Persistent changes to agent instructions and possible replacement of existing delegation behavior; no credential theft is established. - **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:** 0.1.16 - **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 AI agents' global skill surfaces without consent. Existing delegate skills can be overwritten. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-05T14:16:19.453Z - **Finished:** 2026-10-05T14:17:31.357Z - **Download time:** 515 ms - **Static scan time:** 1060 ms - **AI review time:** 70328 ms - **Total time:** 71904 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 AI agents' global skill surfaces without consent. Existing delegate skills can be overwritten. - **Trigger:** npm postinstall when supported agent directories exist. - **Impact:** Persistent changes to agent instructions and possible replacement of existing delegation behavior; no credential theft is established. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist-bin/x-agent-relay.mjs, skills/delegate/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-05T14:17:31.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle hook runs skills install --all, bypassing the picker and copying the packaged skill into every detected agent's skill directory. - **Attack narrative:** Installing the package triggers a bundled installer with --all. It detects foreign coding agents and copies delegation instructions into their global skill directories, creating directories and overwriting existing skill files without asking. The interactive picker exists but is bypassed by the lifecycle caller. This establishes unconsented installation-time mutation of a broad AI-agent control surface. - **Rationale:** The inspected lifecycle chain performs unconsented writes to foreign agents' global instructions. This meets the explicit blocking rule for installation-time AI-agent control-surface mutation, regardless of the skill's package-aligned purpose. - **Files touched:** ~/.claude/skills/delegate/SKILL.md, ~/.codex/skills/delegate/SKILL.md, ~/.agents/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., scripts/postinstall.mjs invokes the bundled skill installer with --all., The installer targets foreign agents' global skill directories, including Codex, Claude Code, and shared ~/.agents., The --all option bypasses the interactive selection; every detected target receives the skill., The installer creates delegate/SKILL.md and copies over any existing file without confirmation., The copied skill instructs agents to delegate tasks to remote agents. - **Evidence against:** The skill describes user-requested delegation; inspected installation code does not establish credential theft., Targets require existing agent directories, but this detection does not provide consent. ## Affected versions and remediation This report applies to x-agent-relay-cli@0.1.16. - Avoid installing x-agent-relay-cli@0.1.16. 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.
