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:** 5.0.1 - **Selected version is latest:** No - **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. Source inspection found an opt-in self-update and first-party Claude plugin reconciliation path, but no unconsented install-time mutation, data exfiltration, remote payload execution, or broad foreign-agent control-surface overwrite. The static malicious label is not supported by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-08-28T08:30:41.577Z - **Finished:** 2026-08-28T08:32:03.180Z - **Download time:** 1521 ms - **Static scan time:** 17324 ms - **AI review time:** 62757 ms - **Total time:** 81603 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:** The package provides an opt-in updater that can install its latest npm release and synchronize its own Claude plugin cache and registry entry. No install-time mutation or credential exfiltration was confirmed. - **Trigger:** The user runs the update command, or has explicitly enabled silent auto-updates. - **Impact:** A later package release can be installed and the package's own Claude plugin files and registry metadata can be refreshed. - **Evidence paths:** package.json, dist/features/auto-update.js, dist/features/rate-limit-wait/daemon.js, dist/tools/ast-tools.js, bin/oh-my-claudecode.js, skills/project-session-manager/tests/test-jira-provider.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-28T08:32:03.180Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opt-in package self-update and first-party Claude plugin cache reconciliation. - **Rationale:** Source inspection found an opt-in self-update and first-party Claude plugin reconciliation path, but no unconsented install-time mutation, data exfiltration, remote payload execution, or broad foreign-agent control-surface overwrite. The static malicious label is not supported by the inspected source. - **Files touched:** ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/cache/omc/oh-my-claudecode, ~/.claude/.omc-version.json, ~/.claude/.omc-silent-update.json - **Network endpoints:** https://api.github.com/repos/Yeachan-Heo/oh-my-claudecode, https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The update command installs the latest package globally and then refreshes its Claude plugin cache., The updater changes only registry entries whose plugin ID is this package's own OMC plugin., Silent updating can run without interaction, but only after the user has enabled it in the package configuration. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Release checks target the package's declared GitHub repository., The credential token is used as GitHub API authorization, not sent to an unrelated endpoint., The daemon uses an explicit environment allowlist intended to exclude tokens and credentials. ## Affected versions and remediation This report applies to oh-my-claude-sisyphus@5.0.1. - Review the evidence and your use of oh-my-claude-sisyphus@5.0.1 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.
