Adds or replaces persistent agent instructions in home-directory control surfaces. - **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:** 0.1.14 - **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. Installation automatically modifies multiple foreign coding agents' skill directories without a consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-05T14:17:13.081Z - **Finished:** 2026-10-05T14:18:16.250Z - **Download time:** 761 ms - **Static scan time:** 1093 ms - **AI review time:** 61314 ms - **Total time:** 63169 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:** Installation automatically modifies multiple foreign coding agents' skill directories without a consent prompt. - **Trigger:** npm installation runs the postinstall hook when the bundled CLI exists. - **Impact:** Adds or replaces persistent agent instructions in home-directory control surfaces. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist-bin/x-agent-relay.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-05T14:18:16.250Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes skills install --all, bypassing selection and copying the packaged delegation skill into every detected agent target. - **Attack narrative:** The npm postinstall hook invokes the bundled skill installer with --all. The installer detects coding agents, bypasses its interactive selection, creates delegation skill directories, and copies its instructions into those agents' home directories. This automatically changes foreign agent control surfaces and can overwrite an existing delegation skill. - **Rationale:** Inspected source establishes unconsented postinstall mutation of multiple foreign AI-agent control surfaces. This meets the supplied blocking policy even though the skill serves package-related functionality. - **Files touched:** ~/.claude/skills/delegate/SKILL.md, ~/.codex/skills/delegate/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs scripts/postinstall.mjs after installation., The postinstall hook launches the bundled CLI with skills install --all., The CLI targets foreign agent skill directories, including Claude Code and Codex., The installer creates a delegate skill directory and copies SKILL.md there, overwriting an existing file., The --all option bypasses the selection prompt and installs into every detected target. - **Evidence against:** The installed skill supports the package's delegation functionality; no covert credential theft was established. ## Affected versions and remediation This report applies to x-agent-relay-cli@0.1.14. - Avoid installing x-agent-relay-cli@0.1.14. 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.
