# Choose Agents, Workflows, and Skills
> Learn when to use Agents, Workflows, or Skills in Cassidy and how to combine them into reliable solutions for different kinds of work.
Match each business problem with the Cassidy feature best suited to solve it, then combine features when one solution needs both flexibility and consistency.
## What you'll learn
* Use an [Agent](/agents/overview) for flexible conversations, research, and tasks where the path can change
* Use a [Workflow](/workflows/overview) for a predictable process with defined inputs, Actions, and outputs
* Use a [Skill](/skills/overview) to capture a reusable process or standard across people, Agents, and Workflow Actions
* Combine features so an Agent can run a Workflow, a Workflow can use an Agent, or either can follow a shared Skill
## A quick decision guide
Choose an Agent when people need to ask questions, explore information, or adapt the task through conversation.
Choose a Workflow when the same steps should run reliably for every input.
Choose a Skill when the same playbook, tone, approved phrasing, or process should be reused across your organization.
If you are unsure, start with an Agent. Turn repeated requests into a Workflow, and capture company-wide standards in a Skill.
