Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs linzumi signup/start/connect or explicitly installs its service.
Impact
A compromised or maliciously authorized Linzumi workspace could direct an agent operating in user-approved project roots.
Mechanism
Remote coordination of a local Codex agent and optional supervisor persistence.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- CLI deliberately connects remotely steered Codex agents to trusted local folders.
- Documented local runner uses real environment, dotfiles, and branches.
- Explicit service command can install a persistent systemd supervisor.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Entrypoint only runs after the user invokes the linzumi binary.
- Remote-agent behavior and folder restrictions are documented.
- No direct eval/new Function call was found in reviewed runtime files.
