The postinstall script can write CLAUDE.md and .claude files into the consumer project during package installation. - **Trigger:** npm install lifecycle postinstall - **Impact:** Mutates Claude Code control/instruction files in the consuming project at install time. - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, templates/kickstart/.claude/snippets.md - **Review source:** ai\_review - **Reviewed:** 2026-07-01T10:07:05.500Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default-yes prompt copies package-supplied AI assistance files - **Attack narrative:** On install, package.json runs bin/postinstall.js. If installed under node\_modules outside CI, it locates the consumer project root and asks whether to copy AI assistance files; any response other than explicit n/no, including empty default input, proceeds. It then writes CLAUDE.md, .claude/, blueprints/, and types/ from package templates into the project, changing AI-agent instruction/control surface during installation. - **Rationale:** Even though the copied instructions look package-aligned, install-time default-yes mutation of CLAUDE.md/.claude is a concrete unconsented AI-agent control-surface write. No exfiltration was found, but this behavior meets the firewall block boundary for lifecycle AI-agent control hijack. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** CLAUDE.md, .claude/, blueprints/, types/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json defines postinstall: node bin/postinstall.js., bin/postinstall.js runs during npm install when cwd is under node\_modules and not CI., bin/postinstall.js prompts but treats empty/default answer as consent, then writes AI-agent files to project root., bin/postinstall.js copies templates/kickstart/CLAUDE.md and templates/kickstart/.claude/ plus blueprints/types., bin/domma-cli.js also exposes user-invoked setup-ai that copies the same AI assistance files. - **Evidence against:** No credential harvesting or exfiltration found in inspected lifecycle/CLI code., Network references are docs/CDN/local dev URLs or user-invoked live-server behavior., CLI file writes are mostly project scaffolding/templates and require explicit domma commands., CLAUDE.md content appears framework guidance, not obvious prompt injection for exfiltration/destruction. ## Public findings ### 1.
