Install

Local (no install)

pi -e /absolute/path/to/pi-dynsys

pi install git:github.com/<you>/pi-dynsys
# or

Pi installs packages into its settings and loads extensions automatically.

Auth / secrets

This repo contains no API keys.

Provider credentials are handled by Pi and stored outside the repo (e.g. ~/.pi/agent/auth.json or env vars). Do not commit those files.

Using openai-codex

The dynsys generator is configured to call a nested pi process with:

• provider: openai-codex
• model: gpt-5.2-codex
• thinking: off

You must be authenticated for openai-codex (Pi interactive):

• Run pi then /login and pick ChatGPT Plus/Pro (Codex).

Flags

• --dynsys (default: true)
• --dynsys-debug (writes ~/.pi/agent/dynsys-last.json)

Example:

pi -p --dynsys-debug "UI: design a button component, no gradients"
