SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Specification gaps, conflicts, and ambiguities are often only discovered late in the development process during implementation, leading to costly rewrites, delayed launches, and wasted engineering effort. This skill enables you to identify these issues early using LLM reasoning, before any code is written, reducing risk and rework.

Core Features & Use Cases

  • Scenario-based spec validation: Simulate real-world user journeys against your specification documents to trace cross-cutting requirements and surface missing definitions.
  • Structured gap reporting: Classify findings by severity (BLOCKING, DEGRADED, COSMETIC) to prioritize fixes, and generate spec coverage matrices to identify untested documentation.
  • Use case: Before starting build work on a new e-commerce checkout flow, run vibe tests to catch gaps like mismatched payment retry timing and inventory hold durations that would otherwise cause mid-implementation surprises.

Quick Start

Ask your AI coding agent to run a vibe test on your project's specification documents to identify gaps and ambiguities before you begin writing implementation code.

FAQPage Schema
How do I catch specification gaps before writing code?

To catch specification gaps before writing code, run LLM-reasoning simulations of real-world user scenarios against your spec documents. This pre-implementation review surfaces missing definitions and conflicts early, producing structured gap reports with severity classifications.

What is specification testing and how does it work?

Specification testing validates documents for completeness and consistency by simulating real-world user journeys against them. It uses LLM reasoning to trace cross-cutting requirements and identify ambiguities before implementation begins.

Can I test cross-document coherence for systems with multiple specification files?

Yes, you can perform cross-document coherence checks across multiple interconnected specification files. The simulation maps dependencies between documents to ensure consistency and identify conflicting definitions across the system.

How do I prioritize specification updates after finding gaps?

Prioritize specification updates using structured gap reports that classify findings by severity as BLOCKING, DEGRADED, or COSMETIC. You also receive spec coverage matrices to identify untested documentation and focus your required updates.

When should I run spec validation on my project?

Run spec validation during pre-implementation review before writing code, after post-spec changes for regression testing, or when checking cross-document coherence. This timing prevents costly rewrites and delayed launches caused by late-stage gap discovery.
