Tembo supports agents to solve your software engineering tasks. Each agent has different capabilities, models, and configuration options.

​
Available Agents

​
Claude Code (Default)

Claude Code is Tembo’s default agent, powered by Anthropic’s Claude models. It provides the most reliable and battle-tested experience for solving software engineering tasks. Supported Models:
  • claude-4-5-sonnet (Default)
  • claude-4.1-opus
  • claude-4-sonnet
  • claude-3-7-sonnet

​
Codex

Codex is an agent powered by OpenAI’s latest GPT-5 models with varying reasoning levels. Supported Models:
  • gpt-5-medium (Default)
  • gpt-5-minimal
  • gpt-5-low
  • gpt-5-high

​
Opencode

Opencode is an alternative agent supporting both Anthropic Claude models and OpenAI GPT models. Supported Models:
  • claude-4-5-sonnet (Default)
  • claude-4.1-opus
  • claude-4-sonnet
  • claude-3-7-sonnet

​
Selecting an Agent

Agents are specified using an agent key format: agentType:model Examples:
  • claudeCode:claude-4-5-sonnet
  • codex:gpt-5-medium
  • opencode:claude-4-5-sonnet
If no agent is specified, Tembo defaults to claudeCode:claude-4-5-sonnet.

​
Configuration Files

Each agent can read configuration from rule files in your repository:
  • Claude Code looks for CLAUDE.md or claude.md
  • Codex looks for AGENTS.md or agents.md
  • Opencode looks for AGENTS.md or agents.md
These files allow you to provide agent-specific instructions and coding standards. Learn more about rule files.

​
Switching Between Agents

You can configure which agent to use for your organization or specific tasks through:
  1. Dashboard Settings - Set a default agent for all tasks
  2. API Configuration - Specify an agent key when creating tasks via API
  3. Integration Settings - Configure per-integration agent preferences
Contact your Tembo administrator or check the API documentation for details on agent configuration.
