CEO-in-a-Box: AI department hierarchy plugin for OpenCode

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. This is an OpenCode agent-extension package that mutates the workspace control surface at plugin runtime by syncing its own agents, commands, rules, AGENTS.md, and Makefile. The behavior is package-aligned but broad enough to warrant a warning rather than a block.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

OpenCode loads the plugin or user invokes ceo-* commands

Impact

Workspace AI-agent configuration and command surface can be changed; user-invoked commands can install MCP packages or skills.

Mechanism

first-party agent extension setup and user-invoked tooling

Rationale

Source inspection shows first-party OpenCode extension behavior with broad agent-control-surface writes at plugin runtime, but no npm lifecycle hook, credential harvesting, exfiltration, stealth persistence, or remote payload execution. Under the policy this fits an agent extension lifecycle risk warning, not a malicious publish block.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

scripts/index.js server() calls applySync(workspaceRoot,false,...) on plugin load, copying package agents/commands/rules into .opencode.
scripts/sync.js can copy AGENTS.md and Makefile into workspace and .opencode/{agents,commands,rules}.
scripts/mcp.js user command can run npm install for built-in MCP server packages and write .mcp.json.
scripts/download-skill.js can clone/download external skills from user-supplied URLs, then install them after scans/prompts.

Evidence against

package.json has no preinstall/install/postinstall lifecycle hooks and main is scripts/index.js.
Agent permissions registered in scripts/index.js use ask for bash/edit rather than auto-allow.
scripts/env-check.js only checks tool versions and env var presence; it does not print secret values or exfiltrate.
scripts/validate.js/setup.js/lint.js execute local project tools only when invoked as commands, not at install time.
No hardcoded exfiltration endpoint or remote payload execution found in inspected source.
