coordinating a plurality of specialized agents within a multi-agent orchestra operating concurrently with asynchronous communication, the plurality of specialized agents including:
a context analysis agent that processes a temporal knowledge graph and extracts technical concepts with associated skill level indicators;
a question generation agent that generates candidate assessment questions targeted to detected skill levels based on the extracted technical concepts;
a quality assurance agent that evaluates the candidate assessment questions against the temporal knowledge graph and assigns quality scores based on alignment between question difficulty and demonstrated skill progression;
a validation agent that verifies schema compliance of the candidate assessment questions; and
a refinement agent that iteratively improves the candidate assessment questions based on feedback messages from other agents;
wherein the context analysis agent, the question generation agent, quality assurance agent, the validation agent, and the refinement agent are computerized machine learning agents;
managing coordination of the plurality of specialized agents through a message passing protocol wherein agents exchange structured messages including:
dependency declarations that specify prerequisite processing requirements;
blocking conditions that pause agent processing pending other agent outputs; and
partial results that enable downstream agents to begin processing before upstream agents complete;
enabling, through the message passing protocol, bidirectional communication between the agents, wherein the bidirectional communication enables agents to request additional processing from other agents and to provide intermediate results that dynamically adjust other agents' processing strategies;
implementing an adaptive task allocation mechanism wherein agents signal their processing capacity and confidence levels, enabling dynamic routing of subtasks to agents based on current load and specialization;
performing dual-layer validation on the candidate assessment questions, wherein the dual-layer validation comprises:
performing structural validation using defined schema checking to verify field presence, data type consistency, and format compliance; and
performing semantic validation using a fine-tuned language model, wherein the semantic validation includes:
duplicate detection through semantic similarity analysis of question embeddings;
relevance scoring by comparing question content to source concepts in the temporal knowledge graph; and
skill-level alignment verification to ensure question difficulty matches demonstrated skill levels;
implementing a feedback loop where:
semantic validation results indicating systematic failure patterns are provided to inform dynamic schema refinement in the structural validation; and
structural validation failures provide contextual information to enable root cause analysis of generation errors in the semantic validation; and
requiring both validation layers to pass for acceptance of the candidate assessment questions; and
generating formatted assessment outputs based on validated assessment questions, wherein the formatted assessment outputs include metadata linking each question to specific commits and skill progression stages in the temporal knowledge graph.
