@polderlabs/bizar@4.2.4

Norse-pantheon multi-agent system for opencode — 13 agents across 4 cost tiers with cost-aware routing, plans, and a configurable agent harness. v4 ships as a single npm package bundling the dashboard server, opencode plugin, and typed SDK.

AI Security Review

scanned 3d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established by source inspection. The package has broad, package-aligned opencode setup and agent orchestration behavior, but it is activated by user CLI/dashboard actions rather than npm lifecycle execution.

Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs bizar commands such as bizar, bizar install, bizar dash, bizar update, or dashboard update actions
Impact
Installs or updates Bizar/opencode helper components and writes opencode configuration as documented; no confirmed unauthorized exfiltration, persistence, or destructive payload found
Mechanism
user-invoked opencode harness setup and dashboard/plugin orchestration
Rationale
The risky primitives are consistent with an opencode multi-agent CLI/dashboard that installs configuration, starts local services, and updates its own packages only after user invocation. I found no lifecycle hook, credential harvesting, covert outbound endpoint, destructive action, or unconsented AI-agent control-surface mutation sufficient to block publication.

Decision evidence

public snapshot
AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.
Evidence for block
  • cli/bin.mjs auto-runs ensureSetup on most bizar invocations when setup markers are missing
  • cli/install.mjs runPostInstall can copy agents/plugin config and install helper CLIs on user setup
  • install.sh contains curl/npm/uv installer logic for opencode-related dependencies
Evidence against
  • package.json has no preinstall/install/postinstall lifecycle hooks
  • cli/bin.mjs exposes a user-invoked CLI; child_process/fetch paths are dashboard/update/mod commands, not install-time exfiltration
  • plugins/bizar/index.ts and src files implement opencode plugin/background-agent features aligned with package purpose
  • config/opencode.json registers Bizar plugin/tools and disabled remote MCP entries; no credential harvesting code found
  • bizar-dash/src/server/update-store.mjs installs only declared @polderlabs packages with --ignore-scripts when user requests updates
  • secret-like scanner hit is in tests; inspected source paths show no hardcoded credential exfiltration
