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 persistence hint corresponds to an interactive SSH setup that installs a generated public key on the host selected by the user. The manifest has no npm install lifecycle hook, and the reviewed local CLI migration is limited to legacy RainSkills configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-17T01:24:58.826Z - **Finished:** 2026-10-17T01:29:05.480Z - **Download time:** 1012 ms - **Static scan time:** 806 ms - **AI review time:** 244836 ms - **Total time:** 246654 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 reviewed SSH key write and local CLI configuration migration are scoped installer behavior. - **Trigger:** SSH key setup runs when its explicit prepare command is invoked in an interactive terminal; platform installation requires confirmation unless --yes is supplied. - **Impact:** The SSH flow enables the requested identity to connect to the selected host; inspected source does not show an undisclosed recipient or broader persistence behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:29:05.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SSH flow uses a caller-selected host and generated public key to configure remote access. The local migration handles legacy RainSkills MCP entries in supported user configuration files. - **Rationale:** The persistence hint corresponds to an interactive SSH setup that installs a generated public key on the host selected by the user. The manifest has no npm install lifecycle hook, and the reviewed local CLI migration is limited to legacy RainSkills configuration. - **Files touched:** rainbond-platform-installer/scripts/ssh-key-setup.js, rainbond-platform-installer/scripts/platform-installer.js, scripts/install-local-cli.mjs, package.json, ~/.ssh/authorized\_keys ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the command through bin/rainskills.js; its scripts are build and development tasks, not npm install hooks., The required location in scripts/install-local-cli.mjs reads a safe Codex config and splits it into sections before migration., The local installer copies its runtime into the user’s .rainbond directory and removes only legacy RainSkills MCP entries from supported configs., SSH preparation requires an interactive terminal and a caller-specified target; the code warns that host confirmation and a server password may be required., The SSH command sends the generated public key to that target and adds it to the remote user’s authorized\_keys file., The platform installer prompts for confirmation before beginning a Rainbond installation unless the caller explicitly uses --yes. - **Evidence against:** ssh-key-setup.js writes a public key to remote authorized\_keys, which creates continuing access; source shows this is the explicit SSH preparation flow for the selected host. ## Affected versions and remediation This report applies to rainskills@0.1.27. - Review the evidence and your use of rainskills@0.1.27 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.
