You could use a separate project, which sounds nightmaroish given the ecosystem evolving so fast and devs that are let the LLM make beheaded chickens seemm orderly and rational.

Or you can use one of the two to create a common source of context that includes code base mapping and depending on your mileage vectorization of the code itself, which I implement as an init command in oopencode as a first step with a project. The skills specs are universal, agents are too, the rest I am not 100% sure but its mostly just markdown descriptions of things until you get into advanced use cases with SDKs so you can set up a skill or agent using a skill+tool to go "file by file, method by method" then write a bash script or find a bloated multimodel harness to have each use it for your purposes.
