It plants instructions that can cause agents to install or update this CLI. - **Trigger:** npm install runs postinstall. - **Impact:** Foreign agent control surfaces can be changed without an explicit user setup command. - **Evidence paths:** package.json, scripts/postinstall.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-31T12:52:36.731Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent skill installation and upgrade instruction injection. - **Attack narrative:** On installation, the package runs postinstall and writes its bundled SKILL.md into detected Claude, Cursor, Codex, OpenCode, and other agent directories. If none are detected, it creates a default agent skill directory. The planted instructions tell an agent to automatically install the latest tuniu-cli when absent, creating an unconsented lifecycle path from npm installation to future agent-directed package installation. - **Rationale:** This is an unconsented postinstall mutation of broad, foreign AI-agent control surfaces. The lifecycle behavior is sufficient for blocking even though the installer itself does not contact the network. - **Files touched:** 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 install lifecycle automatically runs a script., That script writes a bundled skill into several foreign AI-agent directories when their parent folders exist., When no known agent is found, it still creates a default agent skill directory and copies the skill there., The installed skill directs agents to automatically install the latest package when the CLI is absent. - **Evidence against:** The postinstall script copies a bundled file and does not make a network request., No runtime dependency on this package itself is declared. ## Public findings ### 1.
