It writes managed agent configuration and copies skills into multiple agent control surfaces. - **Trigger:** npm install of the package as a top-level project dependency - **Impact:** Unconsented mutation of broad project AI-agent instruction and skill surfaces. - **Evidence paths:** package.json, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/templates.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-13T21:30:59.410Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall invokes non-interactive bootstrap that writes project AI-agent configuration - **Attack narrative:** During npm install, postinstall selects the project target and invokes bootstrap with --non-interactive and --yes. Bootstrap writes generated project configuration, managed instruction files, and agent skills; the generated synchronization script copies skills into both .agents and .claude. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The package performs a concrete, automatic postinstall write chain into the consuming project's AI-agent configuration rather than requiring an explicit user command. This meets the blocking policy for unconsented install-time mutation of a foreign/broad AI-agent control surface. - **Files touched:** AGENTS.md, CLAUDE.md, GEMINI.md, CONVENTIONS.md, .gitignore, .ai/, .agents/skills/, .claude/skills/, .ai-agent-kit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., Postinstall imports a governed kit into the install project., Bootstrap writes generated configuration and managed root files., Generated script propagates skills into .agents and .claude. - **Evidence against:** No credential harvesting or exfiltration found in inspected install path., Pricing network requests are explicit runtime functionality, not used by postinstall. ## Public findings ### 1.
