Pi Coding Agent Browser by Mathieu Gosbee

0.1.1 — initial release

Pi Browser is a sidebar add-on that runs the Pi Coding Agent locally on
your machine and lets it operate the current browser tab.

Features:
- Multi-session ACP chat in the sidebar: start, switch between, and close
agent sessions; sessions persist across browser restarts (browser.storage).
- Browser tools for the agent: the add-on exposes the bound tab to the
agent — navigate, click, fill, evaluate JS, read page content, and
screenshot (also available as the toolbar "Pi Screenshot" action).
- Local-by-design: the agent runs on your computer through a small native
messaging host (com.matbee.agent). No backend, no telemetry, no data
collection — the manifest declares data_collection_permissions: none.
- Auto-connect: the sidebar detects the native host on its own (no reload
needed) and shows clear onboarding when it is missing
("run /pi-browser install").

Requirements:
- Firefox 126 or later.
- Node.js with the Pi Coding Agent installed (npm: @earendil-works/pi-coding-agent)
and a configured model (e.g. an Anthropic API key).
- One-time native host registration: /pi-browser install inside a Pi
session (Linux, macOS, and Windows supported).
