Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-18T02:19:42.793Z - **Finished:** 2026-08-18T02:20:38.950Z - **Download time:** 504 ms - **Static scan time:** 5611 ms - **AI review time:** 50040 ms - **Total time:** 56157 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:** An explicit plugin-management command can register a gmax MCP server and insert package-provided instructions into user-wide Codex configuration. Installation itself does not activate this behavior. - **Trigger:** User runs \`gmax plugin add/update codex\`, or confirms plugin installation during \`gmax setup\`. - **Impact:** Adds the package CLI as a Codex MCP tool and changes \`~/.codex/AGENTS.md\`; no automatic install-time mutation was confirmed. - **Evidence paths:** package.json, scripts/postinstall.js, dist/commands/codex.js, dist/commands/plugin.js, dist/commands/setup.js, dist/lib/index/grammar-loader.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T02:20:38.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit Codex MCP registration and AGENTS.md skill-block write - **Rationale:** Not malicious: the install hook only logs a message and agent configuration writes require an explicit plugin action or setup confirmation. Warn because that action registers an executable MCP tool and changes user-wide Codex instructions. - **Files touched:** ~/.codex/AGENTS.md, ~/.gmax/grammars/ - **Network endpoints:** https://huggingface.co/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Explicit \`gmax plugin add/update\` can register \`gmax mcp\` with Codex and modify the user-wide \`~/.codex/AGENTS.md\`., The interactive \`gmax setup\` command prompts before installing detected AI-client plugins., Runtime setup downloads declared ML models and grammars from package-aligned sources. - **Evidence against:** The npm postinstall hook only prints instructions and does not modify configuration., Codex registration completes before AGENTS.md is written, avoiding a partial config write on registration failure., No credential harvesting, arbitrary remote payload execution, or non-local data exfiltration was found in the inspected paths. ## Affected versions and remediation This report applies to grepmax@0.26.16. - Review the evidence and your use of grepmax@0.26.16 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.
