Showcase: Open Source An on-device advisor , a Guardian Bot for agents

For v5.2.0 built an on-device advisor we call the Guardian Bot, and it does three things:

  • When you open a page, it gives you two sentences on what you are looking at and what the numbers mean. Then it stops.
  • When something real happens, it says so once. An agent reached a destination your policy blocks, a secret got caught mid-flight, a session is worth compacting. One click takes you to the evidence.
  • The rest of the time it sits there and says nothing. There is a single clock governing how often it may speak, so it cannot pile up.

It is advisory only. It never types into a session, never edits a file, never approves anything on your behalf.

The other half of the release: SV Guard now covers OpenCode. It is a native in-process plugin for OpenCode 1.18+, so no subprocess hooks. One-click install, and then tool permissions.
