Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface was found. The package is a user-invoked autonomous development CLI that can run agents and contact its configured service in GitHub Actions mode. - **Trigger:** A user runs a CLI command or configures the package in a GitHub Actions workflow. - **Impact:** The intended tool can modify a selected project and use configured credentials, but no unconsented install-time or hidden attack chain was found. - **Evidence paths:** package.json, dist/bin/kody.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T20:04:37.825Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runs development-agent workflows and authenticated service requests. - **Rationale:** The flagged behaviors are declared, user- or workflow-invoked functions of an autonomous development engine. Source inspection found no lifecycle execution, foreign package overwrite, persistent credential redirect, or concrete exfiltration chain. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The explicit \`serve claude\` command starts Claude Code with permission prompts disabled., GitHub Actions mode sends authenticated requests to the package service endpoint. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The Claude endpoint override is only passed to the spawned child process and defaults to a localhost LiteLLM proxy., The package copies its bundled Claude binary to a temporary directory; it does not overwrite another installed package., No hidden credential harvesting, unconditional exfiltration, or install-time persistence was found in the inspected entrypoint. ## Affected versions and remediation This report applies to @kody-ade/kody-engine@0.4.637. - Review the evidence and your use of @kody-ade/kody-engine@0.4.637 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.
