 ### Agent pool jobs
 
-Agent pool obs are the most common jobs. These jobs run on an agent in an agent pool. You can specify the pool to run the job on, and you can also specify demands to specify what capabilities an agent must have to run your job. Agents can be Microsoft-hosted or self-hosted. For more information, see [Azure Pipelines agents](../agents/agents.md).

 * When you're using Microsoft-hosted agents, each job in a pipeline gets a fresh agent.
 * When you're using self-hosted agents, you can use [demands](/azure/devops/pipelines/yaml-schema/pool-demands) to specify what capabilities an agent must have to run your job. You can get the same agent for consecutive jobs, depending on whether there's more than one agent in your agent pool that matches your pipeline's demands. If there's only one agent in your pool that matches the pipeline's demands, the pipeline waits until this agent is available.
