AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe scanner’s credential and child-process indicators map to disclosed, user-invoked CLI functionality, not an install-time malicious chain. Warn because the package has real credential-sync and agent-extension capabilities.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs `postboi init`, `postboi env push`, or related CLI setup.
Impact
Provider credentials may be sent to the authenticated Postboi account; an opted-in project skill may be written.
Mechanism
User-invoked credential synchronization and first-party agent-skill setup.
AI rationale
The scanner’s credential and child-process indicators map to disclosed, user-invoked CLI functionality, not an install-time malicious chain. Warn because the package has real credential-sync and agent-extension capabilities.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- CLI can upload provider credential values to the Postboi API.
- `env push` reads recognized project env credentials and sends them.
- CLI can create a first-party Claude skill after an interactive confirmation.
Evidence against
- No preinstall/install/postinstall hook; prepare only runs SvelteKit sync.
- Credential transfer is tied to explicit CLI setup or `env push`, with authenticated Postboi API requests.
- The agent-skill path is package-owned and installation is confirmed by the user.
