This is an embeddable browser SDK that contacts a Pluno product-agent backend only after the host application imports it. - **Trigger:** The host application imports the SDK or widget. There is no npm install hook. - **Impact:** No install-time mutation, hidden credential harvest, persistence, or unrelated exfiltration was identified. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T06:07:08.245Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Requests use the configured backend URL, defaulting to https://app.pluno.ai. Optional page JavaScript runs only for an execute\_code tool call. - **Rationale:** The published entrypoints are a browser product-agent SDK, widget, and runtime client with no install-time execution. Network use and page code execution are host-invoked and aimed at the configured Pluno backend. - **Network endpoints:** https://app.pluno.ai ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has build, check, test, and prepack scripts only, with socket.io-client as the sole runtime dependency and no install lifecycle hook., The SDK and widget default their backend to https://app.pluno.ai and send product-agent HTTP and websocket traffic to the caller-configured backend URL., Browser JavaScript runs only after the host app loads the SDK, through an AsyncFunction used for the execute\_code tool., The CommonJS runtime bundle is client session and display state code and does not open network connections or spawn processes. - **Evidence against:** execute\_code can run backend-supplied JavaScript in the embedding page, which is powerful but matches an embedded product-agent widget the host app chooses to load., A sandbox-files bearer token from the runtime context is sent only to the configured backend attachment routes during that code execution. ## Affected versions and remediation This report applies to @pluno/product-agent-web@0.1.304. - Review the evidence and your use of @pluno/product-agent-web@0.1.304 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
