OpenCode

Open-source, model-agnostic terminal coding agent

OpenCode is an open-source terminal-based coding agent that connects to multiple language models and performs autonomous software engineering tasks from the command line. It edits files, runs tests, manages git workflows, and iterates on code with minimal human intervention. The v1.17.8 release from June 2026 improves tool calling reliability, multi-file refactoring, and support for local and remote model backends.

1 Start with small, well-defined tasks to learn how the agent plans changes
2 Use a local model for sensitive codebases and remote models for heavier reasoning
3 Commit or stash work before starting a session so you can roll back easily
4 Configure custom test commands so OpenCode validates every change
5 Review the generated diff carefully before accepting multi-file edits

Refactoring a Legacy Module

Use OpenCode to safely refactor an old codebase with tests and git checkpoints.

STEPS:
  1. Open the repository in your terminal and run `opencode`
  2. Ask the agent to refactor a specific module and preserve existing behavior
  3. Review the proposed plan and approve the file changes
  4. Run the configured test suite to catch regressions
  5. Commit the changes with a descriptive message
  6. Iterate on edge cases the tests reveal

Adding a Feature from a Ticket

Turn a GitHub issue or ticket into working code using the terminal agent.

STEPS:
  1. Paste the ticket description into OpenCode as the task
  2. Let the agent explore the codebase and identify relevant files
  3. Approve the implementation plan
  4. Run tests and fix failures together with the agent
  5. Review the final diff and open a pull request
