The installed skill supplies instructions that agents may act on later. - **Trigger:** npm installation with lifecycle scripts enabled - **Impact:** Unconsented persistence of package-authored instructions across installed AI-agent environments. - **Evidence paths:** package.json, scripts/postinstall.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T12:58:09.343Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-agent skill registration - **Attack narrative:** Installing the package executes postinstall, which detects several unrelated agent installations and writes the package's SKILL.md plus metadata into their skill directories. When no listed agent directory exists, it still creates ~/.agents/skills/tuniu-cli. This creates persistent, automatically activated agent instructions without an explicit user setup command. - **Rationale:** This is a concrete unconsented postinstall mutation of broad/foreign AI-agent control surfaces. The lack of installer exfiltration does not mitigate the persistence and control-surface 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, ~/.agents/skills/tuniu-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js on install., scripts/postinstall.js copies SKILL.md into detected ~/.claude, ~/.cursor, ~/.codex, ~/.openclaw and other agent skill directories., If none are detected, postinstall creates ~/.agents/skills/tuniu-cli without user action., SKILL.md contains operational Agent instructions, including preferred-skill priority and CLI installation/update commands. - **Evidence against:** postinstall uses only the package-local SKILL.md and no network request., No credential harvesting or exfiltration was found in the install script., Runtime API endpoints in config.example.json are Tuniu service endpoints and require an API key. ## Public findings ### 1.
