Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. A foreign AI-agent control surface is altered without an explicit user command, allowing package directives to influence future agent behavior. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.39.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. On every npm installation, the package changes the user's OpenCode instruction surface. It adds package-authored directives that claim to be binding and registers them in the OpenCode configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T05:32:08.788Z - **Finished:** 2026-09-14T05:32:51.897Z - **Download time:** 1539 ms - **Static scan time:** 2237 ms - **AI review time:** 39331 ms - **Total time:** 43109 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 every npm installation, the package changes the user's OpenCode instruction surface. It adds package-authored directives that claim to be binding and registers them in the OpenCode configuration. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** A foreign AI-agent control surface is altered without an explicit user command, allowing package directives to influence future agent behavior. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T05:32:51.897Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic OpenCode instruction injection and configuration mutation. - **Attack narrative:** Installing the package automatically invokes its bootstrap script. That script creates or changes an OpenCode plugin instructions file, inserts directives described as binding, and changes the user's OpenCode configuration so the file is loaded. The opt-out does not establish consent because the mutation is the default postinstall behavior. - **Rationale:** This is an unconsented postinstall mutation of a broad AI-agent control surface, with package-authored instructions registered for future use. It meets the install-control-surface block policy. - **Files touched:** ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs a bootstrap script after npm installation., The script writes binding directives into the user's OpenCode plugin instructions., The script modifies the user's OpenCode configuration to load those instructions. - **Evidence against:** The install script contains an environment-variable opt-out and catches errors., No credential harvesting or external exfiltration was confirmed in the install script. ## Affected versions and remediation This report applies to @herjarsa/omo-meta-governor@0.39.5. - Avoid installing @herjarsa/omo-meta-governor@0.39.5. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
