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 | $0.00149 | $0.01684 |
| Opus 5 | $0.00075 | $0.00842 |
| Sonnet 5 | $0.00030 | $0.00337 |
| Haiku 4.5 | $0.00015 | $0.00168 |
Grade A, and why
carsales-search 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.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Carsales Search (discover only)
You are finding used/new cars on carsales.com.au via the carsales-mcp server's
search_cars tool. To get fast, accurate, low-block results, push the filters
carsales itself supports as URL facets into the tool call, and let it do the rest.

carsales' built-in facets (send these to search_cars)
carsales builds the search URL from path segments + query params. Map your filter straight onto the tool's args so the URL carries them server-side:
| Your filter | search_cars arg | notes |
|---|---|---|
| Make | make (required) |
e.g. "Toyota", "Mazda" |
| Model | model |
e.g. "Camry", "CX-5" |
| State | state |
NSW, VIC, QLD, SA, TAS, WA, ACT, NT |
| Body style | bodyStyle |
sedan, wagon, suv, hatch, ute, coupe, van, convertible |
| Transmission | transmission |
automatic, manual |
| Fuel | fuelType |
petrol, diesel, hybrid, electric, plug-in hybrid, lpg |
| Condition | condition |
used, new, private, dealer |
| Keyword | keyword |
free-text (becomes q=) |
| Postcode | postcode |
a carsales location facet |
| Radius | radius (km) |
pairs with postcode, becomes distance= |
| Sort (server token) | sort |
see in-memory note below |
Filters the tool applies IN-MEMORY (no carsales URL facet)
carsales has no URL param for these — the tool fetches a facet URL then filters the cards in memory (and, when a price filter is set, deep-scans a few pages):
- Price →
minPrice/maxPrice(AUD) - Year →
minYear/maxYear - Odometer →
maxOdometer(km) - Sort →
sort=price_low|price_high|year_new|year_old|km_low(applied in-memory by the tool; the tool also sends Carsales a serversort=Odometertoken internally when a price filter is set, to surface old high-km cheap cars).
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.

carsales-search is a skill published in the GitHub repository masked8knights/carsales-mcp (2 stars, last pushed 17d ago), licensed MIT. It adds 149 tokens to every session and 1,684 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
