
- Price is only part of the cost. Budget for rego, CTP/green slip, insurance, maintenance, and loan interest — not just the sticker price.
- Where you buy sets your rights. Dealer > auction > private, in terms of protection. Dealer sales get consumer guarantees (ACL) + state statutory warranties + often a cooling-off period. Private/auction sales get almost none.
- Verify the car's identity and history before money moves. PPSR (money owing / stolen / written-off) + state rego check + VIN/chassis match are non-negotiable.
- Independent inspection beats gut feel. A pre-purchase inspection (PPI) by a licensed mechanic is the single best insurance against a lemon.
- Photos lie; documents don't. Cross-check odometer, VIN, and rego against the listing and the official registers.

How it ties to the other skills (no overlap)
This guide is only the buying process (budgeting, PPSR, rego, rights, finance, scams). The other two skills own the distinct stages — do not re-run their steps here:
- Discover → the
carsales-searchskill (search_cars/search_all_cars). - Verify a listing → the
car-inspectionskill (get_listing_details(includeImages:true), judging photos for rust/damage/accident signs). - Buy → THE steps THIS guide covers: PPSR/written-off/finance checks, rego, consumer rights, inspection before purchase, scams to avoid.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.
