Install-time lifecycle code can place package-supplied Claude Code guidance/config into the consumer project root. This mutates an AI-agent control surface during dependency installation, with default-yes behavior after the prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-01T00:32:35.939Z - **Finished:** 2026-07-01T00:33:55.024Z - **Download time:** 505 ms - **Static scan time:** 613 ms - **AI review time:** 77965 ms - **Total time:** 79085 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time lifecycle code can place package-supplied Claude Code guidance/config into the consumer project root. This mutates an AI-agent control surface during dependency installation, with default-yes behavior after the prompt. - **Trigger:** npm install of domma-js in node\_modules - **Impact:** Can influence future Claude Code behavior in the consuming project via package-supplied CLAUDE.md and .claude/settings.json - **Evidence paths:** package.json, bin/postinstall.js, bin/domma-cli.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-07-01T00:33:55.024Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies AI-agent instruction/config files - **Attack narrative:** On installation, package.json invokes bin/postinstall.js. When running from node\_modules outside CI, it finds the consuming project root and prompts to copy AI assistance files; any answer other than n/no proceeds. The copied files include CLAUDE.md and .claude/settings.json, which are Claude Code control/context files supplied by the package. - **Rationale:** This is concrete install-time AI-agent control-surface mutation, not merely documentation in the package tarball. The prompt reduces stealth but default-yes lifecycle writes into the consumer project root remain unconsented enough for firewall blocking under the stated policy. 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 at install in node\_modules and locates the parent project root, bin/postinstall.js defaults to copying unless answer is n/no, then writes CLAUDE.md and .claude/ plus blueprints/types, templates/kickstart/.claude/settings.json is an AI-agent control/config file, bin/domma-cli.js setup-ai can also copy CLAUDE.md and .claude/ into cwd - **Evidence against:** postinstall has CI and development-context guards, postinstall prompts before copying in interactive installs, No credential harvesting or exfiltration endpoints found in inspected install script, CLI file writes are otherwise project scaffolding/template operations ## Public findings ### 1.
