Future OpenCode agents can load package-authored directives without a separate user setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.45.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package changes the user's OpenCode control surface. It injects binding agent directives and registers them in the OpenCode configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-03T17:31:44.128Z - **Finished:** 2026-09-03T17:33:13.840Z - **Download time:** 1011 ms - **Static scan time:** 2967 ms - **AI review time:** 85732 ms - **Total time:** 89712 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package changes the user's OpenCode control surface. It injects binding agent directives and registers them in the OpenCode configuration. - **Trigger:** npm automatically runs postinstall when this package is installed. - **Impact:** Future OpenCode agents can load package-authored directives without a separate user setup command. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T17:33:13.840Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes agent instructions and patches OpenCode configuration. - **Attack narrative:** The npm postinstall hook invokes a script that creates a home-directory OpenCode plugin instruction file. The file declares its directives binding, then the script patches the user's OpenCode configuration to load it. This is automatic mutation of a broad AI-agent control surface during installation rather than explicit user-command setup. - **Rationale:** The package performs unconsented postinstall mutation of OpenCode configuration and injects binding instructions into future agent sessions. This is concrete install-hook abuse even though no secret theft was confirmed. - **Files touched:** ~/.config/opencode/plugins/omo-meta-governor/instructions.md, ~/.config/opencode/opencode.jsonc, ~/.config/opencode/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package automatically runs a bootstrap script during npm postinstall., The bootstrap targets the user's OpenCode configuration and creates a plugin instructions file containing binding directives., The postinstall script writes that file and adds it to the user's OpenCode instructions configuration without an explicit user command. - **Evidence against:** No credential harvesting or network exfiltration was established from the inspected install script., The install script offers an environment-variable opt-out, but it is not enabled by default. ## Public findings ### 1.
