Abstract: An AI-enabled agent generates computer code based on a natural language description and by injecting predefined code blueprints. The technique includes determining, based on a natural language code description for an unwritten computer program, application parameters. A predefined prompt is identified based on the application parameters and fused with the natural language code description. One or more predefined code portions for the application parameters are identified. A code generation model is invoked using the fused predefined prompt and natural language code description, and the one or more predefined code portions to obtain an initial build of a program. A series of additional coding actions are performed based on a set of coding actions for generating the computer code, during which user feedback is solicited and checkpoints are performed.

Abstract: A system accesses metrics of features of workflows indicating an anomaly, the features represented as nodes in a graph and causal relationships as links, wherein a root node corresponds to the anomaly. The system, for each feature in each subgraph, computes an adjacent contribution score corresponding to each link for which the feature is a causing node, based on the metrics. The system determines a nonadjacent contribution score for each feature of the nodes in the graph to the anomaly by: assigning the adjacent contribution scores of features in a root subgraph of the multiple subgraphs that includes the root node to the corresponding features in the graph, for an adjacent subgraph of the multiple subgraphs that includes a shared feature that is also in the root subgraph, modifying the adjacent contribution scores of unique features of the adjacent subgraph based on the nonadjacent contribution score of the shared feature.
