Install-time script can add Claude Code instruction/configuration files to the consuming project after a default-yes prompt. This changes an AI-agent control surface but has no observed exfiltration or payload execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-05T22:10:02.883Z - **Finished:** 2026-08-05T22:10:55.470Z - **Download time:** 255 ms - **Static scan time:** 648 ms - **AI review time:** 51682 ms - **Total time:** 52587 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time script can add Claude Code instruction/configuration files to the consuming project after a default-yes prompt. This changes an AI-agent control surface but has no observed exfiltration or payload execution. - **Trigger:** npm install followed by accepting or submitting the postinstall prompt - **Impact:** Influences future Claude Code sessions in that project - **Evidence paths:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T22:10:55.470Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** prompted copy of Claude guidance into project root - **Rationale:** This is a guarded install-time AI-agent configuration mutation, not concrete malicious behavior. Default-yes prompting still creates a meaningful lifecycle risk. - **Files touched:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, templates/kickstart/.claude/memory/MEMORY.md, templates/kickstart/.claude/snippets.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js on install., bin/postinstall.js prompts with default Y, then writes project CLAUDE.md and .claude/., Templates contain Claude Code guidance and project settings. - **Evidence against:** Writes occur only after an interactive prompt and skip existing targets., No credential harvesting, exfiltration, remote payload, or shell execution in postinstall., Template guidance is framework-specific; no instruction to bypass controls or leak data. ## Public findings ### 1.
