Detail	Offsend Extension	Stroq
Overview	When working with AI tools, it's easy to accidentally share sensitive information, which can compromise security and privacy. Offsend Extension solves this problem by scanning user input locally and automatically masking sensitive data, giving users control over what information is shared and what remains private.	Stroq is an open‑source Agent Guard that runs on Node 22+ and inspects where a command originated before allowing it to execute. It normalizes tool output, tracks provenance of packages or URLs, and blocks outbound calls that contain indexed secrets, reporting the variable and file name. By hooking into Claude Code, Codex CLI, Cursor and similar agents, Stroq applies deterministic, model‑free policies and logs every decision, helping developers prevent secret leaks and unintended actions without sending data to external services.

Provenance: records the earlier tool output that introduced a package, URL or command fragment and reports it when later used. Secret Egress Guard: indexes secrets as salted hashes and denies any outbound call that includes a known secret, naming the variable and source file.
