A method may include: retrieving a plurality of configuration files, each configuration file associated with a connected electronic device; parsing each of the plurality of configuration files into a plurality of sections and subsections; storing the parsed configuration files to a database; receiving, from a user interface for the computer program, a configuration-related query; extracting metadata and keywords from the configuration-related query; identifying one of the stored parsed configuration files using the metadata; retrieving the identified stored parsed configuration file; identifying relevant branches in the retrieved configuration file that include the keywords; generating a prompt for a large language model including the configuration-related query and the identified branches as context for the configuration-related query; receiving a response to the prompt from the large language model; and returning the response to the user interface. ## Claims ### Claim 1 A method, comprising: retrieving, by a computer program executed by an electronic device, a plurality of configuration files, each configuration file associated with a connected electronic device in a computer network comprising a plurality of connected electronic devices; parsing, by the computer program, each of the plurality of configuration files into a plurality of sections and subsections; storing, by the computer program, the parsed plurality of configuration files to a database; receiving, from a user interface for the computer program, a configuration-related query; extracting, by the computer program, metadata and keywords from the configuration-related query; identifying, by the computer program, one of the stored parsed configuration files using the metadata; retrieving, by the computer program, the identified one of the stored parsed configuration files; identifying, by the computer program, relevant branches in the retrieved configuration file that include the keywords; generating, by the computer program, a prompt for a large language model including the configuration-related query and the identified relevant branches as context for the configuration-related query;
