Is Pieces for Developers: Copilot & Code Capture safe?

Low risk

Pieces for Developers lets any website request stored Pieces identifiers and site history state through a page message bridge.

Its content scripts run on all URLs and respond to a page's contentInit postMessage without checking the sender. The response can include Pieces storage values such as user and OS server IDs, settings, history blocks, and site state lists, so a website script can read those values when present.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
