Copy-Paste System Prompt / Routine Blueprint:
Run the 'Zero-Downtime Cloudflare D1 Read-Replica & Worker Cutover' (multi-region-cloudflare-d1-read-replica-cutover) implementation blueprint using Cloudflare MCP, Wrangler CLI, D1 SQLite. Objective: Migrate high-traffic API routes to Cloudflare Workers + D1 with automated row-count parity checks and gradual traffic shifting. Step 1: Perform a read-only audit of current state and recent logs. Step 2: Generate a deterministic execution plan with exact diffs, SQL/CLI commands, or drafted payloads. Step 3: Request human confirmation before applying any production writes or external sends.
Synthesized Engineering Blueprint & Setup Guide
### 1. Problem & Operational Bottleneck
Migrate high-traffic API routes to Cloudflare Workers + D1 with automated row-count parity checks and gradual traffic shifting. Built and battle-tested in production workflows by **@steipete** (Peter Steinberger (@steipete)).
### 2. Target Architecture & Required Stack
- **Cloudflare MCP**
- **Wrangler CLI**
- **D1 SQLite**
### 3. Step-by-Step Implementation Blueprint
1. Configure and authenticate the required MCP connectors (Cloudflare MCP, Wrangler CLI, D1 SQLite) in your agent workspace.
2. Run the initial read-only inspection pass for 'Zero-Downtime Cloudflare D1 Read-Replica & Worker Cutover' to gather baseline telemetry, schemas, and context.
3. Execute the multi-step analysis and transformation pipeline with strict schema validation and zero fabricated identifiers.
4. Review the staged diff or approval card and verify completion via automated regression and status checks.

### 5. Verification & Safety Guardrails
- **Human-in-the-Loop Gate:** All external communications, production database mutations, and billing actions stage an explicit review diff before execution.
- **Deterministic Telemetry:** Every run logs structured JSON output, latency metrics, and source citations so operators can audit every decision.
