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. OpenCode agents may follow package-authored directives in later sessions. - **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:** 0.56.0 - **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. The postinstall hook automatically modifies global agent configuration and loads package-authored binding directives without affirmative consent. This meets the policy for blocking unconsented lifecycle mutation of an AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-16T14:50:02.622Z - **Finished:** 2026-10-16T14:51:16.770Z - **Download time:** 2552 ms - **Static scan time:** 2747 ms - **AI review time:** 68847 ms - **Total time:** 74148 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 automatic installer changes the user’s global OpenCode configuration to load package-authored instructions that claim binding authority over agent behavior. - **Trigger:** Installing the package with npm, unless the installer sets the bootstrap opt-out environment variable. - **Impact:** OpenCode agents may follow package-authored directives in later sessions. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-16T14:51:16.770Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script writes an instructions file and adds its path to the global OpenCode instructions setting without asking for consent. - **Attack narrative:** During npm installation, the postinstall script adds a package-authored instructions file to the user’s global OpenCode configuration. That file labels the plugin’s directives as binding, changing instructions applied to OpenCode agents without affirmative consent. An environment-variable opt-out exists, but the default install path performs the mutation. - **Rationale:** The postinstall hook automatically modifies global agent configuration and loads package-authored binding directives without affirmative consent. This meets the policy for blocking unconsented lifecycle mutation of an AI-agent control surface. - **Files touched:** scripts/bootstrap-agents-md.mjs, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/plugins/omo-meta-governor/instructions.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its bootstrap script automatically during postinstall., The bootstrap runs on its default path; only a specific environment setting skips it., The script targets the user’s global OpenCode configuration and a plugin instructions file., It adds the plugin instructions file to the global instructions setting and writes the updated configuration., It writes binding directives into the instructions file, giving the plugin’s instructions authority over agent behavior. ## Affected versions and remediation This report applies to @herjarsa/omo-meta-governor@0.56.0. - Avoid installing @herjarsa/omo-meta-governor@0.56.0. 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.
