It installs an autonomous offload skill and configures Codex child agents to use the package's relay. - **Trigger:** Global installation, and later automatic global update during a mutating CLI command. - **Impact:** It can alter Claude Code, Codex, and OpenCode behavior without an explicit setup command, steering delegated work through the relay. - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T19:18:20.377Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes cross-host AI-agent configuration and self-update reinstalls the package. - **Attack narrative:** Installing this package globally invokes postinstall without a separate setup command. The installer copies a skill into several AI-agent hosts, adds a Codex provider, and creates a default child-agent configuration that uses the relay. The installed skill instructs hosts to offload work without operator approval. On later mutating CLI use, the package can automatically install a newer global release, which runs the lifecycle hook again. - **Rationale:** This is unconsented postinstall mutation of broad, foreign AI-agent control surfaces, combined with instructions that autonomously redirect agent work and a self-update path that repeats the lifecycle. The global-install gate and loopback endpoint do not remove that control-surface risk. - **Files touched:** package.json, scripts/install-skill.mjs, skills/llm-relay/SKILL.md, dist/self-update.js, ~/.codex/config.toml, ~/.codex/agents/default.toml, ~/.codex/agents/relay\_coding.toml, ~/.claude/skills/llm-relay/SKILL.md, ~/.config/opencode/skills/llm-relay/SKILL.md - **Network endpoints:** http://127.0.0.1:8791/v1, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs an installer automatically through npm postinstall., That installer adds a custom provider and creates a default Codex child-agent profile., It copies a skill into Claude Code, Codex, and OpenCode configuration directories during global installation., The shipped skill tells AI hosts to offload work without the operator asking., The CLI checks the npm registry and automatically reinstalls its global package version, repeating lifecycle behavior. - **Evidence against:** The lifecycle installer exits for ordinary local installs unless forced., The configured relay endpoint is loopback-only., No secret collection or external secret exfiltration was found in the inspected lifecycle code. ## Public findings ### 1.
