An explicitly opted-in postinstall path registers Context7 globally and installs SKS Codex skills. Default npm installation exits before those external mutations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-23T11:09:49.191Z - **Finished:** 2026-08-23T11:11:38.789Z - **Download time:** 1021 ms - **Static scan time:** 10441 ms - **AI review time:** 98135 ms - **Total time:** 109598 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicitly opted-in postinstall path registers Context7 globally and installs SKS Codex skills. Default npm installation exits before those external mutations. - **Trigger:** Install with SKS\_POSTINSTALL\_BOOTSTRAP=1. - **Impact:** Modifies the user's global AI-agent extension surface after explicit lifecycle opt-in. - **Evidence paths:** package.json, dist/cli/install-helpers.js, dist/cli/install-helpers-install-support.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T11:11:38.789Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global Codex MCP and skill installation - **Rationale:** No concrete malicious chain was found: external AI-agent mutations are gated by an explicit opt-in. The opt-in postinstall still changes global Codex extensions, so it warrants a warning under the lifecycle policy. - **Files touched:** dist/.sks-build-stamp.json, .codex/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall executes the SKS CLI., With explicit SKS\_POSTINSTALL\_BOOTSTRAP=1, postinstall adds a global Context7 MCP command., The same opt-in path installs global Codex skills and can remove stale generated skill shadows., Postinstall always restores a build stamp only inside its package root. - **Evidence against:** Default install returns before project, HOME, Codex, or global-SKS mutation., External mutation requires explicit environment-variable opt-in., No source evidence of credential harvesting, hidden exfiltration, or remote payload execution. ## Public findings ### 1.
