Background & analysis
On November 1, 2026, a developer published an article in the AI section of DEV Community titled 'Workflow vs Agent: A Scenario-Based Selection Cheat Sheet.' The piece targets developers trying to decide between two orchestration styles, and it frames the decision around one question: is the execution path predictable in advance?
According to the article, when every step is known ahead of time — for example, a pipeline that fetches data, sends it through a prompt, parses the output, and stores the result — the recommended approach is a Workflow. The reasoning is that workflows offer immutable execution, are easy to test, and keep token usage predictable. When the path instead depends on content or user intent, such as having to answer any compliance question that comes up, the article recommends an Agent, which chooses tools at runtime and handles unknown sub-tasks on the fly.
The author adds a third case: regulatory settings that require auditable logs and version-controlled prompts are better served by Workflow, since its deterministic orchestration makes it easier to produce the immutable records those settings demand.
As of now, no follow-up reports indicate that the article has been revised or that the community has debated its criteria, so the selection guide stands as the author originally presented it.

A DEV Community post offers a quick diagnosis table for choosing between workflows and agents: use a workflow when every step is known in advance and you need immutable execution, easy testing and predictable token usage; use an agent when the path depends on content or user intent and tools must be chosen at runtime. It also notes that regulated settings needing immutable logs and version-controlled prompts favor workflows.
