Trust-Aware Multi-Agent Traceability: Confidence-Calibrated Knowledge Graphs for Consistent Software Artifact Management

2026-06-15 · Source: Artificial Intelligence · Field: Technology & Digital — Software Development & Engineering, Artificial Intelligence & Machine Learning · Depth: Expert, quick

Summary

A novel trust-aware coordination framework is proposed to manage errors and low-confidence decisions in multi-agent AI systems automating software engineering tasks. This framework utilizes a shared knowledge graph as both semantic memory and a coordination surface, allowing agents to assess contributions using calibrated confidence scores. The approach features a two-stage traceability link prediction pipeline, combining embedding-based retrieval with LLM-based multi-criteria analysis. It also includes a traceability seeding mechanism for comparing derivation-time and validation-time confidence, and a consistency protocol for pipeline interactions. This protocol governs through confidence threshold gating, divergence detection, and conflict resolution. Evaluated on an automotive software engineering case study, ablation studies confirmed the essential role of confidence calibration for effective pipeline coordination.

Key takeaway

For AI Engineers designing multi-agent systems for safety-critical software engineering, you should integrate confidence calibration and a shared knowledge graph into your coordination framework. This approach mitigates error propagation and ensures consistent artifact management by enabling agents to assess and build upon contributions reliably. Consider implementing a two-stage link prediction pipeline and a consistency protocol to enhance traceability and reduce compliance risks.
