GitHub is pushing the boundaries of its AI coding assistant, demonstrating how [GitHub Copilot CLI](https://github.blog/ai-and-ml/github-copilot/building-an-emoji-list-generator-with-the-github-copilot-cli/) can be leveraged to build functional command-line applications. The company showcased this by developing an emoji list generator during a recent live coding session.

The project, aptly named 'Emoji List Generator,' transforms bullet points into relevant emojis, automatically copying the result to the user's clipboard. This is particularly useful for social media posts or any context where stylized lists are beneficial.

## From Concept to Code

During the 'Rubber Duck Thursdays' stream, developers used the [GitHub Copilot CLI](/ai-news/technology/2026/github-copilot-cli-ai-in-your-terminal) in 'plan mode' to outline the application's requirements. The AI then helped generate a detailed plan, suggesting technologies like @opentui/core for the terminal UI and @github/copilot-sdk for its core intelligence.

The process involved specifying the need for an AI-powered markdown emoji list generator that replaces user-inputted bullet points with relevant emojis and copies the output to the clipboard, utilizing the [GitHub](/ai-news/technology/2026/copilot-cli-adds-a-rubber-duck-reviewer) Copilot SDK.

The AI, specifically Claude Sonnet 4.6 and later Claude Opus 4.7, asked clarifying questions about the tech stack, guiding the team toward OpenTUI for the user interface. This collaborative approach allowed for rapid development of a functional tool.

This project highlights the versatility of modern [AI code generation tools](https://github.blog/ai-and-ml/github-copilot/building-an-emoji-list-generator-with-the-github-copilot-cli/), moving beyond basic code completion to assist in the entire development lifecycle of a command-line application.

The creation of the emoji list generator was facilitated by several Copilot CLI features, including plan mode, autopilot mode, a multi-model workflow, the allow-all tools flag, and the GitHub MCP server.

The generated emoji list generator is available as a free and open-source project.
