Install-time code offers to add Domma Claude guidance to the consumer project, defaulting to acceptance. No exfiltration, remote payload execution, or destructive behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-06T15:28:57.430Z - **Finished:** 2026-08-06T15:29:49.426Z - **Download time:** 510 ms - **Static scan time:** 1109 ms - **AI review time:** 50376 ms - **Total time:** 51996 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code offers to add Domma Claude guidance to the consumer project, defaulting to acceptance. No exfiltration, remote payload execution, or destructive behavior was found. - **Trigger:** npm postinstall; explicit domma setup-ai CLI command - **Impact:** May alter a project's Claude Code instruction surface with package-provided conventions. - **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:** 2026-08-06T15:29:49.426Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies first-party AI guidance and scaffolding files - **Rationale:** Source inspection confirms install-time mutation of a consumer AI-agent control surface, albeit interactive and package-aligned. Policy classifies this first-party agent extension setup as warn rather than block. - **Files touched:** bin/postinstall.js, bin/domma-cli.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json, project-root/CLAUDE.md, project-root/.claude/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **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 then copies CLAUDE.md and .claude/ into the consumer project., Prompt defaults to copy unless the user enters n/no., CLI setup-ai also writes those agent-guidance paths. - **Evidence against:** Copied .claude/settings.json contains framework conventions only; no hooks, commands, or remote skill channel., Postinstall makes no network request or credential/env harvest., Writes are limited to missing files and are package-aligned templates., CLI child process only installs live-server after an explicit serve prompt. ## Public findings ### 1.
