What it is
CodeCompanion.nvim is a Neovim plugin that provides AI coding assistance and agent workflows. It includes built-in support for Agent Client Protocol (ACP) and Model Context Protocol (MCP), and adapters for multiple AI providers (e.g., OpenAI, Claude, Gemini, Copilot) and various tooling ecosystems. The repository describes features such as code reviews, inline transformations, editor context, slash commands, and workflows to improve LLM output.
How it works
The project integrates with Neovim and exposes integrations through adapters to external AI providers and agents. It offers features like code reviews, inline transformations, prompt libraries, and support for multiple chats and input modalities (including images and PDFs). It also supports various tooling and agent ecosystems via ACP/MCP support and adapters.

The repository README includes a sample configuration fragment for enabling logging in the plugin with different package managers:
-- lazy.nvim
{
"olimorris/codecompanion.nvim",
dependencies = {
"nvim-lua/plenary.nvim",
"nvim-treesitter/nvim-treesitter",
},
opts = {
-- NOTE: The log_level is in `opts.opts`
opts = {
log_level = "DEBUG", -- or "TRACE"
},
},
},
-- Other package managers
require("codecompanion").setup({
opts = {
log_level = "DEBUG", -- or "TRACE"
}
})
For troubleshooting, it suggests running :checkhealth codecompanion and enabling debug logging via configuration.
