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 shows no npm install hook or automatic attack behavior. The flagged remote access change requires an explicit SSH setup command and an interactive session with the selected server; platform installation separately requires confirmation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T01:25:06.918Z - **Finished:** 2026-10-17T01:26:11.924Z - **Download time:** 764 ms - **Static scan time:** 945 ms - **AI review time:** 63295 ms - **Total time:** 65006 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 attack was identified. The flagged SSH key change is part of an explicitly invoked, interactive setup for a user-selected server. - **Trigger:** The user runs the SSH preparation command or starts platform installation. - **Impact:** The selected server accepts the user's SSH key for that account. The inspected source does not show this occurring during npm installation. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:26:11.924Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** SSH preparation uses the user's public key on the selected server; platform installation pauses for confirmation before applying proposed effects. - **Rationale:** The source shows no npm install hook or automatic attack behavior. The flagged remote access change requires an explicit SSH setup command and an interactive session with the selected server; platform installation separately requires confirmation. ### 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 has no install lifecycle hook; its scripts are build, check, version, and test tasks., The CLI routes SSH preparation only when the user invokes \`ssh prepare\` or \`ssh prepare-cluster\`., SSH key setup requires an interactive terminal, names the selected server, and installs the user's public key there., Platform installation records proposed effects and waits for confirmation before starting., The local CLI migration removes only a legacy RainSkills MCP entry; its installer runs during CLI configuration. - **Evidence against:** SSH setup appends a public key to the selected server's authorized\_keys, creating persistent access for the user's account., The local CLI installer can update the user's Codex and Claude configuration files. ## Affected versions and remediation This report applies to rainskills@0.1.23. - Review the evidence and your use of rainskills@0.1.23 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.
