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 inspected behavior supports a warning for explicit agent plugin setup and configuration changes, but not a malicious verdict: the manifest has no install hook and these actions require user commands. Credential bundling is likewise selected by the caller for a configured remote session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-09T09:40:51.689Z - **Finished:** 2026-10-09T09:41:29.708Z - **Download time:** 511 ms - **Static scan time:** 2980 ms - **AI review time:** 34528 ms - **Total time:** 38019 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 explicit plugin-management command can install and register agent plugins, and a separate installer option can save a shell or curl installer to run on a later sync. This is a guarded, user-invoked agent configuration capability; no automatic install-time attack was identified. - **Trigger:** A user runs the plugin add command and later runs plugin sync. - **Impact:** The chosen plugin or installer can add capabilities to the user’s agent environment. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T09:41:29.708Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command installs npm plugin packages and writes agent MCP configuration, or saves a caller-provided installer for later Pod setup. - **Rationale:** The inspected behavior supports a warning for explicit agent plugin setup and configuration changes, but not a malicious verdict: the manifest has no install hook and these actions require user commands. Credential bundling is likewise selected by the caller for a configured remote session. - **Files touched:** dist/plugin.js, dist/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest has no install lifecycle hooks; its main export is dist/index.js., The explicit plugin command can register npm package binaries with Claude, Codex, and agy., The plugin installer command persists a user-specified installer for execution during a later sync., Plugin configuration writes an MCP server entry to Codex’s config.toml., Claude enrollment hooks are installed through an explicit --install-hooks option., Selected CLI authentication files are bundled for remote sessions when the caller opts in via tools. - **Evidence against:** No source evidence establishes that plugin setup runs automatically during npm installation., The inspected credential-bundling path is opt-in and passes credentials to the configured remote-session flow. ## Affected versions and remediation This report applies to @sentropic/h2a-runtime@0.97.1. - Review the evidence and your use of @sentropic/h2a-runtime@0.97.1 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.
