P4 Code coding agent server and command-line client

AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source inspection found no lifecycle hooks or concrete attack behavior. The scanner’s shell and credential findings are not supported by the inspected worker entry, which performs Claude history operations; local shell execution is consistent with the package’s coding-agent function.

Static reason

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

Trigger

The CLI runs when invoked; the worker runs when the CLI requests a Claude history operation.

Impact

No external credential disclosure, reverse shell, or agent configuration change was established from the inspected behavior.

Mechanism

The worker validates a history request and dispatches only message retrieval or session forking. The observed Bash process uses local pipes and a working directory.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json defines a CLI entry and no lifecycle scripts.
The flagged worker accepts only Claude history operations: reading session messages or forking a session.
The shell code starts a local Bash process with piped input and output; this is consistent with a coding agent’s command execution capability.
The flagged configuration location reads Claude configuration and project directory values and compares paths; the inspected code does not show an agent configuration write.
The other flagged files inspected are dependency or frontend asset bundles.

Evidence against

The package exposes command execution capability, but the inspected worker entry does not dispatch shell commands.
No credential transfer, reverse network shell, or agent configuration mutation was established in the inspected source.
