Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no install lifecycle hook or concrete attack behavior. The scanner’s SSH persistence finding corresponds to an explicit, interactive setup flow, and the agent configuration migration is limited to a matching legacy RainSkills entry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-17T01:29:55.828Z - **Finished:** 2026-10-17T01:31:04.680Z - **Download time:** 765 ms - **Static scan time:** 789 ms - **AI review time:** 67297 ms - **Total time:** 68852 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No malicious attack surface was identified. The flagged remote key write is part of an interactive SSH setup for a host selected by the user. - **Trigger:** The user runs the separate SSH prepare command in an interactive system terminal. - **Impact:** This enables key-based login to that server; inspected source does not show an unrelated credential transfer or covert remote-access setup. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:31:04.680Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper sends the locally generated public key through SSH and adds it to the selected server’s authorized\_keys file. - **Rationale:** Source inspection found no install lifecycle hook or concrete attack behavior. The scanner’s SSH persistence finding corresponds to an explicit, interactive setup flow, and the agent configuration migration is limited to a matching legacy RainSkills entry. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI and build/check scripts; the inspected manifest has no npm install lifecycle hook., The local installer removes only a matching legacy RainSkills MCP entry from the named Rainbond configuration section., SSH setup requires an interactive terminal, uses a locally generated public key, and adds it to the user-selected server’s authorized\_keys., When SSH authentication is unavailable, the platform installer asks the user to run a separate SSH preparation command in their system terminal., The platform installer waits for confirmation of displayed effects before beginning installation. - **Evidence against:** The SSH helper writes a public key to remote authorized\_keys, which enables key-based access; source ties this to the explicit preparation flow for the selected host. ## Affected versions and remediation This report applies to rainskills@0.1.21. - Review the evidence and your use of rainskills@0.1.21 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.
