The injected instructions steer future agent sessions to use the Kordis registry. - **Trigger:** npm postinstall during package installation - **Impact:** Future Claude Code, Codex, and Gemini sessions can be influenced to run this package's registry commands and retrieve registry content. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js, assets/KORDIS.md - **Review source:** ai\_review - **Reviewed:** 2026-09-13T23:52:23.511Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent lifecycle-driven global AI-agent instruction injection - **Attack narrative:** On installation, npm runs postinstall, which silently invokes setup. Setup detects existing global AI-agent directories, then creates or rewrites their instruction files and installs bundled skills. The injected guide tells future agents to consult Kordis for unfamiliar tasks and to run registry commands. This is an unconsented, install-time modification of broad foreign AI-agent control surfaces. - **Rationale:** The complete lifecycle path automatically and silently modifies global instruction files for three unrelated AI-agent tools, then injects directives that influence future sessions. This is concrete install-hook abuse rather than an explicit user-invoked setup action. - **Files touched:** ~/.claude/CLAUDE.md, ~/.codex/AGENTS.md, ~/.gemini/GEMINI.md, ~/.claude/skills/\*/SKILL.md, ~/.codex/skills/\*/SKILL.md, ~/.gemini/skills/\*/SKILL.md - **Network endpoints:** https://api.kordis.store ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package defines an automatic postinstall hook., The postinstall hook silently runs the package setup command., Setup targets global Claude Code, Codex, and Gemini instruction files., Setup creates or rewrites global agent instructions and bundled skills., The injected guide directs agents to use the package registry for broad future tasks. ## Affected versions and remediation This report applies to @rayul/kordis@0.14.0. - Avoid installing @rayul/kordis@0.14.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
