Package installation can alter instructions used by multiple AI coding agents. - **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:** 3.2.0 - **Selected version is latest:** No - **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. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically updates agent skill files in several unrelated home-directory agent control surfaces. The update is silent on failure and occurs without an explicit CLI command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T15:32:24.089Z - **Finished:** 2026-09-15T15:33:17.335Z - **Download time:** 1013 ms - **Static scan time:** 649 ms - **AI review time:** 51584 ms - **Total time:** 53246 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:** Installing the package automatically updates agent skill files in several unrelated home-directory agent control surfaces. The update is silent on failure and occurs without an explicit CLI command. - **Trigger:** npm installation runs postinstall. - **Impact:** Package installation can alter instructions used by multiple AI coding agents. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T15:33:17.335Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic rewrite of installed third-party agent skills. - **Attack narrative:** On npm installation, package.json starts scripts/postinstall.js, which imports the compiled postinstall module. That module silently calls the all-agent updater with home-directory scope. The updater detects installed skills and rewrites them. Its registry includes multiple foreign agent directories and a shared .agents directory, so installing this CLI changes AI-agent control-surface files without an explicit user command. - **Rationale:** The package has a concrete automatic postinstall chain that mutates foreign and broad AI-agent control surfaces. This meets the install-hook abuse blocking policy despite no observed network exfiltration. - **Files touched:** scripts/postinstall.js, dist/postinstall.js, $HOME/.claude/skills/comms-cli/SKILL.md, $HOME/.codex/skills/comms-cli/SKILL.md, $HOME/.cursor/skills/comms-cli/SKILL.md, $HOME/.gemini/skills/comms-cli/SKILL.md, $HOME/.pi/skills/comms-cli/SKILL.md, $HOME/.agents/skills/comms-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically loads the lifecycle updater., The updater rewrites every already installed agent skill without user action., The registry targets Claude Code, Codex, Cursor, Gemini, Pi, and the shared .agents directory., The installer writes skill content into home-directory agent control surfaces. - **Evidence against:** No lifecycle network request or credential exfiltration was found., The manifest has no runtime dependency on this package itself. ## Affected versions and remediation This report applies to @doist/comms-cli@3.2.0. - Avoid installing @doist/comms-cli@3.2.0. 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.
