Enter the URL of your +Dispatch instance, approve the pairing request in Dispatch, return to the page +you want to inspect, and select a running agent. + +## Permissions and privacy + +The configured Dispatch origin is only the feedback destination. The extension +can inspect an unrelated HTTP or HTTPS site after the user explicitly invokes +the picker there. On first use, Chrome prompts the user to grant the extension +access to HTTP and HTTPS pages. This optional grant makes the picker reliable as +the side panel follows the user between projects and can be revoked at any time +from Chrome's extension settings. The inspected page never needs to share an +origin with Dispatch. Access to the configured Dispatch origin is requested +separately at pairing time. + +Before showing or sending the context preview, the extension removes form +values, editable content, scripts, inline event handlers, `srcdoc`, and likely +secret URL parameters. + +Each Chrome profile receives a separate 90-day, revocable token. The token is +stored only in extension-local storage and is restricted to trusted extension +contexts. Disconnecting removes the local token and the optional Dispatch host +permission. If the server cannot be reached to revoke the remote token, the +extension reports that explicitly; active connections can always be revoked +independently in Dispatch settings. + +HTTP Dispatch URLs are supported for self-hosted environments. Before pairing, +the extension requires an explicit acknowledgement that HTTP sends credentials +and feedback without transport encryption. HTTPS should be preferred on +untrusted networks. + +Chrome blocks script injection on browser-owned pages such as +`chrome://extensions` and the Chrome Web Store. After the user grants access to +HTTP and HTTPS sites, selection can inspect reachable open DOM in the top-level +page and in HTTP/HTTPS frames, including cross-origin frames where Chrome +permits extension injection. Frames Chrome refuses to inject into and closed +shadow roots are not inspected. + +## Release checks + +The manifest and package versions must match; an extension test enforces this. +Before packaging a release, run the repository checks and extension tests, then +run the package command above.
