It installs a package-provided instruction file without an explicit user command. - **Trigger:** npm installation with lifecycle scripts enabled - **Impact:** Affected agents may load package-controlled instructions and be directed to install or update this CLI. - **Evidence paths:** package.json, scripts/postinstall.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-14T03:44:00.222Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies SKILL.md into detected agent directories or ~/.agents fallback - **Attack narrative:** Installing the package invokes postinstall. The script detects several independent AI-agent directories and copies the bundled skill into each; when none exist, it creates a generic ~/.agents skill. This is an unconsented install-time mutation of foreign and broad agent control surfaces, making the package's instructions available to those agents. - **Rationale:** Source directly confirms automatic, cross-agent skill installation during npm postinstall. This meets the blocking policy regardless of the absence of network activity in that lifecycle script. - **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, ~/.agents/skills/tuniu-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., Postinstall targets multiple unrelated AI-agent skill directories., It copies bundled SKILL.md into each detected agent directory., If none are detected, it creates ~/.agents/skills/tuniu-cli. - **Evidence against:** Postinstall does not make network requests or execute a downloaded payload., Writes are limited to the package-named skill and metadata files. ## Public findings ### 1.
