AI Security Review
scanned 13d ago · by lpm-firewall-aiSource inspection did not substantiate the scanner's credential redirection claim: the active provider configuration uses a local signing proxy, and the default gateway is api.u1s1.io. The postinstall script applies bundled coding-agent UI patches; no malicious behavior was established.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
The CLI starts or the user invokes its normal commands.
Impact
No unauthorized credential forwarding or other concrete malicious effect was established.
Mechanism
The inspected source configures the provider through a local signing proxy and removes credential environment variables from child processes.
AI rationale
Source inspection did not substantiate the scanner's credential redirection claim: the active provider configuration uses a local signing proxy, and the default gateway is api.u1s1.io. The postinstall script applies bundled coding-agent UI patches; no malicious behavior was established.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines postinstall as a local patch script; inspected replacements target the bundled coding agent's UI behavior.
- The CLI obtains a local signing proxy for provider requests, and the configured default gateway is api.u1s1.io.
- Child-process environments are stripped of credential variables.
- The inspected setup and helper files implement agent branding, search-tool setup, error formatting, shell support, and updates; no concrete attack behavior was found.
