Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.2.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source establishes an unconsented install-time project mutation and user-command-driven agent and Git hook persistence. It does not establish the narrower concrete malicious chain required for a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-12T12:57:38.511Z - **Finished:** 2026-09-12T12:58:41.150Z - **Download time:** 506 ms - **Static scan time:** 5912 ms - **AI review time:** 56221 ms - **Total time:** 62639 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package locally drops an agent-facing onboarding file into the consumer project. Running its ingest workflow installs persistent Git and Claude Code hooks, and its sync workflow can write agent instruction files. - **Trigger:** Local npm installation, followed by an agent acting on KORAINIT.md or a user running koragraph ingest or practice sync. - **Impact:** The package can steer coding-agent behavior and arrange later local command execution in a target repository. - **Evidence paths:** scripts/postinstall.js, KORAINIT.md, src/cli/ingest.js, src/services/practice-hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T12:58:41.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Consumer-project onboarding and agent-extension hook installation. - **Rationale:** The source establishes an unconsented install-time project mutation and user-command-driven agent and Git hook persistence. It does not establish the narrower concrete malicious chain required for a publish block. - **Files touched:** KORAINIT.md, .claude/settings.json, .git/hooks/post-commit, .git/hooks/post-checkout, .git/hooks/post-merge, .git/hooks/post-rewrite, AGENTS.md, CLAUDE.md, .cursor/rules/koragraph.mdc, .clinerules/koragraph.md, .windsurfrules, .github/copilot-instructions.md, GEMINI.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The automatic postinstall hook writes KORAINIT.md into a consumer project without an explicit setup command., The installed onboarding file instructs an agent to create or refresh agent instruction files for several vendors., The ingest command automatically installs Claude Code command hooks and Git hooks unless the user opts out., The hook installer writes command entries to the target repository's .claude/settings.json. - **Evidence against:** The postinstall hook only copies a local Markdown file and exits for global installs., No credential harvesting, outbound network client, remote payload download, or self-dependency was found in the inspected paths., Agent and Git hook changes occur through package commands, not directly during postinstall. ## Affected versions and remediation This report applies to koragraphmcp@0.2.0. - Review the evidence and your use of koragraphmcp@0.2.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
