architecture-and-stack — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited architecture-and-stack (Agent Skill) and scored it 74/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 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.

Default stack: _kernel/standards.md#stack. Override conditions below.
Compute: Workers (default, every HTTP/cron/queue) · Pages (static-only marketing, rare) · Containers (non-JS runtimes: Playwright headful, ffmpeg, Python ML, build orchestration) · Sandbox SDK (generated/risky code before live promotion)
State: D1 (default relational, ≤10GB/db, Sessions API read-replicas, Time Travel 30-day PIT) · KV (eventually-consistent, cache/sessions/feature-flags) · R2 (object storage, lifecycle Standard→IA after 30d) · Durable Objects (coordination + strongly-consistent SQLite storage since Apr 2025, chat rooms/builder sessions/rate-limiting) · Hyperdrive (front external Postgres/MySQL) · Vectorize (semantic search/RAG, 5M dim/index, topK 100, 10 metadata indexes)
Async: Queues (best-effort, 5000 msg/sec, R2 event notifications) · Workflows v2 (deterministic, 50K concurrent, 300 creates/sec, 2M queued/workflow, step.do + step.sleep + step.waitForEvent) · Inngest (event-driven, better DX/observability)
AI: Workers AI (Llama 4 Scout 17B default — multimodal, free tier; GLM-4.7-flash tool-calling; 3.3 70B legacy) · AI Gateway (caching + rate-limit + fallback + logging for every LLM call) · Vectorize (embeddings + ANN search)
| Need | Fallback | Adapter |
|---|---|---|
| Advanced SQL (RLS, OLAP, partial indexes) | Neon Postgres via Hyperdrive | SqlPort |
| Redis primitives at scale (sorted sets, streams) | Upstash Redis | KvPort |
| Sub-millisecond global state | Upstash QStash | QueuePort |
| Specific provider (OpenAI assistants, Anthropic batch) | Direct API via AI Gateway | AiPort |
| Vector + SQL co-located | Neon pgvector | VectorPort |
Adapters live in libs/core/ports/. Product code imports port, never vendor SDK directly. See rules/cloudflare-hostable-supervisor.md.
