Later mutating CLI commands can fetch the latest release and reinstall the package globally. - **Trigger:** npm install -g llm-relay, or a mutating llm-relay CLI command after an update is available. - **Impact:** Changes Codex provider routing and child-agent definitions plus host skill files without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.mjs, dist/self-update.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T05:41:35.279Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall AI-agent configuration mutation with automatic self-reinstallation. - **Attack narrative:** The package's postinstall hook runs on global installation and writes a provider block and two child-agent definitions into the user's shared Codex configuration while copying skills into several AI-agent hosts. Its CLI also checks the npm registry during mutating commands and can reinstall the same package globally, causing lifecycle behavior from a newer release to run again. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Rationale:** The global-install guard does not make automatic modification of shared Codex routing and agent files user-invoked setup. The update path compounds the risk by automatically reinstalling the package from the registry. - **Files touched:** ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.codex/agents/relay\_coding.toml, ~/.claude/skills/llm-relay/SKILL.md, ~/.codex/skills/llm-relay/SKILL.md, $XDG\_CONFIG\_HOME/opencode/skills/llm-relay/SKILL.md - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically runs the global skill installer., On global installation, the installer adds a llm-relay provider and child-agent files to the user's shared Codex configuration., The postinstall also copies package skills into Claude Code, Codex, and OpenCode user configuration directories., Mutating CLI commands check the npm registry and can reinstall llm-relay globally, rerunning lifecycle code. - **Evidence against:** The installer exits for ordinary non-global installs unless forced., No source inspected showed collection or exfiltration of credentials to an attacker-controlled endpoint., The Claude hook mutation is gated behind an explicit offload command. ## Public findings ### 1.
