The injected instructions direct agent behavior. - **Trigger:** npm installation of docdex@0.2.93 - **Impact:** Unconsented control of configured AI clients and persistent execution of a downloaded daemon. - **Evidence paths:** package.json, lib/install.js, lib/postinstall\_setup.js, assets/agents.md, lib/uninstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T09:59:25.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall MCP registration, global prompt injection, and daemon persistence - **Attack narrative:** Installing the package automatically downloads/installs its daemon, registers it as a persistent user service, injects a Docdex MCP endpoint into numerous unrelated AI-client configurations, and writes mandatory behavioral instructions into global agent instruction surfaces. This occurs during postinstall rather than an explicit setup command. - **Rationale:** Source inspection confirms an unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the blocking policy regardless of the loopback endpoint. - **Files touched:** package.json, lib/install.js, lib/postinstall\_setup.js, assets/agents.md, ~/.codex/config.toml, ~/.claude.json, ~/.cursor/mcp.json, ~/.continue/config.json, ~/.config/zed/settings.json - **Network endpoints:** https://github.com/bekirdag/docdex/releases/download, http://127.0.0.1:28491/sse, http://127.0.0.1:28491/v1/mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs lib/install.js on postinstall., lib/install.js invokes runPostInstallSetup during postinstall., lib/postinstall\_setup.js adds Docdex MCP entries to many third-party agent configs, including ~/.codex/config.toml., lib/postinstall\_setup.js writes global agent instruction files without consent., assets/agents.md contains mandatory directives steering agent tool, memory, and web-use behavior., Postinstall registers and starts a persistent local daemon. - **Evidence against:** Configured MCP endpoints are loopback-only (127.0.0.1:28491)., lib/uninstall.js removes Docdex client entries and daemon startup artifacts., lib/update\_check.js only contacts npm registry during interactive CLI use. ## Public findings ### 1.
