Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The lifecycle downloads are explicit, hash-pinned companion binaries for documented browser and shell functionality. Source inspection found no credential harvesting, covert external endpoint, or install-time mutation of a foreign AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-09T21:56:51.031Z - **Finished:** 2026-08-09T21:57:41.015Z - **Download time:** 512 ms - **Static scan time:** 9978 ms - **AI review time:** 39493 ms - **Total time:** 49984 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Postinstall fetches two version-pinned, checksum-verified companion binaries into ~/.negotium. Agent, shell, browser, and credential functions are runtime features of the advertised multi-agent CLI; no unconsented exfiltration or foreign control-surface mutation was found. - **Trigger:** npm postinstall; subsequent explicit negotium CLI/runtime use - **Impact:** No confirmed malicious attack chain - **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/runtime/src/mcp/vault-http.ts, dist/runtime/src/mcp/session-comm/peer-forward.ts, dist/runtime/src/agents/codex-provider.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-09T21:57:41.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified companion-binary installation and user-invoked local agent runtime - **Rationale:** The lifecycle downloads are explicit, hash-pinned companion binaries for documented browser and shell functionality. Source inspection found no credential harvesting, covert external endpoint, or install-time mutation of a foreign AI-agent control surface. - **Files touched:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/v0.1.19/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.5/bash-rs - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.19, https://github.com/maestrojeong/bash-rs-mcp/releases/download/v0.1.5 ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs postinstall downloaders, install-browser-rs.mjs fetches a native binary, install-bash-rs.mjs fetches a native binary - **Evidence against:** Both installers pin SHA-256 and verify before install, Downloads only write package-owned ~/.negotium binaries, No lifecycle AI-agent config mutation found, Runtime agent integrations are activated by CLI/runtime use, Peer forwarding is restricted to authenticated loopback URLs, Vault HTTP requires HTTPS and explicit credential placeholders ## Affected versions and remediation This report applies to negotium@0.2.19. - Review the evidence and your use of negotium@0.2.19 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
