### 1. Problem & Operational Bottleneck Validate PostHog and Segment tracking calls in PR diffs against a central JSON Schema registry so analytics pipelines never break. Built and battle-tested in production workflows by **@kentcdodds** (Kent C. Dodds (@kentcdodds)). ### 2. Target Architecture & Required Stack - **PostHog MCP** - **GitHub MCP** - **Slack MCP** ### 3. Step-by-Step Implementation Blueprint 1. Connect PostHog MCP, GitHub MCP, Slack MCP and verify read-only access to the target workspace. 2. Run the discovery query for 'Analytics Event Schema Contract & Breaking-Change CI Gate' 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 'Analytics Event Schema Contract & Breaking-Change CI Gate' (data-json-schema-registry-and-event-contract-gate) blueprint with PostHog MCP, GitHub MCP, Slack MCP. Goal: Validate PostHog and Segment tracking calls in PR diffs against a central JSON Schema registry so analytics pipelines never break. 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.
