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. The source ties the flagged SSH key write to an interactive, user-invoked setup command and limits it to the selected host. The inspected package manifest and installer code do not support the scanner’s malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T01:30:24.437Z - **Finished:** 2026-10-17T01:31:05.016Z - **Download time:** 510 ms - **Static scan time:** 937 ms - **AI review time:** 39131 ms - **Total time:** 40579 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 confirmed attack surface was identified in the inspected source. The flagged persistence behavior is an explicit SSH setup feature, and Windows installation is gated by confirmation and download-origin checks. - **Trigger:** A user must invoke SSH preparation in an interactive terminal or confirm the Windows installation flow. - **Impact:** These actions support the requested setup flows; the inspected source does not establish unauthorized access or other concrete attack behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:31:05.016Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** SSH preparation installs the user’s public key on the selected host; the Windows installer checks approved HTTPS origins for artifacts and redirects. - **Rationale:** The source ties the flagged SSH key write to an interactive, user-invoked setup command and limits it to the selected host. The inspected package manifest and installer code do not support the scanner’s malicious verdict. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI and lists build, check, and packaging scripts; I found no install lifecycle hook., The SSH key setup is routed through an explicit CLI command, requires an interactive terminal, and adds a public key to the selected host’s authorized keys., The local installer only removes a matching legacy Rainbond MCP entry from Codex configuration when run; it leaves other sections intact., The Windows installer requires confirmation before enabling WSL and restricts artifact downloads and redirects to allowed HTTPS origins. - **Evidence against:** The flagged SSH key write is part of an interactive, user-invoked setup flow, not an automatic package-install action., The inspected installer behavior does not establish credential theft, an unauthorized persistent backdoor, or an attack on unrelated agent configuration. ## Affected versions and remediation This report applies to rainskills@0.1.11. - Review the evidence and your use of rainskills@0.1.11 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.
