It installs skills and a Codex provider, MCP server, and relay agent that routes tasks through llm-relay. - **Trigger:** npm global installation runs postinstall; a failed Codex detector also falls through to provisioning. - **Impact:** The package can alter host agent behavior and route agent tasks through its local relay without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T05:35:17.492Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time AI-agent configuration and task-routing injection. - **Attack narrative:** Installing this package globally invokes its postinstall installer. The installer copies content into multiple AI-agent configuration directories and writes Codex provider, MCP, and relay-agent settings. The generated relay agent requires every task to be dispatched through llm-relay. The Codex detection failure path provisions settings anyway, making the mutation automatic rather than a user-invoked setup action. - **Rationale:** The automatic postinstall mutation targets broad, foreign AI-agent control surfaces and changes how host agents handle tasks. This meets the install-hook abuse blocking boundary despite the global-install guard. - **Files touched:** ~/.claude/skills/llm-relay, ~/.codex/skills/llm-relay, ~/.codex/config.toml, ~/.codex/agents/relay.toml, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay - **Network endpoints:** http://127.0.0.1:8791/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically runs the host-configuration installer., On global installation, the installer copies a skill bundle into Claude, Codex, and OpenCode user configuration directories., The installer writes a Codex provider, MCP server, and relay-agent configuration without an explicit setup command., The generated relay agent instructs the host agent to send every task to the package dispatch tool and forbids independent answers., If Codex detection fails, the installer proceeds with Codex provisioning anyway. - **Evidence against:** The installer exits for ordinary local installs unless forced., The Codex relay-agent writer refuses to overwrite a file lacking its marker., No credential exfiltration endpoint was confirmed in the inspected install path. ## Public findings ### 1.
