Embodiments of the present invention relate to the instantiation of a coding competition to address problems in program modules. In a typical embodiment, a first annotation will be detected in a program code file having a set of program modules. The first annotation generally indicates a need for a functionality associated with at least one program module of the set of program modules. Responsive to a lack of an existing library comprising the solution, an indication to instantiate a coding competition among a set of developers will be received to provide the solution. In response to the indication, a second annotation will be inserted into the program code file. The coding competition may then be instantiated to identify a set of developer libraries having a potential to provide the solution. Based on the coding competition, the solution may then be identified and implemented.
