- Example Fork DetectionTEMPLATE — replace with the description of your rule. Should activate on the specific code patterns your fork has. Activate on `<your trigger keywords or function names>`.Votes: 0GitHub stars: 36
- Solady Erc20 Permit2 AssumptionsDetect 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 ERC20/ERC721 logic — integrators that assume OZ-style behavior, revert strings, or that `name()`/`decimals()` are always present can misbehave. Activate on solady/tokens imports, ERC2612 permit flows, DN404, or off-chain...Votes: 0GitHub stars: 36
- Solady Ownable Init FrontrunDetect 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 (minimal-proxy clones, EIP-1167, factory `create`/`create2` without atomic init) an attacker can call the public initializer first and seize ownership. Activate on solady Ownable/OwnableRoles in clones, factories, or any non-atomi...Votes: 0GitHub stars: 36
- Solady Safetransferlib No Contract CheckDetect 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 returns success with no transfer. Activate whenever code imports solady SafeTransferLib, calls safeTransfer/safeTransferFrom on a user-supplied or upgradeable token address, or routes arbitrary tokens.Votes: 0GitHub stars: 36
- V4 Hook Delta AccountingDetect 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 unlock returns, the whole transaction reverts (CurrencyNotSettled), and mismatched take/settle/donate either strands hook funds in the manager or lets a swap leave with unpaid debt. Activate on hooks returning deltas, calli...Votes: 0GitHub stars: 36
- V4 Hook Permission Flags MismatchDetect 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 implements but whose flag bit is unset is never invoked, and a flag set without a real implementation makes pool initialization revert in Hooks.validateHookPermissions. Activate on any BaseHook/IHooks contract, getHoo...Votes: 0GitHub stars: 36
- V4 Hook Reentrancy Via UnlockDetect 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 with hooks, arbitrary routers, or user-controlled contracts) can be re-entered, and because the manager is already unlocked the attacker can recursively swap/modify liquidity against stale hook state. Activate on any ...Votes: 0GitHub stars: 36
- Access ControlDetect missing or incorrect access control — missing modifiers, wrong role checks, privileged function exposure, public initializers, and role-escalation paths. Activate on any function that mutates state, transfers funds, mints tokens, sets admin parameters, upgrades implementations, or pauses/unpauses.Votes: 0GitHub stars: 36
- Approval IssuesDetect ERC-20 approval pitfalls — approve race (front-run), missing safeApprove, infinite approvals, approval-without-revoke, Permit2 misuse, max-approval to untrusted contracts. Activate on `approve`, `safeApprove`, `permit`, `forceApprove`, `Permit2`, `IERC20.allowance`.Votes: 0GitHub stars: 36
- Caching And IncrementalAlways-on meta-skill — cache audit results per file by content hash so unchanged files aren't re-analyzed on subsequent runs. Activate on every /audit, /quick-scan, /audit-changes invocation.Votes: 0GitHub stars: 36
- Centralization RiskDetect centralization and trust-assumption risks — admin powers, single-key risk, missing timelocks, upgrade authority, treasury keys, pause permanence, blacklisting authority, oracle authority. Activate on `onlyOwner`, `onlyRole`, `AccessControl`, upgrade authorizations, pause/unpause functions, mint/burn caps, treasury/fee setters.Votes: 0GitHub stars: 36
- Confidence ScoringAlways-on meta-skill — for every finding produced, attach a confidence level (HIGH/MEDIUM/LOW) and a reasoning trace. Activate on every /audit, /audit-deep, /audit-changes, /audit-live, /quick-scan invocation.Votes: 0GitHub stars: 36

- Cross Contract StateDetect cross-contract state inconsistency — two or more contracts sharing a token, oracle, or price feed where one mutates and another reads stale, cached state that drifts from source of truth, non-atomic multi-contract updates, accounting that assumes synchronized state, and reads during callbacks. Activate whenever a system spans multiple contracts that must agree on a value but update at different times.Votes: 0GitHub stars: 36

- Fee On TransferDetect fee-on-transfer / deflationary / rebasing token accounting bugs — crediting the *passed amount* instead of the measured balance delta.
