Future OpenCode agent sessions can receive package-authored binding instructions without an explicit setup command or consent prompt. - **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:** 0.51.0 - **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. LPM flags this version as an AI-agent control-surface risk. An npm postinstall hook changes the user's global OpenCode instruction control surface. It installs mandatory package-authored directives and enables them through the OpenCode configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-27T18:36:24.432Z - **Finished:** 2026-09-27T18:37:27.278Z - **Download time:** 505 ms - **Static scan time:** 2618 ms - **AI review time:** 59721 ms - **Total time:** 62846 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:** An npm postinstall hook changes the user's global OpenCode instruction control surface. It installs mandatory package-authored directives and enables them through the OpenCode configuration. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** Future OpenCode agent sessions can receive package-authored binding instructions without an explicit setup command or consent prompt. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T18:37:27.278Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bootstrap edits the OpenCode AGENTS file, writes a package instruction file, and adds that file to the OpenCode instruction list. - **Attack narrative:** Installing the package automatically runs a bootstrapper that modifies global OpenCode agent configuration. The installed content labels package directives as binding and registers them for subsequent agent sessions. This is an unconsented postinstall mutation of a broad AI-agent control surface. - **Rationale:** The package uses an automatic lifecycle hook to alter a user's global AI-agent instructions and configuration, rather than limiting setup to an explicit user command. The directive content attempts to control future agent behavior. - **Files touched:** ~/.config/opencode/AGENTS.md, ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall launcher for the bootstrap script., That script builds instructions which describe its directives as binding and mandatory., The automatic bootstrap removes content from the user's OpenCode AGENTS file, writes package instructions, and registers them in the global OpenCode configuration. - **Evidence against:** The bootstrap has an environment-variable opt-out, but it is not obtained as install-time consent. ## Affected versions and remediation This report applies to @herjarsa/omo-meta-governor@0.51.0. - Avoid installing @herjarsa/omo-meta-governor@0.51.0. 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.
