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:** 1.17.0 - **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. Static source inspection shows a user-invoked AI-skill package manager with broad agent integration, not lifecycle-triggered hijacking or malware. Because it can install registry content into AI-agent control surfaces, warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-07-05T01:49:13.255Z - **Finished:** 2026-07-05T01:50:08.315Z - **Download time:** 258 ms - **Static scan time:** 1483 ms - **AI review time:** 53318 ms - **Total time:** 55060 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 confirmed malicious install/import-time attack surface. The package is an explicit CLI package manager for AI-agent skills and can write symlinks/config into agent skill directories when the user runs install/setup/agents commands. - **Trigger:** User-invoked happyskills CLI commands such as install, setup, agents, self-update, or login - **Impact:** User-selected registry skills may become visible to configured AI agents; no unconsented lifecycle mutation was found. - **Evidence paths:** package.json, bin/happyskills.js, src/index.js, src/engine/installer.js, src/agents/registry.js, src/agents/detector.js, src/agents/linker.js, src/commands/setup.js, src/commands/self-update.js, src/api/client.js, src/utils/scrub\_secrets.test.js - **Review source:** ai\_review - **Reviewed:** 2026-07-05T01:50:08.315Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package-aligned AI skill installation and agent-directory linking - **Rationale:** Static source inspection shows a user-invoked AI-skill package manager with broad agent integration, not lifecycle-triggered hijacking or malware. Because it can install registry content into AI-agent control surfaces, warn rather than block. - **Files touched:** .agents/skills/, skills-lock.json, skills-config.json, .claude/skills/, .cursor/skills/, .codex/skills/, ~/.config/happyskills/credentials.json - **Network endpoints:** https://api.happyskills.ai, https://registry.npmjs.org/happyskills/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** src/engine/installer.js downloads registry skills and links them into agent skill directories., src/agents/registry.js targets broad AI-agent surfaces including .claude/skills, .cursor/skills, and .codex/skills., src/agents/detector.js defaults to Claude Code when no agent is configured, but only during user-invoked commands., src/commands/setup.js installs happyskillsai/happyskills into agent skills on explicit setup., src/commands/self-update.js can run npm install -g happyskills@latest only when self-update is invoked. - **Evidence against:** package.json has no preinstall/postinstall/prepare lifecycle scripts., bin/happyskills.js only loads dotenv from the package .env and dispatches CLI args., src/index.js command loading is constrained by a fixed COMMANDS allowlist., Network traffic is package-aligned to https://api.happyskills.ai and npm registry update checks., Secret-looking strings in src/utils/scrub\_secrets.test.js are synthetic redaction fixtures., No evidence of credential harvesting, persistence hooks, destructive behavior, eval, or install-time agent mutation. ## Affected versions and remediation This report applies to happyskills@1.17.0. - Review the evidence and your use of happyskills@1.17.0 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.
