WorkflowPerturb: Calibrated Stress Tests for Evaluating Multi-Agent Workflow Metrics

arXiv:2602.17990v2 Announce Type: replace Abstract: Multi-agent LLM systems that generate structured workflows from natural-language requests are now deployed in production across cloud automation, DevOps, and enterprise process orchestration. Operating such systems exposes a recurring change-management problem. Routine updates, such as re-running the same input, swapping the underlying LLM, or refactoring an agent's prompt or orchestration code, frequently produce workflows that differ substantially from previously validated references. Engineers are then left without a principled way to deci

Why this matters
Why now

The proliferation of multi-agent LLM systems in production, coupled with the inherent instability of current development practices, necessitates robust evaluation frameworks.

Why it’s important

This development addresses a critical vulnerability in the deployment of AI agents, ensuring their reliability and trustworthiness as they assume more complex and critical functions within enterprise operations.

What changes

The introduction of calibrated stress tests provides a principled method for evaluating multi-agent workflow metrics, moving beyond ad-hoc validation to systemic robustness checks.

Winners
  • · Enterprises deploying AI agents
  • · AI agent developers
  • · Cloud automation platforms
  • · DevOps teams
Losers
  • · Organizations relying on ad-hoc validation
  • · Legacy process orchestration providers
Second-order effects
Direct
