Callbacks, in words

beforeRemoveLiquidityLiquidityRuns before anyone removes liquidity. Can delay or block LP exits. Read the unlock terms.
beforeSwapSwapRuns before every swap, can override the LP fee. Fees can change per trade. Check the fee range.
afterSwapSwapRuns after every swap with the final amounts. Reacts to trades: burns, pots, reward accounting.
beforeSwapReturnDeltaDeltaLets beforeSwap take or give tokens itself. The hook can change what you pay in. Read every rule that uses it.
afterSwapReturnDeltaDeltaLets afterSwap take a cut of the output. The hook can change what you receive. Taxes and burns live here.

Before you trust it

Quote a small trade first and compare what you receive with a hook-free quote.
If you provide liquidity, find out under which conditions the hook lets you withdraw.

A heuristic read of permissions and settings. It is not an audit and does not check the code itself.

Bits show what a hook may do, not what it does. A Rule Craft pool also publishes its module settings, so its read is exact. See methodology.
