Install-time code can mutate the consuming project's Claude Code control surface after an interactive Y/n prompt whose default accepts copying. It creates only absent files/directories from bundled framework guidance. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-05T10:52:41.947Z - **Finished:** 2026-08-05T10:53:36.438Z - **Download time:** 510 ms - **Static scan time:** 649 ms - **AI review time:** 53330 ms - **Total time:** 54491 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code can mutate the consuming project's Claude Code control surface after an interactive Y/n prompt whose default accepts copying. It creates only absent files/directories from bundled framework guidance. - **Trigger:** npm postinstall; user accepts the AI-assistance prompt or presses Enter - **Impact:** Changes future Claude Code project context; no exfiltration or payload execution confirmed. - **Evidence paths:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T10:53:36.438Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** prompted copy of bundled Claude Code guidance into project root - **Rationale:** This is a real guarded install-time AI-agent context mutation, so it warrants a warning. The interactive gate and benign inspected template contents do not establish malicious behavior. - **Files touched:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **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 during install, defaulting to copy on Enter., Postinstall writes CLAUDE.md and .claude/ into the consuming project., Templates provide Claude Code guidance and settings. - **Evidence against:** Copying is gated by an interactive prompt and skips CI., Existing target files/directories are not overwritten., Inspected agent templates contain framework conventions, not execution or exfiltration instructions., No install-time network, credential harvesting, or remote-code path found. ## Public findings ### 1.
