Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads domain-cloud-native automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.
Cloud-Native Domain
Layer 3: Domain Constraints
Domain Constraints → Design Implications
| Domain Rule | Design Constraint | Rust Implication |
|---|---|---|
| 12-Factor | Config from env | Environment-based config |
| Observability | Metrics + traces | tracing + opentelemetry |
| Health checks | Liveness/readiness | Dedicated endpoints |
| Graceful shutdown | Clean termination | Signal handling |
| Horizontal scale | Stateless design | No local state |
| Container-friendly | Small binaries | Release optimization |
Critical Constraints
Stateless Design
RULE: No local persistent state
WHY: Pods can be killed/rescheduled anytime
RUST: External state (Redis, DB), no static mut
Graceful Shutdown
RULE: Handle SIGTERM, drain connections
WHY: Zero-downtime deployments
RUST: tokio::signal + graceful shutdown
Observability
RULE: Every request must be traceable
WHY: Debugging distributed systems
RUST: tracing spans, opentelemetry export
Trace Down ↓
From constraints to design (Layer 2):
"Need distributed tracing"
↓ m12-lifecycle: Span lifecycle
↓ tracing + opentelemetry
"Need graceful shutdown"
↓ m07-concurrency: Signal handling
↓ m12-lifecycle: Connection draining
"Need health checks"
↓ domain-web: HTTP endpoints
↓ m06-error-handling: Health status
Key Crates
| Purpose | Crate |
|---|---|
| gRPC | tonic |
| Kubernetes | kube, kube-runtime |
| Docker | bollard |
| Tracing | tracing, opentelemetry |
| Metrics | prometheus, metrics |
| Config | config, figment |
| Health | HTTP endpoints |
Design Patterns
| Pattern | Purpose | Implementation |
|---|---|---|
| gRPC services | Service mesh | tonic + tower |
| K8s operators | Custom resources | kube-runtime Controller |
| Observability | Debugging | tracing + OTEL |
| Health checks | Orchestration | /health, /ready |
| Config | 12-factor | Env vars + secrets |
Code Pattern: Graceful Shutdown
use tokio::signal;
async fn run_server() -> anyhow::Result<()> {
let app = Router::new()
.route("/health", get(health))
.route("/ready", get(ready));
let addr = SocketAddr::from(([0, 0, 0, 0], 8080));
axum::Server::bind(&addr)
.serve(app.into_make_service())
.with_graceful_shutdown(shutdown_signal())
.await?;
Ok(())
}
async fn shutdown_signal() {
signal::ctrl_c().await.expect("failed to listen for ctrl+c");
tracing::info!("shutdown signal received");
}
Health Check Pattern
async fn health() -> StatusCode {
StatusCode::OK
}
async fn ready(State(db): State<Arc<DbPool>>) -> StatusCode {
match db.ping().await {
Ok(_) => StatusCode::OK,
Err(_) => StatusCode::SERVICE_UNAVAILABLE,
}
}
Common Mistakes
| Mistake | Domain Violation | Fix |
|---|---|---|
| Local file state | Not stateless | External storage |
| No SIGTERM handling | Hard kills | Graceful shutdown |
| No tracing | Can't debug | tracing spans |
| Static config | Not 12-factor | Env vars |
Trace to Layer 1
| Constraint | Layer 2 Pattern | Layer 1 Implementation |
|---|---|---|
| Stateless | External state | Arc<Client> for external |
| Graceful shutdown | Signal handling | tokio::signal |
| Tracing | Span lifecycle | tracing + OTEL |
| Health checks | HTTP endpoints | Dedicated routes |

DO NOT USE FOR: non-azd deployments, Python App Service code-only deploys (use python-appservice-deploy), or cross-cloud migration (use azure-cloud-migrate). WHEN: prepare app for azd, create azure.yaml, set up azd infrastructure, modernize app for Azure with azd, deploy with azd, function app, timer trigger, service bus trigger, event-driven function, managed identity, generate Bicep, generate Terraform, create and deploy to Azure.
