# Pile Protocol

Open protocol for agent-to-human decision capture.

When an AI agent needs a human decision, the Pile Protocol gives it a review screen and sends back structured instructions it can act on. One link. Mark it. Agent continues.

## What this repo will hold

- Pile Protocol spec (versioned)
- Resolution payload schema
- Conformance test suite
- Example resolutions across decision types

## Status

**v0.0.0 placeholder.** Spec drafting in progress. Full v0.1 RFC publishes alongside the hosted product launch.
