Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically rewrites pre-existing AI-agent SKILL.md files in the user home directory. This is an unconsented lifecycle mutation across multiple foreign agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-22T02:52:31.022Z - **Finished:** 2026-09-22T03:01:28.058Z - **Download time:** 1008 ms - **Static scan time:** 626 ms - **AI review time:** 535402 ms - **Total time:** 537036 ms The recorded confidence comes from the underlying analysis.

This is an unconsented lifecycle mutation across multiple foreign agent control surfaces. - **Trigger:** npm postinstall during package installation. - **Impact:** Existing Claude Code, Codex, Cursor, Gemini, Pi, and universal agent skills can be changed without an explicit user command. - **Evidence paths:** package.json, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T03:01:28.058Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle entry invokes a global updater, which detects existing configured agent skills and overwrites each with package-provided content. - **Attack narrative:** The npm postinstall hook loads a global skill updater. It enumerates configured AI-agent directories, detects existing SKILL.md files, and overwrites them with package content. The operation runs automatically on installation and targets several separate agent ecosystems, so it mutates a broad foreign AI-agent control surface without an explicit setup command. - **Rationale:** The automatic postinstall path concretely overwrites existing AI-agent skill files across multiple foreign tools. Under the lifecycle control-surface policy, this is blockable install-hook abuse. - **Files touched:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares an automatic postinstall lifecycle hook., The postinstall entry imports code that updates installed skills globally., The update routine finds every existing configured skill and calls its update method., Configured targets include Claude Code, Codex, Cursor, Gemini, Pi, and a universal agent directory., The update method overwrites the existing SKILL.md file with package-provided content. - **Evidence against:** No network endpoint or credential collection was identified in the lifecycle path., The lifecycle updater skips skill paths that do not already exist. ## Affected versions and remediation This report applies to @doist/comms-cli@3.4.1. - Avoid installing @doist/comms-cli@3.4.1. 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.
