Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** npm installation automatically changes the user's global OpenCode agent-instruction file. The injected directives apply to agents that do not load this package. - **Trigger:** Installing the package, which invokes its postinstall hook unless the user pre-sets the opt-out variable. - **Impact:** Unconsented persistent modification of a broad AI-agent control surface can influence future agent behavior. - **Evidence paths:** package.json, scripts/bootstrap-agents-md.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T10:55:39.192Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes SYSTEM-NUDGE directives into global AGENTS.md. - **Attack narrative:** During npm installation, package.json launches the bootstrap script. It resolves the user's home directory and targets ~/.config/opencode/AGENTS.md, creating its directory if needed. It appends a managed block of SYSTEM-NUDGE directives explicitly intended to affect agents outside the plugin process, then writes the result. The opt-out only works if set before installation, so ordinary installation mutates a global agent control file without an explicit setup command or consent prompt. - **Rationale:** This is a concrete automatic postinstall mutation of a foreign, global AI-agent control surface. The behavior meets the install-control-surface blocking rule regardless of the absence of observed credential exfiltration. - **Files touched:** scripts/bootstrap-agents-md.mjs, ~/.config/opencode/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a bootstrap script automatically in npm postinstall., The bootstrap targets the user's global OpenCode AGENTS.md control file., It injects SYSTEM-NUDGE directives intended to reach agents outside the plugin process., The script creates parent directories and writes the merged directives without an interactive consent step. - **Evidence against:** The bootstrap has an environment-variable opt-out, but it is not required before the automatic postinstall runs., No lifecycle network request or credential exfiltration was found in the inspected bootstrap script. ## Affected versions and remediation This report applies to @herjarsa/omo-meta-governor@0.38.9. - Avoid installing @herjarsa/omo-meta-governor@0.38.9. 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.
