A global npm install automatically alters multiple AI-agent control surfaces and installs a directive-bearing skill.

Later mutating CLI use can retrieve and install a newer global release. - **Trigger:** Install the package globally, then invoke a mutating llm-relay CLI command. - **Impact:** Agent hosts can load package-controlled instructions, a local provider, and an MCP command without a separate setup action. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T22:09:20.103Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall agent configuration mutation and automatic global self-update. - **Attack narrative:** The package's postinstall hook runs automatically. For global installs it writes skills into several agent-host directories and appends a Codex provider plus MCP server command. The shipped skill tells agents to use the relay for delegatable work without the operator asking, changing agent behavior through those installed control surfaces. Separately, mutating CLI commands check the npm registry and can install and restart a newer global package release. - **Rationale:** This is unconsented postinstall mutation of foreign AI-agent control surfaces, coupled with installed behavior directives and automatic global updating. The global-only gate does not remove the automatic lifecycle trigger for users who install the CLI globally. - **Files touched:** ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/skills/llm-relay/SKILL.md, ~/.codex/config.toml, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay/SKILL.md - **Network endpoints:** https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook launches the host-skill installer., On global installation, the installer copies a skill into Claude, Codex, and OpenCode user configuration directories., The installer appends a provider and MCP server command to the user's Codex configuration., The installed skill instructs agents to offload work without the operator asking., Mutating CLI commands check the npm registry and can globally install and restart a newer release. - **Evidence against:** The postinstall script exits for ordinary local installs unless forced., No direct credential theft or external secret exfiltration was found in the inspected paths. ## Public findings ### 1.
