How do I customize the system prompt for :CodeCompanionChat?

[jergason]

I have my own system prompt I like to use with llms in general. I'm confused about how to thread it in to codecompanion. How can I provide my own system prompt? For context, I'm using the Anthropic adapter. My setup basically looks like this:

require("codecompanion").setup({
  adapters = {
    anthropic = function()
      return require("codecompanion.adapters").extend("anthropic", {
        env = {
          api_key = "ANTHROPIC_AI_KEY"
        },
      })
    end,
  },
})

I am confused by the interaction between custom prompts, strategies, etc. I just want to use the normal :CodeCompanionChat functionality, but with my own system prompt. Is that possible?

Ah HAH, I missed it when reading the full config options. This did the trick:

require("codecompanion").setup({
  adapters = {
    anthropic = function()
      return require("codecompanion.adapters").extend("anthropic", {
        env = {
          api_key = "ANTHROPIC_AI_KEY"
        },
      })
    end,
  },
  opts = { system_prompt = "MY SUPER COOL SYSTEM PROMPT" },
})
