Self-judging agent orchestration layer for OpenCode. Reads memory, scores sessions, dispatches decisions.

AI Security Review

scanned 4h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. On npm installation, the package changes global OpenCode agent instructions and configuration. It injects directives presented as binding before registering the injected file for use.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation runs the postinstall script unless the user has pre-set its opt-out environment variable.

Impact

An installed dependency can alter the behavior and instruction hierarchy of OpenCode agents without an explicit setup command.

Mechanism

Automatic mutation of global AI-agent instructions and configuration.

Policy narrative

Installing the package automatically invokes its bootstrapper. The script removes a prior AGENTS.md snippet, creates or changes a global OpenCode plugin instruction file containing directives declared binding, and adds that file to the user's OpenCode configuration. This is an unconsented postinstall modification of a broad AI-agent control surface.

Rationale

The package has a concrete automatic install-time chain that modifies global AI-agent instructions and configuration, rather than requiring an explicit user setup action. The injected content asserts authority over agent behavior, meeting the install-control-surface blocking policy.
