Mission control for AI coding agents - run 20 autonomous agents with real-time monitoring and session persistence

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The scanner's claimed AI-agent-control hijack is not supported by the inspected source. However, install-time detached process launch and Git-hook mutation are real lifecycle side effects that warrant a warning.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

npm postinstall; service persistence requires `codeman service install`

Impact

Unexpected local server and source-checkout hook mutation; no confirmed exfiltration or foreign AI-agent control-surface mutation.

Mechanism

install hook process launch and development Git-hook write

AI rationale

Evidence

package.jsonscripts/postinstall.jsdist/service-installer.jsdist/web/self-update.jsdist/web/server.js.git/hooks/pre-commitdist/index.js

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

scripts/postinstall.js auto-starts a detached web-server process on install.
scripts/postinstall.js writes .git/hooks/pre-commit when installed from a source checkout.
dist/service-installer.js can create user launchd/systemd services via explicit CLI action.

Evidence against

Postinstall binds/checks only 127.0.0.1 and has a CODEMAN_NO_AUTOSTART opt-out.
No postinstall credential harvesting, remote download, or external network call was found.
Service creation is exposed as explicit `codeman service install`, not invoked by postinstall.
Self-update is limited to git installs and uses GitHub release/tag checks after a user update action.
