A package-controlled prompt can cause an agent to add persistent Koragraph instructions and hooks to a consumer repository. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation silently adds KORAINIT.md to the consumer project. That file is an agent prompt that directs subsequent writes into broadly loaded AI-agent instruction files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-09-05T03:02:08.521Z - **Finished:** 2026-09-05T03:03:40.702Z - **Download time:** 512 ms - **Static scan time:** 7853 ms - **AI review time:** 83815 ms - **Total time:** 92181 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation silently adds KORAINIT.md to the consumer project. That file is an agent prompt that directs subsequent writes into broadly loaded AI-agent instruction files. - **Trigger:** npm installation followed by a coding agent opening the copied KORAINIT.md - **Impact:** A package-controlled prompt can cause an agent to add persistent Koragraph instructions and hooks to a consumer repository. - **Evidence paths:** package.json, scripts/postinstall.js, KORAINIT.md, src/practice/sync.js, src/services/practice-hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T03:03:40.702Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time prompt seeding that induces AI-agent control-file mutation - **Attack narrative:** On npm install, the package copies KORAINIT.md into the consuming project without consent. The copied file directly instructs a coding agent to execute Koragraph commands. Its requested sync operation writes a managed block into AGENTS.md and other loaded agent-instruction files; the package also provides code to register Claude hook commands. This is an install-seeded path to persistent control of a foreign repository’s AI-agent context. - **Rationale:** The automatic lifecycle write is not benign documentation: it plants an AI-directed instruction file in the consumer project that explicitly drives broad agent control-surface changes. This satisfies unconsented install-time AI-agent control-surface mutation. - **Files touched:** KORAINIT.md, AGENTS.md, CLAUDE.md, .cursor/rules/koragraph.mdc, .clinerules/koragraph.md, .windsurfrules, .github/copilot-instructions.md, GEMINI.md, .claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., Postinstall copies an agent-directed instruction file into the consumer project root., The copied file instructs coding agents to run a command that modifies loaded agent instruction files., The sync implementation writes managed content into several agent control files, including AGENTS.md., A separate hook installer can register package scripts in Claude settings. - **Evidence against:** No runtime network endpoint or credential-exfiltration code was found in the inspected paths., The Claude hook installer is normally reached through an explicit CLI command. ## Public findings ### 1.
