🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for Happy Coder, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
Overview
Happy Coder is an open-source mobile/web client for Claude Code and Codex. You run `happy claude` (a wrapper around the CLI) on your machine and control the session from your phone; it sends push notifications when Claude needs permission or errors and keeps sessions end-to-end encrypted. As a CLI wrapper it intercepts the agent session and relays it to remote devices.
