SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Debugging live failures that look correct in local tests by pinpointing the earliest decision point where the real system’s behavior diverges from your assumptions.

Core Features & Use Cases

  • Boundary-first diagnostics: Identify and instrument only the earliest plausible live boundary (artifact, config, routing/proxy, cache/CDN, feature flags, webhook target, or client/server divergence) to prove which source actually “wins.”
  • Minimal, removable probes: Add a single narrow diagnostic (e.g., a stable log marker or a header/payload field) that is easy to remove after verification.
  • Patch the winning point: Apply the fix only to the boundary that the evidence shows is responsible, then re-verify on the real/live path.

Quick Start

Use the debug-live-boundary skill by stating the exact contradiction between local tests and live behavior, then adding one narrow diagnostic at the earliest boundary that can distinguish the competing explanations.

FAQPage Schema
How do I debug live routing or cache failures when local tests pass?

Debug live routing or cache failures by tracing the earliest boundary decision point where the real system diverges from local assumptions, adding one narrow removable diagnostic to prove the winning source, patching only that boundary, and verifying on the live path.

What is a live boundary in production debugging?

A live boundary in production debugging is a decision point like artifact, config, routing, proxy, cache, CDN, feature flags, or webhook targets where the real system's behavior determines the observed outcome and diverges from local test results.

Why do repeated patch attempts not resolve staging or preview environment failures?

Repeated patch attempts fail because the boundary being patched is not the winning source. Prove which live boundary actually determines the outcome by instrumenting the earliest plausible point with a stable log marker before applying fixes.

How do I add diagnostics to a live system without causing side effects?

Add diagnostics to a live system by inserting a single narrow probe such as a stable log marker or header field at the earliest boundary, verifying the real path, and removing the instrumentation immediately after the winning source is proven.

Can I use this approach for webhook target and integration path failures?

Yes, this boundary-first diagnostic approach applies to webhook target, integration path, deployed API, client/server divergence, and build artifact failures by identifying the earliest live boundary that distinguishes competing explanations for the symptom.

What's the best way to trace configuration or build artifact discrepancies in production?

Trace configuration or build artifact discrepancies by choosing a single earliest live boundary, adding one removable narrow diagnostic to prove the winning source, patching only that specific boundary, and verifying the fix on the real production path.
