# Choose an agent
> Compare the live Agent Console agents and choose the right one for your task
Choose an agent based on the outcome you need. Each agent has its own instructions, skills, resource requirements, and presets.
| Agent | Use it for | Typical output | Important setup |
| ----------------------------------------------------------- | -------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------------- |
| [Builder](/products/agent-console/agents/builder) | Implementing scoped engineering changes | Pull request, branch, or text response | A source-control repository |
| [Reliability](/products/agent-console/agents/reliability) | Investigating failures, tests, freshness issues, and incidents | Diagnosis and, when safe, a draft pull request | Repository and warehouse MCP are optional |
| [Optimization](/products/agent-console/agents/optimization) | Warehouse cost, query performance, and dbt project health | Evidence-based report or draft pull request | Some workflows require a warehouse MCP |
| [Custodian](/products/agent-console/agents/custodian) | Reviewing upstream pull requests for downstream impact | Source-control review and optional downstream remediation | Custodian GitHub access plus an upstream/downstream repository pair |
| Concierge | General request routing and guidance | Coming soon | Not yet available |
If you send a direct message to the Sidecar Slack app, Sidecar chooses among
the available agents. It uses Builder when it cannot classify the request
confidently.
