blockchain-contract-attack

blockchain-contract-attack is a skill for Claude Code, Codex from Ed1s0nZ/CyberStrikeAI. It costs 59 tokens per session (283 once invoked), scanned A, original, Apache-2.0.

Postupy na kontrolu blockchainov a inteligentných zmlúv, čo sú programy, ktoré automaticky vykonávajú pravidlá transakcií.

In plain words
What is it for?
Pomáhajú analyzovať zdrojový kód, kontrolovať opakovaný vstup, prístupové práva, aritmetiku, cenové veštce, pôžičky, mosty medzi sieťami a vystavené RPC rozhrania.
Why use it?
Pomáhajú odhaliť chyby, pri ktorých možno obísť oprávnenia, opakovane využiť platbu alebo zmanipulovať cenu či údaje zo siete.

About the project

CyberStrikeAI is a security operations workspace that turns natural-language plans into governed, auditable actions while recording evidence and results for later reuse. Authorized security teams use it to manage agents, tools, vulnerabilities, knowledge, and attack-chain analysis. Catalogue add-ons provide agent and skill workflows for working with the platform.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

blockchain-contract-attack 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 9d 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 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.
