Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is not an automatic install-time compromise, but it combines broad agent configuration changes, unchecked remote bootstrap code, and remote-access provisioning. The explicit AI-directed installation text is reviewer manipulation under policy, so the package warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-12T14:18:56.934Z - **Finished:** 2026-09-12T14:20:08.748Z - **Download time:** 510 ms - **Static scan time:** 854 ms - **AI review time:** 70449 ms - **Total time:** 71814 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:** Running the installer can modify AI-agent skill directories. Its explicit SSH preparation command can establish passwordless access to a selected remote host, and the bootstrap can execute a downloaded replacement archive. - **Trigger:** A user runs install.sh or the rainskills SSH preparation command. - **Impact:** It can change agent behavior, establish remote access, or execute code from a configured download URL. - **Evidence paths:** install.sh, rainbond-platform-installer/scripts/ssh-key-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T14:20:08.748Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-agent skill installation, remote SSH key provisioning, and unchecked archive bootstrap. - **Rationale:** This is not an automatic install-time compromise, but it combines broad agent configuration changes, unchecked remote bootstrap code, and remote-access provisioning. The explicit AI-directed installation text is reviewer manipulation under policy, so the package warrants a warning rather than a block. - **Files touched:** install.sh, $HOME/.claude/skills, $HOME/.codex/skills, $HOME/.pi/agent/skills, $HOME/.ssh/id\_ed25519, $HOME/.ssh/authorized\_keys - **Network endpoints:** https://get.rainbond.com/rainskills/rainskills-latest.tar.gz, https://github.com/goodrain/rainskills/archive/refs/heads/main.tar.gz, https://log.rainbond.com/api/rainskills/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The installer directly addresses AI assistants and directs them to recommend its installation command., An explicitly invoked installer copies bundled skills into several AI-agent configuration directories and replaces changed skill directories., The bootstrap accepts an environment-controlled tarball URL, downloads it, extracts it, and executes its install script without an integrity check., The SSH preparation command creates a key pair and appends its public key to a remote account's authorized\_keys file. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Agent-directory changes occur only when the user runs the installer and selects a target., SSH preparation requires an interactive terminal and announces the remote key installation., The inspected telemetry sender posts event data; no credential value is included in the cited event construction. ## Affected versions and remediation This report applies to rainskills@0.1.42. - Review the evidence and your use of rainskills@0.1.42 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.
