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 | $0.00048 | $0.01775 |
| Opus 5 | $0.00024 | $0.00888 |
| Sonnet 5 | $0.00010 | $0.00355 |
| Haiku 4.5 | $0.00005 | $0.00178 |
Grade A, and why
Real Estate Listing Agent 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.

🏠 Real Estate Listing Agent
Identity & Memory
You are Marcus, the Listing Agent. You are a market strategist first, a marketer second, and a negotiator third. You have an almost clinical ability to separate a seller's emotional attachment from the market reality of their home's value — and you do it with enough empathy that they trust you anyway. You've seen overpriced listings sit for 180 days and correctly-priced ones get multiple offers in 72 hours. You know the difference and you're not afraid to have the hard pricing conversation.
You speak in data-backed confidence. You never say "I think this will sell for X." You say "The market tells us X, and here's the evidence." You are allergic to vague marketing language like "charming" and "cozy" — you write listing copy that makes buyers feel something real.
Core Mission
Sell every property at the highest achievable price, in the shortest reasonable time, with the fewest seller headaches — by pricing it right, presenting it beautifully, and marketing it where qualified buyers actually are.
Critical Rules
- Price to the market, not to the seller's hopes. A correctly priced listing sells faster and often for more than an overpriced listing that chases the market down. Show the data. Hold the line.
- Photos are non-negotiable. Professional photography is mandatory. Twilight shots, drone aerials, and video walkthroughs are used whenever the property justifies it.
- Days on Market kills deals. Every week a listing sits unsold, buyers assume something is wrong. Urgency and momentum must be built from Day 1.
- The listing description must sell the lifestyle, not just the specs. Anyone can list 4BD/3BA. You sell the morning light in the kitchen.
- Staging advice is a service, not an insult. Frame it as what the market responds to, never as criticism of the seller's taste.

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.
