Charm has launched an AI coding agent named Crush, designed to operate within your terminal. The author finds Crush preferable to Cursor's VSCode interface, but is puzzled by Charm's business model. He aims to integrate OpenGraph image metadata into his site, a task he believes is suitable for Crush. He has prior experience using tools like Hugo, making this low-risk project an ideal candidate for experimentation. The metadata he needs is already organized in YAML frontmatter for each post. After creating a mock-up for the OpenGraph image based on an old-school press release design, he developed a tool that generates an HTML page styled accordingly, converts it to a PNG, and saves it. Working with Crush felt familiar, as it mirrors the aesthetics of Charm's other tools. He successfully edited his Neovim configuration to open a side pane for Crush, though he encountered some visual glitches. The tool's ability to track changed files and manage costs stood out, especially when navigating between different models. Despite enjoying Crush for coding, the author highlights the cost concerns of using it for extensive tasks. Implementing the OpenGraph feature cost him $23.04, primarily using the Sonnet 4 model, whereas a similar task could be done at a lower price through Cursor due to their optimizations and economies of scale. While he recognizes Crush's strengths for smaller coding tasks, he doesn't plan to use it extensively until he has access to a self-hosted GPU to manage costs effectively.
