Callbacks, in words

beforeInitializeInitRuns before the pool's starting price is set. Can refuse to open the pool or check who opens it.
afterAddLiquidityLiquidityRuns after liquidity is added. Often used to track LP positions for rewards.
afterRemoveLiquidityLiquidityRuns after liquidity is removed. Settles rewards or exit fees for the leaving LP.
afterSwapSwapRuns after every swap with the final amounts. Reacts to trades: burns, pots, reward accounting.
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.
The fee is set per swap. Ask for the fee bounds, or check them in verified source.

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.
