HELIOS

HELIOS— Heuristic Evaluation & Launch Intelligence for Operational Safety Every year, configuration changes cause billions of dollars in outages. Traditional CI/CD tools validate syntax, schemas, and tests, but they cannot reason about organizational consequences. HELIOS-V2 fills this gap. HELIOS-V2 is a decentralized multi-agent reasoning system built on the Band SDK. Instead of relying on a rigid pipeline, six specialized agents collaborate inside a shared Band Room to evaluate configuration changes before deployment. Each agent has a dedicated responsibility: * SENTINEL - performs semantic analysis of configuration changes. * CHRONICLE - searches historical incidents and organizational knowledge. * MERIDIAN - evaluates dependencies and blast radius. * CONTEXT - analyzes organizational readiness and operational signals. * ORACLE - predicts technical, financial, and operational consequences. * ARBITER - aggregates all evidence and issues the final verdict. The agents communicate through an event-driven Band orchestration layer using structured context and agent handoffs. The system produces one of four explainable decisions: SHIP, WARN, STAGE, BLOCK. HELIOS integrates with GitHub Actions, APIs, and local workflows to automatically prevent dangerous deployments. Rather than asking, "Is this configuration valid?", HELIOS asks, "Can your business survive this configuration?" The system was evaluated on a 73-case synthetic benchmark and achieved 94.5% overall accuracy. It was also backtested against five major real-world incidents, including CrowdStrike, Facebook, GitLab, Knight Capital, and AWS S3. HELIOS correctly blocked all five catastrophic failures. By combining historical evidence, dependency graphs, organizational signals, and explainable multi-agent collaboration, HELIOS-V2 provides an enterprise-grade safety layer between "CI passed" and "Production is on fire."
