Each hook should be implemented per the `IHook` and `BaseHook` interfaces, interacting with [`v4-core:9293e5a`](https://github.com/Uniswap/v4-core/tree/9293e5ab1deed87e03c176d8af94b1af19eb3900) and [`v4-periphery:1dc3a34`.](https://github.com/Uniswap/v4-periphery/tree/1dc3a344efd901664427d59e41a58364ef0f16ec) ## Detectable Security Threat ### ReInitializable Detects changes in the Hook's storage due to the actions of `beforeInitialize / afterInitialize` if the same Hook can be deployed to the `PoolManager`. Confirms whether the storage accessed by the `beforeInitialize/afterInitialize` functions during Hook initialization is managed by PoolId. ### Time Lock Detects cases where a specific Hook does not operate after a certain period has elapsed. ### External Callable Hook Functions For Hook functions such as `beforeInitialize` / `afterInitialize` / `beforeSwap` / `afterSwap` / `etc.`, detects whether entities other than the PoolManager can execute each function. ### Malicious Hook Detection Can identify risks of gas griefing through gas usage and warns if it can steal user funds or take more tokens than the user intends to pay. ### Price Abnormality Warns when there is a significant difference between the price simulated by Herbicide and the actual price at which the swap occurs. ### Proxy Detection Detects and warns if the Hook Contract is implemented as a proxy. ## Contract Information Analysis ### With PoolKey 1. Hook Delta Simulation: Simulates the amount of funds moved during `Swap/ModifyLiquidity`, allowing users to directly understand the characteristics of the fund flow in the Hook. 2. Static Analysis with Slither: Provides processed information such as security checks and contract information for Hook Contracts verified on BlockScout using Slither, making audits more convenient. ### With Hook Contract 1. Static Analysis with Semgrep: Based on the Herbicide Semgrep Script, it extracts and displays information about the Contract as follows. 1. Library Information 2. Modifier Information 3. Inheritance Information 4. Variable Information --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://gamza-net.gitbook.io/gamza.net/advanced/key-features.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
