Cloudflare Knowledge Skill

Comprehensive Cloudflare platform knowledge covering Workers, edge storage, AI, MCP, and Zero Trust. Acts as a lean orchestrator over deep references in references/.

Activation Triggers

Activate this skill when users ask about:

  • Cloudflare Workers development, Wrangler CLI, wrangler.jsonc configuration
  • Storage services (R2, D1, KV, Durable Objects, Queues, Hyperdrive)
  • Workers AI inference (LLM, TTS, STT, image, embeddings, vision)
  • MCP server development on Workers
  • Zero Trust (tunnels, WARP, Access policies)
  • Workflows and durable execution, Vectorize, Pages, cron triggers
  • CI/CD with GitHub Actions or Workers Builds
  • Observability, load balancing, cost optimization

Reference Map

Load only the reference(s) the current task needs:

Platform Overview

Cloudflare is a global edge computing platform with 300+ data centers providing:

  • Workers — Serverless JavaScript/TypeScript/Python/WASM at the edge
  • Pages — Static site and full-stack app hosting
  • R2 — S3-compatible object storage with zero egress fees
  • D1 — Serverless SQLite database (strongly consistent, 10 GB max)
  • KV — Eventually consistent key-value store
  • Durable Objects — Stateful coordination with WebSocket Hibernation
  • Queues — Async message processing with DLQ
  • Hyperdrive — Database connection pooling for remote Postgres/MySQL
  • Workers AI — LLM/TTS/STT/image/embeddings/vision at the edge
  • Zero Trust — Identity-based security platform
  • Vectorize — Vector database for RAG
  • Workflows — Durable multi-step execution

Core Workflow

  1. Scaffold — npm create cloudflare@latest then npx wrangler login. Wrangler CLI details: wrangler-cli-and-config.md.
  2. Pick a storage primitive — KV for config/sessions, R2 for blobs, D1 for relational, Durable Objects for coordination, Queues for async, Hyperdrive for remote SQL. Characteristics and trade-offs: storage-services-deep-dive.md.
  3. Add bindings to wrangler.jsonc — KV namespaces, R2 buckets, D1 databases, DO, Queues, AI, Vectorize, service bindings, cron triggers, routes, observability. Full schema: wrangler-cli-and-config.md.
  4. Implement handlers — fetch, scheduled, queue, email. Per-binding APIs: storage-services-deep-dive.md. AI invocations: ai-workers-usage.md.
  5. Develop locally — npx wrangler dev (use --remote for remote bindings; trigger crons via /__scheduled?cron=*+*+*+*+*).
  6. Deploy — npx wrangler deploy [--env staging]. Roll back with npx wrangler rollback. CI/CD recipes (GitHub Actions, Workers Builds): wrangler-cli-and-config.md.

Quick Decision Guide

| Task | Choice | Reference | |------|--------|-----------| | Store user sessions, config flags | KV (eventually consistent) | storage-services-deep-dive.md | | Store media, backups, datasets | R2 (zero egress, 5 TB objects) | storage-services-deep-dive.md | | Relational queries, ACID | D1 (SQLite, strong consistency) | storage-services-deep-dive.md | | Real-time coordination, chat, counters | Durable Objects (+ WebSocket Hibernation) | storage-services-deep-dive.md | | Background jobs, decoupling | Queues (at-least-once, DLQ) | storage-services-deep-dive.md | | Remote Postgres/MySQL with low latency | Hyperdrive | storage-services-deep-dive.md | | LLM/embedding/TTS/STT at the edge | Workers AI | ai-workers-usage.md + ai-workers-models.md | | Expose internal app without opening firewall | Cloudflare Tunnel (cloudflared) | ai-workers-usage.md (quickstart) + zero-trust-setup.md (production) | | Build MCP server on Workers | @cloudflare/mcp-server | ai-workers-usage.md (quickstart) + mcp-server-development.md (deep) | | Integrate Stripe, OpenAI, GitHub, etc. | Third-party API patterns | third-party-integrations.md | | Plan budget vs AWS/Azure/GCP | Pricing comparison | cost-comparison.md |

Best Practices

Performance

  1. Use edge caching — cache API responses via caches.default.
  2. Minimize cold starts — keep Workers small, prefer dynamic imports.
  3. Use Service Bindings — zero-cost Worker-to-Worker calls.
  4. Batch operations — combine KV/R2/D1 operations.
  5. Use Hyperdrive for remote PostgreSQL/MySQL.

Security

  1. Use wrangler secret put for credentials, never hardcode.
  2. Validate and sanitize all user input.
  3. Always use HTTPS; enforce on routes.
  4. Implement rate limiting (Workers Rate Limiting API or WAF rules).
  5. Use Zero Trust Access for internal services (see zero-trust-setup.md).

Cost Optimization

  1. Use Static Assets (free, unlimited static file serving).
  2. Sample logs via observability.logs.head_sampling_rate for high-traffic Workers.
  3. Use KV/R2 for caching to reduce D1 or external API calls.
  4. Batch Queue messages to reduce per-message overhead.
  5. Choose model size to fit task in Workers AI — see ai-workers-models.md.
  6. Full pricing tables and cross-cloud comparison: cost-comparison.md.
