# Security Threat Model
## Purpose
Use this skill before implementing or approving security-sensitive changes. It complements `auth-security` and `server-security` by mapping assets, attackers, trust boundaries, and concrete controls.
## Scope First
Identify:
1. Assets: credentials, tokens, user data, tenant data, money movement, admin actions.
2. Actors: anonymous user, authenticated user, tenant admin, internal operator, compromised dependency.
3. Trust boundaries: browser/server, service/service, tenant/tenant, CI/runtime, third-party callbacks.
4. Entry points: API routes, CLI commands, jobs, webhooks, uploads, config files.
