A stripped-down version of a library is generated from server source code extracted from a server project. The transitive closure of program entities extracted from the server source code and referenced by the extracted program entities can be computed. A placeholder entity can be inferred for an entity defined by the transitive closure computation if a definition of the entity cannot be found in the server source code. The stripped-down library generated from the extracted server source code is received by a reflection-based component that uses reflection to generate documentation and disclosure information helpful in the development of the client source code. A placeholder entity can be marked or decorated to signal to the reflection-based component that client source code is not to be generated for the decorated entities.
