Future agent sessions across supported tools can load package-provided instructions and 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:** 2.4.0 - **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. Source inspection confirms an automatic postinstall mutation of several foreign AI-agent configuration surfaces. This meets the blocking policy even though the installer avoids overwriting ordinary files and shows no network exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-27T13:48:50.977Z - **Finished:** 2026-08-27T13:50:59.998Z - **Download time:** 255 ms - **Static scan time:** 1466 ms - **AI review time:** 127299 ms - **Total time:** 129021 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 modifies multiple AI-agent instruction and agent directories. This is an unconsented broad AI-agent control-surface change. - **Trigger:** npm postinstall during package installation - **Impact:** Future agent sessions across supported tools can load package-provided instructions and agents. - **Evidence paths:** package.json, scripts/install-skill.sh, skills/cw-cli/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T13:50:59.998Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Creates package-controlled symlinks in global agent and skill directories. - **Attack narrative:** The package runs its installer automatically at npm postinstall. That installer places symlinks to package-controlled skills and agents into shared configuration locations for Agents, Claude, and Pi. Those locations affect future AI-agent behavior beyond the package's own command. The installed workflow instructions include mandatory routing and restrictions on alternative agent orchestration. This is a broad foreign AI-agent control-surface mutation without an explicit setup command. - **Rationale:** Source inspection confirms an automatic postinstall mutation of several foreign AI-agent configuration surfaces. This meets the blocking policy even though the installer avoids overwriting ordinary files and shows no network exfiltration. - **Files touched:** scripts/install-skill.sh, skills/cw-cli/SKILL.md, $HOME/.agents/skills, $HOME/.claude/skills, $HOME/.agents/agents, $HOME/.pi/agent/agents, $HOME/.claude/agents ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs a shell installer., The installer creates links in broad agent and skill directories for Agents, Claude, and Pi., It replaces eligible existing symlinks and installs package-controlled instruction files without user action., The installed skill directs agents to use this package's workflow and restricts alternative subagent use. - **Evidence against:** The installer skips ordinary existing files and symlinks that point elsewhere., No network calls or credential collection were found in the inspected lifecycle script. ## Affected versions and remediation This report applies to @zhushanwen/coding-workflow@2.4.0. - Avoid installing @zhushanwen/coding-workflow@2.4.0. 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.
