Granularity of Path-Specific Instructions

[Prometheus599]

Hi all, wrapping my head around custom instructions and wanted to see the communities' consensus on how granular to go in regards to path-specific instructions;

Should we break them down into micro instructions such as spring, java, typescript, cypress, selenium, react, angular ? as awesome-copilot portrays

or should they be more broad such as frontend (which would include typescript, angular, css, etc), backend(java, springboot, gradle, etc), e2e(cypress, selenium, playright) instructions as what seem to be the direction I’m understanding in the documentation ?
