Consumer repositories can gain package-controlled instructions in AGENTS.md, CLAUDE.md, and other agent files, plus command hooks in .claude/settings.json. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package drops KORAINIT.md into the consuming project. That file instructs any coding agent that reads it to rewrite broad agent instruction files and can lead to executable Claude hook registration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T13:46:46.363Z - **Finished:** 2026-09-07T13:48:04.781Z - **Download time:** 251 ms - **Static scan time:** 8129 ms - **AI review time:** 70037 ms - **Total time:** 78418 ms The recorded confidence comes from the underlying analysis.

That file instructs any coding agent that reads it to rewrite broad agent instruction files and can lead to executable Claude hook registration. - **Trigger:** npm installation runs postinstall; a coding agent subsequently reads the planted KORAINIT.md. - **Impact:** Consumer repositories can gain package-controlled instructions in AGENTS.md, CLAUDE.md, and other agent files, plus command hooks in .claude/settings.json. - **Evidence paths:** scripts/postinstall.js, KORAINIT.md, src/practice/sync.js, src/services/practice-hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T13:48:04.781Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-planted agent instructions drive persistent AI-agent control-surface changes. - **Attack narrative:** The postinstall hook writes KORAINIT.md into the consumer project without consent. The planted file directly addresses coding agents and tells them to execute koragraph commands. Its prescribed sync operation writes managed content to AGENTS.md and other agent instruction files, and the package includes code to register executable hooks in a target repository's Claude settings. This is an install-driven path from a consumer project mutation to persistent control of broad AI-agent instruction and hook surfaces. - **Rationale:** This is unconsented postinstall mutation of a foreign project that plants instructions intended to cause broad AI-agent control-surface writes. The source establishes the complete install-to-agent-control chain, so it meets the publish-block policy. - **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:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Install automatically copies an agent-directed instruction file into the consumer project root., The dropped file tells a coding agent to read it fully and act, then directs it to rewrite agent instruction files., The requested sync creates or changes broad agent instruction files, including AGENTS.md., The package can also add executable hooks to a target repository's Claude settings. - **Evidence against:** No self-dependency or secret-exfiltration endpoint was found in the inspected manifest and install script., The direct postinstall action is limited to copying KORAINIT.md when it is absent. ## Affected versions and remediation This report applies to koragraphmcp@0.1.6. - Avoid installing koragraphmcp@0.1.6. 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.
