### 1. Problem & Operational Bottleneck Run recorded consumer request fixtures against staging API builds to guarantee zero unannounced breaking changes in JSON responses. Built and battle-tested in production workflows by **@mattpocockuk** (Matt Pocock (@mattpocockuk)). ### 2. Target Architecture & Required Stack - **GitHub MCP** - **Playwright MCP** - **Slack MCP** ### 3. Step-by-Step Implementation Blueprint 1. Connect GitHub MCP, Playwright MCP, Slack MCP and verify read-only access to the target workspace. 2. Run the discovery query for 'Multi-Version API Contract & Consumer Compatibility Matrix' to establish baseline metrics and identify anomalies. 3. Generate a structured remediation or execution artifact with full source citations and diffs. 4. Stage any mutating actions behind an explicit human approval gate and verify final state. ### 4. Copy-Paste Agent Execution Prompt ```markdown Execute the 'Multi-Version API Contract & Consumer Compatibility Matrix' (qa-api-contract-backward-compatibility-matrix) blueprint with GitHub MCP, Playwright MCP, Slack MCP. Goal: Run recorded consumer request fixtures against staging API builds to guarantee zero unannounced breaking changes in JSON responses. First inspect live state in read-only mode, validate all identifiers and metrics, and output a concrete action plan with verification commands before making any changes. ``` ### 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.
