The Core UI Components of OpenWork form a sophisticated interface layer designed to facilitate human-AI collaboration through the OpenCode engine. These components are built using SolidJS and Tailwind CSS, focusing on premium UX, high-performance interactivity, and clear transparency of agentic workflows. The system is architected to handle complex data streams, including real-time execution plans, tool calls, and structured artifacts.
The component library serves as the primary bridge between the user and the OpenCode Integration, exposing product primitives such as Tasks, Steps, and Audit Logs. It follows a "mobile-first" philosophy with adaptive layouts, bottom navigation for handheld devices, and springy transitions to ensure a calm, high-contrast user experience.

Interactive Input: The Composer
The Composer is a high-level input component that manages rich text prompts, file attachments, and agent selection. It uses a content-editable div to support "mentions" (agents or files) and handles complex keyboard interactions for history navigation and command menus.
Key Logic and Features
- Rich Mentions: Supports
@mentions for both agents and workspace files, dynamically rendering them as non-editable spans within the text stream. - History Navigation: Implements a history buffer for prompts and shell commands, allowing users to cycle through previous inputs using Arrow keys.
- Attachment Management: Handles local file uploads and clipboard paste events, enforcing MIME type restrictions and size limits (e.g., 8MB).
- Model Variants: Integrated picker for "Thinking Effort" variants (Low, Medium, High, X-High).
The diagram shows the data flow from raw user input to the generation of a structured ComposerDraft used by the SDK.

Execution Visibility: PartView
The PartView component is responsible for rendering the diverse outputs of the AI agent, known as "Parts." It acts as a polymorphic renderer that handles text, reasoning, tool calls, file artifacts, and step status updates.
Supported Part Types
| Part Type | UI Representation | Features |
|---|---|---|
text | Markdown / Plain Text | Throttled rendering via marked with custom syntax highlighting. |
tool | Tool Execution Block | Shows tool name, status (running/completed), input/output, and diffs. |
reasoning | Collapsible "Thinking" | Hides complex model reasoning behind a developer-mode toggle. |
file | Artifact Card | Displays filename, MIME type, and provides click-to-open functionality. |

Context and Navigation
The ContextPanel and StatusBar components provide high-level environmental awareness, showing the state of active plugins, MCP servers, and workspace permissions.
Context Panel Sections
- Working Files: A list of files currently being modified or read by the agent, using a "Smart File Name" algorithm to differentiate duplicates in different directories.
- Skills & Plugins: Lists active extensions loaded from
.opencode/skillsoropencode.json. - MCP Status: Real-time connectivity status for Model Context Protocol servers (Connected, Failed, Needs Auth).

Button Component Implementation
The standard Button component provides a consistent visual language across the app, supporting multiple variants and states.
Sources: packages/app/src/app/components/button.tsx:1-45
// Example of Button variant logic
const variants = {
primary: "bg-gray-12 text-gray-1 hover:bg-gray-11",
secondary: "bg-gray-3 text-gray-12 hover:bg-gray-4 border border-gray-6",
outline: "bg-transparent text-gray-11 border border-gray-6 hover:border-gray-7 hover:text-gray-12",
danger: "bg-red-9 text-white hover:bg-red-10",
ghost: "bg-transparent text-gray-10 hover:bg-gray-3 hover:text-gray-12"
};

Conclusion
The Core UI Components of OpenWork prioritize transparency and responsiveness. By leveraging a modular architecture of specialized renderers (PartView) and rich input controllers (Composer), the system provides users with a clear audit trail and precise control over agentic workflows. This structure ensures that technical details (like MCP statuses and reasoning) are accessible but do not overwhelm the "calm" user experience intended for non-technical users.
