SF Documentation
Welcome to the SF documentation. SF is a purpose-to-software compiler: it turns bounded intent into PDD contracts, researches missing context, writes failing tests or executable evidence first, implements the smallest satisfying change, and records verification. See ADR-0000 and Spec-First TDD before changing product behavior.
This index covers everything from getting started to advanced configuration, autonomous mode internals, and extending SF with the Pi SDK.
User Documentation
Guides for installing, configuring, and using SF day-to-day. Located in user-docs/.
| Guide | Description |
