SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps you quickly determine technical feasibility, determine a design approach, and produce customer-facing summaries plus implementer-ready design docs from a requirements document (readme.md or spec).

Core Features & Use Cases

  • Assess feasibility within 30–40 minutes and generate two artifacts: a customer-facing summary and a technical design doc for developers.
  • Step through requirements, identify uncertainties, and propose phased delivery with rough man-days and a plan.
  • Suitable for when a client asks β€œcan you estimate this?” or when you receive a readme/spec and must produce binding estimates and plans.

Quick Start

Provide a concise feasibility judgment, design direction, and effort estimate from the given requirements document.

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

FAQPage Schema
How do I estimate project feasibility and effort from a requirements document?β–Ό

To estimate project feasibility from a requirements document, you can identify design direction and produce a rough man-day total with a 20–30% buffer. This involves generating a customer-facing summary and an implementer-ready design document.

What is the best way to determine technical feasibility from a readme or specification?β–Ό

Determining technical feasibility from a specification involves stepping through requirements to identify uncertainties and propose a phased delivery plan. This process yields a clear yes, no, or conditional feasibility judgment along with rough man-day estimates.

Can I generate a phased delivery plan and design doc from a requirements brief?β–Ό

Yes, you can generate a phased delivery plan and design doc from a requirements brief. The process assesses the brief to produce both a customer-facing summary and a technical design document tailored for developers.

How long does it take to assess requirements and produce a binding project estimate?β–Ό

Assessing requirements to produce binding project estimates typically takes 30 to 40 minutes. This timeframe allows for identifying feasibility, proposing a design direction, and outputting rough man-day totals with a buffer.

What outputs should I expect when estimating effort from a design spec?β–Ό

When estimating effort from a design spec, you should expect two distinct outputs: a customer-facing summary and a technical design document for implementers. Both outputs include a clear feasibility judgment and a phased plan.

Does project planning from a scenario brief require adding a man-day buffer?β–Ό

Yes, project planning from a scenario brief requires adding a 20 to 30 percent buffer to the rough man-day total. This buffer accommodates identified uncertainties and ensures the phased delivery plan remains realistic.
