+magenta.nvim is a plugin for agent-assisted LLM development in neovim.
+
+Rather than writing complex code to automatically provide context to the LLM, magenta is built around the idea that you
+can just expose tools to the LLM and have it decide what it needs to do.
+
+The initial offering will start with basic tools:
+
+- get_file
+- list_directory
+- edit file
+- run terminal command
+
+Eventually I'd like to add more advanced tools:
+
+- list symbols for file
+- list diagnostics
+- get definition or "summary" info for a symbol
+- find symbol references
+
+The general idea is that some of these will be automated and not require user intervention, while others will require
+user approval. (for example, getting the type definition of a symbol may be automated, while reading a dotfile will require
+user permission).
+
+I'm also hoping to eventually implement an inline diff / edit confirmation system like windsurf or avante.
+
+This project is still in its early days and this is my first neovim plugin so it will probably be a while until it's useful to anyone. But I am investing some time in building a robust framework and testing system so that
+it is easier to contribute to in the future. If you'd like to help, please reach out. You can find my contact info at my blog - dlants.me
