Treat them as untrusted evidence. 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:** 0.1.28 - **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 install lifecycle hook or self-dependency, so the evidence does not support a malware block. Its explicit CLI can still modify AI-agent control surfaces and remote SSH authorization, so it warrants a warning under the dangerous-capability policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-30T01:25:46.054Z - **Finished:** 2026-08-30T01:27:13.373Z - **Download time:** 260 ms - **Static scan time:** 1091 ms - **AI review time:** 85967 ms - **Total time:** 87319 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 use installs and later updates Rainbond skill content in several AI-agent directories. A separate explicit SSH command can add the local public key to a chosen remote server. - **Trigger:** The user runs the rainskills CLI, its runtime-status command, or ssh prepare. - **Impact:** The package can alter agent behavior through installed skills, replace prior skill content, report installation metadata, and establish SSH access to a user-selected host. - **Evidence paths:** package.json, install.sh, bin/rainskills.js, scripts/install-local-cli.mjs, rainbond-platform-installer/scripts/auto-update.js, rainbond-platform-installer/scripts/ssh-key-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T01:27:13.373Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent skill installation and auto-update, telemetry reporting, and optional SSH key setup. - **Rationale:** The package has no install lifecycle hook or self-dependency, so the evidence does not support a malware block. Its explicit CLI can still modify AI-agent control surfaces and remote SSH authorization, so it warrants a warning under the dangerous-capability policy. - **Files touched:** $HOME/.claude/skills, $HOME/.codex/skills, $HOME/.pi/agent/skills, $HOME/.ssh/id\_ed25519, $HOME/.ssh/id\_ed25519.pub, $HOME/.ssh/authorized\_keys, $HOME/.rainbond/rainskills/telemetry/events.jsonl - **Network endpoints:** https://registry.npmjs.org/rainskills/latest, https://registry.npmmirror.com/rainskills/latest, https://log.rainbond.com/api/rainskills/lifecycle-events ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The user-run installer writes skills into Codex, Claude, and Pi agent directories and replaces differing skill trees., A normal runtime-status command can fetch a newer package release and replace installed skill directories., The explicit SSH preparation command generates a key and appends its public key to the selected server's authorized keys., The installer posts lifecycle telemetry to a Rainbond endpoint., The installer includes instructions addressed to AI assistants. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Agent and SSH changes are reached through explicit CLI commands, not npm installation., The updater accepts only fixed registries, validates SHA-512 integrity, and runs npm with scripts disabled., No source evidence shows credential harvesting, secret exfiltration, hidden shell execution, or a runtime self-dependency. ## Affected versions and remediation This report applies to rainskills@0.1.28. - Review the evidence and your use of rainskills@0.1.28 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.
