It creates and overwrites packaged skill files under the user's Claude configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-12T16:38:41.327Z - **Finished:** 2026-08-12T16:39:36.202Z - **Download time:** 760 ms - **Static scan time:** 2352 ms - **AI review time:** 51761 ms - **Total time:** 54875 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates Claude Code's global skill control surface without an explicit user command. It creates and overwrites packaged skill files under the user's Claude configuration. - **Trigger:** npm install (including non-interactive dependency installation) - **Impact:** Package-supplied behavioral instructions become active in the user's AI-agent environment. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/skills-install.ts, dist/cli/skills-install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T16:39:36.202Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-launched overwrite of Claude Code skills - **Attack narrative:** Installation invokes a postinstall script that launches the bundled skills installer. That installer defaults to ~/.claude/skills, creates the directory, and copies package Markdown files there with overwrite semantics. This changes a foreign, broad AI-agent instruction surface without requiring the user to run an explicit setup command. - **Rationale:** The package performs unconsented install-time mutation of Claude Code's global skills directory. This meets the firewall block policy for foreign/broad AI-agent control-surface mutation. - **Files touched:** scripts/postinstall.mjs, dist/cli/skills-install.js, skills/\*.md, ~/.claude/skills/\*.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs a postinstall hook on every installation., The hook directly launches the skill installer when its bundled file exists., The installer creates and overwrites Markdown files in Claude Code's global skills directory. - **Evidence against:** The hook has an environment-variable opt-out., No postinstall network request, credential harvesting, or shell payload execution was found in the inspected hook path. ## Public findings ### 1.
