WordPress actions execute custom logic at specific lifecycle points, while filters modify and return data; in Sage, both are organized within service providers to maintain a scalable boot sequence.

Register WordPress hooks inside the ServiceProvider boot() method by attaching actions or filters, using dependency injection to resolve needed services directly within the callback functions.

Hook timing issues in Sage usually stem from registering outside the correct boot sequence stage or mismatched priorities; mapping registrations to the provider boot order ensures hooks fire correctly.

Yes, Sage's Acorn service providers support dependency injection within hook callbacks, allowing you to resolve services from the container directly when registering actions or filters in the boot method.

Use Sage service providers for hook registration to leverage the structured boot sequence and dependency injection, whereas functions files lack this organized lifecycle management and scalable architecture.

Setting priority and accepted arguments is necessary when adding filters in Sage to control execution order and ensure callbacks receive the correct parameter count during the WordPress boot sequence.
