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

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic detached server and possible native rebuild are material install-hook risks. The inspected credential and agent-integration code is explicit and package-aligned, so the source does not establish malware intent.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation, unless CI or CODEMAN_NO_AUTOSTART is set

Impact

An unexpected background service and dependency mutation can occur during installation.

Mechanism

postinstall process spawning and native dependency rebuild

AI rationale

Evidence

package.jsonscripts/postinstall.jsscripts/fix-node-pty.mjsdist/index.jsnode_modules/node-pty

Network endpoints1

127.0.0.1

Decision evidence

public snapshot

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

Evidence for warning

The package runs a postinstall script automatically.
Postinstall launches a detached Codeman web-server process unless an environment opt-out is set.
Postinstall can rebuild the native node-pty dependency from source.

Evidence against

No runtime dependency on aicodeman itself was found.
The Claude credential path is used for a visible voice relay to api.anthropic.com, not an undisclosed endpoint.
Agent skill installation is an explicit CLI command, not an install hook.
