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:** 0.1.26 - **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. This is a first-party OpenCode plugin whose postinstall still changes agent permissions and a user environment variable without a separate opt-in. That is guarded extension lifecycle risk, not a foreign-agent hijack or a hidden exfiltration chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-09-26T11:20:35.356Z - **Finished:** 2026-09-26T11:22:12.909Z - **Download time:** 779 ms - **Static scan time:** 402 ms - **AI review time:** 96372 ms - **Total time:** 97553 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:** Install and import mutate the user's OpenCode control surface without a separate consent prompt. The change registers this package as a plugin, enables web search when unset, and turns on OPENCODE\_ENABLE\_EXA. - **Trigger:** npm postinstall, and later import of dist/index.js by OpenCode. - **Impact:** OpenCode loads superoc and may gain web search plus the EXA feature without an explicit setup command. Credentials are not sent to an unrelated host by this path. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js, dist/antigravity.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T11:22:12.909Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall rewrites OpenCode config, plugin shim, local package copy, and a placeholder auth entry, and on Windows sets a user environment variable. The plugin module also forces OPENCODE\_ENABLE\_EXA. - **Rationale:** This is a first-party OpenCode plugin whose postinstall still changes agent permissions and a user environment variable without a separate opt-in. That is guarded extension lifecycle risk, not a foreign-agent hijack or a hidden exfiltration chain. - **Files touched:** ~/.config/opencode/opencode.json, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/package.json, ~/.config/opencode/plugins/superoc.js, ~/.config/opencode/node\_modules/superoc, ~/.local/share/opencode/auth.json - **Network endpoints:** http://127.0.0.1:51121/v1beta ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** npm postinstall runs scripts/postinstall.js automatically., That script registers superoc in the OpenCode plugin lists and sets permission.websearch to allow when unset., It also writes a superoc dependency into the OpenCode config package.json and copies this package into that config's node\_modules., On Windows the same install sets the user environment variable OPENCODE\_ENABLE\_EXA through powershell., Loading dist/index.js sets OPENCODE\_ENABLE\_EXA when it is not already set., Antigravity OAuth and the local proxy target Google and localhost, matching the stated rotator. - **Evidence against:** Published package.json does not depend on superoc, so there is no nested lifecycle self-install., Network calls stay on Google, NVIDIA, and 127.0.0.1 rather than an unrelated recipient., No eval, remote payload fetch, or secret upload was found., Writes stay inside OpenCode config and data directories for this plugin. ## Affected versions and remediation This report applies to superoc@0.1.26. - Review the evidence and your use of superoc@0.1.26 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.
