Tips

OpenCode is an open-source Claude Code-style TUI; set the backend with `-m provider/model` (Anthropic/OpenAI/local) to avoid vendor lock-in.
For automation use `opencode run "..."` to execute once and exit — lighter than a resident TUI for CI codegen/review.
Encode recurring workflows as subagents (`opencode agent create`) and call them with `--agent` — more stable than repeating instructions in prompts.
Share a session with `/share` for a read-only link to send a colleague the agent's solution without exposing your local environment.
