 #### Development Notes
 
-**API Client Generation**: After making changes to the TypeScript API endpoints in `packages/opencode/src/server/server.ts`, you need to regenerate the Go client and OpenAPI specification:
-
-```bash
-$ cd packages/tui
-$ go generate ./pkg/client/
-```
-
-This updates the generated Go client code that the TUI uses to communicate with the backend server.
+**API Client**: After making changes to the TypeScript API endpoints in `packages/opencode/src/server/server.ts`, you will need the opencode team to generate a new stainless sdk for the clients.

+title: Rules
+---
+
+You can provide custom instructions to opencode by creating an `AGENTS.md` file. This is similar to `CLAUDE.md` or Cursor's rules. It contains instructions that will be included in the LLM's context to customize its behavior for your specific project.
+
+---
+
+## Initialize
+
+To create a new `AGENTS.md` file, you can run the `/init` command in opencode.
+
+:::tip
+You should commit your project's `AGENTS.md` file to Git.
+:::
+
+This will scan your project and all its contents to understand what the project is about and generate an `AGENTS.md` file with it. This helps opencode to navigate the project better.
+
+If you have an existing `AGENTS.md` file, this will try to add to it.
+
+---
+
+## Example
+
+You can also just create this file manually. Here's an example of some things you can put into an `AGENTS.md` file.
+
+```markdown title="AGENTS.md"
+# SST v3 Monorepo Project
+
+This is an SST v3 monorepo with TypeScript. The project uses bun workspaces for package management.
+
+## Project Structure
+- `packages/` - Contains all workspace packages (functions, core, web, etc.)
+- `infra/` - Infrastructure definitions split by service (storage.ts, api.ts, web.ts)
+- `sst.config.ts` - Main SST configuration with dynamic imports
+
+## Code Standards
+- Use TypeScript with strict mode enabled
+- Shared code goes in `packages/core/` with proper exports configuration
+- Functions go in `packages/functions/`
+- Infrastructure should be split into logical files in `infra/`
+
+## Monorepo Conventions
+- Import shared modules using workspace names: `@my-app/core/example`
+```
+
+We are adding project-specific instructions here and this will be shared across your team.
+
+---
+
+## Types
+
+opencode also supports reading the `AGENTS.md` file from multiple locations. And this serves different purposes.
+
+### Project
+
+The ones we have seen above, where the `AGENTS.md` is placed in the project root, are project-specific rules. These only apply when you are working in this directory or its sub-directories.
+
+### Global
+
+You can also have global rules in a `~/.config/opencode/AGENTS.md` file. This gets applied across all opencode sessions.
+
+Since this isn't committed to Git or shared with your team, we recommend using this to specify any personal rules that the LLM should follow.
+
+---
+
+## Precedence
+
+So when opencode starts, it looks for:
+
+1. **Local files** by traversing up from the current directory
+2. **Global file** by checking `~/.config/opencode/AGENTS.md`
+
+If you have both global and project-specific rules, opencode will combine them together.

+
+By default, opencode uses our own `opencode` theme.
+
+---
+
+## Built-in themes
+
+opencode comes with several built-in themes.
+
+| Name | Description |
+| --- | --- |
+| `system` | Adapts to your terminal's background color |
+| `tokyonight` | Based on the Tokyonight theme |
+| `everforest` | Based on the Everforest theme |
+| `ayu` | Based on the Ayu dark theme |
+| `catppuccin` | Based on the Catppuccin theme |
+| `gruvbox` | Based on the Gruvbox theme |
+| `kanagawa` | Based on the Kanagawa theme |
+| `nord` | Based on the Nord theme |
+| `matrix` | Hacker-style green on black theme |
+| `one-dark` | Based on the Atom One Dark theme |
+
+And more, we are constantly adding new themes.
+
+---
+
+## System theme
+
+The `system` theme is designed to automatically adapt to your terminal's color scheme. Unlike traditional themes that use fixed colors, the _system_ theme:
+
+- **Generates gray scale**: Creates a custom gray scale based on your terminal's background color, ensuring optimal contrast.
+- **Uses ANSI colors**: Leverages standard ANSI colors (0-15) for syntax highlighting and UI elements, which respect your terminal's color palette.
+- **Preserves terminal defaults**: Uses `none` for text and background colors to maintain your terminal's native appearance.
+
+The system theme is for users who:
+
+- Want opencode to match their terminal's appearance
+- Use custom terminal color schemes
+- Prefer a consistent look across all terminal applications
+
+---
+
+## Using a theme
+
+You can select a theme by bringing up the theme select with the `/theme` command. Or you can specify it in your [config](/docs/config).
