OpenCode includes two built-in agents you can switch between with the Tab key.

• build - Default, full-access agent for development work
• plan - Read-only agent for analysis and code exploration
  • Denies file edits by default
  • Asks permission before running bash commands
  • Ideal for exploring unfamiliar codebases or planning changes

Also included is a general subagent for complex searches and multistep tasks. This is used internally and can be invoked using @general in messages.
