Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Generate comprehensive Functional Specification Documents (FSDs) that translate PRD requirements into implementation-ready specifications. Use when the user needs to create an FSD, functional spec, system specification, or detailed feature specification. Triggers on requests like "create an FSD", "write functional specifications", "translate this PRD into specs", or any request to define system behaviors, data requirements, business rules, and acceptance criteria from a PRD or feature description.Key capabilities
- →Translate PRD requirements into implementation-ready functional specifications
- →Define system behaviors and data requirements
- →Identify and list acceptance criteria using Given-When-Then format
- →Prioritize features using MoSCoW (Must/Should/Could/Won't)
- →Generate Global FSDs including system architecture and global business rules
- →Produce Feature FSDs detailing functional logic, UI states, and validation rules
How it works
The skill analyzes a PRD or context, extracts key information, and generates an FSD by applying specific writing rules and structuring the document based on whether it's a global or feature FSD.
Inputs & outputs
When to use FSD Generator
- →Creating fsd from prd
- →Writing feature specifications
- →Defining system business rules
About FSD Generator
Creates detailed FSDs. It maps business requirements to technical specs, defines behaviors, and identifies acceptance criteria.

When not to use it
- →When the user needs a Product Requirements Document (PRD)
- →When the task is not related to defining system behaviors or data requirements
- →When the output is not intended for development teams
Limitations
- →Every FSD item must map to a PRD requirement
- →The skill identifies vague requirements as "Open Questions"
- →The skill focuses on generating FSDs from PRD requirements
How it compares
This skill automatically generates a structured FSD with precise language and specific sections like atomic business rules and traceability matrices, unlike manually drafting a document.
