Frequently Asked Questions

Architecture and operational details for Cappy

Cappy ensures quality through a robust 'hook pipeline' featuring 30+ validation hooks that enforce quality gates like PII guarding, evidence chain tracking, and claim verification. For security, all tool executions are isolated within a container sandbox (Podman/Docker) with network isolation and read-only mounts, preventing data exfiltration and ensuring secure processing of untrusted files.
