plain.upgrade

Upgrade Plain packages using AI agents.

The plain-upgrade command can be run using uvx (part of the uv package manager) and will update the Plain packages in your project, then prompt an AI agent to run any additional upgrade steps for each package.

The recommended way to use it is to define your preferred LLM/AI agent command either in your personal shell configuration (ex. .zshrc or .bashrc) or in your project (ex. .env).

export PLAIN_UPGRADE_AGENT_COMMAND="codex --model o3 --flex-mode --auto-edit"

Updating Plain is then as simple as running:

uvx plain-upgrade

Note that this command only supports uv currently. Run uvx plain-upgrade --help for more options.
