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:** 0.8.0 - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. On OpenCode plugin initialization, the package downloads embedding assets and force-copies its bundled agent/command definitions into OpenCode directories. This is a first-party agent-extension lifecycle write; no concrete exfiltration or foreign control-surface takeover was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-08-18T00:10:44.220Z - **Finished:** 2026-08-18T00:12:02.221Z - **Download time:** 517 ms - **Static scan time:** 2918 ms - **AI review time:** 74563 ms - **Total time:** 78001 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:** On OpenCode plugin initialization, the package downloads embedding assets and force-copies its bundled agent/command definitions into OpenCode directories. This is a first-party agent-extension lifecycle write; no concrete exfiltration or foreign control-surface takeover was established. - **Trigger:** OpenCode loads the plugin; postinstall may also invoke its Bun helper. - **Impact:** Bundled instructions become available to OpenCode agents and model files are persisted locally. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/infrastructure/composition-root.js, dist/ensure-models.js, agent/memory-hints.md - **Review source:** ai\_review - **Reviewed:** 2026-08-18T00:12:02.221Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** model download plus automatic first-party agent/command installation - **Rationale:** This is not concrete malware, but automatic force-copying of agent instructions into a global OpenCode control surface is a package-owned agent extension lifecycle risk. Warn rather than block under the stated policy. - **Files touched:** agent/, commands/, ~/.config/opencode/agent, ~/.config/opencode/commands, ~/.config/opencode/models/Xenova/ - **Network endpoints:** https://huggingface.co/Xenova/all-MiniLM-L6-v2/resolve/main/onnx/model\_quantized.onnx, https://huggingface.co/Xenova/gte-small/resolve/main/onnx/model\_quantized.onnx, https://huggingface.co/Xenova/ms-marco-MiniLM-L-6-v2/resolve/main/onnx/model\_quantized.onnx ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** postinstall conditionally launches a Bun helper., Plugin initialization downloads models and force-copies bundled agent and command files into OpenCode's global control directories., Bundled agent guidance instructs agents to always query and store memory., Model downloads target Hugging Face URLs. - **Evidence against:** No credential harvesting or non-local data exfiltration was found in inspected runtime code., No eval/vm or remote code-loading path was found., The writes are package-aligned OpenCode plugin assets, not foreign-agent configuration mutation. ## Affected versions and remediation This report applies to opencode-fractal-memory@0.8.0. - Review the evidence and your use of opencode-fractal-memory@0.8.0 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.
