GREP ARSENAL — MASTER REFERENCE

All grep commands in one place. Run in the first 30 minutes of any new target. Replaces: 03-grep-surface-map, 14-grep-master-patterns + grep sections from 04-13

HOW TO USE THE SURFACE MAP

Process:

  1. Run ALL 10 blocks below (takes ~5 min)
  2. Collect all results in a notes file
  3. Tier-rank the hits (see Tier System below)
  4. In pass 1: READ everything, DON'T investigate yet
  5. In pass 2: Deep-dive on Tier 1 + 2 items

Tier System:

  • Tier 1 — Near privileged code, external calls, or state changes with no guards → Investigate first
  • Tier 2 — Interesting patterns that need context before judging → Investigate after Tier 1
  • Tier 3 — Informational only (documentation, test files, comments) → Skip unless Tier 1+2 exhausted

THE 10 GREP BLOCKS (Copy-Paste Each)

Block 1 — Access Control
echo "=== ACCESS CONTROL ===" && \
grep -rn "tx\.origin" src/ --include="*.sol" && \
grep -rn "msg\.sender == owner\b" src/ --include="*.sol" && \
grep -rn "modifier only" src/ --include="*.sol" -A5 && \
grep -rn "onlyOwner\|onlyAdmin\|onlyRole" src/ --include="*.sol" | wc -l && \
grep -rn "def admin_\|router\..*admin\|function.*[Aa]dmin" src/ --include="*.sol"

Red flags:

  • tx.origin used for auth → Tier 1 (phishing vector)
  • Modifier uses if (condition) { _; } without else → Tier 1 (silent bypass — function still executes for unauthorized callers)
  • onlyOwner count << total external function count → likely missing guards on siblings
Block 2 — Reentrancy
echo "=== REENTRANCY ===" && \
grep -rn "\.call{value\|\.call(" src/ --include="*.sol" && \
grep -rn "\.transfer(\|\.send(" src/ --include="*.sol" && \
grep -rn "safeTransfer\|safeTransferFrom" src/ --include="*.sol" && \
grep -rn "onERC721Received\|onERC1155Received\|tokensReceived" src/ --include="*.sol" && \
grep -rn "nonReentrant\|ReentrancyGuard" src/ --include="*.sol"

Red flags:

  • .call{value:} or safeTransfer BEFORE state updates in same function → Tier 1 (CEI violation)
  • onERC721Received/onERC1155Received hooks present → check for reentrancy path
  • External calls present but nonReentrant missing → verify CEI is followed
Block 3 — Oracle / Price
echo "=== ORACLE / PRICE ===" && \
grep -rn "slot0\b" src/ --include="*.sol" && \
grep -rn "getReserves()" src/ --include="*.sol" && \
grep -rn "latestRoundData\|latestAnswer" src/ --include="*.sol" && \
grep -rn "updatedAt" src/ --include="*.sol" && \
grep -rn "block\.timestamp" src/ --include="*.sol" | grep -v "//\|test\|Test" | head -20

Red flags:

  • slot0() used for price → Tier 1 (Uniswap V3 spot, flash-loan manipulable)
  • getReserves() used for price → Tier 1 (Uniswap V2 spot, flash-loan manipulable)
  • latestRoundData without updatedAt check → Tier 1 (stale Chainlink price)
  • latestAnswer → Tier 1 (deprecated, no round validation)
Block 4 — Arithmetic / Math
echo "=== ARITHMETIC ===" && \
grep -rn "unchecked {" src/ --include="*.sol" && \
grep -rn "/ \|/=" src/ --include="*.sol" | grep -v "//\|test\|Test" | head -30 && \
grep -rn "mulDiv\|FullMath\|PRBMath" src/ --include="*.sol" && \
grep -rn "\* 10\*\*\|* 1e18\|* WAD\|* RAY" src/ --include="*.sol"

Red flags:

  • unchecked {} blocks → manually verify each (Solidity 0.8+ unwraps here)
  • Division before multiplication (a / b * c) → precision loss
  • / 1e18 in contract that handles 6-decimal tokens → decimal mismatch
Block 5 — Input Validation
echo "=== INPUT VALIDATION ===" && \
grep -rn "address(0)\b" src/ --include="*.sol" && \
grep -rn "require.*length\|\.length ==" src/ --include="*.sol" && \
grep -rn "delegatecall" src/ --include="*.sol" && \
grep -rn "abi\.decode\|abi\.encodePacked" src/ --include="*.sol" | head -20

Red flags:

  • delegatecall with user-controlled target → Tier 1 (arbitrary code execution)
  • abi.decode on user-supplied calldata without length validation → Tier 1
  • Array params in batch functions without dedup check → Tier 1 (double-count attack)
Block 6 — Token Handling
echo "=== TOKEN HANDLING ===" && \
grep -rn "IERC20\.\|ERC20\." src/ --include="*.sol" | grep "transfer\b\|transferFrom\b" && \
grep -rn "SafeERC20\|safeTransfer\b" src/ --include="*.sol" | head -10 && \
grep -rn "balanceOf(address(this))" src/ --include="*.sol" && \
grep -rn "permit(" src/ --include="*.sol" | grep -v "//\|IERC20Permit" && \
grep -rn "try.*permit\|catch.*permit" src/ --include="*.sol"

Red flags:

  • token.transfer() without SafeERC20.safeTransfer() → Tier 1 (return value unchecked, fails silently on old USDT)
  • balanceOf(address(this)) for pricing/shares → Tier 1 (donation attack vector)
  • permit() without try/catch wrapper → Tier 2 (frontrun DoS possible)
Block 7 — ERC4626 / Vault
echo "=== ERC4626 / VAULT ===" && \
grep -rn "totalAssets\|convertToShares\|previewDeposit\|previewMint" src/ --include="*.sol" && \
grep -rn "_decimalsOffset\|decimalsOffset\|virtual_shares\|dead.*shares" src/ --include="*.sol" && \
grep -rn "shares.*supply\|totalSupply\|mint.*shares" src/ --include="*.sol" | head -20

Red flags:

  • ERC4626 present but _decimalsOffset() NOT present → Tier 1 (first depositor inflation)
  • totalAssets() uses balanceOf(address(this)) → Tier 1 (donation attack)
  • mint() or deposit() called without same validation path → Tier 1 (MetaPool bug: mint skipped receipt check)
Block 8 — Proxy / Upgradeable
echo "=== PROXY / UPGRADE ===" && \
grep -rn "_authorizeUpgrade\|upgradeTo\|upgradeToAndCall" src/ --include="*.sol" && \
grep -rn "initialize(" src/ --include="*.sol" | grep -v "//\|test\|Test" && \
grep -rn "_disableInitializers\|initializer\b\|Initializable" src/ --include="*.sol" && \
grep -rn "StorageSlot\|ERC1967\|TransparentProxy\|UUPSUpgradeable" src/ --include="*.sol"

Red flags:

  • _authorizeUpgrade() without onlyOwner or role check → Tier 1 (anyone can upgrade)
  • initialize() without initializer modifier → Tier 1 (re-initialization possible)
  • Proxy present but _disableInitializers() NOT in impl constructor → Tier 1 (impl attackable)
Block 9 — Signature / Replay
echo "=== SIGNATURES ===" && \
grep -rn "ecrecover\|ECDSA\.recover" src/ --include="*.sol" && \
grep -rn "chainId\|block\.chainid\|DOMAIN_SEPARATOR" src/ --include="*.sol" && \
grep -rn "nonces\[" src/ --include="*.sol" && \
grep -rn "keccak256.*abi\.encode" src/ --include="*.sol" | head -20

Red flags:

  • ecrecover present but chainId/DOMAIN_SEPARATOR NOT present → Tier 1 (cross-chain replay)
  • ecrecover without nonce → Tier 1 (same-chain replay)
  • ecrecover return not checked against address(0) → Tier 1 (invalid sigs succeed)
Block 10 — State Completeness / Access
echo "=== STATE COMPLETENESS ===" && \
grep -rn "grantRole\|revokeRole\|hasRole" src/ --include="*.sol" && \
grep -rn "bytes32.*ROLE\s*=" src/ --include="*.sol" && \
grep -rn "function.*migrate\|function.*batch.*stake\|function.*multiStake" src/ --include="*.sol" -A10 && \
grep -rn "} catch" src/ --include="*.sol" -A5 | grep -A5 "revert\|Error" && \
grep -rn "cached\|_cache\|lastKnown\|storedBalance" src/ --include="*.sol"

Red flags:

  • Role defined but grantRole() call for that role NOT found anywhere → Tier 1 (role permanently empty)
  • Array-based function: flag = true OUTSIDE/AFTER loop → Tier 1 (empty array bypass)
  • } catch { revert } on critical path → Tier 2 (liveness DoS if external changes)
  • Cache variable initialized to 0 with no first-access guard → Tier 1 (uninitialized cache)

PROTOCOL-SPECIFIC PATTERNS

grep -rn "/ 1e18\|/ WAD" src/ --include="*.sol"

grep -rn "rewardPerSecond\|ratePerSecond\|flowRate\|perSecond" src/ --include="*.sol"
grep -rn "uint128.*reward\|uint96.*rate" src/ --include="*.sol"
# uint128 accumulator × per-second rate = overflow risk on long time periods

# claimed <= claimable <= queued must hold — check all update paths

# Cross-chain signature reuse
grep -rn "keccak256.*abi\.encodePacked\|ECDSA\.recover" src/ --include="*.sol"
grep -rn "chainId\|block\.chainid" src/ --include="*.sol"
# ecrecover WITHOUT chainId = same sig valid on all chains

ツール一覧はメタデータであり、互換性のテスト結果ではありません。プロンプトは提案です。

小さなタスクから始める

  1. 1ソースを読み、入力、出力、依存関係、権限を確認します。
  2. 2Agent に計画を求め、設定と費用を承認してから隔離環境でテストします。
  3. 3出力と変更ファイルを確認し、実行した結果だけを報告します。再現用にソースの版を保存します。

依存関係、API キー、外部サービスの料金をソースで確認してください。公開リポジトリでも全サービスが無料とは限りません。

  • Dependency or permission surface needs review
  • Permission surface may require sandboxing
  • Potential broker, wallet, exchange, or real-money execution surface; sandbox and explicit approval are required
  • The SKILL.md excerpt is truncated, but the visible content is well-structured and complete for the described purpose.
  • The grep commands assume a `src/` directory and Solidity files; projects with different layouts may require adjustments.
  • This skill may touch real-money trading, broker, wallet, or exchange operations; use only in a sandbox with explicit approval.
