Run Aider AI pair programming in your workspace. This module installs Aider with AgentAPI for seamless Coder Tasks Support.

variable "api_key" {
  type        = string
  description = "API key"
  sensitive   = true
}

module "aider" {
  source      = "registry.coder.com/coder/aider/coder"
  version     = "2.0.0"
  agent_id    = coder_agent.example.id
  api_key     = var.api_key
  ai_provider = "google"
  model       = "gemini"
}

Prerequisites

• pipx is automatically installed if not already available

Usage Example

data "coder_parameter" "ai_prompt" {
  name        = "AI Prompt"
  description = "Write an initial prompt for Aider to work on."
  type        = "string"
  default     = ""
  mutable     = true
}

variable "gemini_api_key" {
  type        = string
  description = "Gemini API key"
  sensitive   = true
}

module "aider" {
  source           = "registry.coder.com/coder/aider/coder"
  version          = "2.0.0"
  agent_id         = coder_agent.example.id
  api_key          = var.gemini_api_key
  install_aider    = true
  workdir          = "/home/coder"
  ai_provider      = "google"
  model            = "gemini"
  install_agentapi = true
  ai_prompt        = data.coder_parameter.ai_prompt.value
  system_prompt    = "..."
}

Using a custom provider

variable "custom_api_key" {
  type        = string
  description = "Custom provider API key"
  sensitive   = true
}

module "aider" {
  count               = data.coder_workspace.me.start_count
  source              = "registry.coder.com/coder/aider/coder"
  version             = "2.0.0"
  agent_id            = coder_agent.example.id
  workdir             = "/home/coder"
  ai_provider         = "custom"
  custom_env_var_name = "MY_CUSTOM_API_KEY"
  model               = "custom-model"
  api_key             = var.custom_api_key
}

Troubleshooting

• If aider is not found, ensure install_aider = true and your API key is valid
• Logs are written under /home/coder/.aider-module/ (install.log, agentapi-start.log) for debugging
• If AgentAPI fails to start, verify that your container has network access and executable permissions for the scripts
