It installs cross-agent skills/rules and weakens Claude Code command approval settings. - **Trigger:** npm installation - **Impact:** AI agents can be redirected into package-controlled workflows with broad preapproved shell commands; project files are also modified and evidence directories deleted. - **Evidence paths:** package.json, dist/postinstall.js, dist/steps/setupProject.js, dist/core/claudeCodePermissions.js, dist/core/installHygiene.js, src/templates/skills/confluence-doc.py.template, src/templates/skills/version-trigger.SKILL.md.template, src/templates/rules/sdd-no-implement-until-apply.mdc.template - **Review source:** ai\_review - **Reviewed:** 2026-08-09T01:06:59.525Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven cross-agent configuration mutation - **Attack narrative:** Installing the package runs postinstall automatically. That hook identifies the consumer project and writes package-controlled skills into four agent ecosystems, installs an always-apply Cursor rule, and merges broad Bash permissions into Claude Code settings. The same install path changes project metadata, copies scripts, and deletes existing evidence artifacts. A generated documentation script also contains default authentication material for an external Confluence service. - **Rationale:** This is a concrete unconsented postinstall mutation of broad, foreign AI-agent control surfaces, matching the block boundary. The lack of an install-time network call does not mitigate that control-hijack behavior. - **Files touched:** package.json, .cursor/skills/\*\*, .claude/skills/\*\*, .codex/skills/\*\*, .openclaw/skills/\*\*, .cursor/rules/00-sdd-flow-kit-version-trigger.mdc, .cursor/rules/sdd-flow-kit-gates.mdc, .claude/settings.local.json, .opsx/config.json, .sdd-flow-kit/setup-summary.md, .gitignore, .cursor/skills/tdd-script/evidence/\*\*, scripts/\*\*, docs/\*-doc-skill/confluence-doc.py - **Network endpoints:** https://confluence.huan.tv ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs dist/postinstall.js automatically., dist/postinstall.js calls setupProject on the consumer project with yes:true., dist/steps/setupProject.js writes skills into .cursor, .claude, .codex, and .openclaw., It adds always-apply Cursor rules and broad Claude Bash allow rules., It patches consumer package.json, copies scripts, and removes evidence directories., The installed Confluence template embeds default authentication material. - **Evidence against:** No install-time network request or downloaded payload was found., Network access is in later user-invoked probe/template functionality. ## Public findings ### 1.
