durable_agent

Crash-safe, resumable AI agent conversations for Rails. The gem ships pi-durable as a bundled sidecar process that keeps its state in your app's own database, Postgres or SQLite, which Rails reads with Active Record. Tools are Ruby classes. Pages update over Turbo.

bundle add durable_agent
bin/rails g durable_agent:install   # migration, initializer, mount, Procfile.dev line
bin/rails db:migrate
bin/dev                             # web, sidecar

conversation = DurableAgent.start
conversation.say("Summarize the invoice", request_id: message.id)
conversation.transcript
