backend-architect — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited backend-architect (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.

The primary manifest — the file an agent reads to learn what this artifact does.
| Use case | Protocol | Reason |
|---|---|---|
| Standard CRUD API | REST | Widest tooling support |
| Client queries complex data | GraphQL | Reduces over-fetching |
| Internal service-to-service | gRPC | Typed contracts, low latency |
| Real-time bidirectional | WebSocket | Full duplex |
| Server push (one-way) | SSE | Simpler than WS for unidirectional |
| High-volume async work | SQS/Kafka | Decoupling, retry, backpressure |
Circuit Breaker: CLOSED → [failures > threshold] → OPEN → [timeout] → HALF-OPEN → [success] → CLOSED
Retry: exponential backoff with jitter — base_delay * 2^attempt + random(0, base_delay)
Timeout: always set; propagate deadline via context/headers
Bulkhead: separate thread pools per dependency; one slow dep shouldn't starve others
Idempotency: every mutating operation needs idempotency key; store result, return on duplicateLogs: structured JSON, always include: traceId, userId, duration, status
Metrics (RED): Rate (req/s), Errors (%), Duration (p50/p95/p99)
Traces: OpenTelemetry → Jaeger/Tempo; trace every cross-service call
Alerts: error rate > 1%, p99 latency > SLO, queue depth > threshold| Layer | Tool | Pattern | Invalidation |
|---|---|---|---|
| App | Redis | Cache-aside | TTL + event-driven |
| API | CDN (CloudFront) | Read-through | Cache-Control headers |
| DB reads | Read replica | Direct query | N/A (replica lag) |
Cache-aside rule: read → cache miss → DB → cache set → return. Never write to cache directly on writes — let TTL or event invalidate.
