SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill bridges the gap between vague product requirements and actionable engineering tasks by forcing the definition of constraints, invariants, and interfaces before implementation begins.

Core Features & Use Cases

  • Constraint Mapping: Identifies hidden assumptions, business rules, and technical boundaries early in the development lifecycle.
  • Contract Definition: Generates an SRS-style capability plan that serves as a durable artifact for cross-team alignment.
  • Use Case: When a new feature spans multiple services, use this skill to define the exact data ownership, security boundaries, and failure expectations to prevent mid-implementation drift.

Quick Start

Use the product-capability skill to analyze the requirements in the attached PRD and generate an implementation-ready capability contract.

FAQPage Schema
How do I translate product requirements into engineering constraints?

To translate product requirements into engineering constraints, you analyze roadmap intent to identify hidden assumptions, business rules, and technical boundaries. This process generates an SRS-style capability plan defining data ownership and technical interfaces for implementation.

What is capability mapping for multi-service feature development?

Capability mapping for multi-service feature development is the process of defining exact data ownership, security boundaries, and failure expectations across services. It creates durable documentation of business rules to prevent mid-implementation drift.

How do I generate an implementation-ready capability contract from a PRD?

You generate an implementation-ready capability contract from a PRD by applying constraint mapping to the attached requirements. This identifies implicit assumptions and outputs an SRS-style plan serving as a durable artifact for cross-team alignment.

When do I need to define SRS constraints and invariants before implementation?

You need to define SRS constraints and invariants before implementation when a new feature spans multiple services. This early architectural design phase practice prevents delivery risks caused by implicit assumptions and mid-implementation drift.

Does this approach work for architectural design and cross-team alignment?

Yes, this approach works for architectural design and cross-team alignment by generating durable, reusable documentation. It bridges vague product intent and actionable engineering tasks through explicit contract definition and technical interface boundaries.

What is the best way to prevent mid-implementation drift in multi-service features?

The best way to prevent mid-implementation drift in multi-service features is to map constraints and define contracts before coding begins. Forcing the definition of invariants and interfaces creates a durable SRS-style artifact for cross-team alignment.
