It installs skills and configures Codex child agents to use this package's relay without a separate setup command. - **Trigger:** Installing the package globally, and later running a mutating CLI command when an update is available. - **Impact:** It can redirect Codex child-agent traffic to the local relay and persist package-controlled skills across supported agent tools. - **Evidence paths:** package.json, scripts/install-skill.mjs, dist/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T21:22:47.786Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall AI-agent configuration injection with automatic global self-update. - **Attack narrative:** The package registers a postinstall hook that, on global installation, writes into Claude Code, Codex, and OpenCode configuration directories. It adds a Codex model provider backed by the package's loopback relay and creates child-agent definitions. Its update logic can globally install a newer release of itself, causing the same postinstall behavior again. This is an unconsented install-time mutation of multiple AI-agent control surfaces. - **Rationale:** The source establishes a concrete automatic lifecycle path that modifies foreign AI-agent settings and agent definitions, then persists it through automatic global self-updates. This meets the install-hook abuse blocking policy. - **Files touched:** .claude/skills/llm-relay/SKILL.md, .codex/skills/llm-relay/SKILL.md, .codex/config.toml, .codex/agents/default.toml, .codex/agents/relay\_coding.toml, opencode/skills/llm-relay/SKILL.md - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs an install script after installation., That script runs for global installs and writes skills into Claude Code, Codex, and OpenCode configuration locations., The postinstall script adds a Codex provider pointing to the package's local relay and creates two Codex child-agent definitions., The CLI can automatically reinstall the same package globally when it finds a newer version, re-triggering its postinstall hook. - **Evidence against:** The install script skips ordinary local installs unless forced., The package uses a loopback relay endpoint rather than an unrelated external host for the injected provider. ## Public findings ### 1.
