Pi

Lets bakers.build run tickets with the pi coding CLI.

For anyone whose machine should run tickets with pi.

Enable it

Add the package to addons in ~/.bakers/machine.config.js; agent harnesses may be listed only there. Keep the other fields there.

addons: ['@bakers-build/addon-pi'],

It publishes one alias, pi, which uses your locally configured pi model.

Options

Option	Type	Default	Effect
model	string	pi's own default	Passed as --model.
provider	string	none	Passed as --provider.
thinking	string	none	Passed as --thinking.
effort	string	none	Same as thinking, and wins over it.
approve	boolean	false	Passes --approve: trusts the worktree's project-local pi files. Grants no bakers.build access.
args	string[]	[]	Extra arguments, each shell-quoted.

Check it works

The agent catalog lists pi with harness pi.

Per CLI

Good to know

• pi has no tool-permission gate, so leave approve off unless a run needs project-local pi files.
• --session-dir, --approve, -a, --no-approve and -na are reserved; putting them in args fails loading.
• The addon starts pi; it does not install it or sign it in. The binary must be on PATH.
• Listed in a conductor config, an agent addon is ignored with a warning.
