Agent observability and knowledge capture layer for AI coding tools.

AI Security Review

scanned 11h ago · by lpm-firewall-ai

No confirmed attack surface was identified in the inspected behavior. The agent-related excerpts show detection and platform metadata, while the inspected network request is loopback-only.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

Running the CLI performs local agent detection and local health checks; npm postinstall invokes native-backend reconciliation.

Impact

The inspected behavior does not establish credential exfiltration or unconsented mutation of an agent configuration surface.

Mechanism

The reconciler checks the installed optional backend version and, if it differs, invokes npm to install the matching package version with lifecycle scripts disabled.

AI rationale

Source inspection found agent discovery metadata, loopback health checks, and a narrowly targeted native backend reconciliation. These excerpts do not support the scanner's command-output exfiltration claim or establish malicious behavior.

Evidence

package.json.output/cli.js.output/server/_ssr/router-zFIFa6Tt.mjsscripts/reconcile-native-backend.mjs

Decision evidence

public snapshot

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

Why the final policy warns

The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior.
