@herjarsa/omo-meta-governor@0.56.0
Self-judging agent orchestration layer for OpenCode. Reads memory, scores sessions, dispatches decisions.
AI Security Review
scanned 7d ago · by lpm-firewall-aiThe 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.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
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.
Mechanism
The postinstall script writes an instructions file and adds its path to the global OpenCode instructions setting without asking for consent.
Policy 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.
AI 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.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.
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.
