AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection found credential synchronization and optional skill/project setup only behind explicit CLI flows, with no hidden exfiltration or install-time execution chain. Static credential and child-process findings are package-aligned CLI functionality.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicit postboi init or postboi env push command
Impact
Configured provider credentials may be sent to the user's Postboi account for team synchronization.
Mechanism
Authenticated, user-invoked credential synchronization
AI rationale
Source inspection found credential synchronization and optional skill/project setup only behind explicit CLI flows, with no hidden exfiltration or install-time execution chain. Static credential and child-process findings are package-aligned CLI functionality.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- Explicit CLI credential-sync capability PUTs selected variables to the Postboi API.
Evidence against
- The only install hook is prepare running SvelteKit sync; it does not invoke the package CLI.
- Credential upload requires a POSTBOI_TOKEN and occurs from explicit init/env workflows.
- Agent-skill installation is an interactive confirmation; no install-time agent-control mutation exists.
