It writes managed instructions and adapter assets across broad, foreign agent control surfaces. - **Trigger:** npm project install of the package - **Impact:** Changes AGENTS.md and agent-specific configuration/skill directories without an explicit setup command or approval. - **Evidence paths:** package.json, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/adapters.mjs, dist/src/paths.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-15T13:49:49.236Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven non-interactive AI-agent configuration injection - **Attack narrative:** Installing the package triggers postinstall, which runs bootstrap with --non-interactive and --yes against the consuming project. Bootstrap defaults to all adapters and writes managed root instruction files plus agent configuration and skills under multiple agent-owned paths. This is unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The lifecycle hook performs a concrete, automatic project mutation across foreign AI-agent control surfaces. This meets the block boundary despite the absence of credential theft or install-time networking. - **Files touched:** AGENTS.md, CLAUDE.md, GEMINI.md, CONVENTIONS.md, .ai/, .agents/, .claude/, .codex/, .cursor/, .mcp.json, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install lifecycle is declared., postinstall automatically invokes non-interactive bootstrap in the installing project., Bootstrap writes managed root instructions and AI-agent configuration without user approval., Adapter selection defaults to every supported agent surface. - **Evidence against:** No install-time network or credential-exfiltration path was found., Pricing network requests are runtime CLI functionality, not part of postinstall. ## Public findings ### 1.
