 * This tool keeps a local cache of certain items, which means that subsequent

 * this when many resources could be shared and need to be queried in a loop.
 *
 * Note that some of these improvements can only be achieved by knowing the
 * logic deeper in other modules. For instance we know that a competency's context
 * is the one of its framework. This tool must be kept in sync with those APIs.
