clean-ddd-hexagonal — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited clean-ddd-hexagonal (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Use these related patterns to solve a concrete domain or dependency problem. This is an opinionated synthesis, not a mandatory folder layout. The user's explicit instructions take precedence over this skill's guidelines.
Start from the requested behavior, existing domain model, and current dependencies. Preserve the project's language and architecture unless changing them is part of the task. Simple CRUD can remain simple; team size, entity count, and file length do not determine whether DDD is appropriate.
| Design question | Relevant pattern |
|---|---|
| What language and consistency rules describe the business? | DDD, bounded contexts, aggregates |
| Which way should source dependencies point? | Clean/Onion Architecture |
| How can the application use different interfaces or infrastructure? | Hexagonal ports and adapters |
| Do reads and writes need different models? | CQRS |
| Must state be reconstructed from an event history? | Event Sourcing |
If a business invariant is unknown, identify the specific missing rule and continue work that does not depend on it. Do not invent business behavior or require a discovery workshop for a local fix.
Deliver the requested model, patch, or review with affected boundaries and the tradeoffs that explain them. Validate changed invariants and adapter contracts at the appropriate level; an architecture question does not require implementing every pattern.
