The package gains unconsented influence over installed AI agents and can direct them to install or update this CLI. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.1.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Npm installation automatically writes a package-controlled skill into multiple third-party AI-agent directories. It creates a fallback agent skill directory even when no supported agent is detected. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T06:59:20.322Z - **Finished:** 2026-08-28T07:00:18.681Z - **Download time:** 250 ms - **Static scan time:** 716 ms - **AI review time:** 57392 ms - **Total time:** 58359 ms ## Security analysis ### Published attack-surface review - **Summary:** Npm installation automatically writes a package-controlled skill into multiple third-party AI-agent directories. It creates a fallback agent skill directory even when no supported agent is detected. - **Trigger:** Installing tuniu-cli with npm lifecycle scripts enabled. - **Impact:** The package gains unconsented influence over installed AI agents and can direct them to install or update this CLI. - **Evidence paths:** package.json, scripts/postinstall.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T07:00:18.681Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies a bundled AI-agent skill into home-directory control surfaces. - **Attack narrative:** During npm postinstall, the package detects several unrelated AI-agent home directories and writes its SKILL.md plus metadata into them without a user command or consent. If none exist, it creates ~/.agents/skills/tuniu-cli. The installed instructions tell an agent to automatically globally install tuniu-cli when absent, creating a persistence and propagation path through agent control surfaces. - **Rationale:** This is an unconsented postinstall mutation of broad, foreign AI-agent control surfaces. The local-only copy and integrity check do not remove that install-time control hijack. - **Files touched:** scripts/postinstall.js, SKILL.md, ~/.claude/skills/tuniu-cli/SKILL.md, ~/.cursor/skills/tuniu-cli/SKILL.md, ~/.codex/skills/tuniu-cli/SKILL.md, ~/.config/opencode/skills/tuniu-cli/SKILL.md, ~/.openclaw/skills/tuniu-cli/SKILL.md, ~/.agents/skills/tuniu-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall script automatically during npm installation., The postinstall script targets skill directories for Claude, Cursor, Codex, OpenCode, and other agents., It copies its bundled SKILL.md and writes metadata into those agent control directories., If no agent directory exists, it still creates and writes to ~/.agents/skills/tuniu-cli., The installed skill directs an agent to automatically run a global npm installation when the CLI is absent. - **Evidence against:** The postinstall code copies a bundled local file and makes no network request., The script checks the bundled skill hash when a packaged hash manifest is present., The runtime service endpoints are package-aligned Tuniu APIs, but they do not mitigate install-time agent mutation. ## Public findings ### 1.
