🌐 Live site: omermaksutii.github.io/RugProof
📦 Latest: v0.2.0 — 44 commands · 23 agents · 42 skills · 11 MCP servers, now with a real test suite and offline-first integrations

A Claude Code plugin that turns your editor into a full-stack smart contract security auditor: vulnerability detection, working exploit PoCs, mainnet-fork simulation, invariant generation, gas profiling, soulbound on-chain audit certificates, and shareable audit cards — Solidity + Vyper across every major EVM chain.

Local dev

git clone https://github.com/omermaksutii/RugProof
cd RugProof
make build       # MCP servers + scripts
make test        # forge tests + NFT tests + MCP smoke test
make audit-demo  # runs the bundled reentrancy exploit (passes)

Quickstart

# In any Solidity project:
/audit                          # full audit on the repo
/audit src/Vault.sol            # audit one file
/quick-scan                     # fast pre-commit-style scan
/audit-live 0xabc... --chain ethereum  # audit a deployed contract by fork
/exploit <finding-id>           # write a working Foundry PoC
/report                         # render Markdown / HTML / PDF / PNG card

23 specialist subagents

Functional: attacker · defender · exploit-poc-writer · invariant-writer · gas-optimizer · remediation-suggester · report-writer · assembly-auditor

Protocol-specific: amm-specialist · lending-specialist · staking-specialist · bridge-specialist · governance-specialist · yield-aggregator-specialist · nft-specialist

Hot-topic specialists (2025): aa-specialist (ERC-4337) · crosschain-messaging-specialist (LayerZero V2 / CCIP / Hyperlane / Wormhole / Axelar) · restaking-specialist (EigenLayer / Symbiotic / Karak) · intents-specialist (ERC-7683 / UniswapX / CoW)

Language / chain / economics: vyper-specialist (Vyper compiler-class bugs) · l2-sequencer-specialist (rollup finality, sequencer uptime, L1↔L2) · economic-rug-specialist (owner powers + 0–100 rugability score) · zk-verifier-specialist (proof-verifier correctness)

42 auto-invoked vulnerability skills

A detection-skill library that auto-activates when Claude sees matching code patterns. Covers the full CWE/SWC catalog plus modern DeFi-specific issues:

Classic (19): reentrancy (incl. read-only and cross-contract) · access control · oracle manipulation · flash-loan attacks · MEV/front-running · signature replay · storage layout · initialization · unchecked calls · DoS vectors · integer issues · delegatecall risks · tx-context misuse · token compatibility · approval issues · EIP-6780 self-destruct · inline assembly · pragma & address hygiene · centralization risk.

Hot-topic 2025 (8): ERC-4337 account abstraction · cross-chain messaging · Permit2 / EIP-2612 · ERC-1271 contract signatures · Diamond / EIP-2535 · restaking & EigenLayer AVS · ERC-7683 intents · ERC-4626 inflation/donation.

v0.2 additions (8): ve-lock governance · fee-on-transfer accounting · signature malleability · MEV / PBS · liquidation cascades · oracle redundancy failure · cross-contract state inconsistency · ZK verifier bugs.

AI-quality meta-skills (4): confidence scoring · multi-pass self-critique (/audit-strict) · known-good reference comparison · false-positive feedback loop (/dismiss + .rugproof.yml ignore: + inline // rugproof-ignore markers).

DX meta-skills (2): caching-and-incremental (skip unchanged files) · progress-and-streaming (live status during long audits).

11 MCP servers

Chain I/O, test runners, history databases, static-analyzer runners — block-explorer (Etherscan v2 multichain) · forge-runner · hardhat-runner · anvil · tenderly · c4-history · sherlock-history · gas-tracker · token-metadata (+ GoPlus safety) · slither-runner · mythril-runner. Every server degrades gracefully to labeled mock data offline, so the plugin works with zero configuration.

4 hooks

Pre-commit quick-scan · pre-push full audit · pre-deploy build-artifact check · post-test coverage analyzer. (Pre-commit and pre-push live as git hook scripts; pre-deploy and post-test wire into Claude Code's Bash hook events via plugin.json.)

5 bundled vulnerable demo contracts

examples/ ships a "wow on first install" set: classic reentrancy vault, spot-oracle lending market, flash-loan governance, ERC-4626 inflation attack, replay-able bridge. Run /demo after install to see Rugproof in action without bringing your own code.

Configuration

Create a .rugproof.yml at the repo root. See .rugproof.yml.example.

severity_threshold: high       # block CI on this severity or worse
chains: [ethereum, berachain, arbitrum, base]
include: ["src/**/*.sol"]
exclude: ["test/**", "script/**"]
ignore:
  - id: REENT-001
    reason: "Single-trusted-caller, reviewed 2025-Q4"

Inline suppression in code:

// rugproof-ignore: REENT-001 — single trusted caller, reviewed 2025-Q4
function trustedOp() external onlyOwner { ... }

Supported

Chains: Ethereum · Berachain · Arbitrum · Base · Optimism · Polygon · BSC · Linea · zkSync · Scroll

Languages: Solidity (full) · Vyper (most patterns) · Stylus / CosmWasm / Solana-Anchor (top vuln classes) · Yul / inline assembly (specialist)

Output formats

/report produces Markdown, HTML, PDF, JSON, and a shareable PNG audit card. /card produces just the PNG — built for social sharing.

Build

One-liner via Makefile:

make build       # builds all 11 MCP servers + scripts
make test        # forge tests + NFT tests + MCP smoke test
make audit-demo  # runs the bundled reentrancy exploit PoC (passes)
make sample-cards   # rerender PNG audit cards from samples/
make sample-html    # rerender HTML pages from samples/

Or manually:

cd mcp && npm install && npm run build
cd ../scripts && npm install && npm run build
forge install                   # if you want to refresh git submodules
forge test -vv                  # exploit PoC against VulnerableVault passes
node scripts/dist/test-mcp.js   # MCP smoke test (11/11 servers should pass)

The plugin.json points to mcp/<name>-mcp/dist/index.js for each server. Most return mock data when API keys / external tools are absent so the plugin works out-of-the-box even without a fully configured environment.

Roadmap

v0.1 shipped the full skeleton; v0.2 hardens it into a tested, real-integration tool.
