AI Security Review

scanned 5d ago · by lpm-firewall-ai

The source shows automatic, persistent setup that can steer agents and installs bundled skill instructions globally, but it does not establish credential theft or another concrete attack. Treat the package-aligned integration and unverified bundled content as residual lifecycle risk and warn.

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

npm installation runs the postinstall script; initializing either exported runtime bundle also triggers the bundled skill setup.

Impact

The package can influence agent behavior across sessions without an affirmative setup step; the archive contents remain unverified.

Mechanism

The postinstall script writes binding directives and registers their file with OpenCode. Runtime setup extracts a bundled archive and copies skill instruction files into the global agent skills directory.

AI rationale

Evidence

package.jsonscripts/bootstrap-agents-md.mjsdist/index.jsdist/lib.js.lpm-inspection-mEeHKt/0-745de96d43e5.txt~/.config/opencode/plugins/omo-meta-governor/instructions.md~/.config/opencode/opencode.jsonc~/.agents/skills/<skill>/SKILL.md

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The npm postinstall hook runs the bootstrap script automatically.
The script writes package instructions with binding directives to the user's global OpenCode plugin configuration; skipping requires an environment opt-out.
The script adds its instruction file to the global OpenCode instructions array.
Both exported runtime bundles extract the bundled archive and copy its skill instruction files into the user's global agent skills directory, while skipping existing modified skill files.
The trusted artifact analysis could not inspect the archive because of a TAR entry or terminator limitation.

Evidence against

The setup targets this package's own OpenCode plugin instructions and skills.
The inspected setup code does not establish credential transfer or destructive behavior.
