Installing the package automatically modifies broad, foreign AI-agent control surfaces and can trigger a project upgrade. This occurs without an explicit package command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-22T14:38:27.523Z - **Finished:** 2026-07-22T14:39:03.403Z - **Download time:** 509 ms - **Static scan time:** 3290 ms - **AI review time:** 32080 ms - **Total time:** 35880 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies broad, foreign AI-agent control surfaces and can trigger a project upgrade. This occurs without an explicit package command. - **Trigger:** npm postinstall - **Impact:** Injected skills and agent prompts can influence multiple installed AI coding tools; the upgrade can modify a detected project. - **Evidence paths:** package.json, scripts/install-skills.mjs, agents/karpathy-reviewer.md - **Review source:** ai\_review - **Reviewed:** 2026-07-22T14:39:03.403Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** cross-platform AI-agent skill/agent/config installation plus automatic CLI upgrade - **Attack narrative:** On npm installation, the postinstall script automatically installs package-controlled skills across multiple AI-agent home directories, writes agent prompts to Claude's agent loader, and creates user/project configuration. It also detects prior project state and spawns an automatic upgrade. These are unconsented install-time mutations of broad foreign AI-agent control surfaces. - **Rationale:** The postinstall behavior directly meets the blocking policy for unconsented mutation of foreign/broad AI-agent control surfaces. Opt-out flags do not make the default installation consensual. - **Files touched:** scripts/install-skills.mjs, skills/\*\*, agents/karpathy-reviewer.md, output-styles/\*\*, ~/.claude/skills, ~/.codex/skills, ~/.cursor/skills, ~/.trae/skills, ~/.claude/agents, ~/.peaks/config.json, \/.peaks/config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., scripts/install-skills.mjs silently fans out bundled skills to ~/.claude, ~/.codex, ~/.cursor, ~/.trae and other agent directories., The same postinstall copies agent prompts into ~/.claude/agents and writes output styles/config under user-controlled agent roots., Postinstall detects a project and invokes \`peaks upgrade --auto\` via spawnSync. - **Evidence against:** Installer has opt-out environment variables and preserves unmanaged conflicting files., No install-time network request or credential exfiltration was found. ## Public findings ### 1.
