/v4-hook-reentrancy-via-unlock
Detect reentrancy in Uniswap V4 hooks via the PoolManager unlock/lock callback. V4 uses a singleton PoolManager with transient lock state; all pool mutations happen inside an unlockCallback. A hook that makes external calls during beforeSwap/afterSwap/before*Liquidity (to tokens

Open skill - /solady-erc20-permit2-assumptions
Detect unsafe assumptions about Solady's gas-optimized ERC20/ERC2612 permit and DN404 metadata. Solady's ERC20 uses custom storage slots, returns bools via assembly, exposes a virtual `_constantNameHash`/`_versionHash` for permit domain separation, and its DN404 mirror splits
Open skill - /solady-ownable-init-frontrun
Detect front-runnable ownership initialization in Solady Ownable / OwnableRoles. Solady's `_initializeOwner` is a guarded one-time setter (it reverts with `AlreadyInitialized` on a second call) but it is NOT access-controlled, so in constructor-less deployment paths
Open skill - /solady-safetransferlib-no-contract-check
Detect Solady SafeTransferLib calls that assume the token has code. SafeTransferLib.safeTransfer/safeTransferFrom/safeApprove deliberately skip the EXTCODESIZE check that OpenZeppelin's SafeERC20 performs, so a call to an EOA or a self-destructed/not-yet-deployed token address
Open skill - /v4-hook-delta-accounting
Detect Uniswap V4 hooks that fail to settle currency deltas with the PoolManager. Every credit/debit a hook creates (BeforeSwapDelta, afterSwap hookDelta, take/mint, donate, settle/sync) is tracked in the manager's transient nonzeroDeltaCount; if the books aren't flat when
Open skill - /v4-hook-permission-flags-mismatch
Detect Uniswap V4 hooks whose address-encoded permission flags don't match the callbacks the hook actually implements. In V4 the hook's permissions live in the low bits of its deployed address (mined via CREATE2 salt) and must agree with getHookPermissions(); a callback the hook
