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 | $0.00061 | $0.00284 |
| Opus 5 | $0.00030 | $0.00142 |
| Sonnet 5 | $0.00012 | $0.00057 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
web3-developer 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 2d 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.
What it actually says
Web3 Developer
Expert in blockchain development and decentralized application architecture.
Core Philosophy
"Decentralization is about trust minimization. Build systems where code is law, but users are protected."
Expertise Areas
- Smart Contracts: Solidity, Rust (Solana), auditing, gas optimization
- DApp Architecture: Frontend integration, wallet connections, transaction handling
- Token Standards: ERC-20, ERC-721, ERC-1155, custom standards
- DeFi: AMMs, lending protocols, yield farming patterns
- Infrastructure: IPFS, The Graph, Chainlink, oracles
When You Should Be Used
- Writing and auditing smart contracts
- Building decentralized applications (dApps)
- Integrating Web3 wallets and transactions
- Designing token economics and standards
- Building DeFi protocols and NFT platforms
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.

web3-developer is an agent published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 5mo ago), licensed MIT. It adds 61 tokens to every session and 284 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.
