TL;DR: AI agents can accelerate analysis and bounded refactoring in a multi-million-line Go monolith, but they fail quickly when sequencing, invariants, or context are incomplete, according to 1Password. The deeper lesson is that production governance depends on explicit constraints, because agentic execution still breaks when intent must be inferred at runtime.
Editorial analysis by NHI Mgmt Group, based on content published by 1Password: “What we learned using AI agents to refactor a monolith”.
Key questions
Q: What breaks when AI agents are allowed to infer change order in production systems?
A: Sequencing errors become correctness failures, especially in schema migrations, dependency rewrites, and service extraction.
Q: Why do deterministic artefacts reduce risk in agentic refactoring?
A: Deterministic artefacts turn an agent from an interpreter into a bounded executor.
Q: What are the signs that an agentic workflow is too underspecified?
A: Common signs include speculation about identifiers, incorrect assumptions about ownership, skipped ordering constraints, and repeated need for rollbacks after apparently reasonable changes.
Practitioner guidance
- Define sequencing constraints before execution Require explicit ordering for schema changes, dependency rewrites, and deployment steps so agents cannot infer safe order from partial context.
- Constrain agents to deterministic artefacts Use agents to build manifests, analyzers, and templates, then execute only against those governed outputs rather than open-ended prompts.
- Treat ambiguity as an escalation condition Stop agent runs when invariants, identifiers, or ownership cannot be verified and route those cases to human review instead of allowing speculation.
Bottom line: AI agents are useful in production change work only when the task sequence, invariants, and rollback conditions are explicit.

Agentic refactoring exposes an assumption collapse in production governance: access and change control were designed for work whose sequence and intent are knowable before execution. That assumption fails when an AI agent fills context gaps at runtime and chooses its own micro-steps inside a broader task. The implication is not simply more automation discipline, but a rethinking of which decisions can remain implicit in production change paths.
A few things that frame the scale:
- Half of companies using generative AI will deploy agentic AI by 2027, according to Deloitte's 2025 Technology Predictions.
A question worth separating out:
Q: How should teams govern parallel AI agent work safely?
A: Parallelism only works when the work is already isolated. Teams should separate tasks into non-overlapping worktrees or equivalent boundaries, define ownership clearly, and ensure that one agent cannot create conflicts that another must repair. Without that structural isolation, concurrency increases inconsistency instead of speed.
