          When critiquing code style don't be a zealot, we don't like "let" statements but sometimes they are the simpliest option, if someone does a bunch of nesting with let, they should consider using iife (see packages/opencode/src/util.iife.ts)

          Use the gh cli to create comments on the files for the violations. Try to leave the comment on the exact line number. If you have a suggested fix include it in a suggestion code block.
+          If you are writing suggested fixes, BE SURE THAT the change you are recommending is actually valid typescript, often I have seen missing closing "}" or other syntax errors.
+          Generally, write a comment instead of writing suggested change if you can help it.

          Command MUST be like this.

 - `model`: The model to use with OpenCode. Takes the format of `provider/model`. This is **required**.
+- `agent`: The agent to use. Must be a primary agent. Falls back to `default_agent` from config or `"build"` if not found.
 - `share`: Whether to share the OpenCode session. Defaults to **true** for public repositories.
 - `prompt`: Optional custom prompt to override the default behavior. Use this to customize how OpenCode processes requests.
 - `token`: Optional GitHub access token for performing operations such as creating comments, committing changes, and opening pull requests. By default, OpenCode uses the installation access token from the OpenCode GitHub App, so commits, comments, and pull requests appear as coming from the app.
