Condukt is an Elixir framework for building agents that do real work on your infrastructure.

Its source lives in condukt/ in the Tuist monorepo. It remains independently published as condukt on Hex.

The agent loop is the easy part of that and the least of what this gives you. Every session is a supervised process whose tools run in a sandbox, on a network you decide, with secrets it never gets to print:

• Sandboxes so tools run somewhere other than your filesystem: in memory, in a microVM, or in a dedicated Kubernetes pod per session, behind one interface.
• Network policy per session, audited and enforced outside the agent, with allow and deny rules by host and a decider agent for the cases a rule cannot settle.
• Secrets resolved separately from the conversation and redacted from transcripts.
• OTP doing what it is good at: supervision, streaming, backpressure, cancellation, and sub-agents as children with typed inputs and outputs.

Agents are the imperative half of the picture. They compose with a declarative workflow engine rather than replacing one: let the workflow own the steps you can name, and give an agent the ones you cannot.

Library

Use Condukt when agents should live inside your OTP system. Add it to mix.exs:

def deps do
  [
    {:condukt, "~> 1.5"}
  ]
end

defmodule MyApp.ProjectAgent do
  use Condukt

  @impl true
  def model, do: "anthropic:claude-sonnet-4-20250514"

  @impl true
  def system_prompt do
    "You help maintain this repository. Prefer concrete findings and patches."
  end

  @impl true
  def tools, do: Condukt.Tools.coding_tools()

  operation :release_notes,
    input: %{
      type: "object",
      properties: %{version: %{type: "string"}},
      required: ["version"]
    },
    output: %{
      type: "object",
      properties: %{
        title: %{type: "string"},
        highlights: %{type: "array", items: %{type: "string"}}
      },
      required: ["title", "highlights"]
    },
    instructions: "Draft release notes from the git history and project files."
end
