 ### Contributing
 
+For any new features we'd appreciate it if you could open an issue first to discuss what you'd like to implement. We're pretty responsive there and it'll save you from working on something that we don't end up using. No need to do this for simpler fixes.

+#### 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:

+$ cd packages/tui
+$ go generate ./pkg/client/
+```
+
+This updates the generated Go client code that the TUI uses to communicate with the backend server.

-- the title should be a summary of the user's message
-- it should be one line long
-- do not use quotes or colons
-- the entire text you return will be used as the title
-- never return anything that is more than one sentence (one line) long
+Generate a short title based on the first message a user begins a conversation with. CRITICAL: Your response must be EXACTLY one line with NO line breaks, newlines, or multiple sentences.
+
+Requirements:
+- Maximum 50 characters
+- Single line only - NO newlines or line breaks
+- Summary of the user's message
+- No quotes, colons, or special formatting
+- Do not include explanatory text like "summary:" or similar
+- Your entire response becomes the title

+IMPORTANT: Return only the title text on a single line. Do not add any explanations, formatting, or additional text.

+# TUI Agent Guidelines
+
+## Build/Test Commands
+
+- **Build**: `go build ./cmd/opencode` (builds main binary)
+- **Test**: `go test ./...` (runs all tests)
+- **Single test**: `go test ./internal/theme -run TestLoadThemesFromJSON` (specific test)
+- **Generate client**: `go generate ./pkg/client/` (after server endpoint changes)
+- **Release build**: Uses `.goreleaser.yml` configuration
+
+## Code Style
+
+- **Language**: Go 1.24+ with standard formatting (`gofmt`)
+- **Imports**: Group standard, third-party, local packages with blank lines
+- **Naming**: Go conventions - PascalCase exports, camelCase private, ALL_CAPS constants
+- **Error handling**: Return errors explicitly, use `fmt.Errorf` for wrapping
+- **Structs**: Define clear interfaces, embed when appropriate
+- **Testing**: Use table-driven tests, `t.TempDir()` for file operations
+
+## Architecture
+
+- **TUI Framework**: Bubble Tea v2 with Lipgloss v2 for styling
+- **Client**: Generated OpenAPI client communicates with TypeScript server
+- **Components**: Reusable UI components in `internal/components/`
+- **Themes**: JSON-based theming system with override hierarchy
+- **State**: Centralized app state with message passing
