Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.1.41 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The package has no npm install lifecycle hook, so the evidence does not establish an unconsented install-time attack. Its unverified remote bootstrap and explicit broad AI-agent/SSH mutation leave a concrete dangerous capability that warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-06T01:36:54.447Z - **Finished:** 2026-09-06T01:38:19.436Z - **Download time:** 754 ms - **Static scan time:** 1290 ms - **AI review time:** 82944 ms - **Total time:** 84989 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:** Explicit CLI or shell-installer use can alter AI-agent skill directories and local Rainbond runtime files. The shell path also downloads and executes an unverified latest archive, while a separate explicit SSH command adds a key to a remote account. - **Trigger:** A user runs rainskills, install.sh, or the ssh prepare subcommand. - **Impact:** A compromised download endpoint could run code during explicit installation; the package can also change selected agent capabilities and enable key-based access to a chosen server. - **Evidence paths:** install.sh, rainbond-platform-installer/scripts/host-targets.js, rainbond-platform-installer/scripts/windows-onboarding.js, rainbond-platform-installer/scripts/ssh-key-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-06T01:38:19.436Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote archive bootstrap plus AI-agent configuration and optional SSH key installation. - **Rationale:** The package has no npm install lifecycle hook, so the evidence does not establish an unconsented install-time attack. Its unverified remote bootstrap and explicit broad AI-agent/SSH mutation leave a concrete dangerous capability that warrants a warning. - **Files touched:** ~/.claude/skills, ~/.codex/skills, ~/.pi/agent/skills, ~/.dsh/skills, ~/.workbuddy-ai/skills, ~/.hermes/skills, ~/.rainbond/bin, ~/.rainbond/lib, $HOME/.ssh/authorized\_keys - **Network endpoints:** https://get.rainbond.com/rainskills/rainskills-latest.tar.gz ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The shell installer fetches a latest tarball from a network endpoint without an integrity check, extracts it, and executes its install script., The user-invoked installer writes bundled skills into several AI-agent skill directories and installs a local runtime bundle., The SSH preparation command appends a generated public key to the selected remote account’s authorized-keys file., The shell installer directly addresses AI assistants and instructs them how to invoke it. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The agent target must be supplied or selected interactively; non-interactive use without a target fails., The SSH routine requires an interactive terminal and a user-supplied SSH target., Telemetry is opt-out and the inspected event schema contains installation metadata rather than credentials. ## Affected versions and remediation This report applies to rainskills@0.1.41. - Review the evidence and your use of rainskills@0.1.41 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.
