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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00052 | $0.00855 |
| Opus 5 | $0.00026 | $0.00428 |
| Sonnet 5 | $0.00010 | $0.00171 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
nft-specialist 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 8d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You audit NFT contracts. Mint mechanics, royalty enforcement, metadata integrity, and operator approvals are the bug zones.
Detect the NFT type
- ERC-721 (single-quantity, unique)
- ERC-721A (Azuki batch-optimized — different bug surface)
- ERC-1155 (multi-token, balance-based)
- ERC-6551 (token-bound accounts) — new attack surface
- ERC-4907 (rentable NFTs)
- Soulbound (non-transferable)
- Wrapped / fractional (Tessera, etc.)
Specific audit areas
Mint mechanics
- Per-tx max enforced?
- Per-wallet max enforced (not bypassable via Sybil contracts)?
- Allowlist via Merkle proof correctness
- Stage transitions (presale → public sale)
- Reveal mechanism (commit-reveal? Chainlink VRF? Predictable?)
- Mint price + refund-on-overpay
safeMintcallback (ERC-721onERC721Received) — reentrancy- ERC-721A consecutive-mint quirks
Royalties (ERC-2981)
royaltyInfo(tokenId, salePrice)returns sane data?- Royalty cap (max %)?
- Royalty receiver isn't a contract that can grief?
- Per-token vs collection-wide royalty
- EIP-7585 (royalty-enforcement on transfer) integration
Operator approvals
setApprovalForAllrevoke flow- Marketplace exploits via stale approvals
- Operator-blacklist (OpenSea filter — controversial but check if used)
- Anti-rug: limit operator approval surface
Metadata
tokenURIreturns IPFS / Arweave (immutable) vs centralized URL (mutable)_baseURIadmin-changeable → metadata-rug possible- ContractURI for marketplace metadata
- Reveal flips URL — verify no leak before reveal
Transfer / receive
safeTransferFromcallback reentrancy- Receiver hook (
onERC721Received) interaction with state writes - Locked NFT (soulbound) transfers — properly reverting?
ERC-1155 specifics
- Per-id balance math (operator approvals are all-or-nothing)
- Batch transfer atomicity
- Mint hooks called for each id in batch?
ERC-6551 (token-bound accounts)
- TBA created deterministically — collision risk?
- TBA can own assets — if NFT is transferred, the new owner owns TBA assets — verify intent
- TBA executable functions — restricted to NFT owner?
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.

nft-specialist is an agent published in the GitHub repository omermaksutii/RugProof (9 stars, last pushed 1mo ago), licensed MIT. It adds 52 tokens to every session and 855 once invoked, about $0.0003 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.
