### 1. Problem & Operational Bottleneck Port legacy GraphQL queries to end-to-end typed tRPC procedures route-by-route with automated response parity tests. Built and battle-tested in production workflows by **@vercel** (Vercel Engineering). ### 2. Target Architecture & Required Stack - **GitHub MCP** - **Playwright MCP** - **Sentry MCP** ### 3. Step-by-Step Implementation Blueprint 1. Configure and authenticate the required MCP connectors (GitHub MCP, Playwright MCP, Sentry MCP) in your agent workspace. 2. Run the initial read-only inspection pass for 'Incremental GraphQL-to-tRPC Strangler Fig Migration' 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. ### 4. Copy-Paste Agent Execution Prompt ```markdown Run the 'Incremental GraphQL-to-tRPC Strangler Fig Migration' (graphql-to-trpc-incremental-strangler-migration) implementation blueprint using GitHub MCP, Playwright MCP, Sentry MCP. Objective: Port legacy GraphQL queries to end-to-end typed tRPC procedures route-by-route with automated response parity tests. 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. ``` ### 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.
