What it does
Assess Smart Contract Security is an agent skill from cyberful/cyberful. Assess the security of a smart-contract system across protocol economics, trust roles, upgrade and governance paths, oracle and bridge dependencies, deployment state, and off-chain operators. Use for broad EVM or cross-chain risk reviews before routing code, invariant, or toolchain work.
Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `agents/openai.yaml`, `assets/protocol-risk-ledger.template.json` and `references/protocol-risk-method.md`).
It sits in Backend & APIs, covering Smart contracts and Smart contract auditing. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.
When your agent uses it
- Cross-chain risk reviews before routing code
- Tasks that involve Smart contracts

Example prompts
- “/assess-smart-contract-security”
What it can do on your machine
Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Assess Smart Contract Security loads about 651 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 80 tokens; SKILL.md has 194 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Assess Smart Contract Security
Assess the implemented protocol as a socio-technical system. Contract source alone cannot establish the deployed bytecode, active configuration, privileged operators, economic dependencies, or cross-chain state that determine real exposure.
Establish the system and unacceptable outcomes
Inventory contracts, proxies, factories, libraries, tokens, roles, multisigs, timelocks, keepers, relayers, oracles, bridges, frontends, indexers, deployment networks, and upgrade history. Define unacceptable outcomes in asset and state terms: unauthorized value transfer, insolvency, frozen funds, unbacked issuance, governance capture, replay, censorship, or unrecoverable liveness loss.
Copy assets/protocol-risk-ledger.template.json into the workarea. Read references/protocol-risk-method.md before rating economic or cross-system risk.
Reconcile claims with deployed evidence
Trace each critical outcome to authority, callable transitions, external state, timing, pricing, liquidity, and failure assumptions. Compare documentation, source, build artifacts, deployment bytecode, initialization, live roles, and operational procedures without treating any one source as canonical.
Route source-level review to audit-smart-contract-security, executable properties to test-smart-contract-invariants, and Foundry or Anvil operation to operate-evm-security-toolchain. Do not duplicate those procedures here.
Deliver
Produce a bounded risk ledger with evidence, affected assets, prerequisites, exploitability conditions, blast radius, existing controls, uncertainty, owner, treatment, and validation route. Separate a plausible mechanism from a deployable attack and from demonstrated impact.
