The Functional Requirements Specification Builder is a skill published by agensi for generating structured technical documentation suitable for procurement and compliance contexts. It targets developers, GRC professionals, and procurement teams who need to produce FRS and FPS documents, non-functional requirements, and technical annexes from supplied source materials.

The skill enforces a systematic drafting workflow that requires confirmation of Tier 1 inputs — such as procurement objectives and deployment context — before any output is generated. This prevents drafting from proceeding without the information needed to produce auditable, traceable requirements.

Source materials such as legacy specifications, SOPs, and compliance frameworks are parsed to derive testable obligations. Every requirement in the output is assigned a unique reference code, a priority classification (Mandatory, Conditional, or Desirable), and a traceable source reference, making the documents ready for vendor response cycles.

Quality control is applied through eight distinct Quality Gates and materiality assessments ranging from Low to High. Outputs are produced in structured Markdown or documentation-ready text and include document control tables, exclusion registers, and validation point logs for missing data. The skill maintains British English throughout, matching the formal register expected for RFP, RFQ, and legal review processes.

Use cases

Generate a full Functional Requirements Specification from existing SOPs and compliance frameworks

Produce non-functional requirements annexes for a procurement tender

Parse legacy specifications to derive traceable, testable obligations

Create RFP-ready documentation with unique reference codes and priority classifications

Build document control tables and exclusion registers for project uploads

Validate input completeness before drafting begins to avoid gaps in requirements

When to use it

When producing formal procurement documentation such as RFPs or RFQs that require auditable, traceable requirements

When source materials like SOPs or legacy specs must be systematically converted into testable obligations

When outputs need British English and a formal register suitable for legal review

When GRC or compliance workflows require structured Quality Gate assessments

When not to use it

When no source materials are available to supply as Tier 1 inputs, as the skill requires these before drafting

When informal or rapid requirements notes are needed rather than formal procurement documentation

When the target format is not Markdown or documentation-ready text

When requirements are for a non-procurement engineering context that does not use RFP/RFQ structures
