SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Diagnose and resolve production-like bugs with an evidence-first, TDD-oriented workflow that audits coverage from backend payload to final UI rendering.

Core Features & Use Cases

  • End-to-end failure tracing: Map the symptom to backend, DTO, UI and verify the failure chain with concrete data.
  • TDD-driven resolution: Prefer failing tests, minimal fixes, and regression tests to prevent false greens.
  • Delivery governance: Align fixes with TODOs, analyzer rules, and sign-off gates to ensure durable improvements.

Quick Start

Analyze a failing scenario, reproduce it deterministically, and draft a minimal fix that is verified by added tests.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I trace an end-to-end failure from backend payload to UI rendering?▼

Fix UI rendering bugs by mapping the failure chain from backend payload through DTO to the UI layer. You must verify the failure path using concrete data before drafting a minimal fix.

What is the best way to deterministically reproduce a production-like bug?▼

Deterministically reproduce a production-like bug by capturing concrete data from the failing scenario. This workflow requires mapping the exact failure chain to establish a reliable reproduction before writing any fixes.

How do I apply TDD to verify a bug fix and prevent false greens?▼

Apply TDD to bug fixes by writing a failing test that reproduces the issue, drafting a minimal code fix, and adding regression tests. This test-driven verification workflow prevents false greens by confirming the test passes only after the fix.

Does this evidence-first debugging workflow require specific coverage mapping?▼

Yes, the evidence-first debugging workflow requires explicit coverage mapping. It audits the failure path from backend payload to UI rendering, ensuring mandatory questions and deterministic reproduction are satisfied before resolving the root cause.

How do I align bug fixes with delivery governance and sign-off gates?▼

Align bug fixes with delivery governance by mapping resolutions to TODOs, analyzer rules, and sign-off gates. This ensures durable improvements by enforcing strict governance constraints throughout the end-to-end debugging workflow.
