Installing the package executes a postinstall hook that installs package-controlled skills, agents, and output styles into broad third-party AI-agent control surfaces. It also sets Claude Code's active output style and can launch an automatic project upgrade. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T21:29:32.458Z - **Finished:** 2026-08-05T21:30:17.328Z - **Download time:** 506 ms - **Static scan time:** 5625 ms - **AI review time:** 38738 ms - **Total time:** 44870 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package executes a postinstall hook that installs package-controlled skills, agents, and output styles into broad third-party AI-agent control surfaces. It also sets Claude Code's active output style and can launch an automatic project upgrade. - **Trigger:** npm postinstall - **Impact:** Subsequent AI-agent sessions can load package-supplied instructions across multiple user-level tool configurations. - **Evidence paths:** package.json, scripts/install-skills.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:30:17.328Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-platform AI-agent configuration and prompt installation - **Attack narrative:** On npm installation, package.json invokes scripts/install-skills.mjs. Its main path deliberately iterates all configured AI platforms and links bundled skills into user-home agent skill directories, copies bundled agents and output styles, and changes ~/.claude/settings.json to select the package output style. These mutations occur without an explicit user CLI command and extend beyond a package-owned configuration surface, creating persistent control over future agent behavior. - **Rationale:** Direct source inspection confirms unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the install-control-surface blocking policy regardless of the absence of exfiltration. - **Files touched:** ~/.claude/skills/\*, ~/.trae/skills/\*, ~/.trae-cn/skills/\*, ~/.codex/skills/\*, ~/.cursor/skills/\*, ~/.qoder/skills/\*, ~/.tongyi-lingma/skills/\*, ~/.hermes/skills/\*, ~/.openclaw/skills/\*, ~/.zcode/skills/\*, ~/.claude/agents/\*.md, ~/.claude/output-styles/\*.md, ~/.claude/settings.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., install-skills.mjs fans out at install time to 10 AI-tool home directories., It symlinks bundled skills into ~/.claude, ~/.codex, ~/.cursor, ~/.trae and other platform skill folders., It copies agent prompts into ~/.claude/agents and output styles into ~/.claude/output-styles., It mutates ~/.claude/settings.json to activate peaks-skill-swarm without an explicit command., It can auto-run peaks upgrade against a detected project during postinstall. - **Evidence against:** No package-controlled network request or credential exfiltration was found in the inspected install hook., The hook includes path and ownership checks and preserves unmanaged target files. ## Public findings ### 1.
