This article details the updates to agent-shell version 0.47.1, a native Emacs mode for interacting with LLM agents powered by ACP. Key improvements include renaming 'claude-code-acp' to 'claude-agent-acp', support for new agents like Auggie, Cline, and GitHub Copilot, and experimental bootstrapped and resumable sessions. Enhancements have also been made to clipboard image handling, status display, image rendering, and table rendering. The update also introduces usage tracking, improved diffs, event subscriptions, and customizable context sources. The author encourages sponsorship to ensure the project's sustainability.
A workflow for rapidly building applications with GitHub Copilot CLI, emphasizing its role in generating *momentum* and quickly reaching a reviewable pull request. Leverage Copilot CLI for speed, your IDE for refinement, and GitHub for collaboration.
* **Define & Scaffold:** Start with a natural language description of your goal and use Copilot CLI to scaffold only the parts you're ready to actively work on.
* **Iterate & Refine:** Run tests and use Copilot CLI to help understand and fix failures; handle mechanical, repo-wide changes with the CLI.
* **Develop & Ship:** Transition to your IDE for complex logic/design, then commit your changes and create a pull request on GitHub for collaboration.
* The Copilot SDK offers possibilities for embedding agentic execution directly within applications.
