Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Installs package-supplied Claude command instructions into ~/.claude/commands, changing future Claude Code behavior when /mmt is invoked. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection confirms unconsented npm postinstall mutation of a broad foreign AI-agent control surface, which meets the firewall block policy even without credential theft or exfiltration. The behavior is documented and package-aligned, but it occurs automatically at install time rather than via an explicit setup command. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-07-05T21:28:15.207Z - **Finished:** 2026-07-05T21:29:13.394Z - **Download time:** 509 ms - **Static scan time:** 67 ms - **AI review time:** 57610 ms - **Total time:** 58187 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:** The package mutates Claude Code's user command surface during npm postinstall. This creates or updates a slash command under the user's home directory without an explicit user command. - **Trigger:** npm install or npm install -g of @mamadoudicko/mmt@0.1.1 - **Impact:** Installs package-supplied Claude command instructions into ~/.claude/commands, changing future Claude Code behavior when /mmt is invoked. - **Evidence paths:** package.json, scripts/postinstall.js, .claude/commands/mmt.md, bin/mmt, lib/compose.js, lib/runner.js, lib/store.js, lib/skills.js, scripts/gen-catalog.js - **Review source:** ai\_review - **Reviewed:** 2026-07-05T21:29:13.394Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall write to AI-agent control files - **Attack narrative:** On installation, npm runs scripts/postinstall.js. That script copies the package's .claude/commands/mmt.md into ~/.claude/commands/mmt.md and seeds package skills/teams under ~/.my-mini-team. The installed slash command is then part of Claude Code's command surface and instructs future /mmt sessions to orchestrate subagents and write reports. - **Rationale:** Static inspection confirms unconsented npm postinstall mutation of a broad foreign AI-agent control surface, which meets the firewall block policy even without credential theft or exfiltration. The behavior is documented and package-aligned, but it occurs automatically at install time rather than via an explicit setup command. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** package.json, scripts/postinstall.js, .claude/commands/mmt.md, ~/.claude/commands/mmt.md, ~/.my-mini-team/skills/\*/SKILL.md, ~/.my-mini-team/teams/\*.team.yaml - **Network endpoints:** https://github.com/mamadoudicko/my-mini-team/tree/main/catalog/, https://github.com/mamadoudicko/my-mini-team, https://mamadoudicko.github.io/my-mini-team/, https://github.com/mamadoudicko/my-mini-team/issues ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json defines postinstall: node scripts/postinstall.js, scripts/postinstall.js writes ~/.claude/commands/mmt.md during install, scripts/postinstall.js seeds ~/.my-mini-team/skills and ~/.my-mini-team/teams at install time, .claude/commands/mmt.md is an AI-agent slash command that instructs Claude to run subagents and write run reports - **Evidence against:** scripts/postinstall.js has MMT\_NO\_POSTINSTALL opt-out and catches errors, No credential harvesting or network exfiltration found in inspected source, Network URLs are repository/homepage/catalog links, not runtime exfil endpoints, CLI child\_process usage is user-invoked for editor/claude workflows ## Affected versions and remediation This report applies to @mamadoudicko/mmt@0.1.1. - Avoid installing @mamadoudicko/mmt@0.1.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
