This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-09-04T02:16:38.607Z - **Finished:** 2026-09-04T02:18:08.261Z - **Download time:** 504 ms - **Static scan time:** 8575 ms - **AI review time:** 80574 ms - **Total time:** 89654 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation writes KORAINIT.md into the consumer project root. If a user activates it or runs the package’s setup commands, the package can install Claude hooks and managed content in agent instruction files. - **Trigger:** npm installation, followed by activation of KORAINIT.md or explicit koragraph hooks/practice commands. - **Impact:** A coding agent may receive package-authored instructions or execute package hook scripts in a consumer repository. - **Evidence paths:** package.json, scripts/postinstall.js, KORAINIT.md, src/cli/hooks.js, src/services/practice-hooks.js, src/practice/sync.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T02:18:08.261Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time AI-oriented file drop plus user-invoked agent configuration mutation. - **Rationale:** The package has an unconsented install-time AI-oriented file drop and explicit commands that mutate agent control surfaces. The more invasive mutations are user-invoked and no exfiltration, remote payload, or automatic broad control-surface mutation was found. - **Files touched:** KORAINIT.md, .claude/settings.json, AGENTS.md, CLAUDE.md, .cursor/rules/koragraph.mdc, .clinerules/koragraph.md, .windsurfrules, .github/copilot-instructions.md, GEMINI.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** An automatic postinstall copies an AI-oriented KORAINIT.md into the consumer project root., The copied file directly instructs coding agents to import existing instruction files and later modify agent instruction files., The explicit hooks command installs command hooks into a target repository’s Claude settings., The explicit practice sync feature writes managed content into several AI-agent instruction files. - **Evidence against:** The install hook only copies KORAINIT.md when absent; it does not directly alter standard agent configuration files., The Claude-hook and agent-file mutations are reached through named user commands, not the install lifecycle., No package runtime HTTP client or secret-exfiltration path was found in the inspected source., No self-dependency, remote payload loader, eval, or obfuscated install logic was found. ## Public findings ### 1.
