It represents a significant step in evolving his popular <code>llm</code> library into a capable, tool-wielding agentic framework.</p> <h2 id="posts">Posts<a class="anchor" href="#posts">#</a></h2> <p><strong><a href="https://simonwillison.net/2026/Jul/2/llm-coding-agent/#atom-everything">llm-coding-agent 0.1a0</a></strong> Simon released a new alpha tool that turns his <code>llm</code> library into a full-fledged coding agent. By prompting Claude Fable 5 in Claude Code to write the spec and build it via test-driven development, he shipped a CLI that includes file manipulation and command execution tools like <code>edit_file</code> and <code>execute_command</code>. He also highlights a neat Python API (the <code>CodingAgent</code> class) the AI implemented unprompted, and shared a successful test run where the agent built a SwiftUI ASCII time app using <code>llm code --yolo</code>.</p>
